259,657 | <p>I'm building a plugin using the <a href="https://github.com/DevinVinson/WordPress-Plugin-Boilerplate" rel="nofollow noreferrer">WordPress Plugin Boilerplate by DevinVinson</a>.</p>
<p>Everything works fine, except one thing:</p>
<p>I'm trying to enqueue scripts and css only when a shortcode is present in the page. </p>
<p>In <code>define_public_hooks</code> function, I added a call to the loader to register scripts instead of enqueuing them:</p>
<pre><code>private function define_public_hooks() {
// ...
$this->loader->add_action( 'wp_register_script', $plugin_public, 'register_styles' );
$this->loader->add_action( 'wp_register_script', $plugin_public, 'register_scripts' );
// ...
}
</code></pre>
<p>Then in <code>class-my-plugin-public.php</code> file I created two public functions <code>register_styles()</code> and <code>register_scripts()</code>. Inside these functions, I just register scripts and styles, instead of enqueuing them. It's something basic, like this:</p>
<pre><code>public function register_scripts() {
wp_register_script( $this->plugin_name . '_google_maps_api', '//maps.googleapis.com/maps/api/js?key='. $gmap_key .'&amp;v=3&amp;libraries=places', array( 'jquery' ), '3', true );
}
</code></pre>
<p>Then I would like to enqueue them in the shortcode return function, but they do not get registered at all.</p>
<p>I checked with <code>wp_script_is( $this->plugin_name . '_google_maps_api', 'registered' )</code>, and it returns <code>false</code>.</p>
<p>If I make the very same stuff, but with <code>enqueue</code> instead of <code>register</code> everything works fine.</p>
<p>Any idea why?</p>

"text": "<p>So the problem is that the first argument to the <code>add_action</code> call needs to be a <em>WordPress</em> action name... So \"wp_register_script\", not being a WP action, is never called.</p>\n\n<p>I'd suggest all you need to do, really, is add your registering calls to your plugin's enqueue_scripts function - no need to fuss with the define_public_hooks, or create a new register_scripts function. Simply go with the existing enqueue_scripts function, but add your registrations there:</p>\n\n<pre><code>public function enqueue_scripts() {\n wp_enqueue_script( $this->plugin_name, plugin_dir_url( __FILE__ ) . 'js/plugin-name-public.js', array( 'jquery' ), $this->version, false );\n\n // NOTICE this is a *registration* only:\n wp_register_script( $this->plugin_name.'_google_maps_api', '//maps.googleapis.com/maps/api/js?key='. $gmap_key.'&amp;v=3&amp;libraries=places', array( 'jquery' ), '3', true ); \n}\n</code></pre>\n\n<p>Then when your short code, your script should be registered, ready to be enqueued.</p>\n\n<p>Hope this helps!</p>\n"

| I'm building a plugin using the [WordPress Plugin Boilerplate by DevinVinson](https://github.com/DevinVinson/WordPress-Plugin-Boilerplate).
Everything works fine, except one thing:
I'm trying to enqueue scripts and css only when a shortcode is present in the page.
In `define_public_hooks` function, I added a call to the loader to register scripts instead of enqueuing them:
```
private function define_public_hooks() {
// ...
$this->loader->add_action( 'wp_register_script', $plugin_public, 'register_styles' );
$this->loader->add_action( 'wp_register_script', $plugin_public, 'register_scripts' );
// ...
}
```
Then in `class-my-plugin-public.php` file I created two public functions `register_styles()` and `register_scripts()`. Inside these functions, I just register scripts and styles, instead of enqueuing them. It's something basic, like this:
```
public function register_scripts() {
wp_register_script( $this->plugin_name . '_google_maps_api', '//maps.googleapis.com/maps/api/js?key='. $gmap_key .'&v=3&libraries=places', array( 'jquery' ), '3', true );
}
```
Then I would like to enqueue them in the shortcode return function, but they do not get registered at all.
I checked with `wp_script_is( $this->plugin_name . '_google_maps_api', 'registered' )`, and it returns `false`.
If I make the very same stuff, but with `enqueue` instead of `register` everything works fine.
Any idea why? | Why it's not working:
=====================
You need to use the [`wp_enqueue_scripts`](https://developer.wordpress.org/reference/hooks/wp_enqueue_scripts/) action hook. You've used `wp_register_script` as an action hook, however, there is no action hook named `wp_register_script` in WordPress core.
If this was just a silly mistake, then you already have the answer. Read on if you need more information regarding the topic:
---
Attaching a callback function to [`wp_enqueue_scripts`](https://developer.wordpress.org/reference/hooks/wp_enqueue_scripts/) [action hook](https://developer.wordpress.org/plugins/hooks/actions/) doesn't mean your scripts and styles will be enqueued, it simply means when you want to execute that [callback function](http://php.net/manual/en/language.types.callable.php).
The original registering and enqueuing is done by functions such as: `wp_register_script()`, `wp_register_style`, `wp_enqueue_script()`, `wp_enqueue_style()` etc., not by any [hook](https://developer.wordpress.org/plugins/hooks/).
>
> Note the difference between the role of functions and hooks:
>
>
> * A [**function**](http://php.net/manual/en/functions.user-defined.php) executes some CODE to accomplish predefined tasks when called.
>
>
> Example: these all are WordPress core functions: `wp_register_script()`, `wp_register_style`, `wp_enqueue_script()`, `wp_enqueue_style()`.
> * A [**hook**](https://developer.wordpress.org/plugins/hooks/) only attaches a [callable](http://php.net/manual/en/function.is-callable.php) function (to be executed later) at a predefined point of CODE execution.
>
>
> Example: this is a WordPress core (action) hook: `wp_enqueue_scripts` - notice the `s` (plural) at the end.
>
>
> ***Double check:*** `wp_enqueue_script()` is a function and `wp_enqueue_scripts` is an action hook.
>
>
>
The correct CODE:
=================
So your corrected CODE should be like:
```
private function define_public_hooks() {
// ...
$this->loader->add_action( 'wp_enqueue_scripts', $plugin_public, 'register_styles' );
$this->loader->add_action( 'wp_enqueue_scripts', $plugin_public, 'register_scripts' );
// ...
}
```
Then,
```
public function register_scripts() {
wp_register_script( $this->plugin_name . '_google_maps_api', '//maps.googleapis.com/maps/api/js?key='. $gmap_key.'&v=3&libraries=places', array( 'jquery' ), '3', true );
}
```
After that, you enqueue the script (& style) from within you shortcode handler function:
```
public function your_shortcode_handler( $atts ) {
// shortcode related CODE
wp_enqueue_script( $this->plugin_name . '_google_maps_api' );
// more shortcode related CODE
}
```
With this CODE, your scripts / styles enqueued from `your_shortcode_handler` function will only be added to your site when there is a shortcode in that particular URL.

Does anyone have any suggestions/insight/advice?
Thank you! | All you need to do is create a custom page for your theme. Here is a very brief example:
Create a file called: page-example.php
```
<?php
/*
Template Name: Example Page
*/
?>
<?php get_header(); ?>
The html code will go here. Don't add the <head> or <body> info.
<?php get_footer(); ?>
```
The next thing to do is add the following to your functions.php file:
```
function load_example_scripts() {
wp_enqueue_script('moment', get_stylesheet_directory_uri() . '/js/example.js');
}
add_action( 'wp_enqueue_scripts', 'load_example_scripts' );
```
Now upload the page-example.php to your main template folder (where header.php, footer.php, functions.php are)
I usually add a folder to my themes named "JS" and put all jquery scripts there. So upload the example.js file to the "JS" folder of your theme.
Finally, go to the wordpress admin, and edit the page where you want this to appear and on the side menu under "templates", select "example".
I would have to see the exact code to give you more help, but that is the basic idea. |

```
Image showing for custom field.
```
add_filter('the_content', 'custom_fields_for_feeds');
add_filter('the_meta','custom_files_for_feed');
function custom_fields_for_feeds( $content ) {
global $post;
global $post;
// Get the custom fields ***
// Checks for thumbnail

// Checks for thumbnail alt text
$image_alt = get_post_meta($post->ID, 'Thumbnail Alt', $single = true);
if($image_alt == '') { $image_alt = 'This image has no alt text'; }
if($image !== '') {
$content = '<figure><img src="'.$image.'" alt="'.$image_alt.'" /></figure>' . $content;
return $content;
}
else {
$content = $content;
return $content;
}
add_filter('the_content', 'custom_fields_for_feeds');
add_filter('the_meta','custom_files_for_feed');
```
You can also use custom image fields to display in the RSS feed.

| As everyone might be aware that there are many wordpress website builders in the market, Can anyone explain me whats the real difference between Theme Builders and Page Builders? I looked up in google but couldn't find the answer to it. | Here is the [link](http://wpcodesnippet.com/display-featured-post-thumbnails-wordpress-feeds/) I found a solution. How to display featured post thumbnails in WordPress feeds
paste this code snippet in your theme functions.php file
```
// display featured post thumbnails in WordPress feeds
function wcs_post_thumbnails_in_feeds( $content ) {
global $post;
if( has_post_thumbnail( $post->ID ) ) {
//if you want to show thumbnail image
$content = '<figure>' . get_the_post_thumbnail( $post->ID, 'thumbnail' ) . '</figure>' . $content;
// if you want to show full image
//$content = '<p>' . get_the_post_thumbnail( $post->ID,'full' ) . '</p>' . $content;
//if you want to custom image using add_image_size()
//$content = '<figure>' . get_the_post_thumbnail( $post->ID, 'custom-image-size' ) . '</figure>' . $content;
}
return $content;
}
add_filter( 'the_excerpt_rss', 'wcs_post_thumbnails_in_feeds' );
add_filter( 'the_content_feed', 'wcs_post_thumbnails_in_feeds' );
```
This is the concepts how to you show external link image. How you fetch the external image, it upon you.
it's showing all the post same image. Just change image link for each post.
ex: src="'.$image\_url.'"
```
function rss_feed_from_external_link( $content ) {
global $post;
$content = '<figure><img width="150" height="128" src="https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png" class="attachment-thumbnail size-thumbnail wp-post-image" alt="" sizes="100vw" /></figure>' . $content;
return $content;
}
add_filter( 'the_excerpt_rss', 'rss_feed_from_external_link' );
add_filter( 'the_content_feed', 'rss_feed_from_external_link' );
```
Image showing for custom field.
```
add_filter('the_content', 'custom_fields_for_feeds');
add_filter('the_meta','custom_files_for_feed');
function custom_fields_for_feeds( $content ) {
global $post;
global $post;
// Get the custom fields ***
// Checks for thumbnail
$image = get_post_meta($post->ID, 'Thumbnail', $single = true);
// Checks for thumbnail alt text
$image_alt = get_post_meta($post->ID, 'Thumbnail Alt', $single = true);
if($image_alt == '') { $image_alt = 'This image has no alt text'; }
if($image !== '') {
$content = '<figure><img src="'.$image.'" alt="'.$image_alt.'" /></figure>' . $content;
return $content;
}
else {
$content = $content;
return $content;
}
add_filter('the_content', 'custom_fields_for_feeds');
add_filter('the_meta','custom_files_for_feed');
```
You can also use custom image fields to display in the RSS feed.

| I decided to integrate several standalone WordPress websites into a single Multisite installation.
I created a brand new Multisite install with subdomains, created a MU network site with subdomain URL, and exported the content from the original standalone site, then imported that content into the subdomain MU site. I then deleted the original standalone site from cPanel, and set the MU site's domain name to the original domain name.
The main site loads fine now on its original domain name, but when I try to login to the subdomain site at `site.example.com/wp-admin/` (using the brand new multisite's network admin user credentials), I receive an error:
>
> ERROR: Cookies are blocked or not supported by your browser. You must

But cookies *are* enabled in Chrome.
I tried adding the following to `wp-config.php`:
```
define('COOKIE_DOMAIN', false);
```
...but the issue remains.
The same issue occurs if I use WP Migrate DB Pro to pull in a standalone website into a MU subdomain site, then delete the standalone site from cPanel, and then set the MU subdomain site's domain to be the original standalone site's domain name... the site's frontend loads fine, but I just can't login to WP admin. | First clear your browser's cache (including cookies), and your server's cache (e.g. cache plugins). Then set the following in your `wp-config.php` file:
```
define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');
```
Also, you may checkout the [answer from HERE](https://community.bitnami.com/t/wp-multisite-multidomains-cookies-issue/46603):
```
define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'example.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
define('SUNRISE', 'on');

