Not only is that a pain, but not all user's are savy enough to realize they can do this. | I've been searching around for the same answer to your question and running into the exact same issues, and really appreciate your thorough research. I'm definitely +1 here for proposing this addition!
To attempt to answer 2) - I don't think there's a good reason to exclude it. I think WordPress's taxonomy terms are woefully lacking in features compared to the post and user entities (seeing as how term meta came much later, after post and user meta), and would like to see that change.
To answer 1) - I don't know how much *better* this is than your solution, but the workaround I've come up with involves filtering the taxonomy list via the `get_terms_args` filter, and then manually inserting a select dropdown + filter button in client-side JS. Here's a sample of my setup (modified to not use my specific classes or constants), which is filtering by a certain term meta field:
**PHP Logic**
```
// @see https://developer.wordpress.org/reference/hooks/get_terms_args/
add_filter( 'get_terms_args', 'taxonomy_filter', 10, 2 );
function taxonomy_filter( $args, $taxonomies ) {
global $pagenow;
if ( 'edit-tags.php' !== $pagenow || ! in_array( 'taxonomy-name', $taxonomies, true ) ) { return $args; }
// Sort by most recently added terms, instead of alphabetically
$args['orderby'] = 'term_id';
$args['order'] = 'desc';
// Filter by term meta
$meta_key = ( isset( $_GET['meta_key'] ) ) ? sanitize_text_field( $_GET['meta_key'] ) : null;
$meta_value = ( isset( $_GET['meta_value'] ) ) ? sanitize_text_field( $_GET['meta_value'] ) : null;
if ( 'meta-filter' === $meta_key && $meta_value ) {
$args['meta_key'] = $meta_key;
$args['meta_value'] = $meta_value;
}
// Note: for more complex filtering, use the $args['meta_query'] array.
return $args;
}
```
At this point, you should be able to see this working simply by going to (e.g.) `yoursite.com/wp-admin/edit-tags.php?taxonomy=taxonomy-name&meta_key=meta-filter&meta_value=foobar`.
**Client-side jQuery logic**
(Make sure you include this file in `wp_enqueue_script()`, but only when `$pagenow === 'edit-tags.php'`).
```
/**
* Param helpers
*/
// Get params in a JS object
var params = {};
window.location.search.substr(1).split( '&' ).forEach(function(item) {
params[ item.split( '=' )[0] ] = item.split( '=' )[1];
});
// Return param string based on the params object
function setParams() {
var string = '?';
for ( key in params ) {
var value = params[ key ];
string += key + '=' + value + '&';
}
return string.slice(0, -1); // Remove trailing &
}
/**
* Add dropdown filters + functionality to term tables
*/
if ( 'taxonomy-name' === params.taxonomy ) {
// Create the dropdown menu & HTML
$( document.querySelector( '.tablenav .bulkactions' ) ).after( '\
<div class="alignleft actions"> \
<select id="js-filter-dropdown"> \
<option value="">Term Meta Filter</option> \
<option value="foo">Foo</option> \
<option value="bar">Bar</option> \
<option value="baz">Baz</option> \
</select> \
<button id="js-filter" class="button" type="button">Filter</button> \
</div> \
' );
// If we're already filtering the view, have the dropdown reflect that
var value = decodeURIComponent( params.meta_value ).replace(/\+/g, ' ');
$( '#js-filter-dropdown' ).find( 'option[value="' + value + '"]' ).prop( 'selected', true );
// Set up the button action - see taxonomy_filter() for server-side filtering
$( '#js-filter' ).click(function() {
var value = $( '#js-filter-dropdown' ).val();
if ( value ) {
params.meta_key = 'meta-filter';
params.meta_value = encodeURIComponent( value );
} else {
delete params.meta_key;
delete params.meta_value;
}
window.location.search = setParams();
});
}
```

