Thanks | This is not working because `the_terms()` is echo-ing the output.
It would make more sense to trim down the lengthy term names, instead of doing it directly on the HTML output of `get_the_term_list()` that's used by `get_the_terms()`. That could give unvalid HTML, that could break the layout of your site.
Here's an example for the corresponding theme file:
```
// Add a filter
add_filter( 'get_the_terms', 'wpse248787_get_the_terms' );
// Display terms
the_terms( get_the_ID(), 'tapahtumat' );
// Remove the filter again
remove_filter( 'get_the_terms', 'wpse248787_get_the_terms' );
```
where you have defined:
```
function wpse248787_get_the_terms( $terms )
{
$len = 10; // <-- Adjust to your needs!
// Limit term names if needed
foreach( $terms as $term )
{
if( $len > 0 && $len < mb_strlen( $term->name ) )
$term->name = mb_substr( $term->name, 0, $len - 1, 'UTF8' ) . '…';
}
return $terms;
}
```
in the `functions.php` file in the current theme directory. You might also need to addjust the encoding argument or use e.g. `get_option( 'blog_charset' )`. |

The site isn't ready to replace the live WP site yet (mysite.com) but I need to map one of the pages to the old domain and make it public. Since all the work (template,database,etc) is on the subdomain, I can't just import the page to the old domain, so I seemingly need to use <code>mod_rewrite</code>, which is way beyond my skill level.
Also, since its two different WP Installations (not multisite), would I use the domain <code>.htaccess</code> file or the subdomain <code>.htaccess</code> file?</p>

**Solved**
Manually updating Wordpress solved the problem. | **Manually updating Wordpress fixes this issue.**
***Upgrading WordPress Core Manually (How To)*** [WordFence Reference](https://www.wordfence.com/learn/how-to-manually-upgrade-wordpress-themes-and-plugins/)
* First create a full backup of your website. This is very important in
case you make a mistake.
* Download the newest WordPress ZIP file from wordpress.org. Unzip the
file into a directory on your local machine or in a separate
directory on your website.
* Deactivate all of the plugins on your WordPress site.
* Go to your website root directory and delete your ‘wp-includes’ and
‘wp-admin’ directories. You can do this via sFTP or via SSH.
* Upload (or copy over) the new wp-includes and wp-admin directories
from the new version of WordPress you unzipped to your website root
directory to replace the directories you just deleted.
* Don’t delete your wp-content directory or any of the files in that
directory. Copy over the files from the wp-content directory in the
new version of WordPress to your existing wp-content directory. You
will overwrite any existing files with the same name. All of your
other files in wp-content will remain in place.
* Copy all files from the root (‘/’) directory of the new version of
WordPress that you unzipped into your website root directory (or the
root directory of your WordPress installation). You will overwrite
any existing files and new files will also be copied across. Your
wp-config.php file will not be affected because WordPress is never
distributed with a wp-config.php file.
* Examine the wp-config-sample.php which is distributed with WordPress
to see if any new settings have been added that you may want to use
or modify.
* If you are upgrading manually after a failed auto-update, remove the
.maintenance file from your WordPress root directory. This will
remove the ‘failed update’ message from your site.
* Visit your main WordPress admin page at /wp-admin/ where you may be
asked to sign-in again. You may also have to upgrade your database
and will be prompted if this is needed. If you can’t sign-in, try
clearing your cookies. Re-enable your plugins which you disabled
earlier.
* Clear your browser cache to ensure you can see all changes. If you
are using a front-end cache like ‘varnish’ you should also clear that
to ensure that your customers can see the newest changes on your
site.
* Your upgrade is now complete and you should be running the newest
version of WordPress. |

``` | You can create your custom pagination using `paginate_link()` function and add custom query string after current url.
To add argument to the links of paginations you can pass them as array argument inside the 'add\_args'
```
if ( is_home() || is_archive() || is_search() ) :
echo paginate_links(array(
'base' => preg_replace('/\?.*/', '/', get_pagenum_link(1)) . '%_%',
'current' => max(1, get_query_var('paged')),
'format' => 'page/%#%',
'total' => $wp_query->max_num_pages,

'add_args' => array(
'sort_by_type' => ( !empty($_GET['sort_by_type']) ) ? $_GET['sort_by_type'] : 'vote'
)
));
endif;
```
Replace your pagination code with this above code.
It will print all string with custom query string.
`http://example.com/page/2/?sort_by_type=vote`

Is there a way to do it with filters? I tried to put it in the\_content but the date displays below the title. | Base on @Tunji answer.
You can add some conditions to the function to detect home-page, feeds...
```
function display_extra_title( $title, $id = null ) {
$date = the_date('', '', '', false);
if(is_home()){
$title = get_bloginfo( 'name' );
return $date . $title;
}
else{
return $date . $title;
}
}
add_filter( 'the_title', 'display_extra_title', 10, 2 );
```
In order to properly return `the_date` and not echoing it, you must set the last parameter to false. See more details [here](https://codex.wordpress.org/Function_Reference/the_date)
If you don't want to display the date in the menu widget... You can surround `$date` in a span and add css to not display it when it's the menu, sidebar...
```
$title = '<span class="title_date">'.$date.'</span> '.$title;
```
In the css (adjust and add all what you need:
```
.sidebar .title_date{ display:none;}

