] | I'm trying to add some custom HTML to specific WooCommerce products for my client. I successfully learned to add this custom HTML to all product pages at once (more specifically to their descriptions, overriding short-description.php) but I only need products A, B and C to contain this HTML bit and the rest to stay with the default content. A, B and C are in the same product category. How would you narrow the products, via category or product by product, that will contain this HTML, please? | First off, it's always good to register shortcode during `init` versus just in your general `functions.php` file. At the very least `add_shortcode()` should be in `init`. Anyway, let's begin!
Whenever you use [`add_shortcode()`](https://codex.wordpress.org/Function_Reference/add_shortcode) the first parameter is going to be the name of the shortcode and the 2nd will be the callback function. This means that:
```
[products line="prime"]
```
Should be instead:
```
[produtos line="prime"]
```
So far we have this:
```
/**
* Register all shortcodes
*
* @return null
*/
function register_shortcodes() {
add_shortcode( 'produtos', 'shortcode_mostra_produtos' );
}
add_action( 'init', 'register_shortcodes' );
/**
* Produtos Shortcode Callback
* - [produtos]
*
* @param Array $atts
*
* @return string
*/
function shortcode_mostra_produtos( $atts ) {
/** Our outline will go here
}
```
Let's take a look at processing attributes. The way [`shortcode_atts()`](https://codex.wordpress.org/Function_Reference/shortcode_atts) works is that it will try to match attributes passed to the shortcode with attributes in the passed array, left side being the key and the right side being the defaults. So we need to change `defaults` to `line` instead - if we want to default to a category, this would be the place:
```
$atts = shortcode_atts( array(
'line' => ''
), $atts );
```
IF the user adds a attribute to the shortcode `line="test"` then our array index `line` will hold `test`:
```
echo $atts['line']; // Prints 'test'
```
All other attributes will be ignored unless we add them to the `shortcode_atts()` array. Finally it's just the WP\_Query and printing what you need:
```
/**
* Register all shortcodes
*
* @return null
*/
function register_shortcodes() {
add_shortcode( 'produtos', 'shortcode_mostra_produtos' );
}
add_action( 'init', 'register_shortcodes' );
/**
* Produtos Shortcode Callback
*
* @param Array $atts
*
* @return string
*/
function shortcode_mostra_produtos( $atts ) {
global $wp_query,
$post;
$atts = shortcode_atts( array(
'line' => ''
), $atts );
$loop = new WP_Query( array(
'posts_per_page' => 200,
'post_type' => 'produtos',
'orderby' => 'menu_order title',
'order' => 'ASC',
'tax_query' => array( array(
'taxonomy' => 'linhas',
'field' => 'slug',
'terms' => array( sanitize_title( $atts['line'] ) )
) )
) );
if( ! $loop->have_posts() ) {
return false;
}
while( $loop->have_posts() ) {
$loop->the_post();
echo the_title();
}
wp_reset_postdata();
}

How do I go about determining which plugin (and which page/line of that plugin) is causing this? Is there a mechanism in place, or do I have to trial and error it? | In your [`wp-config.php`](https://codex.wordpress.org/Debugging_in_WordPress) make sure to include;
```
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', true );
```
Sometimes your environment will do a better job at outputting the stack trace.
If that doesn't work, you can go that line in WP core and add;
```
$backtrace = debug_backtrace();
print('<pre>');
print_r ( $backtrace );
```
That should give you a lot more information to go off of, for example;
```

How to edit the regular expression is not my concern, but where to make the edit to insert the regular expression is what would like to know.
Is there some kind of filter that I can use on post submission? | `save_post` didn't work for me.
What works in my situation is using [content\_save\_pre](https://codex.wordpress.org/Plugin_API/Filter_Reference/content_save_pre) filter or the content processing before save.
Since I'm using `Advanced Custom Field` plugin for my `cover_image` field, and I ended up using `acf/save_post` filter to process the field. |

Please help me and guide the best way to do it.
Thanks | I've checked and WordPress does, by default, retrieve & cache all post meta along with the main query's posts, so you're perfectly fine storing a product's additional fields as standard post meta.
You might want to store Brands (merchants? manufacturers?) as a custom taxonomy so that you can take advantage of built-in templates and queries to show all products of a certain brand. |
233,065 | <p>Normally when you set a custom image size using hard crop - e.g. <code>add_image_size( 'custom-size', 400, 400, true );</code> - you get the following results:</p>

<li>#1 Uploaded image: 600x500 > Thumbnail: 400x400.</li>
<li>#2 Uploaded image: 500x300 > Thumbnail: 400x300.</li>
<li>#3 Uploaded image: 300x200 > Thumbnail: 300x200.</li>
</ul>
<p>However what I'd like to do is when the uploaded image is smaller than the set width, or height, or both, of the custom image size, e.g. examples #2 & #3 above - instead of the image just being cropped to fit within those dimensions - it's also cropped to match their aspect ratio (which in this case is 1:1) like so:</p>
<ul>
<li>#1 Uploaded image: 600x500 > Thumbnail: 400x400.</li>
<li>#2 Uploaded image: 500x300 > Thumbnail: <strong>300x300</strong>.</li>
<li>#3 Uploaded image: 300x200 > Thumbnail: <strong>200x200</strong>.</li>

<p>I don't believe this is possible using the standard add_image_size options, but is it possible using a different function, or hook that modifies the add_image_size function?</p>

Any information anyone can provide would be greatly appreciated. | You're right that it just doesn't work like that.
If it's OK to think of your question the other way around though, you can get the right outcome in modern browsers using a selection of image sizes and responsive images.
If you use code like this:
```
add_image_size( 'custom-size-small', 200, 200, true );
add_image_size( 'custom-size-medium', 300, 300, true );
add_image_size( 'custom-size-large', 400, 400, true );
```
... and in your templates something like:
```
wp_get_attachment_image( $image_ID, 'custom-size-small' )
```
... then by default (WP 4.4 and later) you will get an image tag with the smallest version from your set as the `src` and the larger sizes in the `srcset` attribute, which newer browsers will pick from and display the largest appropriate version.
So then, if a particular image doesn't have a larger version, it doesn't matter. An image that is `300x200` will have a `200x200` version made, that version will be the only one in the HTML and all browsers will show it.
I worked this out while tweaking responsive images so that I get good performance on browsers that only support `src` and not `srcset`. |

] | In my loop, I have ten posts with the following categories (slug): group-a, group-a-first and group-b. The loop/query looks like this:
* Post (group-a)
* Post (group-b)
* Post (group-a-first)
What's the best way to check if those posts has a specific category?
I've tried `<?php if(in_category('group-a')) ;?>`, it does work but it checks every post so I three results: yes, no, no, etc.
What I'm looking for if any post in the loop has a specific category, it outputs either a yes or no.

Thanks, | You can just run through the loop and set a flag:
```
if ( $query->have_posts() ) :
$any_in_cat = false;
while ( $query->have_posts() ) : $query->the_post();
if ( in_category( 'first-major' ) ) :
$any_in_cat = true;
endif;
endwhile;
$query->rewind_posts();
/* if $any_in_cat == true at this point then at least one
of the posts has the category 'first-major'
*/
if( true == $any_in_cat ) {
echo 'true';
} else {
echo 'false';
}
```
I've added your conditional check. Note that it is all PHP, so you don't want the opening and closing tags where you have them in your comment. I prefer the brace notation myself as it suits every case of nested conditionals and is really clear to read. Lastly you need the double-equals sign to test equality. `=` is the assignment operator, so when you say `if ( $any_in_cat = true )` then you are setting `$any_in_cat` to `true` and also the condition will always be `true`. Even `if ( $any_in_cat = false )` is `true` because you are testing the success of the assignment. It's a slip we all make and is easier to debug if you get in the habit of writing the condition as `if( true == $any_in_cat )` Then if you slip and use a single `=` you'll get an error message as you can't make an assignment to `true`.
You're re-running your loop several times, so it might be possible to simplify your code somewhat too, but that's another question and not directly WP related. |

] | I would like to change the priority/menu order of the "Media" admin page. Is there a way to change that via apply\_filter?
Is there a way to change only "Media" page priority without having to list all pages within menu\_order?
Thanks | There's a combination of two filters, `menu_order` does the job, but you also use `custom_menu_order` to enable `menu_order`.
```
function wpse_233129_custom_menu_order() {
return array( 'index.php', 'upload.php' );
}
add_filter( 'custom_menu_order', '__return_true' );
add_filter( 'menu_order', 'wpse_233129_custom_menu_order' );
```
This will put upload.php (the Media screen) just after the Dashboard and then the other top-level menu items will follow.
If you want to put Media elsewhere then just list all the other screens that should precede it in the array.
Alternatively you could directly address WP's global $menu array:
```
function wpse_233129_admin_menu_items() {
global $menu;
foreach ( $menu as $key => $value ) {
if ( 'upload.php' == $value[2] ) {
$oldkey = $key;
}
}
$newkey = 26; // use whatever index gets you the position you want
// if this key is in use you will write over a menu item!
$menu[$newkey]=$menu[$oldkey];
$menu[$oldkey]=array();
}
add_action('admin_menu', 'wpse_233129_admin_menu_items');
```
Note the comment on the possibility of overwriting another menu item. Coding in a search for an array index that doesn't collide is left as an exercise for the reader. This isn't an issue if you use the first method, of course.
There's something about fiddling with WP's globals like this that makes me feel dirty. Changes to WP's inner workings can mess things up for you. Use the abstractions provided by hooks and APIs when you can. |

Thanks! | You are using `get_stylesheet_uri()` which links directly to your stylesheet, then your adding /style.css which is resulting in an invalid url.
So you need to remove the `/style.css`.
Or use `get_stylesheet_directory_uri()` and leave the `/style.css` on there. |