My question is, how do you use `active_callback` to check two settings? It works on one setting but I need it to check two settings. Do I need to create a function? | Maybe I'm misreading your question, but combining these two conditions in one anonymous function doesn't look that difficult:
```
'active_callback' => function() use ( $wp_customize ) {
$condition1 == $wp_customize->get_setting( 'twsa_show_schedule' )->value();
$condition2 == $wp_customize->get_setting( 'twsa_show_active' )->value();
return ($condition1 && $condition2);
}

<http://php.net/manual/en/control-structures.alternative-syntax.php>
PHP offers an alternative syntax for some of its control structures; namely, if, while, for, foreach, and switch. In each case, the basic form of the alternate syntax is to change the opening brace to a colon (:) and the closing brace to endif;, endwhile;, endfor;, endforeach;, or endswitch;, respectively. | You just need an else block:
```
//templating syntax
if($condOne):
//do stuff if $condOne is true
elseif($condTwo):
//do stuff if $condOne is false and $condTwo is true
else:
//do stuff if both $condOne and $condTwo are false
endif;
//braces syntax
if($condOne){
//do stuff if $condOne is true
}elseif($condTwo){
//do stuff if $condOne is false and $condTwo is true
else{
//do stuff if both $condOne and $condTwo are false
}
```
Regarding "it's probably good practice to finish with 'endif'", `endif` is only used when you are using the templating syntax:
```
if():
//do stuff
endif;
```
the alternative is regular braces syntax:
```
if(){
//do stuff
}
```
The former is preferable when you are outputting html by dropping out of php with a closing php tag, because an `endif` is easier to match up than a closing brace:
```
<?php if($someCondition):?>
<h1>Hello <?=$userName?>, how are you today?</h1>
<ul>
<?php foreach($someArray as $key => $value):?>
<li><?=$key?> : <?=$value?></li>
<?php endforeach;?>
</ul>
<?php endif;?>
```
VS:
```
<?php if($someCondition){?>
<h1>Hello <?=$userName?>, how are you today?</h1>
<ul>
<?php foreach($someArray as $key => $value){?>
<li><?=$key?> : <?=$value?></li>
<?php }?>
</ul>
<?php }?>
```
However when writting code that does not drop out of php mode, the latter is far more common and arguable easier to read:
```
$out=[];
if($someCondition){
$out[$username]=[];
foreach($someArray as $key => $value){
$out[$username][] = $key . ' : ' . $value;
}
}
``` |

Ho do this? | WordPress comes with built in support for using AJAX calls from within your plugins or themes functions.php.
Following is the sample example:
Javascript code:
```
jQuery( document ).on( 'click', '.event-trigger', function() {
var ajax_url = "<?php echo admin_url( 'admin-ajax.php' ); ?>"; //You can define this parameter globally as well.
jQuery.ajax({
url : ajax_url,
type : 'post',
data : {
action : 'youraction',
param1: param1,
param2: param2
},
success : function( response ) {
alert(response)
}
});
})
```
Write the following code in plugin file or functions.php file in your theme:
```
add_action( 'wp_ajax_nopriv_youraction', 'your_functionname' ); //This action calls for non-authenticated users as well
add_action( 'wp_ajax_post_youraction', 'your_functionname' ); //This action calls only for authenticated user
function your_functionname() {
//your code goes here
}
```

Please it's been days since I've started trying to solve this.
Thanks all.</p>
<p>P.s.: Please, do not suggest any plugin. I've tried already many, and none of them worked. </p>

Thanks all.
P.s.: Please, do not suggest any plugin. I've tried already many, and none of them worked. | WordPress comes with built in support for using AJAX calls from within your plugins or themes functions.php.
Following is the sample example:
Javascript code:
```
jQuery( document ).on( 'click', '.event-trigger', function() {
var ajax_url = "<?php echo admin_url( 'admin-ajax.php' ); ?>"; //You can define this parameter globally as well.
jQuery.ajax({
url : ajax_url,
type : 'post',
data : {
action : 'youraction',
param1: param1,
param2: param2
},
success : function( response ) {
alert(response)
}
});
})
```
Write the following code in plugin file or functions.php file in your theme:
```
add_action( 'wp_ajax_nopriv_youraction', 'your_functionname' ); //This action calls for non-authenticated users as well
add_action( 'wp_ajax_post_youraction', 'your_functionname' ); //This action calls only for authenticated user
function your_functionname() {
//your code goes here
}
```
Refer [Ajax Example](https://premium.wpmudev.org/blog/using-ajax-with-wordpress/) for more details. |
268,563 | <p>I was able to echo out all terms belonging to a custom taxonomy using the code below:</p>
<pre><code>$args = array('post_type' => 'my_post_type','number' => '999');

[
'hide_empty' => true,

Can anyone point out the issue on my code. | Your code is wrong. I don't know how it is working in your localhost. Cause-
1. You are calling `get_terms()` with 3 parameters which actually accepts 2 parameters. The last one is extra.
2. And secondly `get_terms()` returns all the terms of a taxonomy, not the terms associated with a post.
For getting the terms associated for a post you can use [`wp_get_post_terms`](https://codex.wordpress.org/Function_Reference/wp_get_post_terms).
**Usage of `wp_get_post_terms` inside *WordPress* loop-**
For each post you'll get the post's terms by calling `wp_get_post_terms` like below-
```
//Do something if a specific array value exists within a post
$term_list = wp_get_post_terms($post->ID, 'your_taxonomy', array("fields" => "all"));
// Then you can run a foreach loop to show the taxonomy terms infront.
foreach($term_list as $term_single) {
echo $term_single->slug; //do something here
}
```
And for outside of the loop-
```
// Do something if a specific array value exists within a post
// And somehow you need to get the post ID to pas it to below.
$term_list = wp_get_post_terms($post_id, 'your_taxonomy', array("fields" => "all"));
// Then you can run a foreach loop to show the taxonomy terms infront.
foreach($term_list as $term_single) {
echo $term_single->slug; //do something here
}
```

The plugin has two pieces. First off, I tap into the `template_include` filter, and I return the path to the template file (test-template.php).
Next, I have a new extension of `Walker_Page`, called `Walker_Page_New` in this example. In the file, it is a word for word copy of `Walker_Page`.

Other than a smaller Blog posting what can we due to limit these disconnections? | Your code is wrong. I don't know how it is working in your localhost. Cause-
1. You are calling `get_terms()` with 3 parameters which actually accepts 2 parameters. The last one is extra.
2. And secondly `get_terms()` returns all the terms of a taxonomy, not the terms associated with a post.
For getting the terms associated for a post you can use [`wp_get_post_terms`](https://codex.wordpress.org/Function_Reference/wp_get_post_terms).
**Usage of `wp_get_post_terms` inside *WordPress* loop-**
For each post you'll get the post's terms by calling `wp_get_post_terms` like below-
```
//Do something if a specific array value exists within a post
$term_list = wp_get_post_terms($post->ID, 'your_taxonomy', array("fields" => "all"));
// Then you can run a foreach loop to show the taxonomy terms infront.
foreach($term_list as $term_single) {
echo $term_single->slug; //do something here
}
```
And for outside of the loop-
```
// Do something if a specific array value exists within a post
// And somehow you need to get the post ID to pas it to below.
$term_list = wp_get_post_terms($post_id, 'your_taxonomy', array("fields" => "all"));
// Then you can run a foreach loop to show the taxonomy terms infront.
foreach($term_list as $term_single) {
echo $term_single->slug; //do something here
}
```
Hope that helps. |

Any other ideas or solutions to accomplish this? | The capability required to delete posts is `delete_posts`. If you want them to be able to delete their own published posts, the capability is `delete_published_posts`.
The capability required to view the administration panel is `read`. Subscribers have this capability natively, so unless you have removed it, subscribers can access the backend.
I would write a simple plugin that upon activation adds the required capabilities to the subscriber role and upon deactivation removes those caps.
Then in your theme, you can check for:
```
if( current_user_can( 'delete_posts' ) ) {
//* Show delete link
}
```
Because the subscriber role doesn't have the capability to `delete_others_posts`, the link will not show on posts that they didn't author, and they will not be able to delete posts that they did not publish.
```
/**
* Plugin Name: WordPress StackExchange Question 268755
* Description: Allow subscribers to delete their own posts
**/
//* On activation, add the capabilities to the subscriber role
register_activation_hook( __FILE__, 'wpse_268755_activation' );
function wpse_268755_activation() {
$subscriber = get_role( 'subscriber' );
$subscriber->add_cap( 'delete_posts' );
$subscriber->add_cap( 'delete_published_posts' );
}
//* On deactivation, remove the capabilities from the subscriber role
register_deactivation_hook( __FILE__, 'wpse_268755_deactivation' );
function wpse_268755_deactivation() {
$subscriber = get_role( 'subscriber' );
$subscriber->remove_cap( 'delete_posts' );
$subscriber->remove_cap( 'delete_published_posts' );
}
```
Without giving the user and/or role the capability to delete a post, then they won't be able to do so, even if you show them a delete link. Likewise, a user or role can delete a post if they have the capability even if you don't show a delete link, it will just be more difficult for them. |

Is there some kind of timing issue here perhaps? Maybe I am using the wrong filter? Or is this possibly a WP bug?
Thanks for any help! | I was able to successfully change the datepicker's strings to a different locale for a single page using the [`switch_to_locale()`](https://developer.wordpress.org/reference/functions/switch_to_locale/) function introduced in [WordPress v4.7](https://make.wordpress.org/core/2016/11/07/user-admin-languages-and-locale-switching-in-4-7/).
`switch_to_locale()` will modify the global `$wp_locale` variable which is used by `wp_localize_jquery_ui_datepicker()`. Changing the locale with the `locale` filter alone does not overwrite `$wp_locale`.
```
/**
* Use switch_to_locale() on a special page.
* This needs to be done early.
*/
add_action( 'pre_get_posts', 'wpse_change_language' );
function wpse_change_language( $query ) {

```
---
After adding the caps to the role, to solve the rest you could either
1. keep `blockusers_init` and ditch `get_delete_post_link` for an ajax delete.
2. ditch the `blockusers_init` function and do a conditional redirect.
I'll give some ideas on each. I prefer ditching `get_delete_post_link` in this instance.
**Several steps below, so be aware the code is provided as a guide only. Rewrite and rename things as needed.**
---
Ditch `get_delete_post_link` aka AJAX Delete
--------------------------------------------
replace `get_delete_post_link` line with something like this:
```
<?php if( current_user_can( 'delete_post' ) ) : ?>
<a href="#" data-id="<?php the_ID() ?>" data-nonce="<?php echo wp_create_nonce('ajax_delete_post_nonce') ?>" class="delete-post">delete</a>
<?php endif ?>
```
**Enqueue some JS**
in file: *functions.php*
```
function delete_post_ajax() {
wp_enqueue_script( 'delete_ajax', get_template_directory_uri() . '/js/my_script.js', array( 'jquery' ), '1.0.0', true );
wp_localize_script( 'delete_ajax', 'TheAjax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}
add_action( 'wp_enqueue_scripts', 'delete_post_ajax' );
```
**onClick to pass data to delete method**
in file: /js/my\_script.js
```
jQuery( document ).ready( function($) {
$(document).on( 'click', '.delete-post', function() {
var id = $(this).data('id');
var nonce = $(this).data('nonce');
var post = $(this).parents('.post:first');
$.ajax({
type: 'post',
url: TheAjax.ajaxurl,
data: {
action: 'wpse_ajax_delete_post',
nonce: nonce,
id: id
},
success: function( result ) {
if( result == 'success' ) {
post.fadeOut( function(){
post.remove();
});
}
}
})
return false;
})
})
```
**the delete method**
in file: functions.php
(the hook we need is just "`wp_ajax`" prepending the name of the `action` in js file)
```
add_action( 'wp_ajax_wpse_ajax_delete_post', 'wpse_ajax_delete_post_func' );
function wpse_ajax_delete_post_func(){
$permission = check_ajax_referer( 'ajax_delete_post_nonce', 'nonce', false );
if( $permission == false ) {
echo 'error';
}
else {
wp_delete_post( $_REQUEST['id'] );
echo 'success';
}
die();
}
```
To do the above by passing uri params:
Change where we swapped out `get_delete_posts_link` for this:
```
<?php if( current_user_can( 'delete_post' ) ) : ?>
<?php $nonce = wp_create_nonce('ajax_delete_post_nonce') ?>
<a href="<?php echo admin_url( 'admin-ajax.php?action=wpse_ajax_delete_post&id=' . get_the_ID() . '&nonce=' . $nonce ) ?>" data-id="<?php the_ID() ?>" data-nonce="<?php echo $nonce ?>" class="delete-post">delete</a>