Can anybody, please, help me? What am I missing? | 4.7 has it enabled by default. The easy way to check if it is working is just to visit the example.com/wp-json url, and you should get a list of registered end points there
There is no official option to disable it as (at least there was a talk about it not sure if it got in the release), some core functionality depends on it.
The most obvious things to check for if it is not working is your htaccess rules, and do you have a wp-json directory
Also, if `/wp-json/wp/v2/posts` type URLs don't work for you, but `/?rest_route=/wp-json/wp/v2/posts` does, it means you need to enable pretty permalinks in the settings (suggested by Giles Butler in comments below). |

WP already does this out of the box thanks to the include\_children parameter of tax\_query which is true by default.
So you do not need to tell it the sub-terms, just do something like this:
```
/wp/v2/posts?categories=1
```

Why the order doesn't work correctly for all the post title? | Try adding `'suppress_filters' => true` to your query args. Maybe you have a plugin that modifies the queries.
You could also check if the posts out of order (the first one) is a sticky post. Sticky posts by default skip the order queue.
You can disable this by adding `'ignore_sticky_posts' => true` to your query args. |

] | I have an issue with custom widgets and WordPress Coding Standards. When you create a custom widget, your class should have a "widget" method that will display the widget. Something like:
```
<?php
public function widget( $args, $instance ) {
echo $args['before_widget'];
?> <span><?php echo esc_html( 'Great widget', 'text-domain' ); ?></span> <?php
echo $args['after_widget'];
}
?>
```
While this is perfectly functional, this will not pass PHP code sniffer tests with WordPress coding standards because `$args['after_widget'];` and `$args['before_widget'];` are not escaped...
What am I doing wrong? | These arguments contain arbitrary HTML and cannot be properly escaped. This is essentially a limitation on how Widgets code was designed and you can see in core Widget classes that no escaping is done on these.
Lessons to learn:
* WP core doesn't consistently adhere to its own coding standards (and getting there isn't considered worth targeted effort);
* passing around chunks of HTML is bad idea, in your own code pass *data* and render appropriately with proper escaping. |

3197: * the relative directory if $plugin is supplied. Default empty.

3203: function plugins_url( $path = '', $plugin = '' ) {

711: function plugin_dir_path( $file ) {

```
$plugin_dir = plugin_dir_path( __FILE__ );
$logfile = $plugin_dir . 'log.csv';

Something similar to setting posts or pages to "draft" but for users would function perfectly. Is there a way to do this? | The database table for users holds the `user_status` as integer:
```
$users_single_table = "CREATE TABLE $wpdb->users (
ID bigint(20) unsigned NOT NULL auto_increment,
user_login varchar(60) NOT NULL default '',
user_pass varchar(255) NOT NULL default '',

PRIMARY KEY (ID),
KEY user_login_key (user_login),
KEY user_nicename (user_nicename),
KEY user_email (user_email)
) $charset_collate;\n";
```
The `WP_Users` class at the moment doesn't have anything that would alter the state property, nor even hold that property.
[](https://i.stack.imgur.com/ta8H2.png)
There is one function inside `wp-admin/includes/ms.php` that may show you the path how to go.
```
update_user_status( $user_id, 'spam', '1' );
```
but loads only for multisite:
```
/wp-admin/includes/admin.php:
82 if ( is_multisite() ) {
83 require_once(ABSPATH . 'wp-admin/includes/ms-admin-filters.php');
84: require_once(ABSPATH . 'wp-admin/includes/ms.php');
85 require_once(ABSPATH . 'wp-admin/includes/ms-deprecated.php');
86 }
```
It looks like this:
```
function update_user_status( $id, $pref, $value, $deprecated = null ) {
global $wpdb;
if ( null !== $deprecated )
_deprecated_argument( __FUNCTION__, '3.0.2' );
$wpdb->update( $wpdb->users, array( sanitize_key( $pref ) => $value ), array( 'ID' => $id ) );
$user = new WP_User( $id );
clean_user_cache( $user );
if ( $pref == 'spam' ) {
if ( $value == 1 ) {
/**
* Fires after the user is marked as a SPAM user.
*
* @since 3.0.0
*
* @param int $id ID of the user marked as SPAM.
*/
do_action( 'make_spam_user', $id );
} else {
/**
* Fires after the user is marked as a HAM user. Opposite of SPAM.
*
* @since 3.0.0
*
* @param int $id ID of the user marked as HAM.
*/
do_action( 'make_ham_user', $id );
}
}
return $value;
}
```
You could use something similar and create **the action hook** `make_draft_user`, probable in your function `_20161214_update_user_status( $user_id, 'draft', '1' );`
Inside your very own `make_draft_user` hook you could define what to do.

$param = empty($args) ? 'post_tag' : $args;
$sql = $wpdb->prepare("SELECT posts.*, terms.name AS tag, count
FROM {$wpdb->posts} AS posts
LEFT JOIN {$wpdb->term_relationships} AS t_rel
ON (t_rel.object_id = posts.ID)
LEFT JOIN {$wpdb->term_taxonomy} AS t_tax

WHERE taxonomy LIKE '%s'
ORDER BY t_tax.count DESC, terms.name",
array( $param )
);
return $wpdb->get_results($sql);
}
```
It'll return you all the data from you posts table with `post_tag` term name and this terms post count. But it has a simple limitation and that is if you have one tag in multiple posts then the post will appear multiple time for each `post_tag` term it is attached to. You can use `GROUP BY posts.ID` to remove the duplicate posts, but it'll not give you all the terms and terms count. So with `GROUP BY posts.ID` the function will be like below-
```
function the_dramatist_order_posts_by_tag_count( $args = '' ) {
global $wpdb;
$param = empty($args) ? 'post_tag' : $args;
$sql = $wpdb->prepare("SELECT posts.*, terms.name AS tag, count
FROM {$wpdb->posts} AS posts
LEFT JOIN {$wpdb->term_relationships} AS t_rel
ON (t_rel.object_id = posts.ID)
LEFT JOIN {$wpdb->term_taxonomy} AS t_tax
ON (t_rel.term_taxonomy_id = t_tax.term_taxonomy_id)
LEFT JOIN {$wpdb->terms} AS terms
ON (terms.term_id = t_tax.term_id)
WHERE taxonomy LIKE '%s'
GROUP BY posts.ID
ORDER BY t_tax.count DESC, terms.name",
array( $param )
);
return $wpdb->get_results($sql);
}
```
Use which suits your need better.
This function works on `post_tag` taxonomy by default. If you want to use it with other taxonomy just pass it as parameter like `the_dramatist_order_posts_by_tag_count( 'category' )`
Better you do a `print_r` on this function before using it in production to understand the data structure.
Hope that helps. |