Look in your SQL for a section starting with:
```
INSERT INTO `wp_posts` VALUES
```
and eventually ending with a semicolon.
This is all of your post data. Hopefully you have one line for each post otherwise this will be very hard. **This does not include any categories, tags or custom fields.**
You will hopefully see lines starting something like this:
```
INSERT INTO `wp_posts` VALUES (1,1,'2015-03-03 11:42:37','20

You "simply" (and this can be slow, careful work) want to delete the lines which have hacked data in. Any line that doesn't look like your original post can go.
Examining one of those lines in detail and formatting it to see what's what:
```
INSERT INTO `wp_posts` VALUES (
1, -- this is the Post ID
1, -- this is the author ID
'2015-03-03 11:42:37', -- post date
'2015-03-03 11:42:37', -- post date in GMT
```
and then:
```
'Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!',
```
That field is your post content. If that looks like you don't want it in your database then delete the *whole line* from `(` up to `),`
```
'Hello world!', -- Post title
'', -- Excerpt
'publish', -- status - all live posts will have "publish" here
-- and so on
'open','open','','hello-world','','',
'2015-03-03 11:42:37','2015-03-03 11:42:37',
'',0,'http://testsite.localhost/?p=1',0,'post','',1),
```
If any fields have something in that isn't plain English (if English your posts are) or clearly a simple value, date or URL related to your site then get rid of the line.
While doing this manually can be done, if there are many posts I would really consider getting someone who knows their way around WP & MySQL to clean the data for you. (Not me at the moment, I should add!!)
Backup your clean site before trying to import records just in case.
Good luck! |

```
update_user_meta( $user_id, 'mycoverimage', $_POST[ 'mycoverimage' ] );
```
The image was saved without generating attachment metadata. In fact, checking my table, it got only `usermeta id` which is not the attachment id. So I had to change a bit my uploading function according to [codex](https://codex.wordpress.org/Function_Reference/wp_insert_attachment) with the use of `wp_insert_attachment` like:
```
add_action( 'personal_options_update', 'save_cover_image' );
add_action( 'edit_user_profile_update', 'save_cover_image' );
function save_cover_image( $user_id ) {
if ( !current_user_can( 'edit_user', $user_id ) )
{
return false;
}
$filename = $_POST['mycoverimage'];
$parent_post_id = 0;
$filetype = wp_check_filetype( basename( $filename ), null );
$wp_upload_dir = wp_upload_dir();
$attachment = array(
'guid' => $wp_upload_dir['url'] . '/' . basename( $filename ),
'post_mime_type' => $filetype['type'],
'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
'post_content' => '',
'post_status' => 'inherit',
'post_author' => $uid
);
$attach_id = wp_insert_attachment( $attachment, $filename, $parent_post_id );
require_once( ABSPATH . 'wp-admin/includes/image.php' );
$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
wp_update_attachment_metadata( $attach_id, $attach_data );
update_user_meta( $user_id, 'mycoverimage', $_POST[ 'mycoverimage' ] );
}
```
At this point I have a `usermeta id` and an `attachment id` which I can easily retrieve for thumbs and other operations. Thanks to @majick anyway. |

<p>Well, with this I see in my <code>console.log</code> that <strong>No Object Properties</strong> and values are sent. Furthermore the <strong>json response is Nan</strong>.

Am I missing something? Any suggestion would be more than appreciated!</p>

I call this modal with `<?php do_action('change_avatar', $myuid ); ?>` in my page and I send the infos through AJAX, enqueuing the action like this (functions.php)
```
add_action('wp_ajax_update_avatar_function', 'update_avatar_function', 10, 2 );
function update_avatar_function(){
$pid = $_POST['pid'];
$uid = $_POST['uid'];
$avatar = $_POST['avatar'];
//perform update user meta and other stuff
//send me back uid and pid to check if they're correct
$response = array('uid'=>$uid,'pid'=>$pid);
echo json_encode($response);
die();
}
add_action( 'wp_enqueue_scripts', 'add_frontend_ajax_javascript_file', 10, 2 );
function add_frontend_ajax_javascript_file()
{
wp_localize_script( 'ajax-script', 'ajaxobject', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}
```
At the latest I use this jQuery/AJAX:
```
var updatebuttonav = $('#upload-avatar');
updatebuttonav.on('click', function() {
event.preventDefault();
update_avatar();
});
function update_avatar()
{
var form_data = new FormData($('form#change-avatar')[0]);
form_data.append('pid', $('#pid').val()), //no sending value
form_data.append('uid', $('#uid').val()), //no sending value
form_data.append('avatar', $('#input-avatar')[0].files[0]), //no sending file
form_data.append('action', 'update_avatar_function'),
console.log(form_data); //here is printing No Properties
jQuery.ajax({
method: 'post',
url : ajaxurl,
dataType: 'json',
data: form_data,
processData: false,
beforeSend:function(data){
//other functions
},
success:function(data) {
alert(data.uid + data.pid);
},
error: function(data){
console.log(data);
}
});
//alert("a");
}
```
Well, with this I see in my `console.log` that **No Object Properties** and values are sent. Furthermore the **json response is Nan**. I use this method with other section of my website and I can't see why here It's not working. Is that possible that through `do_action` the form is not seen?
Am I missing something? Any suggestion would be more than appreciated!

'meta_query' => array(

'key' => 'priority',

The real issue with your query is because you are passing `meta_key` and `meta_value`. However, the arrays in your `meta_query` argument should have the keys `key` and `value` instead.
This would also work:
```
'key' => 'priority',
'value' => array('80')

However, this is just returning an empty array. What am I missing? | Correct the `wp_get_themes()` function has most of the information inaccessible to the public which requires you to pull the info out using the `$theme->get( 'Name' );` format. You can build a simple array like so.
```
// Build new empty Array to store the themes
$themes = array();
// Loads theme data
$all_themes = wp_get_themes();
// Loads theme names into themes array
foreach ($all_themes as $theme) {
$themes[] = $theme->get('Name');
}
// Prints the theme names
print_r( $themes );
```
Which will output
```
Array (
[0] => Anchor Blank
[1] => Swell - Anchor Hosting
[2] => Swell
)
```
Taking this one step future you can build an array with all of the theme data like so.
```
// Build new empty Array to store the themes
$themes = array();
// Loads theme data
$all_themes = wp_get_themes();
// Build theme data manually
foreach ($all_themes as $theme) {
$themes{ $theme->stylesheet } = array(
'Name' => $theme->get('Name'),
'Description' => $theme->get('Description'),
'Author' => $theme->get('Author'),
'AuthorURI' => $theme->get('AuthorURI'),
'Version' => $theme->get('Version'),
'Template' => $theme->get('Template'),
'Status' => $theme->get('Status'),
'Tags' => $theme->get('Tags'),
'TextDomain' => $theme->get('TextDomain'),
'DomainPath' => $theme->get('DomainPath')
);
}
// Prints the themes
print_r( $themes );
```

Am I correct in thinking that you would need a file per pag? For example they have the same category dropdown on the Blog and Woocommerce shop page but I cannot see any code relating to that.
The website is [www.punjaban.co.uk](http://www.punjaban.co.uk) Thank you. | So, when I looked at the .htaccess file it had the following:
```
<FilesMatch "\.(?i:php)$">
<IfModule !mod_authz_core.c>
Order allow,deny
Deny from all
</IfModule>
<IfModule mod_authz_core.c>
Require all denied
</IfModule>
</FilesMatch>
```
I removed that and the menu works correctly. This may open up risks to other files so I will post on the Linux page to clarify the correction. Thanks Gary for pointing me in the right direction. |

In this template I am showing records from custom table. | Template files are not the right place to add in functions like that. The template file isnt loaded until late in the hook/filter process. Your function should be in functions.php. This way it can be added in before your tempalte files load, and functions that are in use in them can be altered.
Often times `wp_title()` is used in the header.php so it possible you are using that, but form the code you show you are filtering functions you are not using. Except maybe in header.php, but its loaded and executed before this custom template file. You also do not show the use of `the_title()` so I can not tell how/when/where this would actually filter anything if the function was placed in the right location. |