<?php endif ?>
```
See this for [a more involved walkthrough explaining each step](http://www.vandelaydesign.com/delete-a-wordpress-post-using-ajax/)
---
Ditch `blockusers_init` (aka conditional redirect)
--------------------------------------------------
This sets a redirect on wp-admin if user does not have `manage_options` cap, which is an administrator role. But first it pseudo-hides things and adds a message to user with some css:
**The CSS bit**
in file: *functions.php*
```
add_action('admin_head', 'hide_admin_via_css');
function hide_admin_via_css() {
if (!current_user_can( 'manage_options' )) {
echo '<style>body * {visibility:hidden !important;} body:before {content:"Give it a second...";}
';
}
}
```
**Enqueueing the JS file**
in file: *functions.php*
```
function my_enqueue( $hook ) {
if (!current_user_can( 'manage_options' )) {
wp_enqueue_script( 'my_custom_script', get_template_directory_uri() '/js/block-admin.js' );
}
}
add_action('admin_enqueue_scripts', 'my_enqueue');
```
**Set the JS to just immediately redirect**
file: *theme\_root/js/block-admin.js*
```
window.location.href = "/";
```
**OR a timed redirect**
```
setTimeout(function () {
window.location.href = "/";
}, 2000);
```

With WordPress, is there any way to use my old database to automatically generate pages/posts that could be sorted in this way? | Before getting into [*Importing*](https://codex.wordpress.org/Importing_Content), I would familiarize yourself with both the [standard post type](https://codex.wordpress.org/Post_Types) and [post\_meta](https://codex.wordpress.org/Post_Meta_Data_Section) as well as [custom post types](https://codex.wordpress.org/Post_Types) and [taxonomies](https://codex.wordpress.org/Taxonomies). If your end goal would benefit from the latter, you will save yourself quite a bit of headache utilizing them during the import preparation.
---
If you prefer working with the database directly, a dump/convert/import is always possible, of course. The schematic attached below would answer any questions you'd have there.
Another option, in the vein of the importer, would be to send posts from the old site to the wp-json api endpoints of the wordpress site and handle the migration that way.
As [@Rarst](https://wordpress.stackexchange.com/users/847/rarst) mentioned, there isn't really a shortcut, but as [@Max](https://wordpress.stackexchange.com/users/11761/max-yudin) noted in his comment the Importer can at least assist you in the process on the Wordpress side.
The below just elaborates on and consolidates links for those points.
Using Wordpress Importer ( *Tools > Import* )
---------------------------------------------
There are a multitude of options, (and an even greater multitude of things to consider before using any of them), for importing content into wordpress. **This would be the *safest* method to take.**
You can familiarize yourself with many of them here: [Importing Content into Wordpress](https://codex.wordpress.org/Importing_Content)
Including:
* Blogger
* Drupal
* Excel Spreadsheet/CSV/XML/JSON
* Google Blog Converters
* Joomla
* LiveJournal
* Magento
* Mambo
* Movable Type
* Nucleus CMS
* Plone
* Posterous
* SPIP
* Tumblr
* Twitter
* TypePad
* etc, etc, you get the point
That pages also lists various plugins for importing an export of a previous cms (multiple types listed).
CSV, XML, RSS... any manner really. You will have to create the file it needs to process, of course.
---
Database Dump > Import
----------------------
(*Without knowing any info on the current DB*), you could dump the old DBs *pages* content, and convert it into an sql import.
**Don't even consider this if you don't really know what you're doing, though. You could seriously muck things up.** But a viable option if you're comfortable with it.
I would not consider this a *wordpress* solution, just noting it as an approach.
---
Import Bridge with WP-JSON API
------------------------------
If you still have access to the old DB/site, you could utilize the [wp-json api](https://developer.wordpress.org/rest-api/) by writing something on your end that `posts` to the appropriate endpoint on the wordpress end for each entry in your old DB.
You may normally build this for keeping things in sync, but it could work as a one-time import tool as well.
---
Expanding on this in lieu of OP's additional questions in comments:
First, you will want to bookmark [this resource for dealing with the WP\_REST\_request class](https://developer.wordpress.org/reference/classes/wp_rest_request/)
Assuming we have written a bit of code on the *old site* that grabs the relevant content and puts it into a formatted POST object, and assuming a custom endpoint:
`[Old Site Data ]` POST http to route `http://new-WP-site.com/wp-json/v2/plugin_namespace/v1/posts/`
On the WP end, `/plugin_namespace/v1/posts/` we would create. To make this happen, we first `extend` the `WP_REST_Controller` class.
Then inside our class we register our routes using `register_rest_routes()`.
Something like:
```
public function __construct() {
add_action( 'rest_api_init', array($this, 'register_routes' ) );
}//end __construct
public function register_routes() {
$version = '1';
$namespace = 'plugin_namespace/v' . $version;
$base = 'posts';
register_rest_route( $namespace, '/'. $base, array(
array(
'methods' => 'GET',
'callback' => array( $this, 'this_is_a_callback_function' ),
//'permission_callback' => array( $this, 'key_permissions_check' ),
),
array(
'methods' => 'POST',
'callback' => array( $this, 'this_is_a_callback_function' ),
//'permission_callback' => array( $this, 'key_permissions_check' ),
),)
);
}//register_routes
public function this_is_a_callback_function(WP_REST_Request $request) {
//if posted in body like form data
$posted_data = $request->get_body_params();
}
```
From this point `$posted_data` has what was `POST`ed, and you can walk through it, or pass it on to another function that does.
That function would need to build the post\_array out of each entry, and pass that along to `wp_insert_post()`
An approach could be made utilizing `WP_REST_Server::CREATABLE` in place of `methods => POST` as well. Mine is just a quick/incomplete example.
Also I commented out the `permissions_callbacks`, but that callback function is where your authorization checks would normally go.
*Note that `wp_insert_post()` will allow you to pass an array of meta as well, but `wp_update_post` will not. `wp_insert_post` also requires a `title` and `content` values. If you pass any ID other than 0, it will run `wp_upate_post`.*
You may want to look at using something like [requestb.in](https://requestb.in) while sorting out your *old site* code to check what it is sending, and [postman](https://www.getpostman.com/) works quite well for checking the api's response.
As I mentioned in the comments, [ngrok](https://ngrok.com/) could be used to do the non-wp to wp migration completely in a dev environment.
Hopefully that gives you enough info to translate it to whomever you need.
---
Relevant WP Tables (posts)
--------------------------
Whether building an sql import or writing some other bridge,
for **posts**, the tables to map to on the wordpress end of things would be:
>
> **Table Name** : **data in table**
>
>
> wp\_posts : the posts
>
>
> wp\_postmeta : post meta values
>
>
> wp\_term\_relationships : posts to taxonomies
>
>
> wp\_term\_taxonomy : taxonomies
>
>
> wp\_terms : tag and category values
>
>
>

] | I need to know how to write function for registering `activation_hook` and `deactivation_hook` following **OOP fashion with best practices**.
I know there are some tasks we can do inside plugin activation/deactivation which is really essential in some cases like to create professional plugins.
Thanks. | It can be demonstrated like this way:
**Step-1:** Create a folder named *`includes`* (or any name you like) inside the plugin root folder. Create two new files named `class-responsive-slider-activator.php` and `class-responsive-slider-deactivator.php`
Now, in *class-responsive-slider-activator.php* create a class -
```
class Responsive_Slider_Activator {
public static function activate() {
//do your codes to execute upon activation
}
}
```
and in *class-responsive-slider-deactivator.php* create another class-
```
class Responsive_Slider_Deactivator {
public static function deactivate() {
//do your codes to execute upon deactivation
}
}
```
**Step-2:** In main plugin file create functions and register the two hooks -
```
// this code runs during plugin activation
function activate_responsive_slider() {
require_once plugin_dir_path( __FILE__ ) . 'includes/class-responsive-slider-activator.php';
Responsive_Slider_Activator::activate();
}
register_activation_hook( __FILE__, 'activate_responsive_slider' );
// this code runs during plugin deactivation
function deactivate_responsive_slider() {
require_once plugin_dir_path( __FILE__ ) . 'includes/class-responsive-slider-deactivator.php';
Responsive_Slider_Deactivator::activate();
}
register_deactivation_hook( __FILE__, 'deactivate_responsive_slider' );
```
That's it.
N.B. - As per your interest, I would like to denote that there are *some essential tasks* which can be accomplished through activation and deactivation hooks like:
1. Validating other dependent plugin on activation.
2. Creating custom database tables on activation to store data and removing tables on deactivation.
3. Creating custom options for plugins in activation and reset in deactivation.
4. Any other necessary task need to execute in activation. etc |
269,037 | <p>I'm very new to WP theming and I know there are several types of functions to add Widget areas.</p>
<p>The following one, for example, adds a widget area dedicated for menus:</p>
<pre><code># functions.php (register a new widget area):
function newMenuWidgetArea() {
register_nav_menus(
array (
'my-custom-menu' => __('newMenu'),
'extra-menu' => __('newMenu')

}
add_action('init', 'newMenuWidgetArea');

);
?>
</code></pre>
<h2>The problem:</h2>
<p>I don't want to add custom menus manually for example, so I don't look for a functions that add menus and their widget areas manually.</p>
<p>I wish to add menus from the GUI, hence I am looking forward to use a function that create global widget areas that can serve for any purpose, and then I will add into them anything I wish directly from the GUI (menu, text area, or whatever other widget).</p>
<h2>The question:</h2>
<p>What is the general function to add a general-purpose/multi-purpose Widget area?</p>
<p>The one I have for now creates a menu. not a widget area in which I could place widgets.</p>

The first problem is an *error*, which was raised in your AJAX call. The reason you do not get to see the error directly is, that —and this is what defines AJAX, the *A* is for *asyncronous*— the error was not in your current request, but in a request *spawned* by your current request, which ran in its own process in the background. Meaning: You will have to inspect the AJAX callback, the functionality that was called, to find the actual error.
Chrome has a nice set of debugging options available:
1. You can replay that request without loading the whole page again, without repeating the process (e.g. opening a modal) and without bringing the request to a specific state. If you have a callback failing and are in local dev mode, simply change your AJAX endpoint handler, the callback script, hit *Replay XHR* and you will execute the callback with the changed code. Logical? Yes! Overseen? Yes, often.
2. You can open any script that runs in the background, during an AJAX request, in a separate tab. That often makes error messages visible as they printed to the screen. Same here: Easy solution, but overseen by most devs.
The second problem is a [race condition](https://en.wikipedia.org/wiki/Race_condition), a *timing* issue. A good indicator for a race condition is using a *slow* connection, something that you can for e.g. set and test in the Chrome developer tools. When things go slow, it's easier to notice and watch when one script finishes its task earlier than another one that relies on the result. If the result is not available, it will fail. When WordPress tells you, that you enqueued a script too early, then for the reason that some script, shipped with core and noted as a dependency, is not yet ready. Another thing that is noted there is that you enqueued the script before the *Dependency API* is not yet ready to *accept* enqueuing a new script. This means that WP will not take and load and output your script, making WP fail at this point.

Possible? | Here's a solution that will remove the original author meta box and replace it with a similar, but customized version which includes users with the `contributor` role.
The logic for adding/removing the author meta box is pulled directly from the core. The meta box display callback is also cloned from the core, but we use the `role__in` parameter of [`wp_dropdown_users()`](https://developer.wordpress.org/reference/functions/wp_dropdown_users/) which lets us specify which roles we want to include within the dropdown.
```
/**