// "protected-fields" is a name for new JSON field
register_rest_field( 'tribe_venue', 'protected-fields', [

'schema' => null,

add_action( 'rest_api_init', 'create_api_posts_meta_field' );

return [
'venue' => $meta['_VenueVenue'] ?: '',
'address' => $meta['_VenueAddress'] ?: '',
'city' => $meta['_VenueCity'] ?: '',

Thank you | First of all you need to get all users calling `get_users()` function. Then you can use `count_user_posts()` to display post count for a user.
Try below code.
```

// Array of WP_User objects.
foreach ( $blogusers as $user ) {
echo 'Number of posts published by '.esc_html($user->display_name).': ' . count_user_posts( esc_html($user->id) ).'</br>';
}

```
<?php wp_list_authors('show_fullname=1&optioncount=1&orderby=post_count&order=DESC'); ?>

Also put theme's functions need to be override in if !function exist.
So what is the right way to override a theme function wrap in !function exist using a plugin?? | First of all you need to get all users calling `get_users()` function. Then you can use `count_user_posts()` to display post count for a user.
Try below code.
```
<?php
$blogusers = get_users();
// Array of WP_User objects.
foreach ( $blogusers as $user ) {
echo 'Number of posts published by '.esc_html($user->display_name).': ' . count_user_posts( esc_html($user->id) ).'</br>';
}
?>
```
**Update : You can easily use `wp_list_authors()` function also.**
```
<?php wp_list_authors('show_fullname=1&optioncount=1&orderby=post_count&order=DESC'); ?>

what's wrong plz can anyone tell me! | When a user [logs out](https://codex.wordpress.org/Function_Reference/wp_logout) the current user session is destroyed and no new pages can be loaded for which a user must be logged in. However, when you hit the 'back' button on your browser, it typically retrieves the page from the local cache. There is no contact with the server to see if the current session is still valid.
So, what you need to do is detect whether the backspace button has been hit and in that case check the validity of the session. This means there must be a piece of javacript included in the page, because this action needs to take place at the user side. I'm not a security expert, but the common way to detect the backspace goes like this:
```
window.onhashchange = function() {
.. your action ..
}
```
There are [some snags](https://stackoverflow.com/questions/25806608/how-to-detect-browser-back-button-event-cross-browser) to this method. Now, your action must be to call back to the server. That question [has been answered before](https://wordpress.stackexchange.com/questions/69814/check-if-user-is-logged-in-using-jquery) here on WPSE. |

Is there any way to prevent a WordPress plugin from searching for updates? | It is quite simple. All you have to do is add some code in a Custom Functions plugin.
Lets say you want to block the "Hello Dolly" plugin (comes prepacked with WordPress) from updating. In your "My Functions Plugin", `mycustomfunctions.php` (you can use any name really) you place the following:
```
/* Disable a plugin from updating */
function disable_plugin_updating( $value ) {
unset( $value->response['hello.php'] );
return $value;
}
add_filter( 'site_transient_update_plugins', 'disable_plugin_updating' );
```
That is all.
Now in case you want to prevent more than one plugins from updating, you just add additional lines to the above code like this:
```
/* Disable some plugins from updating */
function disable_plugin_updating( $value ) {
unset( $value->response['hello.php'] );
unset( $value->response[ 'akismet/akismet.php' ] );
return $value;
}
add_filter( 'site_transient_update_plugins', 'disable_plugin_updating' );
```
**Things to notice**:
* It is always best practice to **keep everything updated to the latest version** (for obvious reasons and mainly for vulnerability issues).
* We use `akismet/akismet.php` because `akismet.php` is within the plugin folder `akismet`
* In case you are not aware of what a Custom Functions plugin is (or don't have one) you can easily create one. Please have a look at an old -but still very valid- post on: [Creating a custom functions plugin for end users](http://justintadlock.com/archives/2011/02/02/creating-a-custom-functions-plugin-for-end-users).

* You can even use `myblog.com/123` as a short-url, or an easy to say url in a podcast, etc (maybe you need a bit of code customization to achieve this)
Is there any known performance issue about this permalink structure? | Note: we're talking here about the difference between permalinks `/%ID%/%name%/` and `%/name/%`. It would be a whole different story if we were to compare `/%ID%/%name%/` and `%/ID/%`.
Now, there are two use cases that affect performance:
**One. You have a permalink and WP needs to resolve it in order to serve the page requested.**
This means setting up the [WP class](https://developer.wordpress.org/reference/classes/wp/). The main function is at the bottom of the code. After init this involves calling [`parse_request`](https://developer.wordpress.org/reference/classes/wp/parse_request/). This checks whether rewrite rules exist for this particular page and checks query variables for validity. In this case we'd like to know whether processing `example.com/123/slug` takes more time than `example.com/slug`. For that to matter you would have to assume that the PHP string function that needs to handle a few bytes more has a significant impact on performance.
Once the requested url has been chopped into workable chunks, the action moves to [`parse_query`](https://developer.wordpress.org/reference/classes/wp_query/parse_query/), which in this case will be passed a query object either containing `name` or both `name` and `ID` (confusingly in the query object the ID is called `p`). A lot of handling is done, but nothing extra for including the ID in the query.
Next follow two hooks in (`pre_get_posts` and `posts_selection`) that are plugin territory, so impact on performance is unknown.
Now comes the main issue: will it take more time to query the database with one variable or with two? Both `ID` and `name` are stored in the `wp_posts` table in the database. So, there is no difference in the size of the table that will be queried. Also, both are unique, because when a post is stored this is checked (OP's assumption that including ID in the url will get rid of the `-2` in posts is wrong, unless you hack the saving procedure). As a result, it doesn't really matter whether you have to query all database rows for the unique `ID` or the unique `name`. The only difference in performance when providing both is that after the row with the `ID` has been found it will check if the `name` matches. That really is negligible.
**Two. You need to generate a permalink on a page.**
This is done by the [`get_permalink`](https://developer.wordpress.org/reference/functions/get_permalink/) function. For standard post types the procedure only adds some lengthy calculations if you are using `%category%`. For `ID` and `name` it is just a matter of search and replace in this line of code:
```
$permalink = home_url( str_replace( $rewritecode, $rewritereplace, $permalink ) );
```
The efficiency of [`str_replace`](https://www.php.net/manual/en/function.str-replace.php) depends on the size of the parameters that are passed to it, but since all possible rewriting parameters are passed, not just the one or two that are actually used, this does not affect performance.
For custom post types `get_permalink` refers to [`get_post_permalink`](https://developer.wordpress.org/reference/functions/get_post_permalink/), which involves more calculations anyway, but essentially winds down to the same search and replace. |

Is a text-domain necessary for a child theme? I am building a simple child theme with no text-domain declared. So, when I use strings which are to be translated, should I use the parent theme text-domain (yes parent theme has text-domain loaded and also has .mo/.po files).
For example adding this line in my child theme template
```
<?php __('Some String', 'parent-text-domain');>
```
Will be above string be translated?
Thanks in advance | **TL;DR:** If you use strings that are in the parent theme, exaclty how they are used in parent theme, you don't need to have a text domain for your child theme.
But if you use strings that aren't used in parent theme, to make them translatable, you'll need another text domain with related translation (`.mo`) files.
---
Translation workflow
--------------------