259,936 | <p>Having practised mirroring an existing wordpress site, I'm ready to migrate my website to a new server. Having simplified the steps necessary to do this, I'm hoping the following will work without having to change any database entries or Wordpress files. The domain name will stay the same, only the host will change.</p>
<p>1) Backup wordpress files from oldsite<br>
2) Back up database from oldsite<br>
3) Create a database on the new site using the same database name and password from the oldsite. (That way there is no need to change the original config file).<br>
4) Upload oldsite database into newsite database.<br>
5) Upload all wordpress files onto new server<br>
6) Have the DNS record of my domain changed to point to the new server and directory.<br>
7) Wait up to 48 hours (Although the TTL value is set to 10 minutes)<br>
8) Newsite should be working identically to the oldsite<br>
9) Delete all files from oldsite </p>
<p>Should this work okay? </p>
<p>My website is live and my main source of income. It also has good Google rankings which I have spent years achieving. My biggest fear is that by moving from one server to another Google will see it as a duplicate or brand new site and penalize me in the search results. I've also been told that all the Facebook likes on articles will break and will reset to zero. Is that correct?</p>

| Having practised mirroring an existing wordpress site, I'm ready to migrate my website to a new server. Having simplified the steps necessary to do this, I'm hoping the following will work without having to change any database entries or Wordpress files. The domain name will stay the same, only the host will change.
1) Backup wordpress files from oldsite
2) Back up database from oldsite
3) Create a database on the new site using the same database name and password from the oldsite. (That way there is no need to change the original config file).
4) Upload oldsite database into newsite database.
5) Upload all wordpress files onto new server
6) Have the DNS record of my domain changed to point to the new server and directory.
7) Wait up to 48 hours (Although the TTL value is set to 10 minutes)
8) Newsite should be working identically to the oldsite
9) Delete all files from oldsite
Should this work okay?
My website is live and my main source of income. It also has good Google rankings which I have spent years achieving. My biggest fear is that by moving from one server to another Google will see it as a duplicate or brand new site and penalize me in the search results. I've also been told that all the Facebook likes on articles will break and will reset to zero. Is that correct? | In `functions.php` child theme include `template-tags.php` from parent theme:
```
require_once get_theme_file_path( '../parent-theme/inc/template-tags.php' );
```
In the child theme `template-tags.php` remove parent action and add the child action replacing it:
```
remove_action( 'tag', 'parent-function', 0 );
add_action( 'tag', 'new-child-function', 10 );

| I wanted to exclude `pages` from the search results, and found many ways to do it, and was wondering why use `!is_admin()` or `is_main_query()` and which way would be better.
```
add_filter('pre_get_posts','search_filter');
function search_filter($query) {
if ($query->is_search) {
$query->set('post_type', 'post');
}
return $query;
}
```
---
```
add_filter('pre_get_posts','search_filter');
function search_filter($query) {
if ( !is_admin() && $query->is_search) {
$query->set('post_type', 'post');
}
return $query;
}
```
---
```
add_action('pre_get_posts','search_filter');
function search_filter($query) {
if ( !is_admin() && $query->is_main_query() ) {
if ($query->is_search) {
$query->set('post_type', 'post');
}
}
}
``` | Note that when we use:
```
$query->set( 'post_type', 'post' );
```
then we're overriding all searchable post types, not only the `page` post type.
That may be just fine in some cases, and we're done using some of your `pre_get_posts` snippets that fit our needs.
But sometimes we don't want to hard fix it that way. Here we discuss that kind of scenarios.
**Using the register\_post\_type\_args filter.**
When the post type isn't specified, the `WP_Query` search uses any post types that are searchable, [namely](https://github.com/WordPress/WordPress/blob/d92e1fb1e4ebc3d9c28821023a797f725f7af348/wp-includes/class-wp-query.php#L2264):
```
$in_search_post_types = get_post_types( array('exclude_from_search' => false) );
```
When we register a post type, we can set the `exclude_from_search` parameter as false to exclude it from search.
We can modify it for the `page` post type setup with:
```
add_filter( 'register_post_type_args', function( $args, $name )
{
// Target 'page' post type
if( 'page' === $name )
$args['exclude_from_search'] = true;
return $args;
}, 10, 2 );
```
More about `register_post_type()` [here](https://developer.wordpress.org/reference/functions/register_post_type/).
**Examples**
Here are examples where the page post type would be excluded from the search, using the above filtering:
* Main query search on the front-end with
```
https://example.tld?s=testing
```
* Secondary query like:
```
$query = new WP_Query( [ 's' => 'testing' ] );
```
* Secondary query like:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => 'any' ] );
```
**Some notes on queries with pre set post types:**
Let's consider cases where the post types are fixed, like:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => [ 'page', 'post'] ] );
```
If the post type is set by some array `$post_type`, then we can filter the `'page'` out it with
```
if( is_array( $post_type ) && count( $post_type ) > 1 )
{
$post_type = array_filter(
$post_type,
function( $item ) { return 'page' !== $item; }
);
}
```
If we don't have direct access to that array, we could use e.g. `pre_get_posts` to remove the 'page' from the post type array, with help of the `get`/`set` methods of `WP_Query`. Here's an example for the main search query on the front end:
```
add_action( 'pre_get_posts', function search_filter( \WP_Query $query )
{
if( ! $query->is_search() || ! $query->is_main_query() || ! is_admin() )
return;
$post_type = $query->get( 'post_type' );
if( is_array( $post_type ) && count( $post_type ) > 1 )
{
$post_type = array_filter(
$post_type,
function( $item ) { return 'page' !== $item; }
);
$query->set('post_type', $post_type );
}
} );
```
Why did we check the array count > 1 here?
That's because we should be careful to removing `'page'` from examples like:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => [ 'page' ] ] );
$query = new WP_Query( [ 's' => 'testing', 'post_type' => 'page' ] );
```
as an empty array or an empty string, for the post type:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => [] ] );
$query = new WP_Query( [ 's' => 'testing', 'post_type' => '' ] );
```
will fall back to the `'post'` post type.
Note that:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => 'page, post' ] );
```
isn't supported, as the resulting post type would be `'pagepost'`.
In these cases, where we don't have direct access to the `WP_Query` objects, we could halt the query with tricks like `'post__in' => []` or `1=0` in the search WHERE query part or even play with the `posts_pre_query` filter or using some more advanced methods. There are plenty of answers on this site about that. [This](https://wordpress.stackexchange.com/q/229722/26350) and [this](https://wordpress.stackexchange.com/q/226065/) is what I recall at the moment.
The `null` case:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => null ] );
```
falls back to `'any'` post types:
Hope it helps!
**PS:**
Also note the inconsistency in your snippets, as you have both
```
add_filter('pre_get_posts','search_filter');
```
and
```
add_action('pre_get_posts','search_filter');
```
It's considered an *action*, but it will not make any difference, as actions are wrapped as filters, behind the scenes. |

**Using the register\_post\_type\_args filter.**
When the post type isn't specified, the `WP_Query` search uses any post types that are searchable, [namely](https://github.com/WordPress/WordPress/blob/d92e1fb1e4ebc3d9c28821023a797f725f7af348/wp-includes/class-wp-query.php#L2264):
```
$in_search_post_types = get_post_types( array('exclude_from_search' => false) );
```
When we register a post type, we can set the `exclude_from_search` parameter as false to exclude it from search.
We can modify it for the `page` post type setup with:
```
add_filter( 'register_post_type_args', function( $args, $name )
{
// Target 'page' post type
if( 'page' === $name )
$args['exclude_from_search'] = true;
return $args;
}, 10, 2 );
```
More about `register_post_type()` [here](https://developer.wordpress.org/reference/functions/register_post_type/).
**Examples**
Here are examples where the page post type would be excluded from the search, using the above filtering:
* Main query search on the front-end with
```
https://example.tld?s=testing
```
* Secondary query like:
```
$query = new WP_Query( [ 's' => 'testing' ] );
```
* Secondary query like:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => 'any' ] );
```
**Some notes on queries with pre set post types:**
Let's consider cases where the post types are fixed, like:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => [ 'page', 'post'] ] );
```
If the post type is set by some array `$post_type`, then we can filter the `'page'` out it with
```
if( is_array( $post_type ) && count( $post_type ) > 1 )
{
$post_type = array_filter(
$post_type,
function( $item ) { return 'page' !== $item; }
);
}
```
If we don't have direct access to that array, we could use e.g. `pre_get_posts` to remove the 'page' from the post type array, with help of the `get`/`set` methods of `WP_Query`. Here's an example for the main search query on the front end:
```
add_action( 'pre_get_posts', function search_filter( \WP_Query $query )
{
if( ! $query->is_search() || ! $query->is_main_query() || ! is_admin() )
return;
$post_type = $query->get( 'post_type' );
if( is_array( $post_type ) && count( $post_type ) > 1 )
{
$post_type = array_filter(
$post_type,
function( $item ) { return 'page' !== $item; }
);
$query->set('post_type', $post_type );
}
} );
```
Why did we check the array count > 1 here?
That's because we should be careful to removing `'page'` from examples like:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => [ 'page' ] ] );
$query = new WP_Query( [ 's' => 'testing', 'post_type' => 'page' ] );
```
as an empty array or an empty string, for the post type:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => [] ] );
$query = new WP_Query( [ 's' => 'testing', 'post_type' => '' ] );
```
will fall back to the `'post'` post type.
Note that:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => 'page, post' ] );
```
isn't supported, as the resulting post type would be `'pagepost'`.
In these cases, where we don't have direct access to the `WP_Query` objects, we could halt the query with tricks like `'post__in' => []` or `1=0` in the search WHERE query part or even play with the `posts_pre_query` filter or using some more advanced methods. There are plenty of answers on this site about that. [This](https://wordpress.stackexchange.com/q/229722/26350) and [this](https://wordpress.stackexchange.com/q/226065/) is what I recall at the moment.
The `null` case:
```
$query = new WP_Query( [ 's' => 'testing', 'post_type' => null ] );
```
falls back to `'any'` post types:
Hope it helps!
**PS:**
Also note the inconsistency in your snippets, as you have both
```
add_filter('pre_get_posts','search_filter');
```
and
```
add_action('pre_get_posts','search_filter');
```
It's considered an *action*, but it will not make any difference, as actions are wrapped as filters, behind the scenes. |

**1.** However I would like to *only* apply it to our woocommerce product pages and categories so it doesnt work on home/blog pages. How would i do that?
I can do this *poorly* by editing WooCommerce core files but i know that's a horrible idea so I'm seeking out help on how to do it correctly via my functions.php file.
**2.** Also i would like to know how to apply it to all pages except the home page should that be a better option later on.
Many thanks! | There are two ways you could do that.
1. Using JS only
================
WordPress themes normally use the [`body_class()`](https://developer.wordpress.org/reference/functions/body_class/) function. As a result you'll see that the `<body>` tag will have lots of classes. You can then target pages with a specific class to run your code in JavaScript:
```
if( $('body.whateverclass').length || $('body.anotherclass').length ){
// Your JS code here
}
```
2. Using PHP
============
You can harness [`wp_localize_script()`](https://codex.wordpress.org/Function_Reference/wp_localize_script) to send a flag to your code.
Let's suppose you enqueued a file called `site.js` with a handle name of `site`, in your `functions.php` you'll have:
```
wp_register_script( 'site', 'path/to/site.js' );
wp_enqueue_script( 'site' );
```
You can now add some flags:
```
wp_register_script( 'site', 'path/to/site.js' ); # Unchanged
$value = '';
if ( is_shop() || is_some_other_condition() ){
$value = 'yes';
}
wp_localize_script( 'site', 'MYSITE', $value );
wp_enqueue_script( 'site' ); # Unchanged
```
You can then check the `MYSITE` variable in JavaScript:
```
if( 'yes' === MYSITE ){
// Your JS code here
}
```
Edit:
[You asked](https://wordpress.stackexchange.com/questions/259987/apply-jquery-script-to-only-woocommerce-product-pages-and-categories/259996#comment385846_259996) how to put it in the footer.php:
```
<script>
jQuery(document).ready(function($){
if( $('body.product-template-default').length || $('body.anotherclass').length ){
if ( $(window).width() < 768 || window.Touch) {
$('html, body').animate({ scrollTop: $("#primary").offset().top}, 2000);
}
}
});
</script>

Any and all help is appreciated. | To keep your options open with an open architecture you can create a multisite Network installation with multiple Networks. This means for each separate client you would give them a new Network. The advantage of this is that you can offer the scalability to Clients and keep your options open. Clients can easily have more sites (sub-domains) added to their Network.
structure would be
```
Network1 > abc.com (main site for the whole Wordpress Multi-Network install)
Network2 > client1.com
Network3 > client2.com
Network4 > client3.com

```
this shows,

* Client3 has a main site "client3.com" and also one "client3.com/shop" subsite/sub-domain.
To make all this happen you need to install the plugin [wp-multi-network](https://wordpress.org/plugins/wp-multi-network/). Follow the install guidance for setup within wp-config.php for the plugin and
also add this to your wp-config.php file..
```
define( 'WP_HOME', '//' . $_SERVER['HTTP_HOST'] );
define( 'WP_SITEURL', '//' . $_SERVER['HTTP_HOST'] );
```

| How can I use `do_action` and `add_action` to return an array in `do_action`?
My sample code:
```
function name_fun_one(){
$namearray[] = array('k1'=> 'text1', 'k2' => 'text1');
$namearray[] = array('k1'=> 'text2', 'k2' => 'text2');
do_action('add_in_namearray');
foreach($namearray as $val)
{
//loop
}
}
function add_name_fun_one()
{
$namearray[] = array('k1'=> 'text3', 'k2' => 'text3');
$namearray[] = array('k1'=> 'text4', 'k2' => 'text4');
}
add_action('name_fun_one', 'add_name_fun_one');
``` | The pagination functions work off of the main query, so you'd need to use `pre_get_posts` instead of creating a new query for them to work.
But, you're using `WP_User_Query`, so the standard pagination system will never work for you. You're going to have to 'roll your own' pagination system here, and generate your own URLs manually, and set the page yourself based on the URL |

I don't know if using the toolbar would be a suitable workaround for you, but if so, then you could do something like:
```
add_action ('wp_before_admin_bar_render', 'wpse_admin_toolbar_test') ;
function
admin_toolbar ()
{
global $wp_admin_bar ;
$args = array (
'id' => 'wpse_admin_toolbar_test',

$node = $wp_admin_bar->add_node ($args) ;
for ($i = 0 ; $i < 4 ; $i++) {
$args = array (
'id' => "wpse_admin_toolbar_test_item_{$i}",
'parent' => 'wpse_admin_toolbar_test',
'title' => "Item $i",
) ;
$wp_admin_bar->add_node ($args) ;
for ($y = 0 ; $y < 3 ; $y++) {
$args = array (
'id' => "wpse_admin_toolbar_test_item_{$i}_subitem_{$y}",