remove_meta_box( 'authordiv', $post_type, 'core' );
add_meta_box( 'authordiv', __( 'Author', 'text-domain' ), 'wpse_post_author_meta_box', null, 'normal' );
}
}
}
/**

``` | For anyone else finding this question. Wordpress seems to do a `SHOW FULL COLUMNS` query before executing the `INSERT` query. If it determines that the `INSERT` query would fail/store bad data, for example because the given data types would not fit in the column, it does not execute the insert query at all and return false.
Check:
* Have you filled all fields that can not be null and do not have a default value
* Does the data type for every field match the data type in the database
* Does the data passed to the function violate any constraints? A string cannot be longer than the maximum length of the field you are trying to put it into. An integer field has a minimum and maximum value. Unsigned integers cannot contain negative values. |

How can I make navigation like one in blazok theme on themeforest. | Download [Bootstrap nav walker file](https://drive.google.com/open?id=0B1mlr5jLh4p8TEFya1JsQmQzWW8).Call this file to your functions.php. Then Put this code to dynamic your nav menu:
```
<?php
$args = array(
'theme_location' => 'primary',
'menu' => 'Main',
'container' => 'false',
'container_class' => '',
'container_id' => '',

269,267 | <p>I am using a plugin called AddThis on a website at: <a href="http://minionsphotography.com/" rel="nofollow noreferrer">http://minionsphotography.com/</a>. With AddThis enabled I am getting some extra P tags in-between the header and the text on the page: <code><p><!-- AddThis Sharing Buttons above --></p></code>, this adds a lot of extra space and shouldn't be there. *On the homepage it's the space between the Welcome header and the slideshow image.</p>
<p>Is there a function or something out there that I could use to find and remove the html comment on the page to eliminate the extra space? I use a plugin called pSquirrel to detect and remove empty P tags, but it won't remove this one (I'm guessing because pSquirrel doesn't think it's empty because of the html comment).</p>