When WordPress encounter a string in a translatation function it:
1. Checks if a translation for required text domain has been loaded (via [`load_plugin_textdomain`](https://developer.wordpress.org/reference/functions/load_plugin_textdomain/) or [`load_theme_textdomain`](https://developer.wordpress.org/reference/functions/load_theme_textdomain/) or [`load_textdomain`](https://developer.wordpress.org/reference/functions/load_textdomain/)), if so go to point *3.*
2. Checks if translations folder (by default `wp-content/languages`) contains a matching textdomain file. Matching textdomain file is `"{$domain}-{$locale}.mo"` where `$domain` is the text domain of the string to translate and `$locale` is the current locale for the website. If that file is not found the original string is returned, otherwise it is loaded and WP forwards to next point.
3. When the textdomain is loaded, WP looks if the required string is contained in that file, if not the original string is returned, otherwiseWP forwards to next point.
4. If the found translated string needs some singular / plural resolution (e.g. when using [`_n()`](https://developer.wordpress.org/reference/functions/_n/)) those are done. Otherwise WP forwards to next point.
5. Filter hooks are applied on the translated string (see <https://developer.wordpress.org/?s=gettext&post_type%5B%5D=wp-parser-hook>) and finally the result is returned.
So?
---
When you use parent theme text domain in translation function from child theme (assuming parent theme ships and loads the textdomain file, or it has a translation file in translations folder), WordPress will arrive at point *3.* in the list above, and so if the string is available in the file (because used in parent theme) it will be translated, otherwise not so.
It means that custom strings in parent theme needs own translation file.
In theory, it is possible to use parent textdomain in another translation file, because WordPress is capable to load more times the same text domain, "merging" them, but that has issues because only one file may exists in the format `"{$domain}-{$locale}.mo"` in translation folders (see point *2.* in the list above).
So, in conclusion, the only viable way to make a child theme translatable, if it contains strings not used in parent theme, is to use own text domain and own translation file. |

] | I need to get all meta keys/custom fields that are assigned to a post type.
I don't want to get the `post_meta` values for `post_meta` assigned to a particular post, or to all posts of a post type.
But, I want to get all possible custom fields that are 'assigned' to a post type.
I have looked and I am starting to worry that it's not possible, as maybe `post_meta` isn't 'registered' but only appears in the database when a post is saved?
I want to get all post meta information for a post type, in the same way I can get all taxonomies' information, assigned to a post type.
I want to be able to do:
```
get_post_meta_information_for_post_type($post_type);
```
and get something like:
```
array('custom_meta_key_1', 'custom_meta_key_2);
```
... regardless of whether or not there is even one single existing post of that post type.
Please tell me it's possible (and how to do it :))?
Thanks | Answer by @Gareth Gillman definitely works but its an expensive query if we have hundreds of posts.
The function below is less expensive and using the wp native function [get\_post\_custom\_keys()](https://codex.wordpress.org/Function_Reference/get_post_custom_keys)
```
if ( ! function_exists( 'us_get_meta_keys_for_post_type' ) ) :
function us_get_meta_keys_for_post_type( $post_type, $sample_size = 5 ) {
$meta_keys = array();
$posts = get_posts( array( 'post_type' => $post_type, 'limit' => $sample_size ) );
foreach ( $posts as $post ) {
$post_meta_keys = get_post_custom_keys( $post->ID );
$meta_keys = array_merge( $meta_keys, $post_meta_keys );
}
// Use array_unique to remove duplicate meta_keys that we received from all posts
// Use array_values to reset the index of the array
return array_values( array_unique( $meta_keys ) );
}
endif;
```
You may use the $sample\_size param to include more posts in the loop.
Hope it helps someone. |

] | I'm trying to check the output of a variable in my functions.php file that runs after a new woocommerce order. The code will get the order time from a new order and store it in a variable for me to use elsewhere the code being:
```
$meeting_time = wc_get_order_item_meta($order_id, 'Time');
print_r($meeting_time);
```
I've tried a few ways to print the information:
* print\_r
* javascript popup box
* writing to error log
but I can't seem to get any of these to work as my php knowledge isn't very good.
I want to be able to see the output of the variable to make sure it's returning what I want.
Is anyone able to assist me?
Please and thankyou. | You can use [`var_dump()`](http://php.net/manual/en/function.var-dump.php) instead of `print_r()` - you get the type and the value of the variable and it will also work when your variable holds `FALSE` or `NULL`.
```
print_r( false ); # doesn't output anything
var_dump( false ); # output: bool(false)
print_r( NULL ); # doesn't output anything
var_dump( NULL ); # output: NULL
```
If you have arrays or objects to inspect, you could use a plugin like [Kint Debugger](https://wordpress.org/plugins/kint-debugger/) to format the output into a more readable format. |

If so, I could not find a restart command on my phpmyadmin panel. | While I know version control approach to be used in practice, I don't think it's too common. WP has weak version control practices in general, so development of extensions doesn't quite plan for such.
Example of specific scenario which will cause issues might be changes in template hierarchy. Let's say you customized `single.php` in version control. Then upstream theme rearranged things and got rid of `single.php` altogether in favor of more generic `singular.php`. Suddenly your changes hang in the air without template to apply them to, essentially your merge is blocked and you have to re-develop your changes on top of a new situation.
With child theme your template will stay in place and continue to work, although occasional updates will be required in some cases as well.
In a nutshell I would consider version control to be essentially a *fork* to maintain, while child theme would be a downstream extension (under your full control) with upstream *dependency*.
In my subjective opinion maintaining a fork would be harder on resources in most cases. I would reserve it to solutions which *cannot* be achieved with a child theme. |

Thanks! | Here you've did something wrong with `$wpdb->table_name`. It will only return the default WordPress table names. Not custom table names. And also when you call `$wpdb->prepare` then pass the parameter as array. So your function will be like below-
```
function get_info($postid) {
global $wpdb;
// Here I assumed that your table name is '{$wpdb->prefix}places_locator'
$sql = $wpdb->prepare("SELECT post_id, address, phone, email
FROM {$wpdb->prefix}places_locator
WHERE post_id = '%d'",
array( $postid )
);
$info = $wpdb->get_results($sql);
return $info;
}
```
Now if you do `print_r` on `get_info()` with parameter post ID then it will return you value.
Use like below-
```
print_r(get_info(1)); // Here I assumed your post ID is 1

``` | This pattern can be reduced to two main sections, large box and grid boxes.
And you said you were having trouble closing the grid boxes when your posts are less than 10, an easy way to close off the grid would be to check if the current post is equal to the total posts.
Here is my interpretation of your loop:
```
<?php
if (have_posts()) :
while (have_posts()) :
the_post();
$total_posts = $wp_query->post_count;
$current_post = $wp_query->current_post;
// Large boxes
if (in_array($current_post, array(1, 6))) : ?>
<article class="large"></article>
<?php
elseif ($current_post > 1 && $current_post < 6 || $current_post > 6) :
// Open grid box
in_array($current_post, array(2, 7)) ? "<div class='grid'>" : "";
?>
<article></article>
<?php
// Close grid box
in_array($current_post, array(6, $total_posts)) ? "</div> <!-- .grid -->" : "";
// Add seperator
$current_post == 6 ? "<div id='edit'></div> <!-- #edit -->" : "";

``` | Use Ajax API provided by WordPress.
In first time, fix your Ajax request :
```
<script>
$(".post-link").click(function(){
var post_id = $(this).attr("rel"); //this is the post id
$("#post-container").html("content loading");
$.ajax({
url: myapiurl.ajax_url,