'parent' => "wpse_admin_toolbar_test_item_{$i}_subitem_{$y}",
'title' => "Sub-Sub Item $z",
// in the real-world, this URL would be to something that
// would perform the action for this node
'href' => admin_url (),
) ;
$wp_admin_bar->add_node ($args) ;
}
}
}
return ;
}
```

However, we do need them to be on the same domain...

Can someone explain what i am doing wrong here ? | Are you sure you theme is active?
If you see your style.css code it should not have only the CSS code but also the Theme defination at header of your style.css.
Please make sure if your theme is active.
The above code for loading CSS file looks good and should work if your theme is active.
**Update** :
Have you added `wp_head()` and `wp_footer()` in `header.php` and `footer.php` respectively?
`wp_head()` should be added before `</head>` tag in your HTML and `wp_footer()` should be added before `</body>` tag in HTML. |

| I am getting post id from url like this
```
https://www.example.com/download/?id=241
```
and in base of this id i want to get post data from db but it is getting nothing i tried this code
```
<?php
$id = $_GET['id'];
// WP_Query arguments
$args = array (
'category_name' => 'download',
'showposts' => '1',
'post_id' => $id,
'post_type' => 'page'
);
// The Query
$my_query = new WP_Query( $args );
//print_r($my_query);
if ($my_query->have_posts() ) : while ($my_query->have_posts() ) : $my_query->the_post(); // Start the loop
$thumb_id = get_post_thumbnail_id();
$thumb_url = wp_get_attachment_image_src($thumb_id, true);
?>
<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>" target="_blank">
<img src="<?php echo $thumb_url[0]; ?>" />
<h3><?php the_title(); ?></h3>
<time>تاريخ النشر: <?php the_time('l, F j, Y'); ?></time>
</a>
<?php
endwhile; endif;// End the Loop and Check for Posts
wp_reset_query(); // Reset the loop
?>
```
So i want to get the data by using the `id` i am getting through url. So please tell me what can i do with my code | You may use $\_GET parameter to get the id.
```
$id = $_GET['id'];
```
Or try this:
```
global $post;
echo $post->ID;
```
But it seems you have a problem in the args array. when you know the exact id of requested post you don't need to use it like that. you can use this instead:
```
get_post($id);
```
And then you do not need to loop through because you have one post to show. |

The answer could actually be somewhat complex, but mainly having it inside an action callback only registers them when needed, just putting it inside the `functions.php` it happens always when the theme is active.
First of all this can be a waste of performance, registering stuff that is never used. You might think that it should be there in any case, but actually in WP there are plenty of situations where frontend JS/CSS is totally irrelevant. The most obvious situation is the backend. But also some plugin might create an endpoint that doesn't need JS/CSS. And there are plenty more of that.
Last but not least by having this on an action third party code (plugins, child themes) can unhook the callback to e.g. replace it with something else.
I hope this gives you a basic understanding why it is good practice to only do stuff on the appropriate hook.

Thanks | I'm guessing this is a custom "plugin" where you are wanting to run a file externally that connects to the WordPress database, not really as a standard plugin which loads within WordPress environment, as in that case as @belinus says you can just use `$wpdb` class.
Anyway, since `ABSPATH` is defined IN `wp-config.php`, you can't use `ABSPATH` to find and load `wp-config.php` - because it hasn't loaded and thus isn't defined yet. That's the flawed logic... hence the errors you are getting.
If you know for certain that `wp-config.php` is in a directory above where the "plugin" file is, you can do something like this:
```
function find_require($file,$folder=null) {
if ($folder === null) {$folder = dirname(__FILE__);}
$path = $folder.'/'.$file;
if (file_exists($path)) {require($path); return $folder;}
else {
$upfolder = find_require($file,dirname($folder));
if ($upfolder != '') {return $upfolder;}
}
}
$configpath = find_require('wp-config.php');
```
This will recursively search for `wp-config.php` above the plugin file directory and load it when it does. (Again this assumes the `wp-config.php` is located in a directory above the plugin file.) |

| So I have this theme where there is an about section that is showing in the customizer, but there isn't a specific post type on the admin page that adds post to this section.
How do I add post to the about section with the template code stated below.
```
if(isset($xt_corporate_lite_opt['xt_about_page']) &&
$xt_corporate_lite_opt['xt_about_page'] != '') {
$xt_query = new WP_Query(array(
'page_id' => $xt_corporate_lite_opt['xt_about_page']
));
if ($xt_query->have_posts()) {
while ($xt_query->have_posts()) {
$xt_query->the_post();
the_content();
}
}
wp_reset_postdata();
}
``` | You can try this code to show only post.
```
if(isset($xt_corporate_lite_opt['xt_about_page']) && $xt_corporate_lite_opt['xt_about_page'] != '') {
$args = array( 'post_type' => 'post');
$xt_query = new WP_Query($args);
if ($xt_query->have_posts()) {
while ($xt_query->have_posts()) {
$xt_query->the_post();
the_content();
}
}
wp_reset_postdata();

I am integrating a custom plugin in that I have added few functions with help of hooks, So I need to debug something in it. In this I need if I can enter any text or data into WordPress logs.
If so Please let me know the procedure for generating log into WordPress. | You can enable WordPress logging adding this to `wp-config.php`:
```
// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
```
you can write to the log file using the [`error_log()` function](https://www.php.net/manual/en/function.error-log.php) provided by PHP.
The following code snippet is a very useful function wrapper for it, make it available in your plugin:
```
if (!function_exists('write_log')) {
function write_log($log) {
if (true === WP_DEBUG) {
if (is_array($log) || is_object($log)) {
error_log(print_r($log, true));

error_log($log);
}
}
}
}
write_log('THIS IS THE START OF MY CUSTOM DEBUG');
//i can log data like objects
write_log($whatever_you_want_to_log);

if you cant find the `debug.log` file, try generating something for it, since it will not be created if there are no `errors`, also in some hosted servers you might need to check where the error log is located using php info. |

Full WP Codex documentation here:
<https://codex.wordpress.org/Function_Reference/register_post_type>
This is an extremely simplified example to show the basics: create a function to handle registration, hook that function to WP's `init` action.
In a real application you will want to define your labels and other arguments for the `register_post_type()` function.
Depending on how you intend to use the testimonials on the front end, you will need templates for your new custom post type:
`archive-testimonial.php` <-- this will display all of the published testimonials; your example page
`single-testimonial.php` <-- used to display a single testimonial; when a user clicks through to see all of the details on a single testimonial
This will get you started. For advanced features, like displaying random testimonials on a page, you'll want to read up on using the `WP_Query` class for custom queries.

| I am trying to clean up a DB of 4000+ posts and the editors TAGGED the posts that they want to keep with an "audit2017" tag. Is there a way with SQL to select all posts \*without this tag and delete them?
I am not very experienced with SQL but can manage this if I had the right query.
Any help appreciated, thanks! | I just created a function that can bulk delete posts that doesn't have specific tag(s).
You need to have the IDs of the tags that you want to keep their posts.
[In case you don't know how to get those IDs: Quick solution is go to tags page on the website admin panel. Click on the tag. In the new page address bar you can see the tag\_id]
Replace the "TagID"s with your actual tag IDs on this line:
```
$tags_to_delete = array( $TagID1, $TagID2 , ... );
```
Then place the code at the end of your theme's functions.php file. Open your homepage. It will move all the posts that don't have specific tag(s) to trash.
This code will be run every time that you open a page in your frontend.
The runtime depends on you number of post and your server configuration.
I tested it for about 3500 posts on a not very high config server and it took about 40 seconds to finish.
I strongly suggest to remove the code from your website after you are done with it.
```
// Change the $TagIDs with the tag IDs in your database
$tags_to_delete = array( $TagID1, $TagID2 , ... );
// This function will bulk delete posts that don't have specific tag(s)
function delete_posts_by_not_tag( $tags ) {
// WP_Query arguments
$args = array(
'post_type' => array( 'post' ),
'nopaging' => true,
'posts_per_page' => '-1',
'tag__not_in' => array( $tags ),
);
// The Query
$query = new WP_Query( $args );
// The Loop
if ( $query->have_posts() ) {
$totalpost = $query->found_posts;
echo "Number of Posts: " . $totalpost;
echo "<hr>";
while ( $query->have_posts() ) {
$query->the_post();
$current_id = $post->ID;
wp_delete_post( $current_id );
echo "Post by ID '" . $current_id . "' is deleted.<br>";
}
echo "<hr>";
} else {
echo "No post found to delete!";
}
// Restore original Post Data
wp_reset_postdata();
}
// Run the function to delete all the posts that don't have specific tag(s)
delete_posts_by_not_tag( $tags_to_delete );

260,410 | <p>I am creating a custom admin section. I have the following code:</p>
<pre><code>// Top level menu
add_menu_page('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// Adding this function to make the first submenu have a different name than the main menu
// Details: https://wordpress.stackexchange.com/questions/66498/add-menu-page-with-different-name-for-first-submenu-item
add_submenu_page('Books', 'Books', 'All Books', 'publish_posts', 'books', 'render_books_page');
// The Add Book menu page
add_submenu_page('Books', 'Add New Book', 'Add Book', 'publish_posts', 'add-book', 'render_add_book_page');
// The Edit Book menu page (this page is hidden from the menu, and accessed via the All Books page only)
add_submenu_page(null, 'Edit Book', 'Edit Book', 'publish_posts', 'edit-book', 'render_edit_book_page');
</code></pre>
<p>As you notice in the last line of code, the first parameter of the <code>add_submenu_page()</code> is set to <code>null</code>. This is to ensure that the <strong>Edit Book</strong> page is hidden (<a href="https://wordpress.stackexchange.com/questions/73622/add-an-admin-page-but-dont-show-it-on-the-admin-menu">more details about this here</a>). Access to the <strong>Edit Book</strong> page is done via the main menu, from the list of all books.</p>
<p>The problem is, when I go to the <strong>Edit Book</strong> page, the Admin Menu to the left collapses (on the other hand, the default WordPress behaviour is as follows: If you go to an <strong>Edit Post</strong> page, or the <strong>Edit Page</strong> page, both the <strong>Posts</strong> and <strong>Pages</strong> menu stay expanded for their respective <em>edit</em> pages). In my case, the menu collapses.</p>
<p>How can I keep the menu to the left expanded when I go to the <strong>Edit Book</strong> page, to behave in a similar fashion to that of WordPress?</p>
<p>Thanks.</p>

As you notice in the last line of code, the first parameter of the `add_submenu_page()` is set to `null`.

add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);

}
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );

And we must hide the first menu item
```
add_action( 'admin_enqueue_scripts', function () {
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// Load CSS file
wp_enqueue_style('book-edit', 'path/to/css/menu.css');
// Load jQuery
wp_enqueue_script('jquery');
// Load
wp_enqueue_script('book-edit-script', 'path/to/js/menu.js');

```
#toplevel_page_books li.current {
display: none;
}
#toplevel_page_books li.wp-first-item {
display: list-item;
}
```
Also the content of 'menu.js' is:
```
jQuery(document).ready(function($) {
$('#toplevel_page_books li.wp-first-item').addClass('current');
});
```
---
**TL;DR**
To understand how all this works, here is a step-by-step explanation.
**Step 1:** We add the main menu item (the *books* menu item) to display the list of books
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
}
```
**Step 2:** We add the *add-book* menu item as a submenu to the main *books* menu item
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
**Step 3:** Finishing Step 2 above adds the books menu item, The menu list on the left side would look like this:
```
Books <---------- This is the main top level menu names
Books <---------- This is the first sub-menu
Add New <---------- This is the second sub-menu
```
However, we should fix this. The intended list should look like this
```
Books <---------- This is the main top level menu names
All Books <---------- This is the first sub-menu
Add New <---------- This is the second sub-menu
```
To do this, we have to modify our code as follows:
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// Adding this function to make the first submenu have a different name than the main menu
add_submenu_page('books', 'Books', 'All Books', 'publish_posts', 'books', 'render_books_page' );
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
**Step 4:** Next we should add a sub menu to edit books (the *edit-book* menu item). After adding his submenu, and when we are at the *edit-book* page, the menu on the left should look like this:
```
Books
All Books <---------- When we are in the 'edit-book' page, this menu item is selected and is highlighted (typically white in color), and also clicking on "All Books" would return us back to the "All Books" page.
Add New
```
The solution I tried first was what I posted in my original question, which did not work exactly. So, based on discussions with @Ian and looking at his proposed solution, I came up with this:
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// Adding this function to make the first submenu have a different name than the main menu
add_submenu_page('books', 'Books', 'All Books', 'publish_posts', 'books', 'render_books_page' );
// If we are in the 'edit-book' page, then display the 'edit-book' submenu, otherwise, display the regular 'books' menu
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// Display the 'edit-book' menu page and display it as the 'all-books' page
// Notice that the slug is 'edit-book', but the display name is 'All Books'
add_submenu_page('books', 'Edit Book', 'All Books', 'publish_posts', 'edit-book', 'render_edit_book_page' );
}
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
Now, if we click on the 'books' menu item, or the 'add-book' menu item, then everything is fine. However, if we try to edit an existing book then the following menu list will be displayed
```
Books
All Books <---------- This is the first sub-menu (due to the first submenu call)
All Books <---------- This is the 'edit-book' page (HIGHLIGHTED)
Add New
```
**Step 5:** Now we notice the following: By clicking on the first submenu, the "All Books" page will be rendered, and clicking on the second submenu will render the "Edit" page; and in our case, we want to render the "All Books" page.
Therefore, we have to hide the SECOND submenu and make the first submenu highlighted. This is done as follows:
```
add_action( 'admin_enqueue_scripts', function () {
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// Load CSS file
wp_enqueue_style('book-edit', 'path/to/css/menu.css');
// Load jQuery
wp_enqueue_script('jquery');
// Load
wp_enqueue_script('book-edit-script', 'path/to/js/menu.js');
}
});
```
And the content of `menu.css` is:
```
#toplevel_page_books li.current {
display: none;
}
#toplevel_page_books li.wp-first-item {
display: list-item;
}
```
Also the content of 'menu.js' is:
```
jQuery(document).ready(function($) {
$('#toplevel_page_books li.wp-first-item').addClass('current');
});
```
And now everything works like a charm. |
260,416 | <p>I'm trying to find a way to get my posts with different look depending on their category.</p>
<p>I have first tried to do it using the <a href="https://developer.wordpress.org/files/2014/10/template-hierarchy.png" rel="nofollow noreferrer">template hierarchy</a> but it seems there is no pattern for the category posts. (ie single-cat-mycategory.php)</p>
<p>So then within single.php I tried the conditional tagging using <code>is_category()</code> but my understanding it's only working for the <code>archive</code> pages.</p>
<p>Finally, I'm now trying to use the <code>is_single()</code> conditional tagging where first I'm looking for all the posts corresponding to my category and pass it as a parameter of <code>is_single()</code></p>
<p><strong>In functions.php</strong></p>
<pre><code>function get_post_id_by_cat(){
$args = [
'post_type' => 'post',
'post_status' => 'publish',
'category_name' => 'my_category',
];
$cat_query = new WP_Query( $args );
if ($cat_query -> have_posts()){
while ($cat_query -> have_posts()){
$cat_query -> the_post();
$post_ids[] = get_the_ID();
}
wp_reset_postdata();
}
</code></pre>
<p><strong>In single.php</strong></p>
<pre><code>$my_cat_posts = get_post_id_by_cat();
if (is_single($my_cat_posts)) {
while ( have_posts() ) : the_post();
//do my stuff here
endwhile;
}
</code></pre>
<p><strong>My first question</strong> is this in term of Wordpress design a good way to do this or is there a better way as my concern is mainly for performance, with this method.</p>
<p><strong>If it's ok,</strong>
My issue is that <code>$post_ids</code> is storing the data in a php object format and not an array so <code>is_single()</code> doesn't get the posts ids properly as parameter.
And i don't get how I can get it converted to an array.</p>
<p><code>$post_ids[] = to_array(get_the_ID());</code> return</p>
<blockquote>
<p>Uncaught Error: Call to undefined function to_array()</p>
</blockquote>
<p>or
<code>$post_ids[] = (array)get_the_ID();</code> return each post ids stil has object but within a array like this:</p>
<pre><code>array(8) {
[0]=>
array(1) {
[0]=>
int(5415)
}…
</code></pre>
<p>or
<code>$post_ids[] = get_object_vars(get_the_ID());</code> return </p>
<blockquote>
<p>get_object_vars() expects parameter 1 to be object, integer given</p>
</blockquote>
<p>But if pass this array it does work properly:</p>
<pre><code>$array = ['5415','5413','5411','5401'];
</code></pre>
<p>Hope this is clear enough,</p>
<p>Thanks for any input!</p>
<p>Matth.</p>