] | I am using a plugin called AddThis on a website at: <http://minionsphotography.com/>. With AddThis enabled I am getting some extra P tags in-between the header and the text on the page: `<p><!-- AddThis Sharing Buttons above --></p>`, this adds a lot of extra space and shouldn't be there. \*On the homepage it's the space between the Welcome header and the slideshow image.
Is there a function or something out there that I could use to find and remove the html comment on the page to eliminate the extra space? I use a plugin called pSquirrel to detect and remove empty P tags, but it won't remove this one (I'm guessing because pSquirrel doesn't think it's empty because of the html comment).
Thanks,

Note that this is different from `password_change_email` which you've used in your original code. That filter allows you to modify the e-mail sent to the user when their *password* is changed.
These two filters work similarly but it's important to make a distinction between the two. Both filters appear in `wp-includes/user.php`.
* In the code below, we use the `email_change_email` to modify the message text. The new placeholders, `###FIRST_NAME###` and `###LAST_NAME###` have been added to the code (and docs) below.
* The standard placeholders wherever possible in the message text, instead of hardcoding the strings.
* Also, a text domain was added to the customized message text. It's always a good practice to add a text domain to strings that are passed to gettext functions ( `__()`, `_e()`, etc.).

Please let me know if some other code is needed. | Check out the markup. On the search results page, the `<body>` element is assigned the classes `search` and `search-no-results`.
```
<body class="search search-no-results">
```
Looking at the CSS, the styles for `.search` are intended to be used for the search input. They are working for that, but they are also being applied to the body due to the use of a weak selector:
```
.search {
border: 1px solid #CCCCCC;
padding: 5px 7px;
/*margin-left: 15px;*/
width: 175px;
-webkit-transition: all .5s ease;
-moz-transition: all .5s ease;
transition: all .5s ease;
/*position: absolute;*/
right: 0;
/*float: right;*/
}
```
That's no good. I'd update the selector to be more specific:
```
input.search {
...
}

How can I change the wp-login.php page `<title>`? | It looks like it's not easily accessible as it's displayed as [src](https://github.com/WordPress/WordPress/blob/1d34043e8cd2eead37048bc8aed379d57ff32408/wp-login.php#L69):
```
<title><?php echo get_bloginfo( 'name', 'display' ) . $separator . $title; ?></title>

where the separator is:
```
$separator = is_rtl() ? ' › ' : ' ‹ ';
```
and the `$title` part comes from:
```
login_header( $title = 'Some title' , ... );
```
But it looks like you've already checked this out, as I see you've filed a ticket [#40812](https://core.trac.wordpress.org/ticket/40812) for an extra filter to change the *separator*.
A workaround that comes to mind, to change the *separator*, would be to use *output buffering* hacks to replace it. |

I know I can enter a title and then remove all titles with CSS, but I want to display some titles.
I feel there is a way | It looks like the suggestion by @DaveRomsey will solve the problem.
Another simple idea is from a [plugin](https://wordpress.org/plugins/remove-widget-titles/) by [Stephen Cronin](https://profiles.wordpress.org/stephencronin), (*I'm not related to that plugin in any way.*) that uses the `widget_title` filter:
```
add_filter( 'widget_title', function( $title )
{
return '!' === mb_substr ( $title, 0, 1 ) ? '' : $title;
} );
```
where I've adjusted the code a little bit.
It simply removes the widget's title if it starts with `!`.
This is handy for e.g. Text Widgets containing ads where we don't want the widget's title to display on the front-end. This approach makes it easier to manage the widgets as we can still see their titles in the backend.
Hope it helps! |

This means that `orderby` and `order` are valid arguments for your query.
When you ask, "*how i get them with the order as i needed*", is the property you wish to order them by a [valid `orderby` value](https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters)? If so, your function call might look like this:
```
$post_images = get_children( array(
'post_parent' => $id,
'post_status' => 'inherit',
'post_type' => 'attachment',
'post_mime_type' => 'image',
'orderby' => 'title'

This is NOT a PHP file, so no:

Or? | You can output your javascript via `wp_add_inline_script()`. This way you can set the post's id and AJAX URL before outputting the code:

wp_add_inline_script('my-js', '

Is there any way I can achieve this? | You don't have to write a new plugin. You can either add the code to your theme's `functions.php` file, or create a [child theme](https://codex.wordpress.org/Child_Themes).
To wrap your data in a JSON format, you can use the `json_encode` function. Hook into the post when it's published, and send the data. In the following function, i will send the post's title, excerpt and featured image URL to the endpoint.
```
add_action('publish_post', 'call_the_endpoint',10,2);
function call_the_endpoint($post_id, $post){
// Define an empty array
$data = array();
// Store the title into the array
$data['title'] = get_the_title();
// If there is a post thumbnail, get the link
if (has_post_thumbnail()) {
$data['thumbnail'] = get_the_post_thumbnail_url( get_the_ID(),'thumbnail' );
}
// Get the excerpt and save it into the array
$data['excerpt'] = get_the_excerpt();
// Encode the data to be sent
$json_data = json_encode($data);
// Initiate the cURL
$url = curl_init('YOUR API URL HERE');
curl_setopt($url, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($url, CURLOPT_POSTFIELDS, $json_data);
curl_setopt($url, CURLOPT_RETURNTRANSFER, true);
curl_setopt($url, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($json_data))
);
// The results of our request, to use later if we want.
$result = curl_exec($url);
}
```
It would be possible to write an accurate answer if you could provide more information about your API and how you interact with it. However this was a simple example for you to know how to use the `publish_post` hook to achieve what you are looking for. |

] | How can I retrieve the values passed to the shortcode using only one parameter?
Example:
```
[related type="2,3,4,5,6"]
```
Is it possible to do that? | The solution below will parse the comma separated values passed to the shortcode's `type` parameter. We'll also strip out any whitespace surrounding the values which is a usability improvement (see example 2 after the code below).
```
add_shortcode( 'related', 'wpse_related' );
function wpse_related( $atts, $content = '' ) {
// User provided values are stored in $atts.
// Default values are passed to shortcode_atts() below.
// Merged values are stored in the $a array.
$a = shortcode_atts( [
'type' => false,
], $atts );
$output = '';
if ( $a['type'] ) {
// Parse type into an array. Whitespace will be stripped.
$a['type'] = array_map( 'trim', str_getcsv( $a['type'], ',' ) );
}
// Debugging: Display the type parameter as a formatted array.
$output .= '<pre>' . print_r( $a['type'], true ) . '</pre>';
return $output;
}
```
**Example 1:**
```
[related type="2,3,4,5,6"]
```
**Output:**
```
Array
(
[0] => 2
[1] => 3
[2] => 4
[3] => 5
[4] => 6
)
```
**Example 2:**
```
[related type="8, 6, 7,5,30, 9"]
```
**Output:**
```
Array
(
[0] => 8
[1] => 6
[2] => 7
[3] => 5
[4] => 30
[5] => 9
)