Can I somehow create a relative link ? | First of all, you shouldn't call your own PHP file. You should use `admin-ajax` endpoint. [Documentation](https://codex.wordpress.org/AJAX_in_Plugins)
On admin side, you could use ajaxurl to get URL for AJAX calls. On front side you have to declare by yourself variable with url. This is written in documentation:
>
> **Note**: Unlike on the admin side, the ajaxurl javascript global does not get automatically defined for you, unless you have BuddyPress or another Ajax-reliant plugin installed. So instead of relying on a global javascript variable, declare a javascript namespace object with its own property, ajaxurl. You might also use wp\_localize\_script() to make the URL available to your script, and generate it using this expression: admin\_url( 'admin-ajax.php' )
>
>
>
This should resolve problem:
```
add_action( 'wp_head', 'front_ajaxurl' );
function front_ajaxurl() {
wp_register_script( 'admin_ajax_front', plugin_dir_url(__FILE__) . 'script.js' );
$translation_array = array(
'ajaxurl' => admin_url( 'admin-ajax.php' )
);
wp_localize_script( 'admin_ajax_front', 'front', $translation_array );
wp_enqueue_script( 'admin_ajax_font', false, array(), false, true ); // last param set to true will enqueue script on footer
}
```
And then in your JS file:
```
$.ajax({
url: front.ajaxurl,
...
})

] | I have one site that is built with `html`, `css` and `javascript` and has no CMS. It looks great and my client would like that site to have wordpress in the background so he can easily modify the content. So, I'm a little bit stuck here.
I know that there are plugins for importing well written html, and they work like charm. But, I never done this kind of migration. How can I transfer whole site to wordpress? Is there a way to make some automatic scraping of the whole site, and easy way to import js libraries so i can preserve all classes, div or span tags in html, styles in css etc? | WordPress has a perfect wrapper for HTML > Theme conversion: The theme itself. All information can be found [in the Codex page](https://codex.wordpress.org/Theme_Development).
It is enough to add a folder to your `wp-content/themes` directory (or whatever directory you registered in addition to that), and add the following files
1. `functions.php`
2. `style.css`
3. `index.php`
4. `header.php`
to your custom `themename` folder. Then use the [Plugins API](https://codex.wordpress.org/Plugin_API) to attach some callbacks into the execution flow of WordPress core. This is where you would define basic things like adding stylesheets or scripts. Example for your `functions.php`:
```
add_action( 'wp_enqueue_scripts', function() {
// Register Stylesheets and Scripts in here
// @link https://developer.wordpress.org/reference/functions/wp_enqueue_script/
} );
```
In your `header.php`, you add the opening calls for your HTML:
```
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<?php wp_head(); ?>
</head>
```
The `wp_head();` function calls all the actions and this is where you registered scripts and stylesheets will appear.
In you `index.php`, you will add your body markup:
```
<?php get_header(); ?>
<body <?php body_class(); ?>>
<!-- Markup from your HTML files -->
<?php get_footer(); ?>
</body>
```
The `get_footer();` function will call a `footer.php` file if you include one.
Finally you just need to add [Page templates](https://developer.wordpress.org/themes/template-files-section/page-template-files/page-templates/) that replace the original PHP files. Those do not really differ from the `index.php` above, except for one thing: The header comment. Let's assume you add a copy of your `index.php`, rename it to `about-us.php` and add the following as first line:
```
<?php /** Template Name: About Us */ ?>
```
Now, when you in the admin UI go and add a new page, you can select this new template, you will have a replacement file for some existing HTML file. You can even adjust the slug in the admin UI page edit screen.
All that should give you a good start to converting your HTML templates to a valid WordPress theme. You can later and depending on your contract go and make those templates dynamic bit by bit – for example by splitting out repeating sidebars, make menus adjustable, [change the title](https://codex.wordpress.org/Function_Reference/the_title) and [the content](https://developer.wordpress.org/reference/functions/the_content/). |

``` | WordPress already adds classes to the body for you to handle this, as long as your theme correctly uses the body\_class template tag.
On the 2nd page of Page, your body will have these additional classes: `paged`, `paged-2` & `page-paged-2`, so you can see that you can make changes to styles to suit:
```
body.page {
background: black;
color: white;
}
body.paged {
background: green;
color: red;
}
```
Core achieves this with this logic:
```
global $wp_query;
$page = $wp_query->get( 'page' );
if ( ! $page || $page < 2 )
$page = $wp_query->get( 'paged' );
if ( $page && $page > 1 && ! is_404() ) {
$classes[] = 'paged-' . $page;
if ( is_single() )
$classes[] = 'single-paged-' . $page;
elseif ( is_page() )
$classes[] = 'page-paged-' . $page;
elseif ( is_category() )
$classes[] = 'category-paged-' . $page;
elseif ( is_tag() )
$classes[] = 'tag-paged-' . $page;
elseif ( is_date() )
$classes[] = 'date-paged-' . $page;
elseif ( is_author() )
$classes[] = 'author-paged-' . $page;
elseif ( is_search() )
$classes[] = 'search-paged-' . $page;
elseif ( is_post_type_archive() )
$classes[] = 'post-type-paged-' . $page;
}
```

Is there something I'm missing?? | WordPress already adds classes to the body for you to handle this, as long as your theme correctly uses the body\_class template tag.
On the 2nd page of Page, your body will have these additional classes: `paged`, `paged-2` & `page-paged-2`, so you can see that you can make changes to styles to suit:
```
body.page {
background: black;
color: white;
}
body.paged {
background: green;
color: red;
}
```
Core achieves this with this logic:
```
global $wp_query;
$page = $wp_query->get( 'page' );
if ( ! $page || $page < 2 )
$page = $wp_query->get( 'paged' );
if ( $page && $page > 1 && ! is_404() ) {
$classes[] = 'paged-' . $page;
if ( is_single() )
$classes[] = 'single-paged-' . $page;
elseif ( is_page() )
$classes[] = 'page-paged-' . $page;
elseif ( is_category() )
$classes[] = 'category-paged-' . $page;
elseif ( is_tag() )
$classes[] = 'tag-paged-' . $page;
elseif ( is_date() )
$classes[] = 'date-paged-' . $page;
elseif ( is_author() )

elseif ( is_search() )
$classes[] = 'search-paged-' . $page;
elseif ( is_post_type_archive() )

] | I would like to be able add the same custom colours to the swatches at bottom of colour picker panels that appear in the WYSIWYG editors across the site, to make it easier for clients to keep consistent in their styling.
The swatches I refer to are the bottom row in the screenshot.
I would like to do this without installing a plug-in, ideally.
[](https://i.stack.imgur.com/JeC7j.png) | Click on the `Custom...` text and the color picker will pop up. Pick the color of your choice and press `OK`. Chosen color will appear as a custom swatch for later use.
**Note!** The solution above is not a solution. See comments and edit below.
**Edit:**
Here is a function which replaces the entire default palette with custom swatches.
Note, there are 7 colors in the list instead 8. That's because there should be also the *multiplication X* (✕) at the end of the color list which removes any color applied to the text. So, when adding one more row there should be 15 colors, not 16.
```
function my_mce4_options($init) {
$custom_colours = '
"3366FF", "Color 1 name",
"CCFFCC", "Color 2 name",
"FFFF00", "Color 3 name",
"99CC00", "Color 4 name",
"FF0000", "Color 5 name",
"FF99CC", "Color 6 name",
"CCFFFF", "Color 7 name"
';
// build colour grid default+custom colors
$init['textcolor_map'] = '['.$custom_colours.']';
// change the number of rows in the grid if the number of colors changes
// 8 swatches per row
$init['textcolor_rows'] = 1;
return $init;
}
add_filter('tiny_mce_before_init', 'my_mce4_options');
```
Also, you can build you own swatch grid depending on the color number and UI requrements:
```
$init['textcolor_rows'] = 4;
$init['textcolor_cols'] = 2;
```

Hi,
I need help with my loop. What is does is split posts into two columns.
```
<?php $row_start = 1; while ( $query->have_posts() ) : $query->the_post(); ?>
<?php if ( in_array( get_the_ID(), $duplicates ) ) continue; ?>
<?php if( $row_start % 2 != 0) {// odd ?>
<div class="post">
left - <?php the_title();?><br>
</div>
<?php } ;?>
<?php if( $row_start % 2 == 0) {// even ?>
<div class="post">
right - <?php the_title();?><br>
</div>
<?php } ;?>
<?php ++$row_start; endwhile; wp_reset_postdata(); endif; ?>
```
It outputs the loop as the following:
```
<div class="left">post</div>
<div class="left">post</div>
<div class="right">post</div>
<div class="left">post</div>
<div class="right">post</div>
<div class="left">post</div>
<div class="right">post</div>
```
What I would to do is to wrap all posts in a div, like the following:
```
<div class="left">
post
post
post
</div>
<div class="right">
post
post
post
</div>
```
Thanks | You could always try to create 2 arrays of titles, say $left and $right, $odd and $even, or $tom and $jerry, and fill them with the titles during your loop, and print them after the loop has ended like so:
Create array
```
$left = $right = array();
```
Then unleash your loop [edited the below to reflect the comments]
```
<?php // The loop
if ( $query->have_posts() ) : $row_start = 1;
while ( $query->have_posts() ) : $query->the_post();
if ( in_array( get_the_ID(), $duplicates ) ) continue;
if( $row_start % 2 != 0) {
// odd: add result to $left
// $left[] = get_the_title();
$left[] = $post->id;
} else {
// even: add it to $right
//$right[] = get_the_title();
$right[] = $post->id;
}
++$row_start; endwhile; wp_reset_postdata();
// now loop has ended and we have 2 full arrays
// that we can print each in it's div
print "<div class=\"left\">";
foreach($left as $postID) {
$postData = get_post( $postID );
print $postData->post_title;
print $postData->post_content;
// etc... you can also get thumbnails using the post ID:
print get_the_post_thumbnail($postID, 'thumbnail');
}
print "</div>";
// next column
print "<div class=\"right\">";
foreach($right as $postID) {
// ... just like the above...
}
print "</div>";
endif;
?>
```
I've not yet tested this but it should work (or some close variation of it). I personally would output the list of posts in unordered lists (`<ul class="right or left">`) and put each title in an `<li>`.
Good luck :) |

Endgoal: I need that comment ID to use in an AJAX request - to fetch data (such as the comment thread depth) so that I can display custom data in the front end. | Here are few ideas:
* It's possible to inject custom HTML or data attributes via the [`comment_reply_link`](https://developer.wordpress.org/reference/functions/comment_reply_link/) filter, but I think it would be better to keep it unobtrusive.
* One could try to get the comment parent value from the reply comment form:
```
<input type='hidden' name='comment_parent' id='comment_parent' value='0' />
```
after it has been updated with the corresponding value.
* Another approach would be to scan for IDs in the HTML of the comments list:
Generated by the `Walker_Comment::html5_comment()`:
```
<li id="comment-34" class="comment even thread-even depth-1">
<article id="div-comment-34" class="comment-body">
... cut...
```
Generated by the `Walker_Comment::comment()`:
```
<li class="comment even thread-even depth-1 parent" id="comment-34">
<div id="div-comment-34" class="comment-body">
... cut...
```
One could e.g. search for both cases, but it's possible for the user to override these with a custom output.
Also note the `depth` information here.
* One could try to parse the `onclick` attribute of the *replyto* link:
```
onclick='return addComment.moveForm( "div-comment-34", "34", "respond", "123" )'