| I'm trying to find a way to get my posts with different look depending on their category.
I have first tried to do it using the [template hierarchy](https://developer.wordpress.org/files/2014/10/template-hierarchy.png) but it seems there is no pattern for the category posts. (ie single-cat-mycategory.php)
So then within single.php I tried the conditional tagging using `is_category()` but my understanding it's only working for the `archive` pages.
Finally, I'm now trying to use the `is_single()` conditional tagging where first I'm looking for all the posts corresponding to my category and pass it as a parameter of `is_single()`
**In functions.php**
```
function get_post_id_by_cat(){
$args = [
'post_type' => 'post',
'post_status' => 'publish',
'category_name' => 'my_category',
];
$cat_query = new WP_Query( $args );
if ($cat_query -> have_posts()){
while ($cat_query -> have_posts()){
$cat_query -> the_post();
$post_ids[] = get_the_ID();
}
wp_reset_postdata();
}
```
**In single.php**
```
$my_cat_posts = get_post_id_by_cat();
if (is_single($my_cat_posts)) {
while ( have_posts() ) : the_post();
//do my stuff here
endwhile;
}
```
**My first question** is this in term of Wordpress design a good way to do this or is there a better way as my concern is mainly for performance, with this method.
**If it's ok,**
My issue is that `$post_ids` is storing the data in a php object format and not an array so `is_single()` doesn't get the posts ids properly as parameter.
And i don't get how I can get it converted to an array.
`$post_ids[] = to_array(get_the_ID());` return
>
> Uncaught Error: Call to undefined function to\_array()
>
>
>
or
`$post_ids[] = (array)get_the_ID();` return each post ids stil has object but within a array like this:
```
array(8) {
[0]=>
array(1) {
[0]=>
int(5415)
}…
```
or
`$post_ids[] = get_object_vars(get_the_ID());` return
>
> get\_object\_vars() expects parameter 1 to be object, integer given
>
>
>
But if pass this array it does work properly:
```
$array = ['5415','5413','5411','5401'];
```
Hope this is clear enough,
Thanks for any input!

add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// Adding this function to make the first submenu have a different name than the main menu
add_submenu_page('books', 'Books', 'All Books', 'publish_posts', 'books', 'render_books_page' );
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// The Edit Book menu page and display it as the All Books page
add_submenu_page('books', 'Edit Book', 'All Books', 'publish_posts', 'edit-book', 'render_edit_book_page' );
}
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
And we must hide the first menu item
```
add_action( 'admin_enqueue_scripts', function () {
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// Load CSS file
wp_enqueue_style('book-edit', 'path/to/css/menu.css');
// Load jQuery
wp_enqueue_script('jquery');
// Load
wp_enqueue_script('book-edit-script', 'path/to/js/menu.js');
}
});
```
And the content of `menu.css` is:
```
#toplevel_page_books li.current {
display: none;
}
#toplevel_page_books li.wp-first-item {
display: list-item;
}
```
Also the content of 'menu.js' is:
```
jQuery(document).ready(function($) {
$('#toplevel_page_books li.wp-first-item').addClass('current');
});
```
---
**TL;DR**
To understand how all this works, here is a step-by-step explanation.
**Step 1:** We add the main menu item (the *books* menu item) to display the list of books
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
}
```
**Step 2:** We add the *add-book* menu item as a submenu to the main *books* menu item
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
**Step 3:** Finishing Step 2 above adds the books menu item, The menu list on the left side would look like this:
```
Books <---------- This is the main top level menu names
Books <---------- This is the first sub-menu
Add New <---------- This is the second sub-menu
```
However, we should fix this. The intended list should look like this
```
Books <---------- This is the main top level menu names
All Books <---------- This is the first sub-menu
Add New <---------- This is the second sub-menu
```
To do this, we have to modify our code as follows:
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// Adding this function to make the first submenu have a different name than the main menu
add_submenu_page('books', 'Books', 'All Books', 'publish_posts', 'books', 'render_books_page' );
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
**Step 4:** Next we should add a sub menu to edit books (the *edit-book* menu item). After adding his submenu, and when we are at the *edit-book* page, the menu on the left should look like this:
```
Books
All Books <---------- When we are in the 'edit-book' page, this menu item is selected and is highlighted (typically white in color), and also clicking on "All Books" would return us back to the "All Books" page.
Add New
```
The solution I tried first was what I posted in my original question, which did not work exactly. So, based on discussions with @Ian and looking at his proposed solution, I came up with this:
```
add_action( 'admin_menu', 'add_the_menus' );
function add_the_menus() {
// Top level menu
add_menu_page ('Books', 'Books', 'publish_posts', 'books', 'render_books_page', '', 17);
// Adding this function to make the first submenu have a different name than the main menu
add_submenu_page('books', 'Books', 'All Books', 'publish_posts', 'books', 'render_books_page' );
// If we are in the 'edit-book' page, then display the 'edit-book' submenu, otherwise, display the regular 'books' menu
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// Display the 'edit-book' menu page and display it as the 'all-books' page
// Notice that the slug is 'edit-book', but the display name is 'All Books'
add_submenu_page('books', 'Edit Book', 'All Books', 'publish_posts', 'edit-book', 'render_edit_book_page' );
}
// The add-book menu page
add_submenu_page('books', 'Add New Book', 'Add New', 'publish_posts', 'add-book', 'render_add_book_page' );
}
```
Now, if we click on the 'books' menu item, or the 'add-book' menu item, then everything is fine. However, if we try to edit an existing book then the following menu list will be displayed
```
Books
All Books <---------- This is the first sub-menu (due to the first submenu call)
All Books <---------- This is the 'edit-book' page (HIGHLIGHTED)
Add New
```
**Step 5:** Now we notice the following: By clicking on the first submenu, the "All Books" page will be rendered, and clicking on the second submenu will render the "Edit" page; and in our case, we want to render the "All Books" page.
Therefore, we have to hide the SECOND submenu and make the first submenu highlighted. This is done as follows:
```
add_action( 'admin_enqueue_scripts', function () {
if ((isset($_GET['page'])) && ($_GET['page'] === 'edit-book')) {
// Load CSS file
wp_enqueue_style('book-edit', 'path/to/css/menu.css');
// Load jQuery
wp_enqueue_script('jquery');
// Load
wp_enqueue_script('book-edit-script', 'path/to/js/menu.js');
}
});
```
And the content of `menu.css` is:
```
#toplevel_page_books li.current {
display: none;
}
#toplevel_page_books li.wp-first-item {
display: list-item;
}
```
Also the content of 'menu.js' is:
```
jQuery(document).ready(function($) {
$('#toplevel_page_books li.wp-first-item').addClass('current');
});
```
And now everything works like a charm. |

Escaping is about intent, if you intend to output a URL, use `esc_url`, and it will definately be a URL ( if the data is malicious it will be made safe )

There's no way to escape a function that outputs internally. `the_title` should be good to use, as are the others
With 1 Exception
----------------
`bloginfo`
Avoid this function at all costs, for security reasons. `bloginfo` doesn't always escape internally, and as it outputs internally there's no way to add escaping.
### The solution
Use `get_bloginfo` and escape the result, e.g.
```
<a href="<?php echo esc_url( get_bloginfo( 'site' ) ); ?>">
```
`get_bloginfo` returns rather than outputs the value, allowing us to use escaping functions.
A Brief Note on Filters
-----------------------
Sometimes you want to pass things through a filter, such as `the_content`, but escaping the result will strip out tags.
For example, this will strip any embedded videos present:
```
echo wp_kses_post( apply_filters( 'the_content', $stuff ) );
```
The solution is instead to do this:
```
echo apply_filters( 'the_content', wp_kses_post( $stuff ) );
```
The idea being that we know the input is safe, therefore the output must be safe. This assumes that any code running on that filter also escapes accordingly. Do this for these situations with WP Core filters, but avoid needing this in your own filters and code as much as possible |

I need to get all fields or custom fields in array. I found a solution [from here](https://wordpress.stackexchange.com/questions/18318/how-to-display-all-custom-fields-associated-with-a-post-type), but it does not serve my purpose:
```
echo '<pre>';
print_r(get_post_custom($post_id));

``` | Add the following code in the functions.php
**for acf**
```
function get_all_meta($type){
global $wpdb;
$result = $wpdb->get_results($wpdb->prepare(
"SELECT post_id,meta_key,meta_value FROM wp_posts,wp_postmeta WHERE post_type = %s
AND wp_posts.ID = wp_postmeta.post_id", $type

return $result;
}
function acf(){

$acf = get_all_meta('acf');
foreach($acf as $key => $value){
$options['post_type'][$value['post_id']]['post_id'] = $value['post_id'];
$test = substr($value['meta_key'], 0, 6);
if($test === 'field_'){
$post_types = maybe_unserialize( $value['meta_value'] );
$options['post_type'][$value['post_id']]['key'][] = $post_types['key'];

260,465 | <p>I'm really new to wordpress and now I have to do a plugin that creates a HTML table from file and prints it to the page, and add more functionality to the table using DataTables jquery addon. This all has to happen when i call shortcode in the page. I have managed to get the html table to the page, but i have no idea how to run jquery script to modify it.
So, in short: how to run jquery script after shortcode.
Any input is appreciated!</p>

| I'm really new to wordpress and now I have to do a plugin that creates a HTML table from file and prints it to the page, and add more functionality to the table using DataTables jquery addon. This all has to happen when i call shortcode in the page. I have managed to get the html table to the page, but i have no idea how to run jquery script to modify it.
So, in short: how to run jquery script after shortcode.
Any input is appreciated! | Your question is a little unclear. I'm interpreting it to mean that you want to enqueue a jQuery script to be run by the user's browser only on public pages that contain the shortcode.
There are (at least) three ways of running a jQuery script only on pages that have a specific shortcode. The first way is to use the `add_shortcode()` function to add a hook to `get_footer` which then enqueues the jQuery script in the footer.
```
//* Enqueue script in the footer
function wpse_260465_enqueue_script() {
wp_enqueue_script( 'your-style-id', PATH_TO . 'script.js', [ 'jquery' ], false, true );
}
//* Add action to enqueue script in the footer and return shortcode value
function wpse_260465_shortcode( $atts ) {
add_action( 'get_footer', 'wpse_260465_enqueue_script' );
return 'your shortcode content';
}
add_shortcode( 'wpse_260465', 'wpse_260465_shortcode' );
```
The second way registers the script on every page, but only enqueues it when the specific shortcode is called on a page.
```
//* Enqueue previously registered script and return shortcode value
function wpse_260465_shortcode( $atts ) {
wp_enqueue_script( 'your-style-id' );
return 'your shortcode content';
}
add_shortcode( 'wpse_260465', 'wpse_260465_shortcode' );
//* Register our script to maybe enqueue later
add_action( 'wp_enqueue_scripts', 'wpse_260465_enqueue_scripts' );
function wpse_260465_enqueue_scripts() {
wp_register_script( 'your-style-id', PATH_TO . 'script.js', [ 'jquery' ], false, true );
}
```
The third way is to simply use the `add_shortcode()` function to write the jQuery inline.
```
//* Return inline jQuery script with shortcode value
function wpse_260465_shortcode( $atts ) {
$your_shortcode_content = 'your shortcode content';
$your_shortcode_content .= $your_inline_jquery;
return $your_shortcode_content;
}
add_shortcode( 'wpse_260465', 'wpse_260465_shortcode' );
```

Thanks for any help! | If your goal is to put it in the `<head>IM INSIDE THE HEAD</head>` tag than just put it inside the head tag in the `theme_header.php` or `header.php` of your theme – if it's not a child theme.
Place this snippet of code directly above the closing `</head>` tag in your header.php file.
```
<?php
if ( is_checkout() || is_cart() ) {
// Add meta tag here
echo '<meta name="yo:active" content="false">';
}
?>
```
Should work fine for you. |

"text": "<p>I think the answer by @Fayaz is very good; they are definitely on the right path in that you should use sprintf() wrapped around translations to include things such as HTML and links.</p>\n\n<p>However, I don't believe that it is a good idea to split sentences into parts for translation, as many languages have different sentence structures that are not at all compatible with English. By splitting out individual words, a great deal of the context in which a specific word is translated is lot, potentially leading to ambiguity and translation errors.</p>\n\n<p>Instead, I recommend translating phrases and sentences as a whole, and then using <code>sprintf</code> or different esccaping functions where appropriate.</p>\n\n<p>For your text, the first part can simply be translated by itself with <code>esc_html_e</code>:</p>\n\n<pre><code>esc_html_e( 'Dear Guest, with your information we not find any room at the moment.

Now, I assume that you are retrieving the page URL and email from the database somehow, probably using <code>get_the_permalink()</code> or <code>get_option()</code> or some other function. So I'm going to assume they are stored in <code>$contact_page_url</code> and <code>$contact_email</code> variables.</p>\n\n<p>The first step is to translate the string, without the links.