success: function(data) {
// What I have to do...
},
fail: {
// What I have to do...
}
});
return false;
});

```
Now, you have to create your WordPress treatment. You can put this code in your functions.php or in a plugin file.
```
add_action( 'admin_enqueue_scripts', 'my_ajax_scripts' );
function my_ajax_scripts() {
wp_localize_script( 'ajaxRequestId', 'myapiurl', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
```
And then... your function that retrieve your posts
```
function my_php_function_name() {
// What I have to do...
}
```
PS: Never put code in root install folder. Use functions.php of your theme, or create plugin. It's very important for maintainability and security. Have fun :) |

Here ***bedrijven*** is your category slug.
As you said the above method hasn't worked for you, so here I'm suggesting another method-
First remove the first method's full code. Then follow this below method step by step-
**Step 1:**
In your theme's `functions.php` put the below code block-
```
function the_dramatist_register_category_styles() {
wp_register_style( 'post-template', get_stylesheet_directory_uri() . '/layout-interieur.css' );
}
add_action( 'wp_enqueue_scripts', 'the_dramatist_register_category_styles' );
```
By this above code block we are registering your stylesheet file at ***WordPress***. So we can call it anytime.
**Step 2:**
Now go to your `category-bedrijven.php` file and inside this file put the below code-
```
<?php wp_enqueue_style('post-template'); ?>
```
It'll must work if you do it right.
Hope that helps. |

A short piece of code showing how to access the page custom field would be really useful. | Sometimes WordPress is criticized treating everything as a `post`. The matter of fact is, post type `pages`, post type `post` - both are actually Post in database. So no post will collide with any page ID. :)
So simply a `get_post_meta()` is enough.
But if you still want something specific to Pages, you can use:
```
if( is_page() ) get_post_meta(...);
```
Yes, you can use `get_post_meta()` outside the loop. But instead of passing the post\_id using `get_the_ID()` you have to pass the post\_id manually. |