Thanks in advance! | To provide an answer to your first question and for future reference to tackle the problem you described with the slug already being in use when you first uploaded an attachment to the same parent. The following code will get rid of this 'annoying' thing *(annoying in some use cases)*.
This code rewrites the slug of the attachment upon uploading to add a prefix (or suffix) to the slug. In that case you have less chance of getting in the way of page slugs in the future.
```
add_action('add_attachment', function($postId) {
// get the attachment post object
$attachment = get_post($postId);
// get the slug for the attachment
$slug = $attachment->post_name;
// update the post data of the attachment with an edited slug
wp_update_post(array(
'ID' => $postId,
'post_name' => 'media-'.$slug, //adds a prefix
//'post_name' => $slug.'-photo', //adds a suffix
));
});
```
I hope this will help anyone. |

But the previous function removes also this version. So the question is how to make the two work together? | You can check for the current *handle* before removing the version.
Here's an example (untested):
```
add_filter( 'style_loader_src', 'sdt_remove_ver_css_js', 9999, 2 );
add_filter( 'script_loader_src', 'sdt_remove_ver_css_js', 9999, 2 );
function sdt_remove_ver_css_js( $src, $handle )
{
$handles_with_version = [ 'style' ]; // <-- Adjust to your needs!
if ( strpos( $src, 'ver=' ) && ! in_array( $handle, $handles_with_version, true ) )
$src = remove_query_arg( 'ver', $src );
return $src;
}

It gets converted to this by `do_shortcodes_in_html_tags()`:
```
[code]
$foo = <<<EOT
....
EOT;

```
Therefore, the shortcode doesn't run. Is there a way to make this shortcode work correctly? | A workaround might be:
```
[code]
$foo = <<<EOT
....
EOT;
[/code]
```
where we change `<<<` to `<<<`. We could do this automatically before `do_shortcode` filters the content and then replace it again afterwards.
I tested this version:
```
[code]
$foo = <<<EOT
....
EOT;<!---->
[/code]
```
and it seems to parse the shortocde's content correctly. But then we would need to remove the extra `<!---->` part, after `do_shortcode` has filtered the content. *This approach, with the HTML comment, would display the correct HTML source, but the rendering would be problematic, except within a `<textarea>`.*
**Peeking into the `/wp-includes/shortcodes.php` file**
The problem using an unclosed HTML tag, within the shortcode's content, seems to be that the `do_shortcodes_in_html_tags()` parser thinks `[/code]` is a part of it.
[This part](https://github.com/WordPress/WordPress/blob/ba12f4e95fec5e132868c21c5944a246841da9f3/wp-includes/shortcodes.php#L386-L387) of `do_shortcodes_in_html_tags()` seems to influense this behavior:
```
// Looks like we found some crazy unfiltered HTML. Skipping it for sanity.
$element = strtr( $element, $trans );
```
where `[/code]` is replaced to `[/code]`.
This happens just before the shortcode regex-replacements.
We would see `[/code]` from the output of `the_content()`, if [this part](https://github.com/WordPress/WordPress/blob/ba12f4e95fec5e132868c21c5944a246841da9f3/wp-includes/shortcodes.php#L226):
```
$content = unescape_invalid_shortcodes( $content );
```
wouldn't run at the end of the `do_shortcode()` function.
So it's like we didn't close the shortcode.
**HTML Encoding The Code Blocks**
We could HTML encode the content of the code blocks with:
```
add_filter( 'the_content', function( $content )
{
if( has_shortcode( $content, 'code' ) )
$content = preg_replace_callback(
'#\[code\](.*?)\[/code\]#s',
'wpse_code_filter',
$content
);
return $content;
}, 1 );
```
where our custom callback is defined as:
```
function wpse_code_filter( $matches )
{
return esc_html( $matches[0] );
}
```
Note that there are still things to be sorted out like
* content filters within the core, e.g. the `wpautop` filter,
* content filters from 3rd party plugins
* shortcodes inside the codeblock,
* etc.
It's informative to look at plugins like [`SyntaxHighligther Evolved`](https://wordpress.org/plugins/syntaxhighlighter/) to see the what kind of workarounds would be needed. (I'm not related to that plugin).
**Alternatives**
Another approach is to move the code outside of the content editor and store it in e.g.
* custom fields,
* custom tables
* custom post type (e.g. stored as excerpts).
For the latter case, this kind of shortcode comes to mind (PHP 7+):
```
add_shortcode( 'codeblock', function( Array $atts, String $content )
{
// Setup default attributes
$atts = shortcode_atts( [ 'id' => 0 ], $atts, 'codeblock_shortcode' );
// We only want to target the 'codeblock' post type
if( empty( $atts['id'] ) || 'codeblock' !== get_post_type( $atts['id'] ) )
return $content;
// Pre wrapped and HTML escaped post-excerpt from the 'codeblock' post type
return sprintf(
'<pre>%s</pre>',
esc_html(
get_post_field(
'post_excerpt',
$atts['id'],
'raw'
)
)
);
} );
```
*This might need further testing and adjustments!*
Then we could refer to each codeblock with
```
[codeblock id="123"]
```
in the content editor. |

(the redirect code is within `edit.php`) | Background
----------
The infamous "**Headers already sent**" error rears it's ugly head in circumstances where something attempts to modify the HTTP headers for the server's response *after* they have already been dispatched to the browser - that is to say, when the server should only be generating the *body* of the response.
This often happens in one of two ways:
* Code prints things too early before WordPress has finished composing headers - this pushes the HTTP response to the browser and forces the HTTP headers to be dispatched in the process. Any attempts by WordPress or third-party code that would normally properly modify the headers will subsequently produce the error.
* Code attempts to alter HTTP headers too late after WordPress has already sent them and begun to render HTML.
---
Problem & Solution Overview
---------------------------
This instance, the problem is the latter. This is because the `wp_safe_redirect()` function works by setting a `300`-range HTTP status header. Since the callback function arguments for `add_menu_page()` and `add_submenu_page()` are used to print custom markup after the dashboard sidebar and floating toolbar have already been generated, the callbacks are too late in WordPress's execution to use the `wp_safe_redirect()` function. As discussed in the comments, the solution is to move the `$wpdb->update()` and `wp_safe_redirect()` calls outside of your `views/edit.php` view template and "hook" them to an action that occurs before the HTTP headers are sent (before any HTML is sent to the browser).
---
Solving the Problem
-------------------
Looking at [the action reference for the typical admin-page request](https://codex.wordpress.org/Plugin_API/Action_Reference#Actions_Run_During_an_Admin_Page_Request), it's reasonable to assume that the `'send_headers'` action is the absolute latest that HTTP headers can be reliably modified. So your desired outcome could be achieved by attaching a function to that action or one before it containing your redirect logic - but you'd need to manually check which admin page is being displayed to ensure that you only process the `$wpdb->update()` and subsequent redirect for your `views/edit.php` template.
Conveniently, WordPress provides a shortcut for this contextual functionality with [the `'load-{page hook}'` action](https://codex.wordpress.org/Plugin_API/Action_Reference/load-(page)), which is dynamically triggered for each admin page loaded. While your call to `add_submenu_page()` will return the `{page hook}` value needed to hook an action for execution when your custom templates load, page hooks can be inferred in the format `{parent page slug}_page_{child page slug}`. Taking the values from your code, then, we end up with the `'load-bv_before_afters_main_page_bv_before_afters_edit'` action, which will only execute while loading your `views/edit.php` template.
The final issue becomes the matter of passing along whether or not `$wpdb->update()` produced an error to your `views/edit.php` template to determine whether or not to display the error message. This could be done using global variables or a custom action, however a better solution is to attach a function that will print your error to the `'admin_notices'` action which exists for exactly this reason. `'admin_notices'` will trigger right before WordPress renders your custom view template, ensuring that your error message ends up on the top of the page.
>
> **Note**
>
>
> The `$wpdb->update()` method returns the number of rows updated or `false` if an error is encountered - this means that a successful update query can change no rows and return `0`, which your `if()` conditional will lazily evaluate as `false` and display your error message. For this reason, if you wish to only display your error when the call actually fails, you should compare `$wpdb->update()`'s return value against `false` using the identity comparison operator `!==`.
>

---
Implementation
--------------
Combining all of the above, one solution might look as follows. Here I've used an extra array to hold the page slugs for your admin pages for the sake of easy reference, ensuring no typo-related issues and making the slugs easier to change, if necessary.
The entire portion of the `views/edit.php` file that you originally posted would now reside in the action hook, as well as any other business logic used to process the edit form.

Thank you! | `the_title()` is a template tag which relies on global state. Specifically `$post` global variable, holding current post instance.
While you *query* a set of posts, you never set up that global state for template tag to use.
Though in case you started with `get_posts()` it might be more convenient to leave global state alone altogether and just use `get_the_title()`, which can retrieve title of specific post on demand. |

233,780 | <p>I am trying to figure out to fire a hook for a custom post type called "bananas" when a new bananas post is published.</p>
<p>Requirements:</p>
<ul>
<li>Can't use $_POST </li>
<li>Need to be able to get post statuses so I can prevent code from running again later and check if its already published</li>
<li>Need to be able to get_post_meta</li>
</ul>
<p>The action hook is working perfectly. The only issue is that NEW post can't seem to get_post_meta. If you go from pending to publish or vice versa getting the meta works. But getting the meta on new post does not work and returns an empty result.</p>
<p>Heres an example of what I am trying to do.</p>
<pre><code>class bananas {
public function __construct() {
add_action( 'transition_post_status', array( $this, 'email_bananas_published' ), 10, 3 );
}
public function email_bananas_published( $new_status, $old_status, $post ) {
if ( $post->post_type === 'bananas' && $new_status !== $old_status ) {
$email = get_post_meta( $post->ID, '_bananas_email', true );
error_log( $email );
}
}
}
</code></pre>
<p>I have been stuck on this for a while and any help is much appreciated.</p>

Requirements:
* Can't use $\_POST
* Need to be able to get post statuses so I can prevent code from running again later and check if its already published
* Need to be able to get\_post\_meta
The action hook is working perfectly. The only issue is that NEW post can't seem to get\_post\_meta. If you go from pending to publish or vice versa getting the meta works. But getting the meta on new post does not work and returns an empty result.
Heres an example of what I am trying to do.
```
class bananas {
public function __construct() {
add_action( 'transition_post_status', array( $this, 'email_bananas_published' ), 10, 3 );