Note that we use <code>esc_url()</code> here to escape the URL, and also the <code>antispambot()</code> to encode the email address to provide a minimal protection against scrapers:</p>\n\n<pre><code>$text = sprintf(\n __( 'Please contact us on our <a href=\"%1$s\">contact page</a> or by email %2$s.', 'text-domain' );\n esc_url( $contact_page_url ),\n sprintf( '<a href=\"mailto:%1$s\">%1$s</a>', antispambot( $contact_email ) );\n);\n</code></pre>\n\n<p>Finally, rather than using <code>esc_html()</code> , we need to use <code>wp_kses()</code> to only allow link elements in the translated HTML:</p>\n\n<pre><code>echo wp_kses( $text, array( 'a' => array( 'href' => array() ) ) );\n</code></pre>\n\n<p>And that's it!

| I am somewhat new in WordPress if it is about "deeper" customization.
Now I am having this function:
```
esc_html_e( 'Dear Guest, with Your information we not find any room at the moment. Please contact us per email [email protected].', 'awebooking' );
```
And the text is showing so far.
But what *function* do I need to use when I like to add an `a` `href` (HTML link)?
So I like to have this text:
>
> Dear Guest, with Your information we not find any room at the moment.
>
>
> Please contact us on our `<a href="http://www.whitesandsamuiresort.com/contact-us/">contact page</a>` or per email `[email protected]`.

I'm having problem supporting translation (internationalization / localization) and escaping HTML links at the same time. | Since [`esc_html_e`](https://developer.wordpress.org/reference/functions/esc_html_e/) will escape HTML link (hence will show the HTML anchor as plain text), you'll need to segment the text and escape the non-HTML part with `esc_html_e` or [`esc_html__`](https://developer.wordpress.org/reference/functions/esc_html__/), and print the HTML LINK part without HTML escaping.
Method-1 (just for your understanding):
=======================================
You may do it in parts, like this:
```
esc_html_e( 'Dear Guest, with Your information we could not find any room at the moment.', 'text-domain' );
echo "<br><br>";
printf(
esc_html__( '%1$s %2$s', 'text-domain' ),
esc_html__( 'Please contact us on our', 'text-domain' ),
sprintf(
'<a href="%s">%s</a>',
esc_url( 'http://www.example.com/contact-us/' ),
esc_html__( 'Contact Page', 'text-domain' )
)
);
printf(
' or <a href="%s">%s</a>',
esc_url( 'mailto:[email protected]', array( 'mailto' ) ),
esc_html__( 'Email', 'text-domain' )
);
```
Method-2 (just for your understanding):
=======================================
Obviously, different languages will have different ordering of texts, so to give translators more flexibility (with escaping and ordering of text), you may do it in the following way instead:
```
printf(
esc_html__( '%1$s%2$s%3$s%4$s%5$s', 'text-domain' ),
esc_html__( 'Dear Guest, with Your information we could not find any room at the moment.', 'text-domain' ),
nl2br( esc_html__( "\n\n", 'text-domain' ) ),
sprintf(
esc_html__( '%1$s %2$s', 'text-domain' ),
esc_html__( 'Please contact us on our', 'text-domain' ),
sprintf(
'<a href="%s">%s</a>',
esc_url( 'http://www.example.com/contact-us/' ),
esc_html__( 'Contact Page', 'text-domain' )
)
),
esc_html__( ' or ', 'text-domain' ),
sprintf(
'<a href="%s">%s</a>',
esc_url( 'mailto:[email protected]', array( 'mailto' ) ),
esc_html__( 'Email', 'text-domain' )
)
);
```
This way of doing it will:
1. Escape all the necessary translated texts.
2. Allow the HTML for link, email (with `mailto:` syntax) etc.
3. Allow translators to have all sorts of different ordering of texts for different languages. The [argument swapping notation](http://php.net/manual/en/function.sprintf.php#example-5474) (`%1$s`, `%2$s` etc.) is used so that the translators may reorder the translated text where needed.
---
Method-3 (Updated & Recommended):
=================================
As [@shea rightly pointed out](https://wordpress.stackexchange.com/a/261374/110572), **Method-2** above works fine, but it may be difficult for the translators to add support for different languages. So we need a solution that:
1. Keeps the sentences intact (doesn't break sentences).
2. Does proper escaping.
3. Provides ways to have different ordering for contact & email links (or anything similar) within the translated sentence.
So to avoid the complication of **method-2**, the solution below keeps the translatable sentences intact and does the proper URL escaping & argument swapping at the same time (more notes within CODE comments):
```
// sample contact url (may be from an unsafe place like user input)
$contact_url = 'http://www.example.com/contact-us/';
// escaping $contact_url
$contact_url = esc_url( $contact_url );
// sample contact email (may be from an unsafe place like user input)
$contact_email = '[email protected]';
// escaping, sanitizing & hiding $contact_email.
// Yes, you may still need to sanitize & escape email while using antispambot() function
$contact_email = esc_url( sprintf( 'mailto:%s', antispambot( sanitize_email( $contact_email ) ) ), array( 'mailto' ) );
esc_html_e( 'Dear Guest, with Your information we could not find any room at the moment.', 'text-domain' );
echo "<br><br>";
printf(
esc_html__( 'Please contact us on our %1$s or per %2$s.', 'text-domain' ),
sprintf(
'<a href="%s">%s</a>',
$contact_url,
esc_html__( 'Contact Page', 'text-domain' )
),
sprintf(
'<a href="%s">%s</a>',
$contact_email,
esc_html__( 'Email', 'text-domain' )
)
);
```
This way of doing it will give translators two full sentences & two separate words to translate. So a translators will only have to worry about the following simple lines (while the CODE takes care of the rest):
```
esc_html_e( 'Dear Guest, with Your information we could not find any room at the moment.', 'text-domain' );
// ...
esc_html__( 'Please contact us on our %1$s or per %2$s', 'text-domain' )
// ...
esc_html__( 'Contact Page', 'text-domain' )
// ...
esc_html__( 'Email', 'text-domain' )
```
That's it, simple structure and does proper escaping and argument swapping as well.

260,519 | <p>I want to be able to detect if a file at a certain path is a WordPress generated thumbnail. The only distinguishing feature of the WordPress thumbnail, as far as individual files are concerned, is that it would end with two or three numbers, 'x', another two or three numbers and then the file extension. The only way I can think of doing this would be to use a regex to literally detect that pattern in the file name. Is there a better way that I'm not thinking of? If not can someone help me with the regex?</p>

Is there is a way to do it? | The following is **not** a *complete* solution (i.e., as @cjbj mentioned, it won't handle links in post content), but it will achieve what you want for any link whose URL is obtained (in WP Core, a theme or a plugin) via [get\_permalink()](https://developer.wordpress.org/reference/functions/get_permalink/) (including the output of [wp\_page\_menu()](https://developer.wordpress.org/reference/functions/wp_page_menu/), and kin).
```
$filters = array (
'post_link', // when post_type == 'post'

Explanation
-----------
Before returning it's result, `get_permalink()` applies one of 4 filters (named in the `$filters` array above) on the permalink it has generated. So, we hook into each of those filters.
The function we hook to these filters calls [add\_query\_arg()](https://developer.wordpress.org/reference/functions/add_query_arg/) to add any query args present in the current request (i.e., `$_GET`).
Important Security Consideration
--------------------------------
As mentioned in [add\_query\_arg()](https://developer.wordpress.org/reference/functions/add_query_arg/):
>
> Important: The return value of add\_query\_arg() is not escaped by default. Output should be late-escaped with esc\_url() or similar to help prevent vulnerability to cross-site scripting (XSS) attacks.
>
>
>
Calling esc\_url() in `wpse_add_current_requests_query_args()` is not what I would call "late-escaped" in all cases. But unfortunately, a number of WP Core funcs (e.g. [Walker\_Page::start\_el()](https://developer.wordpress.org/reference/classes/walker_page/start_el/), which is ultimately called by `wp_page_menu()`), don't call `esc_url()` on the return value of `get_permalink()`, so we have to call it in our filter hook to be safe. |

260,652 | <p>I originally installed wordpress in a subdirectory called /blog. Today I decided to change the URL of my site to remove the /blog element from the URL e.g. from www.mywebsite.com/blog to www.mywebsite.com. Here is what I did:</p>
<ol>
<li>went to settings > general and changed the site address:</li>
</ol>
<p>WordPress Address (URL): www.mywebsite.com/blog</p>
<p>Site Address (URL): www.mywebsite.com</p>
<ol start="2">
<li><p>deleted my original homepage (index.html)</p></li>
<li><p>downloaded the index.php file from the /blog directory, and uploaded a copy into the root directory</p></li>
<li><p>opened the index.php file from the root directory and changed the following line of code:</p></li>
</ol>
<p><strike>require( dirname( <strong>FILE</strong> ) . '/wp-blog-header.php' );</strike></p>
<pre><code> require( dirname( __FILE__ ) . '/blog/wp-blog-header.php' );
</code></pre>
<p>This worked in that I now landed directly on my wordpress blog when I typed in www.mywebsite.com, but all my internal links resulted in 404 errors. So I changed my permalinks to plain (e.g. wwww.mywebsite.com/?p=123), which fixed the broken links. However, I prefer to use the post name structure (e.g. wwww.mywebsite.com/name-of-post) so tried to fix this by doing the following:</p>
<ol start="5">
<li><p>created a file called .htaccess in the root directory, and typed in the following code:</p>
<pre><code># BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
</code></pre></li>
</ol>
<p>This went horribly wrong, resulting in 500 errors that locked my out of the WP dashboard for some time. I can't remember exactly how I fixed this, but the only other change I made was as follows:</p>
<ol start="6">
<li><p>edited web.config file in /blog directory:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="WordPress Rule" stopProcessing="true">
<match url=".*" />
<conditions>

</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>"
</code></pre></li>
</ol>
<p>This still didn't allow post name permalinks, so I set permalinks back to plain. However, I now have a weird situation where about half of my internal links work okay, and the other half result in 404's. I don't really understand how this is possible, as I would have thought it would be all or nothing!</p>
<p>Can anyone please help?</p>
<p>UPDATE - NOW RESOLVED (YAY!):
After struggling to fix this, I contacted the support helpline for the company that provides my web hosting. They said that the fact I was on a windows server was problematic, as it is not really compatible with WordPress. So this is what I / they did:</p>
<ol>
<li>phoned my web host providers and changed to a LINUX server</li>
<li>downloaded the free FTP application FileZilla, and imported all of my wordpress files onto my computer. I then transferred them via FTP to the new LINUX server, into the root directory (public_html).</li>
<li>exported my WordPress database from the old windows server and saved onto my computer. I then created a new database in the new LINUX server and imported the WordPress database (I have to admit something went wrong here, so the support guys ended up doing this for me)</li>
<li>my web host provider then pushed the LINUX site live (again, something went wrong here so another phone call was involved in getting them to fix the problem).</li>
<li>Used the plug-in 'Velvet Blues Update URLs' to update all instances of www.mywebsite.com/blog to www.mywebsite.com in posts, links and attachments (i.e. images were not displayed until I did this)</li>
<li>turned on permalinks and checked it worked</li>
</ol>
<p>This was a bit of a palava, but got there in the end. I'm sure there are much easier ways to achieve this, but I'm posting this solution just so non-technical people like myself realise they can call the helpline for their web hosting platform rather than trying to struggle through.</p>

| I would like to limit the +New admin menu to only show the single sub menu Event ("Veranstaltung").
Basically the users are allowed to create other items as well but not from that +New menu.
[](https://i.stack.imgur.com/mNFRB.png)
I already tried it with "Adminimize" plugin as this can remove the other items but it will leave the new media link intact once you click directly "+New".

```
function remove_menus() {
remove_menu_page('edit.php?post_type=mdocs-posts');
}

But I can't get how to modify the +New. Any hints?
Thank you! | **To hide everything (menu and submenu)-**
```
function wpse_260669_remove_new_content(){
global $wp_admin_bar;
$wp_admin_bar->remove_menu( 'new-content' );
}
add_action( 'wp_before_admin_bar_render', 'wpse_260669_remove_new_content' );
```
**To hide specific menu/submenu item(s)-**
```
function wpse_260669_remove_new_content_items(){
global $wp_admin_bar;
$wp_admin_bar->remove_menu( 'new-post' ); // hides post CPT
$wp_admin_bar->remove_menu( 'new-product' ); // hides product CPT
$wp_admin_bar->remove_menu( 'new-page' ); // hides page CPT
$wp_admin_bar->remove_menu( 'new-media' ); // hides media
}
add_action( 'wp_before_admin_bar_render', 'wpse_260669_remove_new_content_items' );
```
**So, the basic rule is-**
```
function your_boo_bar_function() {
global $wp_admin_bar;
$wp_admin_bar->remove_menu( 'your-unique-menu-id' );
}
add_action( 'wp_before_admin_bar_render', 'your_boo_bar_function' );
```
**Add a new menu-**
```
function wpse_260669_add_menu(){
global $wp_admin_bar;
$wp_admin_bar->add_node(
array(
'id' => 'google-menu',
'title' => 'Google',
'href' => 'http://google.com',
'parent' => 'new-content', // so, it'll be set as a child of 'new-content'. remove this to use this as a parent menu
'meta' => array( 'class' => 'my-custom-class' ),
)
);
}
add_action( 'wp_before_admin_bar_render', 'wpse_260669_add_menu' );
```
**Update an existing menu-**
If you want to update an existing menu item, just add a new item using the ID of your desired menu.
To update +New ('content-new'), use this code-
```
function wpse_260669_update_menu(){
global $wp_admin_bar;
$wp_admin_bar->add_node(
array(
'id' => 'new-content', // id of an existing menu
'href' => 'your_new_url_goes_here', // set new URL
)
);
}
add_action( 'wp_before_admin_bar_render', 'wpse_260669_update_menu' );
```
**How to get menu ID-**
The easiest way is to inspect element with Firebug and take the ID. See this screenshot-
[](https://i.stack.imgur.com/X4DMA.jpg)