] | I would like to update a post on every new comment, so that the `Last Modified Date` is always up to date on the sitemap.
How can i do this?
Thanks. | From what i understand, you want to change the post's modification time whenever a comment is left on your post. For this, you need to hook into the `wp_insert_comment` hook and update the post's date manually:
```
add_action('wp_insert_comment','update_post_time',99,2);
function update_post_time($comment_id, $comment_object) {
// Get the post's ID
$post_id = $comment_object->comment_post_ID;
// Double check for post's ID, since this value is mandatory in wp_update_post()
if ($post_id) {
// Get the current time
$time = current_time('mysql');
// Form an array of data to be updated
$post_data = array(
'ID' => $post_id,
'post_modified' => $time,
'post_modified_gmt' => get_gmt_from_date( $time )
);
// Update the post
wp_update_post( $post_data );
}
}
```
Note that this will create a revision for the post each time a comment is created.
If your sitemap plugin uses the `post_date` instead of `post_modified`, you can use this instead:
```
$post_data = array(
'ID' => $post_id,
'post_date' => $time,
'post_date_gmt' => get_gmt_from_date( $time )
);
```
However, this might cause problems, and mess post's order in archives and homepage, since it changes the post's **creation** date, not modification date. |

I don't need or want the visual editor in widgets; I use them for plain text and html and don't need other users adding anything other than plain text.
I did learn how to *remove* the new video, audio and image widgets in `functions.php` as I don't need them:

unregister_widget('WP_Widget_Media_Audio' );
unregister_widget('WP_Widget_Media_Image');

}

```
But I also want to remove the visual editor tab from the default text widget.
**Edit:** I can use the PHP Code Widget <https://wordpress.org/plugins/php-code-widget/> which does not have the visual editor, and though I don't usually need `php` execution, it is useful. But this adds the "break things" vector for users who might play with `php`. | The answer is mostly no. The "enhanced" text widget was designed to work like the post editor as much as possible, including autop which might break whatever HTML that can not stand the conversion of lines into paragraphs.
Several people have released plugins to restore the former functionality, but 4.8.1 will also include an "code" widget that can be used to add unaltered HTML. The problem is that there is no, and unlikely to be a plain upgrade path. Best advice right now if you use the html widget is to skip 4.8 and wait for 4.8.1 and allocate some time in advance to migrate the widgets.
If you are just looking to hide the "visual" tab, you are most like also out of luck best to open a ticket at trac to add such possibility, specifically for the widget without impact on the post editor (4.8.1 plan right now is to use the same setting for both) |

Similar to the below function (for removing version numbers), but I'd like to add version numbers.
```
function _remove_script_version($src) {
return $src ? esc_url(remove_query_arg('ver', $src)) : false;
}
add_filter('style_loader_src', '_remove_script_version', 15, 1);
add_filter('script_loader_src', '_remove_script_version', 15, 1);
``` | You could use [add\_query\_arg()](http://developer.wordpress.org/reference/functions/add_query_arg) but then you'd have to parse the uri everytime, I'd rather create a wrapper function for wp\_enqueue\_script/style:
```
function my_enqueuer($my_handle, $relpath, $type='script', $my_deps=array()) {
$uri = get_theme_file_uri($relpath);
$vsn = filemtime(get_theme_file_path($relpath));
if($type == 'script') wp_enqueue_script($my_handle, $uri, $my_deps, $vsn);
else if($type == 'style') wp_enqueue_style($my_handle, $uri, $my_deps, $vsn);
}
```
Add this in your functions file and then in place of e.g.
```
wp_enqueue_script('_base', get_theme_file_uri('/assets/js/base.js'), array(), filemtime(get_theme_file_path('/assets/js/base.js')));
```
call:
```
my_enqueuer('_base', '/assets/js/base.js');
```
and in place of e.g.
```
wp_enqueue_style('_base', get_theme_file_uri('/assets/css/base.css'), array(), filemtime(get_theme_file_path('/assets/css/base.css')));
```
call:
```
my_enqueuer('_base', '/assets/css/base.css', 'style');
```
You can pass the dependency array as the last argument when needed. For scripts, if you pass the dependency array, you will have to pass the third parameter 'script' as well, even though I've set it as the default value. |

Problem
-------
I can reach the admin dashboard page, however I cannot go further as the link becomes `http://example.com/wp-admin` instead of `http://example.com/hello/wp-admin`. How could I get rid of this weird behaviour?
Details that might help...
--------------------------
1. I am quite sure that the WordPress Address (URL) and Site Address (URL) are configured as `http://example.com/hello`, I even checked the database table `wp_options`.
2. When it arrives the admin dashboard page with correct CSS, the browser will show the correct link for half seconds and suddenly change to the wrong one. I even checked the network log in my Chrome and Firefox, the requested URL is `http://example.com/hello/wp-admin`.
3. I have tried to configure the `.htaccess` as well, but no luck.
```
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /hello
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /hello/index.php [L]
</IfModule>
# END WordPress
``` | Eventually, I found the reason of this weird behaviour.
It is caused by the JavaScript embedded in `wp_admin_canonical_url()` (<https://developer.wordpress.org/reference/functions/wp_admin_canonical_url/>)
The URL is determined by this piece of code
```
$_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']
```
where the latter one returns `wp-admin` instead of `hello/wp-admin`.
By manipulating the value in `$_SERVER['REQUEST_URI']`, I can successfully get the correct behaviour in admin dashboard. But I still hope for an elegant solution without touching WordPress code. |

I have the two ideas:

2. Do not use wp\_editor() at all but use textareas and apply TinyMCE to them dynamically. Problems: File Upload will be missing. How to apply TinyMCE scripts on every new widget/widget load?
Tried a lot of things so far but no luck. | It's hard to say without seeing *all* the code.
Yes if you don't refer to the instance - then it won't really be a unique ID. Something like this would work - you would just reference the class property $id:
```
for ( $i = 0; $i <= count( $suffixes ); $i++) {
wp_editor( 'your content', "{$this->id}_$i" );
}
```
The js in core for the text widget create a random ID for the editor instances before it handles the instantiation, so you could translate that over to PHP if you wanted to follow that:
```
$el = 'el' . preg_replace( '/\D/', '', ( rand()/getrandmax() ) ) . '_';
```
Since your developing locally - you should turn on SCRIPT\_DEBUG in your wp-config.php: define( 'SCRIPT\_DEBUG', true ); to help you troubleshoot your issues with javascript. Doing so would make that error from minified files be a little more meaningful. The error is being caused by switchEditor method in editor.min.js. There's special handling of the tinymce text widget in the customizer - and it's not just as simple as calling wp\_editor - though it could probably be done. You could try enabling the wp\_skip\_init process and adding your own initialization code perhaps:
```
add_filter( 'wp_editor_settings', 'ciseditor_wp_editor_settings', 5, 2 );
function ciseditor_wp_editor_settings( $settings, $id ) {
// look for your prefixed id and return the id associated with it.
if ( $ed = strstr( $id, 'foo_widget' ) ) {
$settings['tinymce'] = array(
'wp_skip_init' => true,
'wp_autoresize_on' => false, // turn off the auto resize height of editor.
);
$settings['editor_height'] = 300; // set the height
}
return $settings;
}
```
I'm pretty sure that won't be the way to go though. I would recommend looking at wp-admin/js/text-widgets.js to see the handling of how core is implementing the text widget and the switch editor functionality - along with properly handling the data for the customizer. You should also reference wp-includes/widgets/class-wp-widget-text.php since you're essentially wanting to make the same thing that already exists.
Generally having that error in tinymce means that the instance isn't being removed and added back properly - so it makes sense that WordPress' switchEditor in this context is throwing errors for you. There's a lot of documentation in the text-widgets.js about how tinymce and dynamic DOM components will interact that have to be accounted for or you'll end up with issues.
One quick solution might just be to disable quicktags for your editor instances, which could be done in the wp\_editor\_settings filter or you can also pass it in the settings array when you're making the editors, ie:
```
wp_editor( 'your content', "{$this->id}_$i", array( 'quicktags' => false ) );
```
I did dynamically create tinymce instances on a project once in wordpress, and I just remember looking at the editor code in core to see what arguments and scripts they included to get everything working, so that's always an option too. If you go that route - most of the things translate over 1:1 in terms of the php abstraction to js for the params. I think for the add media button I ended up creating my own thing, but there is the action 'media\_buttons' so you should be able to just add that where it needs to be displayed.
Also consider why it is that you need multiple editors in one widget. Another way to handle this would be to remove the instances in an accordion style within the widget itself, and rebuild them as accordions are expanded so only one widget is displayed at a time. I think ultimately though - having one editor in a widget suits most use cases, and gives the end user flexibility to move content where they find it most fitting for their own use. |

] | How to set custom title of custom page template?
I try use `wp_title` filter but it's not working. | [Reference](https://wordpress.stackexchange.com/questions/62415/changing-document-title-only-on-a-custom-page-template/62417?newreg=9e9601805cd5461e9ab988dc3e605854)
Got success by adding this code to `your-page-template.php` file before `get_header()` function:
```
function my_page_title() {
return 'Your value is '; // add dynamic content to this title (if needed)
}
add_action( 'pre_get_document_title', 'my_page_title' );