$email = get_post_meta( $post->ID, '_bananas_email', true );
error_log( $email );
}
}
}
```
I have been stuck on this for a while and any help is much appreciated. | The following worked for me. I hooked my meta saving and retrieving to the same action (post\_transition\_status), but with different priorities.
```
//Save Your Custom Meta Meta, but hook it to transition_post_status instead of save_post, with a priority of 1
function save_yourpost_meta(){
global $post;
if($post -> post_type == 'your_post_type') {
update_post_meta($post->ID, "your_meta_key", $_POST["your_meta_key"]);
}
}
add_action('transition_post_status', 'save_yourpost_meta',1,1);
//Then retrieve your custom meta only when the post is saved for the first time, not on updates. Hooked to the same action, with a lower priority of 100
function get_meta_on_publish($new_status, $old_status, $post) {
if('publish' == $new_status && 'publish' !== $old_status && $post->post_type == 'your_post_type') {
//Get your meta info
global $post;
$postID = $post->ID;
$custom = get_post_custom($postID);
//You have your custom now, have fun.
}
}
add_action('transition_post_status', 'get_meta_on_publish',100,3);
```

First, the PHP:
```
<div class="entry-meta">
<span class="term-links">
<?php foreach ( get_the_terms( $post->ID, 'region') as $term ) : ?>
<a href="<?php echo esc_url( get_term_link( $term->term_id ) ) ?>">Region: <span class="<?php echo $term->slug ?>"><?php echo $term->name ?></span></a>
<?php endforeach; ?>
</span>
</div>
```
Next, the CSS:
```
.term-links .usa {
display: inline-block;
width: 16px;
height: 11px;
background: url('http://i.stack.imgur.com/B2K4X.gif');
text-indent: 100%;
white-space: nowrap;
overflow: hidden;
}
```
Just repeat the CSS for each region, changing the background URL. |

My code:<http://pastebin.com/bvXcXhCQ> | Like @LupuAndrei said, we lack of details, especially the code where you call you form from.
But I suspect, again like @LupuAndrei said, you might not be calling the `settings_fields`, `do_settings_fields` or `do_settings_sections` correctly.
On the function where you build your form, try something like this
```
<form method="post" action="options.php">
<table class="form-table">
<?php
settings_fields( 'animated-settings-group' ); // This will output the nonce, action, and option_page fields for a settings page.
do_settings_sections( 'hoogleyboogley_animated' ); // This prints out the actual sections containing the settings fields for the page in parameter

I think you are misunderstanding what is happening here. XML plugins for WP would not go and create arbitrary HTML sitemap. That's just not what they are meant to do.
Since you have two different things in play here I tried to figure out what is what, using a basic check of looking at `body` tag:
* for `www.rissyroos.com/blog/` it is `<body class=" wordpress-index-index is-blog">`. This doesn't look like *normal* WordPress tag, but I suppose it does confirm that this is a WP–driven page.
* for `www.rissyroos.com/blog/sitemap_index.xml` it is `<body class=" amseohtmlsitemap-index-index">`. No mention of WordPress in sight.
My educated guess that however your WP is integrated into Magento site simply interferes with its full functionality, especially that falls under rewrite and custom URLs. |
235,039 | <p>I'm building a site with two separate CPTs <code>nominees</code> and <code>winners</code></p>

``` | `WP_Query` provides some useful properties. There are two of them which you could use:
* `$post_count` - The number of posts being displayed (if you not pass `posts_per_page` argument to WP\_Query construct it will return at most 5 posts)
* `$found_posts` - The total number of posts found matching the current query parameters (so if you have got 100 posts in database which will fit to the arguments then this property will return 100)
Here is sample of code:
```
$args = array( 'post_type' => 'testimonial' );
$loop = new WP_Query( $args );
$numposts = $loop->post_count;
if ($numposts == 1) {
// do X
} else if ($numposts > 1) {

} else {

Inside the `loop template` you use for listing blogs (like `index.php`) you need something like this
```
<a href="<?php the_permalink(); ?>/#respond"> <!-- The blog permalink with the anchor ID after -->
<i class="fa fa-comments-o"></i> Leave a Comment
</a>

```
<?php if ('open' == $post->comment_status) : ?>

Here's the custom post type registration:
```
if ( ! function_exists('rushhour_post_type_projects') ) :
// Add Portfolio Projects to WordPress
add_action( 'init', 'rushhour_post_type_projects', 0 );
// Register Portfolio Projects Custom Post Type
function rushhour_post_type_projects()
{
$labels = array(

'singular_name' => _x( 'Project', 'Post Type Singular Name', 'rushhour' ),
'menu_name' => __( 'Portfolio Projects', 'rushhour' ),

);
$rewrite = array(
'slug' => 'portfolio',
'with_front' => true,
'pages' => true,
'feeds' => true,
);
$args = array(
'label' => __( 'Project', 'rushhour' ),
'description' => __( 'Portfolio projects for Global VDC.', 'rushhour' ),
'labels' => $labels,
'supports' => array( 'title', 'editor', 'excerpt', 'thumbnail', 'revisions', ),

'hierarchical' => false,
'public' => true,

register_post_type( 'rushhour_projects', $args );
}
endif;
```
Then I've got a function for setting up the admin sub menu page.
```
if ( ! function_exists('rushhour_projects_admin_page') ) :
add_action( 'admin_menu' , 'rushhour_projects_admin_page' );
/**
* Generate sub menu page for settings
*
* @uses rushhour_projects_options_display()
*/
function rushhour_projects_admin_page()
{
add_submenu_page(
'edit.php?post_type=rushhour_projects',
__('Portfolio Projects Options', 'rushhour'),
__('Portfolio Options', 'rushhour'),
'manage_options',
'projects_archive',
'rushhour_projects_options_display');
}
endif;
```
So the above two items work without trouble.
The problem, I think, is somewhere in the functions below for registering and saving the settings:
```
if ( ! function_exists('rushhour_projects_options_display') ) :
/**
* Display the form on the Rush Hour Projects Settings sub menu page.
*
* Used by 'rushhour_projects_admin_page'.

function rushhour_projects_options_display()
{

echo '<div class="wrap">';
settings_errors();
echo '<form method="post" action="">';
var_dump( get_option('rushhour_projects_archive') );
settings_fields( 'edit.php?post_type=rushhour_projects&page=projects_archive' );
do_settings_sections( 'edit.php?post_type=rushhour_projects&page=projects_archive' );
submit_button();
echo '</form></div><!-- .wrap -->';
}
endif;
add_action( 'admin_init', 'rushhour_projects_settings' );
/**

*/
function rushhour_projects_settings()
{
if ( false == get_option( 'rushhour_projects_archive' ) )
add_option( 'rushhour_projects_archive' );
add_settings_section(
'projects_archive_header', // Section $id
__('Portfolio Project Archive Page Settings', 'rushhour'),
'rushhour_project_settings_section_title', // Callback
'edit.php?post_type=rushhour_projects&page=projects_archive' // Settings Page Slug
);

'header_text', // Field $id

'edit.php?post_type=rushhour_projects&page=projects_archive', // Settings Page Slug

array('Text to display in the archive header.')
);
register_setting(
'edit.php?post_type=rushhour_projects&page=projects_archive', // $option_group
'rushhour_projects_archive', // $option_name
'rushhour_projects_archive_save_options'
);
}
/**

*

*

*/
function rushhour_project_settings_section_title( $args ) {
// printf( '<h2>%s</h2>', apply_filters( 'the_title', $args['title'] ) );
}
/**
* Settings fields callbacks.
*/
function projects_archive_header_text_callback($args)
{
$options = get_option('rushhour_projects_archive');
printf( '<input class="widefat" id="header_text" name="rushhour_projects_archive[header_text]" type="textarea" value="%1$s" />',
$options );
}
/**

*/
function rushhour_projects_archive_save_options()
{
if ( isset( $_POST['rushhour_projects_archive[header_text]'] ) )
{
update_option( 'rushhour_projects_archive', $_POST['rushhour_projects_archive[header_text]'] );
}
}
``` | Ok, so I got annoyed with it not working and decided to just rewrite it. I'm not *sure* what the solution was, but I suspect two things: the wrong endpoint for the form (should be *options.php*) and the wrong `$option_group` and `$option_name` (they were probably not matched correctly).
For posterity, I'll leave my rewrite here and hopefully it helps others. A few differences between this and the previous version.
1. This is now in it's own file so you won't see the custom post type registered.
2. I used an object for the page per [example 2 from the WordPress codex](https://codex.wordpress.org/Creating_Options_Pages#Example_.232).
3. I added a second option for a media uploader using [this tutorial](http://jeroensormani.com/how-to-include-the-wordpress-media-selector-in-your-plugin/), which I updated to use [`wp_localize_script()`](https://developer.wordpress.org/reference/functions/wp_localize_script/) to inject a JSON object to get some PHP data.