260,713 | <p>Working on a site that has a lot of posts, I need to display 3 posts from a particular category, but all of them need to be from the latest 10 published on the site. I can either grab 3 completely random posts (which tends to pull posts that are very old) or grab 10 posts (but I don't know how to then randomize the order and only display 3).</p>
<p>So far, I have this query:</p>
<pre><code>$args = array(
'post_type' => 'post',
'category_name' => 'mycategory',
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC',
'meta_key' => '_thumbnail_id',
'no_found_rows' => 'true'
);
$query = new WP_Query( $args );
</code></pre>
<p>along with this attempt to get 3 random posts from the 10 queried:</p>
<pre><code>$randomPosts = shuffle( $query );
$randomPosts = array_slice( $randomPosts, 0, 3 );
</code></pre>
<p>But treating the results as an array doesn't work, since it's actually an object.<br />
My only other thought is to use <code>'posts_per_page' = 3</code> with <code>'orderby' => 'rand'</code> to grab 3 random posts and add a <code>'date_query'</code> to restrict it to the past 6 months. That would be close, but it would be preferable to restrict the query to the 10 most recent posts (they may all be published 3 days ago or 5 months ago, they are published together in uneven spurts).</p>
<p>What is the best approach?<br />
Query the 10 latest posts as I'm doing, then convert the object to an array, shuffle, and slice, and convert it back to an object, or is there a simpler, more efficient way to accomplish the goal?</p>

| Working on a site that has a lot of posts, I need to display 3 posts from a particular category, but all of them need to be from the latest 10 published on the site. I can either grab 3 completely random posts (which tends to pull posts that are very old) or grab 10 posts (but I don't know how to then randomize the order and only display 3).
So far, I have this query:
```
$args = array(
'post_type' => 'post',
'category_name' => 'mycategory',
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC',
'meta_key' => '_thumbnail_id',
'no_found_rows' => 'true'
);
$query = new WP_Query( $args );
```
along with this attempt to get 3 random posts from the 10 queried:
```
$randomPosts = shuffle( $query );
$randomPosts = array_slice( $randomPosts, 0, 3 );
```
But treating the results as an array doesn't work, since it's actually an object.
My only other thought is to use `'posts_per_page' = 3` with `'orderby' => 'rand'` to grab 3 random posts and add a `'date_query'` to restrict it to the past 6 months. That would be close, but it would be preferable to restrict the query to the 10 most recent posts (they may all be published 3 days ago or 5 months ago, they are published together in uneven spurts).
What is the best approach?
Query the 10 latest posts as I'm doing, then convert the object to an array, shuffle, and slice, and convert it back to an object, or is there a simpler, more efficient way to accomplish the goal? | There's one way with:
```
$args = [
'post_type' => 'post',
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC',
'no_found_rows' => 'true',
'_shuffle_and_pick' => 3 // <-- our custom argument
];
$query = new \WP_Query( $args );
```
where the custom `_shuffle_and_pick` attribute is supported by this demo plugin:
```
<?php
/**
* Plugin Name: Support for the _shuffle_and_pick WP_Query argument.
*/
add_filter( 'the_posts', function( $posts, \WP_Query $query )
{
if( $pick = $query->get( '_shuffle_and_pick' ) )
{
shuffle( $posts );
$posts = array_slice( $posts, 0, (int) $pick );
}
return $posts;
}, 10, 2 );

| So i'm adding a script into my site via `functions.php` that lives in the plugins directory. The code is pretty straightforward:
```
function add_jq_script() {
wp_register_script('r_footer', plugins_url('/responsiveFooter.js', __FILE__), array('jquery'),'1.1', true);
wp_enqueue_script('r_footer');
}
add_action( 'wp_enqueue_scripts', 'add_jq_script', 999 );
```
the plugins seem to be working on local site, but in dev console, i'm getting a 404 that seems to be concatting my site-url and the absolute url for my plugins:
`http://localhost/~thisuser/wordpress/wp-content/plugins/Users/thisuser/Sites/wordpress/wp-content/themes/liberty/responsiveFooter.js?ver=1.1`
i'm a bit new to wordpress, the url should be `http://localhost/~thisuser/wordpress/wp-content/plugins/responsiveFooter.js`
is there some wp-option i need to change or some plugin setting somewhere to fix this? | `plugins_url` will output the absolute file path of the plugins directory in your WordPress install.
This of course won't work for a client (browser) calling a script.
To access scripts from the plugins directory, you'll want to use `plugin_dir_url()` which will get you the url of the plugin directory.
**Some things to note about `plugin_dir_url()`**
* You need to specify the directory of the plugin name your script is located
* The function output contains a trailing slash, so you won't need to concatenate a slash.
Lets say your plugin is called "my\_plugin" and the script is located in a "js" directory, your script registration would look something like this:
```
wp_register_script('r_footer', plugins_dir_url() . 'my_plugin/js/responsiveFooter.js', array('jquery'),'1.1', true);
```
Note the omission of `__FILE__` which will output the absolute path of the current file (not what you want).
---
If your script is in your active theme, you'll want to use a different function: `get_stylesheet_directory_uri`
**Some things to note about `get_stylesheet_directory_uri`**
* It requires a trailing slash unlike `plugin_dir_url()`
* You will need to specify the directory path in the theme where your script is located.
* This function works especially well if you are working with child themes, but a child theme is not required. If you are working with a child theme, this function will get the path to the style.css file in your child theme rather than the parent theme.
* Note that the function is ur**i** NOT ur**l**
So lets say your theme is called "my\_theme" and the javascript is located in a "js" file, your registration script would look something like this:
```
wp_register_script('r_footer', get_stylesheet_directory_uri() . '/my_theme/js/responsiveFooter.js', array('jquery'),'1.1', true);
```

It won't identify standard theme files such as index.php, single.php, header.php, footer.php, because those are not custom Page templates. And it's best practice to include index.php, since it is a default/fallback if there is ever a problem with more specific theme files. In many cases the file is never used, but it's always good to have it there, and it usually shows you the barebones HTML structure of the site, which can be a helpful cue before you dive into more customized files.</p>\n\n<p>If you want to continue down the reverse-engineering path, I would suggest including your theme-file-identifier code in the (as a comment if it's a live site) and manually go through each URL. If you use a plugin that generates an XML sitemap it can help you ensure that you hit every URL. Just bear in mind that whatever file is identified is probably not the only file in use. For example, if your Posts use the default <code>single.php</code> it is very likely to be making use of <code>header.php</code> and <code>footer.php</code> at a minimum. Some themes use template parts or includes, so after you have your initial list of the overarching template used on each URL, you will have to look through each of those templates and determine which files they call. You'll also want to check <code>functions.php</code> for the enqueued stylesheets and JS, as well as potentially other includes.</p>\n\n<p>One alternative to this long process is to rebuild the theme from the ground up. I understand this isn't always possible, but it's the cleanest solution, and it's likely to take less time and be less risky than trying to slowly slough off parts of an old complex theme. For this process, I identify the most-used templates (if you have 50 of one CPT start there) and code those first on a dev/staging site, import or copy at least a handful of each post type and keep building from there. Once again you'll need to go through at least most of the site to make sure you don't overlook customizations, and the only way you'll be 100% certain you caught everything is to review every URL.</p>\n"

Thanks | Here's a rough function I use to handle this, it should work well for anyone out there wanting to do this quick and easy. Add this this your functions.php file and then visit your site with `?template_report` added onto the URL to display a report for every custom theme template.
**It's rough, I'd suggest commenting/uncommenting the `add_action` call when you want to use it.**
```
/**
* Theme Template Usage Report
*
* Displays a data dump to show you the pages in your WordPress
* site that are using custom theme templates.
*/
function theme_template_usage_report( $file = false ) {
if ( ! isset( $_GET['template_report'] ) ) return;
$templates = wp_get_theme()->get_page_templates();
$report = array();
echo '<h1>Page Template Usage Report</h1>';
echo "<p>This report will show you any pages in your WordPress site that are using one of your theme's custom templates.</p>";
foreach ( $templates as $file => $name ) {
$q = new WP_Query( array(
'post_type' => 'page',
'posts_per_page' => -1,
'meta_query' => array( array(
'key' => '_wp_page_template',
'value' => $file
) )
) );
$page_count = sizeof( $q->posts );
if ( $page_count > 0 ) {
echo '<p style="color:green">' . $file . ': <strong>' . sizeof( $q->posts ) . '</strong> pages are using this template:</p>';
echo "<ul>";
foreach ( $q->posts as $p ) {
echo '<li><a href="' . get_permalink( $p, false ) . '">' . $p->post_title . '</a></li>';
}
echo "</ul>";
} else {
echo '<p style="color:red">' . $file . ': <strong>0</strong> pages are using this template, you should be able to safely delete it from your theme.</p>';
}
foreach ( $q->posts as $p ) {
$report[$file][$p->ID] = $p->post_title;
}
}
exit;
}
add_action( 'wp', 'theme_template_usage_report' );
```
The output looks like this:

| Say I have a user meta field that is called "meta1".
I want to get posts (via get\_posts or the like) who's author meta1 = true.
Any idea how I should approach this? | Get for all users / authors with user meta field. `meta1 = true`
```
$args = array(
'meta_key' => 'meta1',
'meta_value' => 'true',
'meta_compare' => '=',
'fields' => 'all',
);
$users = get_users( $args );
```
Store user id and login into an array `authors`
```
$authors = array();
foreach ( (array) $users as $user ) {
authors[ $user->ID ] = $user->user_login;
}
```
Now you can pass authors in your posts query.
```
$posts = query_posts( array( 'author__in'=> array_keys( $authors ) ) );
```
**Or**
```
$posts = new WP_Query( array( 'author__in' => array( array_keys( $authors ) ) );
```

```
$args = array(
'meta_key' => 'meta1',
'meta_value' => 'true',
'meta_compare' => '=',

$users = get_users( $args );

foreach ( (array) $users as $user ) {
$authors[ $user->ID ] = $user->user_login;
}

// now check if the query has posts and if so, output their content in a banner-box div