The odd thing is, all the image URLs are correct in the source code of blogs. But in my media library, they are all missing .co.uk.
How do I add .co.uk back into my media library URLs? | As mentioned in the comments under your question, some data in the WordPress database is serialized and therefore not possible to change with a simple find and replace.
You should read through the [Moving WordPress](https://codex.wordpress.org/Moving_WordPress) section of the codex. Specifically the [Changing Your Domain Name and URLs](https://codex.wordpress.org/Moving_WordPress#Changing_Your_Domain_Name_and_URLs) portion. I usually use a plugin or a command line tool depending on what's available to me.
### Plugin:
[Better Search Replace](https://wordpress.org/plugins/better-search-replace/#description) is a useful plugin recommended in the entry above. There are other plugins that will do the same things but this is my preference. Some features that I enjoy are:
* Support for serialized data.
* The ability to select single or multiple tables.
* A "dry run" feature to test and verify your changes before actually performing them.
* Very few server requirements (all you *need* is a WP instance.)
---
### CLI Tool:
Another option that handles serialized data is the [WP-CLI's search-replace tool](https://developer.wordpress.org/cli/commands/search-replace/). This option is used from the command line via something like SSH and requires the wp-cli to be installed on the server. You can [take a look at the docs](https://developer.wordpress.org/cli/commands/search-replace/) for all available options and examples but the basic usage is:
```
# Search for old domain name and replace it with a new one
$ wp search-replace 'http://old.example.dev' 'http://new.example.com'

How can I re-target these assets so it finds them in the parent theme? I don't want to have to re-import assets to the child theme every time I update Wordpress... | There is most likely some issues about using [`get_template_directory_uri()`](https://developer.wordpress.org/reference/functions/get_template_directory_uri/) or [`get_stylesheet_directory_uri()`](https://codex.wordpress.org/Function_Reference/get_stylesheet_directory_uri).
According to WordPress Code reference:
>
> `get_template_directory_uri()` function returns the URL to the root theme. If a child theme is
> used and you want to return the URL to the current child theme, use

So, what you have to do is to enqueue the style by using the following code in your child theme's functions.php file:
```
add_action( 'wp_enqueue_scripts', 'my_child_theme_styles' );
function my_child_theme_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
```

Am I experiencing a bug? | I had a quick look and here's how the headers are set in the [`WP_REST_Posts_Controller::get_items()`](https://developer.wordpress.org/reference/classes/wp_rest_posts_controller/get_items/) method:
```
$response = rest_ensure_response( $posts );
// ...
$response->header( 'X-WP-Total', (int) $total_posts );
$response->header( 'X-WP-TotalPages', (int) $max_pages );
// ...
return $response;
```
where:
```
$total_posts = $posts_query->found_posts;
```
and we could use as @jshwlkr [suggested](https://wordpress.stackexchange.com/users/98703/jshwlkr):
```
$max_pages = $posts_query->max_num_pages;
```
You could emulate that for your custom endpoint, by using `WP_Query` instead of `get_posts()`.

] | I've read a couple of things about the wp.media object and have successfully initialised in the state that I can find to upload images. But for the plug-in that I am building I need to have the same layout as when I click my attachment in de media grid gallery.
For now this is my "simple" code that opens the default wp.media object
```
// Create a new media frame
frame = wp.media({
title: 'Select or Upload Media Of Your Chosen Persuasion',
button: {
text: 'Use this media'
},
multiple: false // Set to true to allow multiple files to be selected
});
// Finally, open the modal on click
frame.open();
```
What I need is the exact same result as you follow the url down below:
```
http://wordpress.dev/wp-admin/upload.php?item=10
```
Where you need to replace wordpress.dev with your own WP installation en item=10 to any attachment ID you actually have.
It should look like the following screenshot:

] | Running NGINX, Wordpress 4.75 after upgrading from a way older version of Wordpress, our images are being served locally and I would like to change that to our CDN.
In the past images that were uploaded to the blog were uploaded directly to our CDN using a plugin ( I think Offload S3 Lite ).
My goal is that I want post images, thumbnail etc URL to be served from our CDN and not local.

Before the wordpress site (was not updated for a while) was uploading images directly to the CDN (AWS S3 -> Cloudfront) now that we upgraded to 4.75 the images that get served are pointing to local url instead of our CDN url.
images are served through the functions like:
the\_post\_thumbnail()
Which I believe uses wp\_get\_attachment\_image under the hood. If I can included a function in my functions.php to rewrite image urls that could work too.
So how can I get the image urls to point to our CDN and instead of local url?
Thanks for your help! | Since the major adoption of **Responsive Images** and the addition of new `srcset` attribute to the `<img>` element. WordPress has to evolve too. WordPress 4.4 added the responsive images feature.
If you inspect the `src` attribute it might point to the CDN, however, you still need to consider the `srcset` attribute which might still be using the local version of the images.
First, we need to provide the algorithm for changing the local URL to the CDN version. The algorithm I use adheres your test case above; i.e. <https://test.com/> to <https://cdn.test.com/>
### Add these to `functions.php`
```
// Add .cdn after http:// or https://
function to_cdn($src) {
$dslash_pos = strpos($src, '//') + 2;
$src_pre = substr($src, 0, $dslash_pos); // http:// or https://
$src_post = substr($src, $dslash_pos); // The rest after http:// or https://
return $src_pre . 'cdn.' . $src_post;
}
```
Then we need to change the `src` attribute of the image using the [wp\_get\_attachment\_image\_src](https://developer.wordpress.org/reference/hooks/wp_get_attachment_image_src/) filter.
```
function test_get_attachment_image_src($image, $attachment_id, $size, $icon) {
if(!is_admin()) {
if(!image) {
return false;
}
if(is_array($image)) {
$src = to_cdn($image[0]); // To CDN
$width = $image[1];
$height = $image[2];
return [$src, $width, $height, true];
} else {
return false;
}
}
return $image;
}
add_filter('wp_get_attachment_image_src', 'test_get_attachment_image_src', 10, 4);
```
Next is for the `srcset` attribute this time using [wp\_calculate\_image\_srcset](https://developer.wordpress.org/reference/hooks/wp_calculate_image_srcset/) filter.
```
function test_calculate_image_srcset($sources, $size_array, $image_src, $image_meta, $attachment_id) {
if(!is_admin()) {
$images = [];
foreach($sources as $source) {
$src = to_cdn($source['url']); // To CDN
$images[] = [
'url' => $src,
'descriptor' => $source['descriptor'],
'value' => $source['value']
];
}
return $images;
}
return $sources;
}
add_filter('wp_calculate_image_srcset', 'test_calculate_image_srcset', 10, 5);