``` | You have to consider that you're dealing with [`substr()`](http://php.net/manual/en/function.substr.php) a *string* related function as the **str** in the function name indicates. That does mean that the parameter `$string` you give actually has to be of the [type `string`](http://php.net/manual/en/language.types.intro.php).
[`get_post_meta()`](https://developer.wordpress.org/reference/functions/get_post_meta/) on the other hand does just give you back whatever type you saved in the first place. So it isn't guaranteed that your getting back a string - you have to make sure of that yourself. Which you can do by [type casting](http://php.net/manual/en/language.types.type-juggling.php) the value, variable you receive.
So far so good, let's put it together:
```
$custom_field = (string) get_post_meta( $post->ID, "CUSTOMFIELD", true );

Thanks,
libor | Expanding a bit on the answer from @dgarceran
Generally, using the `WP_Query` class is probably a good idea for querying posts.
We'll want to pass arguments to that query.
In your case we'll likely want use one of the following:
1. "**Custom Field Parameters**" - `meta_query`
2. "**Taxonomy Parameters**" - `tax_query`
For a nearly comprehensive example of all the options I like to reference this gist: <https://gist.github.com/luetkemj/2023628>.
Also see the Codex: <https://codex.wordpress.org/Class_Reference/WP_Query>
Both take an array of associative arrays e.g.
**Note**: I'll be using syntax that is compatible with as of PHP 5.4
```
$meta_query_args = [
[
'key' => 'season',
'value' => [ '2015', '2016' ],
'compare' => 'IN',
],
];
```
We can bring those arguments into our instance of `WP_Query`
```
$args = [
'post_type' => 'player',
'posts_per_page' => 100, // Set this to a reasonable limit
'meta_query' => $meta_query_args,
];
$the_query = new WP_Query( $args );
```
What's happenning at this point is WordPress is going to check all posts that match your **custom post type** `player`. Then, it will query the metadata you've set with key `season`. Any posts matching `2015` or `2016` will be returned.
**Note:** using `meta_query` this way isn't generally recommended because it's a little heavy on the database. The consensus seems to be that querying taxonomies is more performant (don't quote me on that, couldn't find my source)
So for a quick alternative, I reccomend the following example:
```
$tax_query_args = [
[
'taxonomy' => 'season',
'field' => 'slug',
'terms' => [ '2015', '2016' ],
'operator' => 'IN',
],
];
$args = [
'post_type' => 'player',
'posts_per_page' => 100, // Set this to a reasonable limit
'tax_query' => $tax_query_args,
];
$the_query = new WP_Query( $args );
```
Now we can actually loop through the data, here's some example markup:
```
<section class="season-list">
<?php while ( $the_query->have_posts() ) : $the_query->the_post();
$post_id = get_the_ID();
// $season = get_post_meta( $post_id, 'season', true ); // example if you are still going to use post meta
$season = wp_get_object_terms( $post_id, 'season', [ 'fields' => 'names' ] );
?>
<h3><?php the_title(); ?></h3>
<p><?php echo __( 'Season: ' ) . sanitize_text_field( implode( $season ) ); ?></p>
<?php endwhile; ?>
</section>
```
When you use `WP_Query` especially in templates, make sure you end with `wp_reset_postdata();`
Putting it altogether (tl;dr)
```
$tax_query_args = [
[
'taxonomy' => 'season',
'field' => 'slug',
'terms' => [ '2015', '2016' ],
'operator' => 'IN',
],
];
$args = [
'post_type' => 'player',
'posts_per_page' => 100, // Set this to a reasonable limit
'tax_query' => $tax_query_args,
];
$the_query = new WP_Query( $args );
?>
<section class="season-list">
<?php while ( $the_query->have_posts() ) : $the_query->the_post();
$post_id = get_the_ID();
// $season = get_post_meta( $post_id, 'season', true ); // example if you are still going to use post meta
$season = wp_get_object_terms( $post_id, 'season', [ 'fields' => 'names' ] );
?>
<h3><?php the_title(); ?></h3>
<p><?php echo __( 'Season: ' ) . sanitize_text_field( implode( $season ) ); ?></p>
<?php endwhile; ?>
</section>
<?php
wp_reset_postdata();
```

Thanks. | A post or page has only one title, the title tag `<title>` is the document title.
The filter `wp_title` filters the output of `wp_title()` function, which was used before to output the title of the document. In WordPress 4.1, the title-tag support in themes was introduced and [`wp_get_document_title()`](https://developer.wordpress.org/reference/functions/wp_get_document_title/) is used instead of `wp_title()`. So, if your theme supports `title-tag`, `wp_title` filter has not effect, but you can use a other filters:
[`pre_get_document_title`](https://developer.wordpress.org/reference/hooks/pre_get_document_title/) to set a new title
```
add_filter( 'pre_get_document_title', 'cyb_change_page_title' );
function cyb_change_page_title () {
return "Custom title";
}
```
[`document_title_separator`](https://developer.wordpress.org/reference/hooks/document_title_separator/) to filter the title separator
```
add_filter('document_title_separator', 'cyb_change_document_title_separator');
function cyb_change_document_title_separator ( $sep ) {
return "|";
}
```
[`documente_title_parts`](https://developer.wordpress.org/reference/hooks/document_title_parts/) to filter different parts of the title: title, page number, tagline and site name.
```
add_filter( 'document_title_parts', 'cyb_change_document_title_parts' );
function cyb_change_document_title_parts ( $title_parts ) {
$title_parts['title'] = 'Custom title';
$title_parts['page'] = 54;
$title_parts['tagline'] = "Custom tagline";
$title_parts['site'] = "My Site"; // When not on home page
return $title_parts;
}
```
PD: You can use [`current_theme_supports( 'title-tag' )`](https://developer.wordpress.org/reference/functions/current_theme_supports/) to check if theme supports `title-tag` or not. |

Will it be best to end function `merrychristmas_happynewyear` with `die()`, `die(0)`, `wp_die()`, or something else and why? | Using `wp_die()` is the best of those options.
As others have noted, there are many reasons to prefer a WordPress-specific function over the plain `die` or `exit`:
* It allows other plugins to hook into the actions called by `wp_die()`.
* It allows a special handler for exiting to be used based on context (the behavior of `wp_die()` is tailored based on whether the request is an Ajax request or not).
* It makes it possible to test your code.
The last one is more important, which is why [I added that note to the Codex](https://codex.wordpress.org/index.php?title=AJAX_in_Plugins&diff=148870&oldid=148219). If you want to [create unit/integration tests](http://codesymphony.co/wp-ajax-plugin-unit-testing/) for your code, you will not be able to test a function that calls `exit` or `die` directly. It will terminate the script, like it is supposed to. The way that WordPress's own tests are set up to avoid this (for the Ajax callbacks that it has tests for), is to hook into the actions triggered by `wp_die()` and throw an exception. This allows the exception to be caught within the test, and the output of the callback (if any) to be analyzed.
The only time that you would use `die` or `exit` is if you want to bypass any special handling from `wp_die()` and kill the execution immediately. There are some places where WordPress does this (and other places where it might use `die` directly just because the handling from `wp_die()` is not important, or nobody has attempted to create tests for a piece of code yet, so it was overlooked). Remember that this also makes your code more difficult to test, so it would generally only be used in code that isn't in a function body anyway (like WordPress does in `admin-ajax.php`). So if the handling from `wp_die()` is specifically not desired, or you are killing the script at a certain point as a precaution (like `admin-ajax.php` does, expecting that usually an Ajax callback will have already properly exited), then you might consider using `die` directly.
In terms of `wp_die()` vs `wp_die( 0 )`, which you should use depends on what is handling the response of that Ajax request on the front end. If it is expecting a particular response body, then you need to pass that message (or integer, in this case) to `wp_die()`. If all it is listening for is the response being successful (`200` response code or whatever), then there is no need to pass anything to `wp_die()`. I would note, though, that ending with `wp_die( 0 )` would make the response indistinguishable from the default `admin-ajax.php` response. So ending with `0` does not tell you whether your callback was hooked up properly and actually ran. A different message would be better.
As pointed out in other answers, you will often find `wp_send_json()` et al. to be helpful if you are sending a JSON response back, which is generally a good idea. This is also superior to just calling `wp_die()` with a code, because you can pass much more information back in a JSON object, if needed. Using `wp_send_json_success()` and `wp_send_json_error()` will also send the success/error message back in a standard format that any JS Ajax helper functions provided by WordPress will be able to understand (like [`wp.ajax`](https://core.trac.wordpress.org/browser/trunk/src/wp-includes/js/wp-util.js?rev=37851#L99)).
**TL;DR:** You should probably always use `wp_die()`, whether in an Ajax callback or not. Even better, send information back with `wp_send_json()` and friends. |

I think you also need to define `FTP_BASE`.
You also need to enable ssh upgrade access. From the Codex:
Enabling SSH Upgrade Access
---------------------------
**There are two ways to upgrade using SSH2.**
The first is to use the [SSH SFTP Updater Support plugin](http://wordpress.org/plugins/ssh-sftp-updater-support/). The second is to use the built-in SSH2 upgrader, which requires the pecl SSH2 extension be installed.
To install the pecl SSH2 extension you will need to issue a command similar to the following or talk to your web hosting provider to get this installed:
```
pecl install ssh2
```
After installing the pecl ssh2 extension you will need to modify your php configuration to automatically load this extension.
pecl is provided by the pear package in most linux distributions. To install pecl in Redhat/Fedora/CentOS:
```
yum -y install php-pear
```
To install pecl in Debian/Ubuntu:
```
apt-get install php-pear
```
It is recommended to use a private key that is not pass-phrase protected. There have been numerous reports that pass phrase protected private keys do not work properly. If you decide to try a pass phrase protected private key you will need to enter the pass phrase for the private key as FTP\_PASS, or entering it in the "Password" field in the presented credential field when installing updates. |

wp_enqueue_style( 'twentyfifteen-ie', get_template_directory_uri() . '/css/ie.css', array( 'twentyfifteen-style' ), '20141010' );
```
-
```
<script src="<?php echo esc_url( get_template_directory_uri() ); ?>/js/html5.js"></script>
```
I would say that that `get_template_directory_uri()` does not need to be generated as the URL cannot be manipulated externally. | In that function we find a hook:
```
return apply_filters(
'template_directory_uri',
$template_dir_uri,
$template,
$theme_root_uri
);
```
So, yes, the URI can be changed by plugins, and you should escape its returned value.
The same principle applies to all WordPress URI functions, like `get_home_url()`, `get_site_url()` and so on. Keep in mind that there are not only good plugin developers out there. Some make mistakes, maybe just very small ones that happen only in some circumstances.
In case of `wp_enqueue_style()`, WordPress **does** escape the URL by default. But that is a wrapper for the **global** `WP_Styles` instance, and this in turn [can be replaced easily](https://wordpress.stackexchange.com/a/108364/73) – even with a less safe version. That's not very likely, but you should be aware of this possibility.
Unfortunately, WP itself doesn't follow the *better safe than sorry* directive. It doesn't even escape translations. My advice is not to look at the core themes for best practices. Always look at the source of the data and see if it can be compromised. |