<?php while ( $get_banner->have_posts() ) : $get_banner->the_post(); ?>

<?php endwhile; ?>
<?php }
wp_reset_postdata();
}
?>
```
**UPDATE**
As you're using it inside a plugin. You can do like the following:
```
<?php
// function to show home page banner using query of banner post type
function wptutsplus_home_page_banner() {
// start by setting up the query
$get_banner = new WP_Query( array(
'post_type' => 'banners',
'meta_query' => array(
array(
'key' => 'banner_link',
'value' => 'https://www.mypage.com'
)
)
));
// now check if the query has posts and if so, output their content in a banner-box div
if ( $get_banner->have_posts() ) : while ( $get_banner->have_posts() ) : $get_banner->the_post();
$output = '<div class="container" align="center"><a href="'.get_post_meta( $post->ID, 'banner_link', true ).'">'.get_the_post_thumbnail().'</a></div>';
endwhile;
endif;
wp_reset_postdata();
return $output;
}
?>
```
And then call it anywhere with `<?php echo wptutsplus_home_page_banner(); ?>`
Let me know if it works. |

Problem is, whatever I try using it in my query, it prints a SQL error.
What I tried to do is a little more complex than what I'll show you, but I progressively simplified my query to see where the error could come from, but never found.

Is it an issue with my installation, or something I missed ? I could use some help on this. | its a syntax error according to error message. starements like below might work for you.

So, I need to be able to add some code at the exact place above where I have **(code placeholder spot which I will reference later)** which will insert anything I want as the first row of the array.
I want to be able add a custom row, for example, "id, name, date" so that when I run the display code it will display this:

I've tried a few things I've found online but nothing seems to work.
And no, a simple 'echo' command won't do. I don't want to go into details why (because it will make this post very long), but in my case I need the custom row added to the array.
Please help!

If the `.htaccess` has been compromised, do you have any suggestions for securing it?
I did a fresh WordPress install, updated/reinstalled all plugins, reset passwords, installed captchas for logins, moved the WordPress install to a different directory, etc. Website seemed to be fine for a few days, but was hacked again. So frustrating! | ### About Hacked sites:
First of all, let's be clear about issues related to hacking:
>
> If your site was genuinely hacked, then in short of completely erasing all the files and then reinstalling the server (not just WordPress) with new passwords, updating all files and identifying and removing previous loop holes that caused the site to be hacked in the first place, nothing else will confirm that the site will not be hacked again using the same loop holes.
>

>
### About the `.htaccess` modification:
To me, your `.htaccess` modification doesn't look like the result of hacking, instead it looks like a piece of WordPress CODE (either from a Plugin, or theme) that is rewriting the `.htaccess` file because of URL rewrites.
Check out this sample from your `.htaccess` CODE:
```
RewriteRule ^([^\d\/]+)-([0-9]+)-([0-9]+)-.*..*$ ?$1$3=$2&%{QUERY_STRING}[L]
```
This line is basically transforming a URL that looks like this (for example):
```
example.com/something-12-34-something-else.html?query=string
```
to adds query string (internally to the main `index.php`) that looks like this:
```
?something34=12&query=string
```
So, basically I don't see how a hacker will gain anything from this. It's still possible, but unlikely.
To test it is indeed being rewritten by WordPress this way, you may do the following test:
1. Go to `wp-admin -> Settings -> Permalinks` & click `Save Changes` button.
2. Rewrite `.htaccess` with the default WordPress `.htaccess` CODE.
3. Now, go to `wp-admin -> Settings -> Permalinks` again and click `Save Changes` button.
If your `.htaccess` file is writable by WordPress (web server) and if that `.htaccess` CODE was being generated by WordPress, then after the above process, your default WordPress `.htaccess` will be changed immediately to the one you've posted.
### What to do next?
If you've successfully identified the changes to be made by WordPress, then you may detect which plugin or theme is doing it, by again following the above procedure after disabling each installed plugin one at a time.
Once the responsible plugin is disabled, the above procedure will not produce that change in the `.htaccess` file anymore. Then you'll know which plugin is doing it, and perhaps will have a better understanding of why it's doing it. e.g. whether it is a feature or the result of malicious activity.
If no plugin is found to be doing it, then you may do the same with the theme by activating a WordPress core theme (e.g. Twenty Seventeen).
If none of the above works, then I guess your next option is to hire an expert and allow him to examine your site. |

| We all know that `ignore_sticky_posts` is used to exclude sticky post from your custom query.
But why on [WordPress Theme Development documentation](https://developer.wordpress.org/themes/functionality/sticky-posts/), they use `ignore_sticky_posts` in querying sticky posts?
```php
$args = array(
'posts_per_page' => 1,
'post__in' => get_option( 'sticky_posts' ),
'ignore_sticky_posts' => 1
);
$query = new WP_Query( $args );
```
This is so confusing and doesn't make any sense! You want it and yet you exclude it? | >
> We all know that `ignore_sticky_posts` is used to exclude sticky post from your custom query.

### - No, this assumption is wrong.
---
What `ignore_sticky_posts` means:
---------------------------------
Even though in natural English, `ignore_sticky_posts` sounds like WordPress should ignore all sticky posts from the query, in reality that is not what WordPress does. Instead, you should read `'ignore_sticky_posts' => 1` argument as follows:
>
> When `ignore_sticky_posts` is set to `true` or `1`, WordPress will **ignore the procedure** of setting the sticky posts within your custom query.
>
>
>
---
What WordPress does when `ignore_sticky_posts` is not set:
----------------------------------------------------------
To clearly understand what `'ignore_sticky_posts' => 1` does, you need to understand what WordPress does when `ignore_sticky_posts` argument is not set or it's set to `false` or `0` (by default):
1. If there are posts within the query result that are part of stick posts, WordPress will push them to the top of the query result.
2. If any sticky post is not present within the query result, WordPress will get all those sticky posts from the database again and set them to the top of the query result.
So when the argument is set as `'ignore_sticky_posts' => 1`, WordPress simply **ignores the above procedure**, that's all. It doesn't exclude them specifically. For that you need to set `post__not_in` argument.
---
Explanation of the codex example:
---------------------------------
Now, let's come to the example from the codex:
```
$args = array(
'posts_per_page' => 1,
'post__in' => get_option( 'sticky_posts' ),
'ignore_sticky_posts' => 1
);
$query = new WP_Query( $args );
```
Here codex is only setting `'ignore_sticky_posts' => 1` **to be efficient, nothing more**. Even without having it, you will get the same expected result:
```
$args = array(
'posts_per_page' => 1,
'post__in' => get_option( 'sticky_posts' )
);
$query = new WP_Query( $args );
```
However, in this case, since `'ignore_sticky_posts' => 1` argument is not set, WordPress will needlessly do all those procedure of setting sticky posts to the top of the results, even though all of these results (from this example) are only sticky posts.

| I'd like to limit search to characters used on the English language + numbers.
The reason is that looking at the slowest queries on mysql log i found most come from searches in Arab, Russian and Chinese characters, so i'd like to skip them and display an error message instead. | This solution filters search strings by applying a regular expression which only matches characters from the Common and Latin Unicode scripts.
---
Matching Latin Characters with Regular Expressions
--------------------------------------------------
I just [had my mind blown over at Stack Overflow](https://stackoverflow.com/questions/43015495). As it turns out, regular expressions have [a mechanism](http://www.regular-expressions.info/unicode.html#script) to match entire Unicode categories, including values to specify entire [Unicode "scripts"](https://wikipedia.org/wiki/Script_(Unicode)), each corresponding to groups of characters used in different writing systems.
This is done by using the `\p` meta-character followed by a Unicode category identifier in curly braces - so `[\p{Common}\p{Latin}]` matches a single character in either the [Latin or Common scripts](https://wikipedia.org/wiki/List_of_Unicode_characters#Latin_script) - this includes punctuation, numerals, and miscellaneous symbols.
As [@Paul 'Sparrow Hawk' Biron points out](https://wordpress.stackexchange.com/a/261430/25324), the `u` [pattern modifier flag](http://php.net/manual/en/reference.pcre.pattern.modifiers.php) should be set at the end of the regular expression in order for PHP's PCRE functions to treat the subject string as `UTF-8` Unicode encoded.
All together then, the pattern
```
/^[\p{Latin}\p{Common}]+$/u
```
will match an entire string composed of one or more characters in the Latin and Common Unicode scripts.
---
Filtering the Search String
---------------------------
A good place to intercept a search string is [the `pre_get_posts` action](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) as it fires immediately before WordPress executes the query. With **more care**, this could also be accomplished using [a `request` filter](https://codex.wordpress.org/Plugin_API/Filter_Reference/request).
```
function wpse261038_validate_search_characters( $query ) {
// Leave admin, non-main query, and non-search queries alone
if( is_admin() || !$query->is_main_query() || !$query->is_seach() )
return;
// Check if the search string contains only Latin/Common Unicode characters
$match_result = preg_match( '/^[\p{Latin}\p{Common}]+$/u', $query->get( 's' ) );
// If the search string only contains Latin/Common characters, let it continue
if( 1 === $match_result )
return;
// If execution reaches this point, the search string contains non-Latin characters
//TODO: Handle non-Latin search strings
//TODO: Set up logic to display error message
}
add_action( 'pre_get_posts', 'wpse261038_validate_search_characters' );
```
---
Responding to Disallowed Searches
---------------------------------
Once it's been determined that a search string contains non-Latin characters, you can use `WP_Query::set()` in order to modify the query by changing it's named [query vars](https://codex.wordpress.org/WordPress_Query_Vars) - thus affecting the SQL query WordPress subsequently composes and executes.
The most relevant query variables are probably the following:
* `s` is the query variable corresponding to a search string. Setting it to `null` or an empty string (`''`) will result in the WordPress no longer treating the query as a search - often times this results in an archive template displaying all posts or the front-page of the site, depending on the values of the other query vars. Setting it to a single space (`' '`), however, will result in WordPress recognizing it as a search, and thus attempting to display the `search.php` template.
* `page_id` could be used to direct the user to a specific page of your choice.
* `post__in` can restrict the query to a specific selection of posts. By setting it to an array with an impossible post ID, [it can serve as a measure to ensure that the query returns absolutely nothing](https://wordpress.stackexchange.com/questions/140692/can-i-force-wp-query-to-return-no-results).
The above in mind, you might do the following in order to respond to a bad search by loading the `search.php` template with no results:
```
function wpse261038_validate_search_characters( $query ) {
// Leave admin, non-main query, and non-search queries alone
if( is_admin() || !$query->is_main_query() || !$query->is_seach() )
return;
// Check if the search string contains only Latin/Common Unicode characters
$match_result = preg_match( '/^[\p{Latin}\p{Common}]+$/u', $query->get( 's' ) );
// If the search string only contains Latin/Common characters, let it continue
if( 1 === $match_result )
return;
$query->set( 's', ' ' ); // Replace the non-latin search with an empty one
$query->set( 'post__in', array(0) ); // Make sure no post is ever returned
//TODO: Set up logic to display error message
}
add_action( 'pre_get_posts', 'wpse261038_validate_search_characters' );
```
---
Displaying an Error
-------------------
The way in which you actually display the error message is highly dependent on your application and the abilities of your theme - there are many ways which this can be done. If your theme calls `get_search_form()` in it's search template, the easiest solution is probably to use a [`pre_get_search_form` action](https://developer.wordpress.org/reference/hooks/pre_get_search_form/) hook to output your error immediately above the search form:
```
function wpse261038_validate_search_characters( $query ) {
// Leave admin, non-main query, and non-search queries alone
if( is_admin() || !$query->is_main_query() || !$query->is_seach() )
return;
// Check if the search string contains only Latin/Common Unicode characters
$match_result = preg_match( '/^[\p{Latin}\p{Common}]+$/u', $query->get( 's' ) );
// If the search string only contains Latin/Common characters, let it continue
if( 1 === $match_result )
return;
$query->set( 's', ' ' ); // Replace the non-latin search with an empty one
$query->set( 'post__in', array(0) ); // Make sure no post is ever returned
add_action( 'pre_get_search_form', 'wpse261038_display_search_error' );
}
add_action( 'pre_get_posts', 'wpse261038_validate_search_characters' );
function wpse261038_display_search_error() {
echo '<div class="notice notice-error"><p>Your search could not be completed as it contains characters from non-Latin alphabets.<p></div>';
}
```
Some other possibilities for displaying an error message include:
* If your site uses JavaScript which can display "flash" or "modal" messages (or you add such abilities on your own), add to it the logic to display messages on page-load when a specific variable is set, then add a `wp_enqueue_script` hook with a `$priority` larger than that which enqueues that JavaScript, and use `wp_localize_script()` to set that variable to include your error message.
* Use `wp_redirect()` to send the user to the URL of your choice (this method requires an additional page load).
* Set a PHP variable or invoke a method which will inform your theme/plugin about the error such that it may display it where appropriate.
* Set the `s` query variable to `''` instead of `' '` and use `page_id` in place of `post__in` in order to return a page of your choosing.
* Use a [`loop_start` hook](https://developer.wordpress.org/reference/hooks/loop_start/) to inject a fake `WP_Post` object containing your error into the query results - this is most definitely an ugly hack and may not look right with your particular theme, but it has the potentially desirable side effect of suppressing the "No Results" message.
* Use a `template_include` filter hook to swap out the search template with a custom one in your theme or plugin which displays your error.
Without examining the theme in question, it's difficult to determine which route you should take. |
261,042 | <p>First, I want to clarify - <strong>this is not a CSS question.</strong> </p>
<p>I want to change the data that is showing of the widget, when its in closed / open mode inside the wp-admin, in a sidebar or a page builder. Here is an image to better explain.</p>
<p><a href="https://i.stack.imgur.com/bBXNY.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bBXNY.jpg" alt="enter image description here"></a></p>
<p>I want to be able to add something / remove from the title of the widget dynamically and use widget $instance to do so</p>
<p><strong>The desired result:</strong><br>
Add a small info label stating mobile / desktop / both - which is an option picked inside that specific widget</p>
<p>Ideas anyone?</p>
<p><em>UPDATE</em><br>
<strong>Since i see some intrest in a solution to this question:</strong><br>
@cjbj solution works beautifully but only in the sidebar and only partially:</p>
<pre><code>add_filter ('dynamic_sidebar_params','wpse261042_change_widget_title');
function wpse261042_change_widget_title ($params) {
$widget_id = $params[0]['widget_id'];
$widget_instance = strrchr ($widget_id, '-');
$wlen = strlen ($widget_id);
$ilen = strlen ($widget_instance);
$widget_name = substr ($widget_id,0,$wlen-$ilen);
$widget_instance = substr ($widget_instance,1);
// get the data
$widget_instances = get_option('widget_' . $widget_name);
$data = $widget_instances[$widget_instance];
$use_mobile = $data['use_mobile']; // option inside my widget
if($use_mobile == 'yes') {$string = 'desktop / mobile';} else {$string = 'desktop only';}
$params[0]['widget_name'] .= $string;
return $params;
}
</code></pre>
<p>However.. you cannot insert any html in that string (or at least i couldnt)</p>
<p>Would update if i find a working solution.</p>

| First, I want to clarify - **this is not a CSS question.**
I want to change the data that is showing of the widget, when its in closed / open mode inside the wp-admin, in a sidebar or a page builder. Here is an image to better explain.
[](https://i.stack.imgur.com/bBXNY.jpg)
I want to be able to add something / remove from the title of the widget dynamically and use widget $instance to do so
**The desired result:**
Add a small info label stating mobile / desktop / both - which is an option picked inside that specific widget
Ideas anyone?
*UPDATE*
**Since i see some intrest in a solution to this question:**
@cjbj solution works beautifully but only in the sidebar and only partially:
```
add_filter ('dynamic_sidebar_params','wpse261042_change_widget_title');
function wpse261042_change_widget_title ($params) {
$widget_id = $params[0]['widget_id'];
$widget_instance = strrchr ($widget_id, '-');
$wlen = strlen ($widget_id);
$ilen = strlen ($widget_instance);
$widget_name = substr ($widget_id,0,$wlen-$ilen);
$widget_instance = substr ($widget_instance,1);
// get the data
$widget_instances = get_option('widget_' . $widget_name);
$data = $widget_instances[$widget_instance];
$use_mobile = $data['use_mobile']; // option inside my widget
if($use_mobile == 'yes') {$string = 'desktop / mobile';} else {$string = 'desktop only';}
$params[0]['widget_name'] .= $string;
return $params;
}
```
However.. you cannot insert any html in that string (or at least i couldnt)
Would update if i find a working solution. | Background:
-----------
The reason why filtering with `dynamic_sidebar_params` doesn't work with `HTML` is because WordPress strips `HTML` from Widget Heading in [`wp_widget_control()`](https://github.com/WordPress/WordPress/blob/4.7/wp-admin/includes/widgets.php#L216) function like this:
```
$widget_title = esc_html( strip_tags( $sidebar_args['widget_name'] ) );
```
WordPress also strips `HTML` in default JavaScript in [`wp-admin/js/widgets.js`](https://github.com/WordPress/WordPress/blob/4.7/wp-admin/js/widgets.js#L485)
So without a customised solution, there is no default filter or option either with PHP or with JavaScript to achieve what you want.
Custom PHP Solution:
--------------------
A custom PHP solution is possible that'll only work in `wp-admin -> Appearance -> Widgets`, but not in `Customizer -> Widgets`.
WordPress adds [`wp_widget_control()` function](https://github.com/WordPress/WordPress/blob/4.7/wp-admin/includes/widgets.php#L169-L272) (that generates Widget Control UI) with `dynamic_sidebar_params` hook, so it's possible to override it using this filter hook. However, in customizer, WordPress calls [`wp_widget_control()` function](https://github.com/WordPress/WordPress/blob/4.7/wp-admin/includes/widgets.php#L169-L272) directly, so this solution will not work for the customizer.
The solution works like the following (add this code in a custom plugin):
```
add_filter( 'dynamic_sidebar_params', 'wpse261042_list_widget_controls_dynamic_sidebar', 20 );
function wpse261042_list_widget_controls_dynamic_sidebar( $params ) {
global $wp_registered_widgets;
// we only want this in wp-admin (may need different check to enable page builder)
if( is_admin() ) {
if ( is_array( $params ) && is_array( $params[0] ) && $params[0]['id'] !== 'wp_inactive_widgets' ) {
$widget_id = $params[0]['widget_id'];
if ( $wp_registered_widgets[$widget_id]['callback'] === 'wp_widget_control' ) {
// here we are replacing wp_widget_control() function
// with our custom wpse261042_widget_control() function
$wp_registered_widgets[$widget_id]['callback'] = 'wpse261042_widget_control';
}
}
}
return $params;
}
function wpse261042_widget_control( $sidebar_args ) {
// here copy everything from the core wp_widget_control() function
// and change only the part related to heading as you need
}
```
As I said before, this solution doesn't work for the customizer and more likely to require future updates as we are overriding a core function.
Custom JavaScript Solution (Recommended):
=========================================
Fortunately, it's possible to customize this behaviour with JavaScript. WordPress updates Widget Control Heading with JavaScript anyway. To do that WordPress keeps a placeholder `in-widget-title` CSS class and updates it with the widget `title` field value from JavaScript CODE. We can manipulate this to achieve our goal.
### Related Core JS files:
First you need to know that WordPress loads [`wp-admin/js/customize-widgets.js`](https://github.com/WordPress/WordPress/blob/4.7/wp-admin/js/customize-widgets.js) file (with `customize-widgets` handle) in `wp-admin -> Customize -> Widgets` (customizer) and [`wp-admin/js/widgets.js`](https://github.com/WordPress/WordPress/blob/4.7/wp-admin/js/widgets.js) file (with `admin-widgets` handle) in `wp-admin -> Appearance -> Widgets` to manipulate Widget Control UI. These two files do similar operations for Widget UI markups and Widget Heading UI manipulation, but a lot of different things as well. So we need to consider that for our JavaScript based solution.
### Considerations for Customizer:
Customizer doesn't load Widget UI markup immediately after page load, instead, it loads with JavaScript when the corresponding `Widgets -> Sidebar` panel is open. So we need to manipulate the Widget UI after WordPress loads it. For example, since customizer CODE is event based, I've used the following line of CODE to set the event handler at the correct moment:
```
section.expanded.bind( onExpanded );
```
Also, customizer used AJAX to load changes immediately, that's why I've used the following line to tap into the data change:
```
control.setting.bind( updateTitle );
```
Also, I needed to tap into `widget-added` event with the following line of CODE:
```
$( document ).on( 'widget-added', add_widget );
```
### Common for Customizer & `wp-admin -> Appearance -> Widgets`:
Both the above mentioned JavaScript files trigger `widget-updated` event when an widget is updated. Although customizer does it immediately with AJAX, while traditional `Widget` admin does it after you Click the `Save` button. I've used the following line of CODE for this:
```
$( document ).on( 'widget-updated', modify_widget );
```
### Considerations for `wp-admin -> Appearance -> Widgets`:
Contrary to the customizer, traditional `Widgets` admin loads the Widget Control UI with PHP, so I've traversed the UI HTML to make the initial changes like this:
```
$( '#widgets-right div.widgets-sortables div.widget' ).each( function() { // code } );
```

### Plugin Usage:
>
> ***Note:*** With the above sample Plugin CODE as it is, if you set the `title` of a Widget to `yes`, then it'll show *(mobile/desktop)* within the Widget Control UI heading, all the other Widget's will have *(desktop only)* in the Heading. In the customizer the change will be immediate, in `wp-admin -> widgets` the change will show after you `save` the changes. Of course you can change this behaviour by modifying the CODE (in JavaScript) to do the heading change for a different `field_name` or to only show that specific heading to some widgets and not to all of them.
>
>
>
For example, say you have a field named `use_mobile`, and you want to set the heading to *(mobile/desktop)* when it's set to `yes`. Then set the `compare` variable to something like:
```
var compare = {
field: 'use_mobile',
value: 'yes',
heading: ' <i>(mobile/desktop)</i> ',
alt_heading: ' <i>(desktop only)</i> ',
heading_selector: '.in-widget-title'
};
```
Also, if you want to change the entire heading (instead of just `.in-widget-title`), then you may change the `heading_selector` setting along with the correct markup for `heading` & `alt_heading` to do so. The possibilities are endless, but make sure WordPress core CODE doesn't produce any error if you want to be too much creative with the resulting markup.
Page builder integration:
-------------------------
Whether or not either of these solutions will work for a page builder will depend on that page builder implementation. If it uses WordPress supplied methods to load Widget Control UI then it should work without any modification, otherwise similar (but modified) implication may be possible for page builders as well. |
261,043 | <p>I am using <a href="https://en-ca.wordpress.org/plugins/custom-list-table-example/" rel="nofollow noreferrer">the Custom List Table Example plugin</a> as a basis to create my own custom list table. Everything is great, except one thorny point.</p>
<p>When I am processing bulk actions via the <code>process_bulk_action()</code> method, I would like to redirect using <code>wp_redirect()</code>. Here is an example:</p>
<pre><code>function process_bulk_action() {
// Some security check code here

</code></pre>
<p>Please note, in the call <code>wp_redirect("http://url/path.php?update=1&message=some_message")</code>, I am trying to redirect to the same page that displays the list table in order to reload it with the result of the trash process.

<p>The problem is, I get an error message <code>Cannot modify header information - headers already sent by <file path></code>.</p>
<p>I understand what the message means, and the reasons behind it (the page is already loaded and cannot be redirected).

| I am using [the Custom List Table Example plugin](https://en-ca.wordpress.org/plugins/custom-list-table-example/) as a basis to create my own custom list table. Everything is great, except one thorny point.
When I am processing bulk actions via the `process_bulk_action()` method, I would like to redirect using `wp_redirect()`. Here is an example:
```
function process_bulk_action() {
// Some security check code here
// Get the bulk action
$action = $this->current_action();