Thanks in advance | You could do this without having to code anything special. Enter your first piece of text into the Excerpt field in the admin edit screen for the post. Enter only the remaining text into the visual editor.
That way you can have the excerpt text on the site's front page and the "rest" of the text after the thumbnail on the post's single page. |

Any ideas? | Today i got exactly the same behaviour when adding a custom post type. I also noticed some admin post search tools stopped working. My debug\_log showed exactly the same notice.
The problem turned out to be some text before the `<?php` opening tag (top file) were I register the CPT.
Example
```
some text here<?php
/**
* @class My_Cpt_Class
*/
.......
```
The CPT does get registered correctly. I can add posts etc. But a few default post actions (from other plugins aswell) stop working for ALL post types. I have no idea why this happens with this error. |
235,135 | <p>So on this Custom Post Type list page there is a list of Properties.</p>
<p>I have a custom search feature where they can search for Properties with certain Taxonomy Terms - but they can also search for Multiple Taxonomy Terms.</p>

<p>Now because these two Features are selected it should only return one Property because there is only one Property with <code>term_one</code> <code>AND</code> <code>term_two</code> together</p>

I have a custom search feature where they can search for Properties with certain Taxonomy Terms - but they can also search for Multiple Taxonomy Terms.
**Question**:
If someone selects 2 terms then the only Properties that should display in the list are Properties with `term_one` `AND` `term_two`

Now because these two Features are selected it should only return one Property because there is only one Property with `term_one` `AND` `term_two` together
However I don't get this result instead I get 4 Properties because there are 4 Properties. 3 with `term_one` and 1 with `term_two`.
What I want to happen is for 1 Property to be returned because there is only one Property with `term_once` `AND` `term_two` together.

'field' => 'slug',
'terms' => $tmp_required,
'operator' => 'AND',
),
);
}
}
```
**Edit #2**:
So here is the `var_dump` to the Query:
```
array(3) { ["post_type"]=> string(10) "properties" ["paged"]=> int(1) ["tax_query"]=> array(4) { ["taxonomy"]=> string(8) "features" ["field"]=> string(4) "slug" ["terms"]=> array(2) { [0]=> string(19) "accredited-landlord" [1]=> string(14) "cellarbasement" } ["operator"]=> string(3) "AND" } }
```
And here is the `var_dump` to the terms:
```
array(2) { [0]=> string(19) "accredited-landlord" [1]=> string(14) "cellarbasement" }
``` | **Query Arguments:**
If `$input_terms` is the input array of term slugs, then you should be able to use (if I understand the question correctly):
```
$property = [
'post_type' => 'properties',
'paged' => $paged,
'tax_query' => [
[
'taxonomy' => 'features',
'field' => 'slug',
'terms' => $input_terms,
'operator' => 'AND',
]
],
];
```
where we added a missing array in the tax query.
**Validation:**
We should **validate** the input terms first.
Here are some examples:
* Check the maximum number of allowed terms:
```
$valid_input_terms_max_count = count( $input_terms ) <= 4;
```
* Check the minimum number of allowed terms:
```
$valid_input_terms_min_count = count( $input_terms ) >= 1;
```
* Check if they input terms slugs exists (assumes non-empty input array):
```
$valid_input_terms_slugs = array_reduce(
(array) $input_terms,
function( $carry, $item ) {
return $carry && null !== term_exists( $item, 'features' );
},
true
);
```
where we collect [`term_exists()`](https://developer.wordpress.org/reference/functions/term_exists/) for all the terms into a single boolean value.
* We could also match the input slugs against a predefined array of slugs
**Generated SQL:**
Here's a generated SQL query for two existing term slugs in `$input_terms`:
```
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
FROM wp_posts
WHERE 1=1 AND (
(
SELECT COUNT(1)
FROM wp_term_relationships
WHERE term_taxonomy_id IN (160,161)
AND object_id = wp_posts.ID
) = 2
)
AND wp_posts.post_type = 'properties'
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private')
GROUP BY wp_posts.ID
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10
```
Hope you can adjust this to your needs. |

] | I want to add thumbnail to WordPress default recent posts widget, and I want to do it using any available filter.
Is there any filter know to this subject/topic | Here's one way to do it through the `the_title` filter. We can limit the scope to the *Recent Posts* widget, by initialize it within the `widget_posts_args` filter and then remove it again after the loop.
```
/**
* Recent Posts Widget: Append Thumbs
*/
add_filter( 'widget_posts_args', function( array $args )
{
add_filter( 'the_title', 'wpse_prepend_thumbnail', 10, 2 );
add_action( 'loop_end', 'wpse_clean_up' );
return $args;
} );
```
where we define
```
function wpse_prepend_thumbnail( $title, $post_id )
{
static $instance = 0;
// Append thumbnail every second time (odd)
if( 1 === $instance++ % 2 && has_post_thumbnail( $post_id ) )
$title = get_the_post_thumbnail( $post_id ) . $title;
return $title;
}
```
and
```
function wpse_clean_up( \WP_Query $q )
{
remove_filter( current_filter(), __FUNCTION__ );
remove_filter( 'the_title', 'wpse_add_thumnail', 10 );
}
```
Note that because of this check in the `WP_Widget_Recent_Posts::widget()` method:
```
get_the_title() ? the_title() : the_ID()
```
the `the_title` filter is applied two times for each item. That's why we only apply the thumbnail appending for the odd cases.
Also note that this approach assumes non empty titles.
Otherwise it's more flexible to just create/extend a new widget to our needs instead. |

I'm using this outside of "the loop". | Another idea (which heavily depends on what you are viewing [single or archive] and also your taxonomy-structure) is to look for the term parent.
Maybe this can help you aswell ...
You were asking about "highest category in the hierarchy for a specific post".
Example:
A post is associated with **3 terms** of an taxonomy which are **hierachical**:
```
Parent Term
-First-Child Term
--Second-Child Term
```
You could get all the associated terms of this post:
```
$all_terms = get_the_terms( $post_id, $taxonomy );
```
And than find the term which has a **parent** of **0**:
```
foreach($all_terms as $term) {
if($term->parent == 0){
//here you have the data of the topmost parent, e.g. "Parent Term"
// get parent term ID
$parent_id = $term->term_id;
// get term obj from ID to get term name
$parent_obj = get_term_by( 'id', $parent_id, $taxonomy );
// show parent term name
echo $parent_obj->name; // "Parent Term"
// show parent term permalink URL
echo = get_term_link( $parent_id );
}
}
```
As you see, this will only work if the post has only one parent and than child-terms assiciated. For other setups this will not work! |

Thanks for the help in advance! | You can use the function [wp\_list\_pluck](https://codex.wordpress.org/Function_Reference/wp_list_pluck) to get the ID of the posts retrieved from the query.
Just move the query before the h2 element and get the posts ID's:
```
// Set a bool to know if at least one post has post thumbnail.
$has_thumb = false;
$first_query = new WP_Query('cat=1&author=' . $post->post_author . '&order=DESC&tag=Tattoo&posts_per_page=1000');
// Check if the query have posts.
if ( $first_query->have_posts() ) {
// Get the posts id's.
$ids = wp_list_pluck($first_query->posts, 'ID');
foreach( $ids as $id ) {
if ( has_post_thumbnail($id) ) {
$has_thumb = true;
break; // If at least we have a post thubmnail we don't need to continue.
}
}
}
```
Then you can check if there are thumbnails and show the h2 if so.
```
<?php if ( $has_thumb ) : ?>
<h2>Tattoo Work by <span style="text-transform: capitalize;"><?php the_author_meta('user_nicename'); ?></span>:</h2>

```
<?php do_action('post_footer'); ?>
```
[Based on some reading](https://developer.wordpress.org/reference/functions/do_action/), this appears to call a hook action. So, I went through all of the PHP files in the `Editor` and I don't find `post_footer` anywhere. I also noticed it call these hooks elsewhere, so it would be useful to know where these are stored. What files are these hook actions stored in?
What I searched for using is `add_action` in each file to discover the `post_footer` as one of the parameters, but never found anything for `post_footer` as an action. Where else would these action hooks be, if not in the php files? | Hooks/actions are better thought of as events.
When you run this code:
```
add_action( 'post_footer', 'toms_footer_stuff' );
```
You're saying that when the `post_footer` event happens, run the `toms_footer_stuff` function.
These functions take the form of:
```
add_action( name_of_action, php_callable );
```
A PHP callable is something that can be called represented as an object. It can be any of these:
```
add_action( 'post_footer', 'toms_footer_stuff' ); // a function
add_action( 'post_footer', array( 'toms_class', 'toms_footer_stuff' ); // a static method on a class
add_action( 'post_footer', array( $toms_class, 'toms_footer_stuff' ); // a method on an object
add_action( 'post_footer', function() { echo "hello world"; } ); // an anonymous function
add_action( 'post_footer', $toms_closure ); // a Closure
```
When you call `do_action('post_footer')`, you're saying that the `post_footer` event is happening, call all the things that have hooked into it. There's no `post_footer` function to call ( unless you define one yourself but that would just be a coincidence, it wouldn't run unless you called `add_action` ).
`post_footer` has more in common with a key in an array.
Filters are similar, except they take a value as their first function argument, and return it.
Internally they use the same system as actions, as such these 2 calls should do the same thing:
```
do_action( 'init' );
apply_filters( 'init', null ); // not recommended/tested
```
Actions are for doing work, filters are for adjusting or modifying data/content. If you do work in a filter, your site will slow down. Filters get called a lot more than actions and tend to happen multiple times ). Actions on the other hand tend to happen once at a specific time. |