What's wrong with us. | Try below code.
```
add_action('add_meta_boxes','create_events_metaboxes');
function create_events_metaboxes() {
add_meta_box('events-meta-box','Events Details','show_events_metaboxes','events-lists');
}
function show_events_metaboxes($post){ echo 'Hello Meta box'; }
```
Hope this will helps you.

``` | That error suggests that the `WXR_Parser` class is already "running" or declared. It's possible that a theme or another plugin has incorporated that class and did not check if it existed already before initializing. ie. `if ( ! class_exists( 'WXR_Parser' ) )`.
To locate the source of the conflict, deactivate each *theme and plugin* one-by-one. You should be left with just a default theme active (ie. TwentyFifteen). |

I am currently using WordPress 4.7. | No, it is not a bug. This is how core handles it. If you look into `/wp-includes/comment-template.php`, you'll notice, that the only difference in `<form>` element, is `novalidate` attribute added, when `current_theme_supports( 'html5', 'comment-form' )` is true. But there are other html elements within comment form, which are affected by theme's choice of html5 support. For example:
input field for email ( `type="email"` - html5, `type="text"` - xhtml ), and input field for url ( `type="url"` - html5, `type="text"` - xhtml ).
I would not recommend to remove theme support for html5. WordPress, now, builds our documents with `<!DOCTYPE html>`, which means, HTML5. If we do remove support, our document will not validate as correct XTML5.
So, how to deal with this offending `novalidate` attribute? Simple jQuery script will fix it.
Create file `removenovalidate.js` and put the code below in it:
```
jQuery( document ).ready(function($) {
$('#commentform').removeAttr('novalidate');
});
```
Save this file to your theme's folder. Add the code below to your theme's `functions.php`:
```
function fpw_enqueue_scripts() {
if ( is_single() ) {
wp_register_script( 'fpw_remove_novalidate', get_stylesheet_directory_uri() . '/removenovalidate.js', array( 'jquery' ), false, true );
wp_enqueue_script( 'fpw_remove_novalidate' );
}
}
add_action('wp_enqueue_scripts', 'fpw_enqueue_scripts', 10 );
```
All done. Your comments form will validate now. |

250,521 | <p>I have an issue reaching my Wordpress login page. <a href="http://www.everydaytherapy.ie/wp-admin" rel="nofollow noreferrer">http://www.everydaytherapy.ie/wp-admin</a>
I am redirected and a drop down menu appears to login in. But not the proper Wordpress login screen (check the URL yourself). I still tried to login but my details didn't work for it. It would just reset. I have tried deleting the .htaccess file, adding the URL's to the config.php file and anything else I could find online. I went into phpMyadmin and the tables seem correct. I deactivated all my plugin's and even my theme and still the same issue.
Any help would be greatly appreciated!</p>