If I try to go to example.com/slide/something/ I am *redirected* to the homepage. | Two problems I see- rewrite rules need to set query vars that will result in a successful main query. Setting just a custom var like `slide` doesn't parse to anything WordPress can load. Additionally, `slide` needs to be [added to the recognized query vars](https://codex.wordpress.org/Plugin_API/Filter_Reference/query_vars) for it to get parsed within a rule.
So, what would a rule look like that would load the front page posts in the main query? That's a good question- the posts page is a special case, the absence of any other query vars. I haven't found a way to do that with a rule, though it may exist.
An easier way to do this is with a rewrite endpoint:
```
function wpd_slide_endpoint(){
add_rewrite_endpoint( 'slide', EP_ROOT );
}
add_action( 'init', 'wpd_slide_endpoint' );
```
Keep in mind that if you have code accessing values via `$_GET`, this still won't work, because WordPress doesn't put query vars there when rules are parsed. You can change the code to use `get_query_var`, or just assign it before the code tries to access it:
```
$_GET['slide'] = get_query_var('slide');

<a href='<?php echo esc_url( get_permalink( get_option( 'page_for_posts' ) ) ); ?>' title='<?php echo esc_attr( get_bloginfo( 'title' ) ); ?>' rel='home'>Blog Page</a>
```
The above will grab `page_for_posts` value from the options table which holds the Page ID of the blog which needs to be set in `Settings -> Readings`. By passing an ID to `get_permalink()` it will return the string URL that we need for the page. |

270,235 | <p>I'm trying to make booking - plugin with form on WordPress-admin site, where I can add new event in calendar (made with JavaScript).
I have to submit form with all data and insert data to MySQL Database.</p>
<p>My <strong>ajax.js</strong> file:</p>
<pre><code>function ajaxSubmit(e){
var nazwa_szkolenia = document.getElementById("nazwa_szkolenia").value;
var Data_szkolenia = document.getElementById("Data_szkolenia").value;
var Godzina = document.getElementById("Godzina").value;
var Max_pacjent = document.getElementById("Max_pacjent").value;
// Returns successful data submission message when the entered information is stored in database.
var dataString = 'nazwa_szkolenia1=' + nazwa_szkolenia + '&Data_szkolenia1=' + Data_szkolenia + '&Godzina1=' + Godzina + '&Max_pacjent1=' + Max_pacjent;
if (nazwa_szkolenia == '' || Data_szkolenia == '' || Max_pacjent == '') {
alert("fill all fields");
} else {
// prevent the default action.
e.preventDefault();
var myform= jQuery(this).serialize();
jQuery.ajax({
type:"POST",
// Get the admin ajax url which we have passed through wp_localize_script().
url: ajax_object.ajax_url,
action: "submitAjaxForm",
data: dataString,
error: function(jqXHR, textStatus, errorThrown){
console.error("The following error occurred: " + textStatus, errorThrown);
},
success:function(data){
alert("process OK");
}
});
}
return false;
}
</code></pre>
<p><strong>arcode-functions.php</strong>:</p>
<pre><code><?php
add_action('init', 'registerFormAction');
function registerFormAction(){
add_action('wp_ajax_nopriv_submitAjaxForm','submitAjaxForm_callback');
add_action('wp_ajax_submitAjaxForm','submitAjaxForm_callback');
}
function submitAjaxForm_callback(){
global $wpdb;
$nazwa_szkolenia2 = $_POST['nazwa_szkolenia1'];
$Data_szkolenia2 = $_POST['Data_szkolenia1'];
$Godzina2 = $_POST['Godzina1'];
$Max_pacjent2 = $_POST['Max_pacjent1'];

wp_die();
}
?>
</code></pre>
<p>I've added <code>admin-ajax.php</code> with <code>wp_localize_script</code> function. The form button is made with JavaScript:</p>
<pre><code>var Input_Form_Send = document.createElement('input');
Input_Form_Send.value = 'Utwórz';
Input_Form_Send.type = 'submit';
Input_Form_Send.className = 'input-form-send';
Input_Form_Send.onclick = ajaxSubmit;
</code></pre>
<p>When I fill all fields from form, click on the button, then comes alert "process ok", but on the Database comes nothing new... <em>nazwa_szkolenia</em>, <em>Data_szkolenia</em>, <em>Godzina</em>, <em>Max_pacjent</em> -those are the names of the form fields.</p>
<p>Maybe you know what I've made wrong?</p>

Has anyone an idea? | I found it at last!
Using the browser debugger, I found that there was a "editor.wp" which was undefined (in the complete version of the js file).
Then I understood that the "wordpress" plugin was not used in the editor.
When calling the function wp\_editor, I was setting a list of plugin : paste, wplink, textcolor.
It was working until a specific WordPress update.
I just had to add the "wordpress" plugin in the list, and now it's working. |