] | I'm using a Custom Theme to re-design our website. However, I'm getting an issue where the Menu jumps around and shows all links, before quickly collapsing them under the parent options, in the menu.
Here is the staging site:
<http://volocommerce.staging.wpengine.com/>
However, this is the code I'm using:
```
<nav class="navbar navbar-default" role="navigation">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar bar-1"></span>
<span class="icon-bar bar-2"></span>
<span class="icon-bar bar-3"></span>
</button>
</div>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<div class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div id="" class="">
<?php
//$walker = new Menu_With_Description;
wp_nav_menu (array ('theme_location' => 'header_menu',
'container' => 'div',
'container_class' => '',
'container_id' => '',
'menu_class' => 'menu',
'menu_id' => '',
'echo' => true,
'fallback_cb' => 'wp_page_menu',
'before' => '',
'after' => '',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul class="nav navbar-nav top_items">%3$s</ul>',
'depth' => 0,
//'walker' => $walker,
)); ?>
</div>
</div>
</div>
</div>
</nav>
```
And here is the script for the mobile menu/scroll menu:
```
<script>
$(function(){
$('.navbar ul li:has(ul)').addClass('dropdown');
$('.navbar navbar-collapse ul:has(li)').addClass('dropdown-menu');
$('.navbar ul li ul:has(li)').addClass('dropdown-menu');
$('.navbar ul li ul li:has(div)').addClass('yamm-content');

$('.navbar .lang_drop ul li:has(ul)').removeClass('');
//yamm-fw
$('.dropdown:has(a)').addClass('dropdown-toggle');
$('.more_menu').addClass('yamm-fw');
});
$(window).scroll(function(e){
$el = $('.head_con');
if ($(this).scrollTop() > 150 ){
$('.head_con').addClass('head_con_scroll');
$('.logo_con').addClass('logo_con_scroll');
$('.menu-item').addClass('menu-item_scroll');
$('.head_phone_con').addClass('head_phone_con_scroll');

``` | Hooks/actions are better thought of as events.
When you run this code:
```
add_action( 'post_footer', 'toms_footer_stuff' );
```
You're saying that when the `post_footer` event happens, run the `toms_footer_stuff` function.
These functions take the form of:
```
add_action( name_of_action, php_callable );
```
A PHP callable is something that can be called represented as an object. It can be any of these:
```
add_action( 'post_footer', 'toms_footer_stuff' ); // a function
add_action( 'post_footer', array( 'toms_class', 'toms_footer_stuff' ); // a static method on a class
add_action( 'post_footer', array( $toms_class, 'toms_footer_stuff' ); // a method on an object
add_action( 'post_footer', function() { echo "hello world"; } ); // an anonymous function
add_action( 'post_footer', $toms_closure ); // a Closure
```
When you call `do_action('post_footer')`, you're saying that the `post_footer` event is happening, call all the things that have hooked into it. There's no `post_footer` function to call ( unless you define one yourself but that would just be a coincidence, it wouldn't run unless you called `add_action` ).
`post_footer` has more in common with a key in an array.
Filters are similar, except they take a value as their first function argument, and return it.
Internally they use the same system as actions, as such these 2 calls should do the same thing:
```
do_action( 'init' );
apply_filters( 'init', null ); // not recommended/tested
```
Actions are for doing work, filters are for adjusting or modifying data/content. If you do work in a filter, your site will slow down. Filters get called a lot more than actions and tend to happen multiple times ). Actions on the other hand tend to happen once at a specific time. |

Anyone an idea? | I'd steer clear on editing the `.htaccess` if you're just updating your website from HTTP to HTTPS. Try an alternative route:
First, revert your `.htaccess` back to the default settings:
```
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
```
Next, you need to ensures that all of the URLs for your website are up-to-date, try the following steps using the [Search Replace DB tool](https://interconnectit.com/products/search-and-replace-for-wordpress-databases/):
1. Go and download [Interconnect IT's Database Search & Replace Script here](https://github.com/interconnectit/Search-Replace-DB/archive/master.zip)
2. Unzip the file and drop the folder in your **localhost** where your WordPress is installed (the root) and rename the folder to **`replace`** ([screenshot](https://i.stack.imgur.com/J9Ga5.png))
3. Navigate to the new folder you created in your browser (ex: `http://web.site/replace`) and [you will see the search/replace tool](https://i.stack.imgur.com/pbED1.png)
4. It should be pretty self-explanatory up to this point: enter your HTTPS link in the **`search for…`** field and the new HTTPS link in the **`replace with…`** field
You can click the *dry run* button under *actions* to see what it will be replacing before you execute the script. Once you're done be sure to remove the `/replace/` folder.
### However...
If you still insist on having your HTTP redirect to HTTPS via the `.htaccess` add the following in between the `<IfModule mod_rewrite.c>` tag:
```
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [R,L]
```
It should look like the following:
```
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# Rewrite HTTP to HTTPS
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [R,L]
</IfModule>

And this is a problem because afterwards when the post is published under a real url disqus will not recognize the comments count. The only way is to manually change the discussion url. I've already contacted disqus and they say, "not a bug" if you do not want disqus to pick the preview url, don't load disqus on the preview page, the only way i know is to completely remove the comments form, so how would i go about this?

```
add_action( 'init', 'custom_format_permalinks', 1 );
function custom_format_permalinks() {
$taxonomy = 'post_format';
$post_format_rewrite = array( 'slug' => NULL, );
add_permastruct( $taxonomy, "%$taxonomy%", $post_format_rewrite );
}
```
Or simply:
```
add_filter('post_format_rewrite_base', 'post_format_base');
function post_format_base($slug) {return '/';}
```
These are the typical answers given elsewhere for this question. And they both get the job done, except that... pagination and feeds are no longer working.
Then I tried this route...
```
add_filter('post_format_rewrite_base', 'no_format_base_rewrite_rules');
function no_format_base_rewrite_rules($format_rewrite) {
$format_rewrite = array();
$formats = get_post_format_slugs();
foreach($formats as $format_nicename => $key) {
$format_rewrite['('.$format_nicename.')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?post_format=$matches[1]&feed=$matches[2]';
$format_rewrite['('.$format_nicename.')/?([0-9]{1,})/?$'] = 'index.php?post_format=$matches[1]&paged=$matches[2]';
$format_rewrite['('.$format_nicename.')/?$'] = 'index.php?post_format=$matches[1]';
}
return $format_rewrite;
}
```
This sort of approach is proven to work perfectly with categories, tags or authors, but for some reason it doesn't do the job this time. What could be wrong? | Excellent answer above, well worth the bounty. For the record, this is what it led to:
```
add_filter( 'post_format_rewrite_rules', 'no_format_base_rewrite_rules' );
function no_format_base_rewrite_rules( $format_rewrite ) {
$format_rewrite = array();
$formats = get_post_format_slugs();
foreach($formats as $format_nicename) {
$format_rewrite['(' . $format_nicename . ')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?post_format=$matches[1]&feed=$matches[2]';
$format_rewrite['(' . $format_nicename . ')/?([0-9]{1,})/?$'] = 'index.php?post_format=$matches[1]&paged=$matches[2]';
$format_rewrite['(' . $format_nicename . ')/?$'] = 'index.php?post_format=$matches[1]';
}
return $format_rewrite;
}

] | I have written a plugin in which you have a small chat icon in the bottom right corner, however I want the user to be able to choose an image as the icon from the `Media Library`. How can I do this with the Wordpress API? The image is a setting in the plugin (only changable by the admin) | You should use `wp.media` to use the WordPress Media Manager dialog.
First, you need to enqueue the scritps:
```
// As you are dealing with plugin settings,
// I assume you are in admin side
add_action( 'admin_enqueue_scripts', 'load_wp_media_files' );
function load_wp_media_files( $page ) {
// change to the $page where you want to enqueue the script
if( $page == 'options-general.php' ) {
// Enqueue WordPress media scripts
wp_enqueue_media();
// Enqueue custom script that will interact with wp.media
wp_enqueue_script( 'myprefix_script', plugins_url( '/js/myscript.js' , __FILE__ ), array('jquery'), '0.1' );
}
}
```
Your HTML could be something like this (note my code use attachment ID in the plugin setting instead of image url as you did in your answer, I think it is much better. For example, using ID allows you to get different images sizes when you need them):
```
$image_id = get_option( 'myprefix_image_id' );
if( intval( $image_id ) > 0 ) {
// Change with the image size you want to use
$image = wp_get_attachment_image( $image_id, 'medium', false, array( 'id' => 'myprefix-preview-image' ) );
} else {
// Some default image
$image = '<img id="myprefix-preview-image" src="https://some.default.image.jpg" />';
}
echo $image; ?>
<input type="hidden" name="myprefix_image_id" id="myprefix_image_id" value="<?php echo esc_attr( $image_id ); ?>" class="regular-text" />
<input type='button' class="button-primary" value="<?php esc_attr_e( 'Select a image', 'mytextdomain' ); ?>" id="myprefix_media_manager"/>
```
myscript.js
```
jQuery(document).ready( function($) {
jQuery('input#myprefix_media_manager').click(function(e) {
e.preventDefault();
var image_frame;
if(image_frame){
image_frame.open();
}
// Define image_frame as wp.media object
image_frame = wp.media({
title: 'Select Media',
multiple : false,
library : {
type : 'image',
}
});
image_frame.on('close',function() {
// On close, get selections and save to the hidden input
// plus other AJAX stuff to refresh the image preview
var selection = image_frame.state().get('selection');
var gallery_ids = new Array();
var my_index = 0;
selection.each(function(attachment) {
gallery_ids[my_index] = attachment['id'];
my_index++;
});
var ids = gallery_ids.join(",");
if(ids.length === 0) return true;//if closed withput selecting an image
jQuery('input#myprefix_image_id').val(ids);
Refresh_Image(ids);
});
image_frame.on('open',function() {
// On open, get the id from the hidden input
// and select the appropiate images in the media manager
var selection = image_frame.state().get('selection');
var ids = jQuery('input#myprefix_image_id').val().split(',');
ids.forEach(function(id) {
var attachment = wp.media.attachment(id);
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
});
});
image_frame.open();
});
});
// Ajax request to refresh the image preview
function Refresh_Image(the_id){
var data = {
action: 'myprefix_get_image',
id: the_id
};
jQuery.get(ajaxurl, data, function(response) {
if(response.success === true) {
jQuery('#myprefix-preview-image').replaceWith( response.data.image );
}
});
}
```
And the Ajax action to refresh the image preview:
```
// Ajax action to refresh the user image
add_action( 'wp_ajax_myprefix_get_image', 'myprefix_get_image' );
function myprefix_get_image() {
if(isset($_GET['id']) ){
$image = wp_get_attachment_image( filter_input( INPUT_GET, 'id', FILTER_VALIDATE_INT ), 'medium', false, array( 'id' => 'myprefix-preview-image' ) );
$data = array(
'image' => $image,
);
wp_send_json_success( $data );
} else {
wp_send_json_error();
}
}
```
PD: it is a quick sample written here based on [other answer](https://wordpress.stackexchange.com/questions/233199/get-attachment-id-of-author-meta-image-attachment-metadata/233212#233212).

return strnatcasecmp( $a_last_name, $b_last_name );
}
```
[`explode()`](http://php.net/explode) will convert your names into arrays; [`array_pop()`](http://php.net/array_pop) will give you the last item in those arrays, which is what you're looking for. Then you just do the comparison you were already doing to sort them.
Using an anonymous function
---------------------------
Per the PHP page on [`create_function()`](http://php.net/create_function), if you're using PHP 5.3 or newer, you should use an [anonymous function](https://secure.php.net/manual/en/functions.anonymous.php) (or "closure") instead of `create_function()`.
```
usort($users, function( $a, $b ) {
$a_last_name = array_pop( explode( ' ', $a->last_name ) );
$b_last_name = array_pop( explode( ' ', $b->last_name ) );
return strnatcasecmp( $a_last_name, $b_last_name );

235,442 | <p>I have written a simple author subscription plugin. Basically, it shows a subscribe button similar to YouTube. When a (logged in) user clicks on it, they subscribe to that author, and will get notified by their posts.</p>
<p>I'm using AJAX to make the button not refresh the page, and a data-attribute to send the author ID to my function, but I'm not sure if this approach causes any risks.</p>
<pre><code><button class="subscribe_button" data-author-id="352" data-action="subscribe">
</code></pre>
<p>Could someone theoretically change this data-attribute's value to cause an SQL injection or something? It seems that posting data through AJAX is very vulnerable to attacks, more so than if it were just a PHP file. Am I justified into thinking this? Are there any risks involved with my code below?</p>
<pre><code><script>
( function( $ ) {
var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>",
subscriptions_container = $('.subscriptions_container');
$(subscriptions_container).on('click', '.subscribe_button', function() {
// Disable button temporarily
$(this).unbind("click");
var thisButton = $(this);
// Define author_id and button action
var author_id = $(this).data( "author-id"),
action = $(this).data( "action") + '_callback';
// Data to be sent to function
var data = {
'action': action,
'security': '<?php echo $ajax_nonce; ?>',
'author_id': author_id
};
// Send data with AJAX
jQuery.post(ajaxurl, data, function(response) {
thisButton.closest('.subscriptions').replaceWith(response);
});
});
} )( jQuery );
</script>
</code></pre>
<p>And my PHP callback function:</p>
<pre><code>function subscribe_callback() {
check_ajax_referer( '*****', 'security' );
if ( is_user_logged_in() ) {
global $wpdb;
$table_name = $wpdb->prefix . "subscriptions";
// Check if author_id is posted and if it's a number
if ( isset($_POST['author_id']) && is_numeric($_POST['author_id']) ) {
$author_id = $_POST['author_id'];
$subscriber_id = get_current_user_id();
// check if author is not subscribing to himself, if not then add database query
if ( $author_id != $subscriber_id ) {
if ( $wpdb->insert(
$table_name,
array(

] | I have written a simple author subscription plugin. Basically, it shows a subscribe button similar to YouTube. When a (logged in) user clicks on it, they subscribe to that author, and will get notified by their posts.
I'm using AJAX to make the button not refresh the page, and a data-attribute to send the author ID to my function, but I'm not sure if this approach causes any risks.
```
<button class="subscribe_button" data-author-id="352" data-action="subscribe">
```
Could someone theoretically change this data-attribute's value to cause an SQL injection or something? It seems that posting data through AJAX is very vulnerable to attacks, more so than if it were just a PHP file. Am I justified into thinking this? Are there any risks involved with my code below?
```
<script>
( function( $ ) {
var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>",
subscriptions_container = $('.subscriptions_container');
$(subscriptions_container).on('click', '.subscribe_button', function() {
// Disable button temporarily
$(this).unbind("click");
var thisButton = $(this);
// Define author_id and button action
var author_id = $(this).data( "author-id"),
action = $(this).data( "action") + '_callback';
// Data to be sent to function
var data = {
'action': action,
'security': '<?php echo $ajax_nonce; ?>',
'author_id': author_id
};
// Send data with AJAX
jQuery.post(ajaxurl, data, function(response) {
thisButton.closest('.subscriptions').replaceWith(response);
});
});
} )( jQuery );
</script>
```
And my PHP callback function:
```
function subscribe_callback() {
check_ajax_referer( '*****', 'security' );
if ( is_user_logged_in() ) {
global $wpdb;
$table_name = $wpdb->prefix . "subscriptions";
// Check if author_id is posted and if it's a number
if ( isset($_POST['author_id']) && is_numeric($_POST['author_id']) ) {
$author_id = $_POST['author_id'];
$subscriber_id = get_current_user_id();
// check if author is not subscribing to himself, if not then add database query
if ( $author_id != $subscriber_id ) {
if ( $wpdb->insert(
$table_name,
array(
'subscriber_user_id' => $subscriber_id,
'author_user_id' => $author_id,
'email_notification' => 'yes',
'subscription_date' => current_time( 'mysql' )
),
array(
'%d',
'%d',
'%s',
'%s'
)
) !== FALSE ) {
// add subscriber to usermeta
$author_subscriber_count = get_user_meta($author_id, 'subscribers', true);
$author_subscriber_count++;
update_user_meta($author_id, 'subscribers', $author_subscriber_count);
echo subscribe_button($author_id);
}
}
}
}
wp_die();
} add_action( 'wp_ajax_subscribe_callback', 'subscribe_callback' );
``` | When dealing with submit forms, even if they are sent with AJAX, you must play by the ***[Never trust user's input](https://www.owasp.org/index.php/Don't_trust_user_input)*** rule.
Every `data-attribute` can be changed, edited via Inspector. Your only trusted validation should be on the server side, as you did with:
```
if ( isset($_POST['author_id']) || is_numeric($_POST['author_id']) )
```
Personally, I would inverse the logic and first check all the attributes before starting any action.
```
check_ajax_referer( '*****', 'security' );
if ( ! isset($_POST['author_id']) && ! is_numeric($_POST['author_id']) ) {
// tell the villain that this tower is watched
wp_send_json_error( 'Wrong author ID!' );
}
// now is safe to cache
$author_id = $_POST['author_id'];
```

If so, how can I do this the Wordpress way?
===========================================
This seems like a simple thing to do ( at least from a database perspective ) but I'm looking for the Wordpress way to get multiple post\_meta values from a bunch of CPTs. Example:
Every `Product` Custom Post Type has the following fields ( plus many more ) which holds discrete pieces of information:
* `_ns_research_document`
* `_ns_monograph_document`
* `_ns_profile_document`
Essentially, I want a list of ALL ***Research** Docs*, ***Monographs*** and ***Profile** Docs*. Currently this site has 72 `product` posts, but other sites this will be used on have over a thousand.
I assume there's a way to do this with wordpress methods that doesn't involve [at least] 73 calls ( one for all posts, and then `get_post_meta` inside the loop ).
The general solution I've found suggest a get\_post\_meta inside a foreach loop: <https://stackoverflow.com/questions/14699686/custom-post-type-loop-only-displays-first-post-meta-data>
But in this case, I really only want the `meta_values` in an array for a specific **CPT**.

**UPDATE**
Made use of [Output Buffering](http://php.net/manual/en/book.outcontrol.php) to expand shortcodes before we try to load the HTML in DOMDocument
Note that both solutions (before and after the edit) are working, so errors/warnings should come from elsewhere in your setup. |

It is giving an error like bellow,
```
Blocked loading mixed active content "http://www.example.com/wp-content/uploads/image.jpg"

How should I avoid that errors and load the images on that page.
I saw in a article simplest way to fix it by converting urls into relative urls.
eg:
```
http://www.example.com/wp-content/uploads/image.jpg -> //wp-content/uploads/image.jpg
```
Any idea how should I do that ? | simply used the `str_replace` function to convert the urls to `https`
```
$content = get_the_content();
$content = apply_filters( 'the_content', $content );
$content = str_replace( ']]>', ']]>', $content );
$content = str_replace("http://example.com/", "https://example.com/", $content);

235,563 | <p>I have to make a site where i have to assign posts to users.</p>
<p>Want i already did:</p>
<p>1: made new user roles with only 'read' enabled</p>
<p>But i can't seem to figure out how to assign a certain post to a specific user/user role.
So that when there logged in they will only see the post that is assigned to them, instead of seeing all the post and when they click it they get a message like: "Sorry, you have to be user*** to see this post."</p>
<p>Does anyone know how to do this?</p>