wp_redirect("http://url/path.php?update=1&message=some_message");
exit;
}
}
```
Please note, in the call `wp_redirect("http://url/path.php?update=1&message=some_message")`, I am trying to redirect to the same page that displays the list table in order to reload it with the result of the trash process. Also note that there is a `message` in the path that allows me to display a notification to the user regarding the result of the bulk action.
The problem is, I get an error message `Cannot modify header information - headers already sent by <file path>`.
I understand what the message means, and the reasons behind it (the page is already loaded and cannot be redirected). However, how do I redirect then if I would like to do that after I process the bulk action? If redirect is not the correct solution, what other options do I have that allow me to re-load the custom `wp_list_table` again so that the listed records reflect items being deleted (i.e., less published items, and more items in trash)?
Thanks. | Understand hierarchy, You don't need to redirect as form are posting values on same page.
```
function process_bulk_action() {
// Some security check code here
// Get the bulk action
$action = $this->current_action();
if ($action == 'bulk_trash') {
// Code for the "delete process"
$delete_ids = esc_sql($_POST['bulk-delete']);
//loop over the array of record ids
foreach($delete_ids as $id) {
self::delete_item($id);
}
// show admin notice
echo '<div class="notice notice-success is-dismissible"><p>Bulk Deleted..</p></div>';
}
}
```
another method is prepare\_items
```
public function prepare_items() {
// first check for action
$this->process_bulk_action();
// then code to render your view.

[](https://i.stack.imgur.com/E6pJz.png)
just for reference, this is what my navbar looks like.
**CSS**
```
.menu-item-346 a {

}
.menu-item-346 a:hover, .menu-item-346 a:active {
color:var(--blue);
background:var(--white);
}
``` | Instead of writing custom styles like `.menu-item-346` where you are hardcoding some styles...
why not just add a **custom css class** with the editor under `Appearance -> Menus`.
Wordpress has this build in.
Under `Appearance -> Menus` you need to open the `Screen Options` and tick the box `CSS Classes`.
After this you can now add one or multiple classes to every single menu-item.
You than could just write some custom CSS rules for these classes.
This way, your customer could just add these classes by himself. (or not) |

| I am trying to change the logo one specific page of this wordpress site. <http://staging-domesticbliss.transitiongraphics.co.uk/db-home-help/>
Currently I know I am targeting the right page and element as I can hide the logo using:
```
.page-id-6935 .w-logo-img > img {
display:none;
}
```
But how do I now show the logo located at <http://staging-domesticbliss.transitiongraphics.co.uk/wp-content/uploads/2017/03/db-homehelp-black-xl.png>
Thanks in advance | Rather than using the tag in html, set the logo using the CSS background property. Use background-image:url(<http://staging-domesticbliss.transitiongraphics.co.uk/wp-content/uploads/2017/03/db-homehelp-black-xl.png>); instead. |
261,135 | <p>I would like to add a new menu item in the admin bar. So far, I have done the following:</p>
<pre><code>function add_book_menu_item ($wp_admin_bar) {
$args = array (
'id' => 'book',
'title' => 'Book',
'href' => 'http://example.com/',
'parent' => 'new-content'
);
$wp_admin_bar->add_node( $args );
}
add_action('admin_bar_menu', 'add_book_menu_item');
</code></pre>
<p>This is creating the <code>Book</code> menu item underneath the <code>+ New</code> menu (in the admin toolbar). However, the <code>Book</code> item comes in first (it is before the <code>Post</code> menu item). I would like it to appear between the <code>Media</code> and <code>Page</code> items. </p>
<p>The following image shows what I would like to do.</p>
<p><a href="https://i.stack.imgur.com/xTEut.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xTEut.png" alt="enter image description here"></a></p>
<p>How do I do that?</p>
<p>Thanks.</p>

``` | In your foreach loop just do a quick `print_r($category)` to see all available options.
Than you will see that you can use `$category->term_id` to get the `ID` of the term/category, instead of `$category->slug`.
So for example, by using your code from above:
```
$categories = get_categories();
$cats = array();
$i = 0;
foreach( $categories as $category ) {
// uncomment to see all $category data
#print_r($category);
if( $i == 0 ){
$default = $category->term_id;

``` | `echo` is a PHP language construct which pushes values to the output buffer. It does not have a return value, so concatenating it with a string would cause everything after the `echo` to immediately be sent to the output buffer, and everything prior to `echo` to compose the concatenated string. This is such a misuse of `echo` that PHP itself doesn't actually allow it - if you had WordPress debugging enabled you would see an error similar to
>

This error is what is causing your white screen - when not in debug mode, WordPress suppresses error output to avoid exposing potentially sensitive information to end-users.
You shouldn't use `echo` in shortcode logic, as internally WordPress does more processing with a shortcode's return value. So using `echo` in a shortcode has a good chance to mess up your final markup.
The inclusion of the `echo` before the `edd_get_cart_total()` does not result in currency formatting. I've dug through [the plugin in question's source code](https://github.com/easydigitaldownloads/easy-digital-downloads/blob/master/includes/cart/class-edd-cart.php#L1150) just to be sure. Rather, it's more likely that some function is hooked to the `edd_get_cart_total` filter to format the output in templates (thus formatting the total when you used it in your `header.php` template), however within the context of a shortcode that filter is not attached.
Conveniently, the plugin provides the `ebb_cart_total()` function which will always produce a currency-formatted total string. The first argument to the function is `$echo` which is true by default, and will cause the function to display the total instead of returning it - which, as detailed earlier, is not something you want to do in a shortcode - so set this argument to `false` to have the function return a string which you may concatenate with the rest of your shortcode markup.
All together:
```
function eddminicartfunc() {
return
'<div class="mobilemenucart">
<i class="fa fa-shopping-cart"></i>
<span class="header-cart-total"> ' . edd_cart_total( false ) . ' </span>

}

261,177 | <p>Following the <a href="https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/" rel="nofollow noreferrer">Wordpress documentation about the Rest Api</a>, i can manage to make an ajax POST working, but only when logged in to Wordpress. Here are the basic files shown in the documentation:</p>
<h3>functions.php</h3>
<pre><code>wp_localize_script( 'wp-api', 'wpApiSettings', array(
'root' => esc_url_raw( rest_url() ),
'nonce' => wp_create_nonce( 'wp_rest' )
) );
</code></pre>
<h3>app.js</h3>
<pre><code>$.ajax( {
url: wpApiSettings.root + 'wp/v2/posts/1',
method: 'POST',
beforeSend: function ( xhr ) {
xhr.setRequestHeader( 'X-WP-Nonce', wpApiSettings.nonce );
},
data:{
'title' : 'Hello Moon'
}
} ).done( function ( response ) {
console.log( response );
} );
</code></pre>
<p>I'm showing this example as it is presented as an easy one, but is <strong>not working</strong> when not logged in. It is always giving me a 401 Unauthorized response / “rest_cannot_create”...</p>
<p>Any tip ?</p>

| Following the [Wordpress documentation about the Rest Api](https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/), i can manage to make an ajax POST working, but only when logged in to Wordpress. Here are the basic files shown in the documentation:
### functions.php
```
wp_localize_script( 'wp-api', 'wpApiSettings', array(
'root' => esc_url_raw( rest_url() ),
'nonce' => wp_create_nonce( 'wp_rest' )
) );
```
### app.js
```
$.ajax( {
url: wpApiSettings.root + 'wp/v2/posts/1',
method: 'POST',
beforeSend: function ( xhr ) {
xhr.setRequestHeader( 'X-WP-Nonce', wpApiSettings.nonce );
},
data:{
'title' : 'Hello Moon'
}
} ).done( function ( response ) {
console.log( response );
} );
```
I'm showing this example as it is presented as an easy one, but is **not working** when not logged in. It is always giving me a 401 Unauthorized response / “rest\_cannot\_create”...
Any tip ?
Thank you ! | Here are three possible approaches:
1. A normal WP installation already has [custom fields](https://codex.wordpress.org/Custom_Fields) which you can add to your post. So you could use those to add the original author's name to. The only problem is that general themes usually do not display `the_meta`, because they do not know what to expect. In your case you would want to replace `the_author` in your theme with `the_meta` (don't mess with the original theme files, use a child theme!)
2. Easier, but a bit hacky: add the original authors to the user list. They don't need to know they have an account, just provide bogus e-mail addresses and don't let WP send their password to them. Now you can simply assign them as authors and they will have their own author page as well.
3. The most thorough approach is [adding a meta box](https://codex.wordpress.org/Plugin_API/Action_Reference/add_meta_boxes) yourself (or use a [plugin like WCK](https://ido.wordpress.org/plugins-wp/wck-custom-fields-and-custom-post-types-creator/)). This gives you complete control on how to insert the information in your child theme. |

The code works perfectly but is showing this error. | The function you want is `get_userdata()`. Since you need to do this outside the loop, the process is a little less straight-forward.
The first thing you need to do is set up a variable called `$curauth` which is an object that you create by accessing the database by using the `$_GET[]` superglobal.
```
$curauth = ( isset( $_GET[ 'author_name' ] ) ) ? get_user_by( 'slug', $author_name ) : get_userdata( intval ($author ) );
```
This assigning of `$curauth` must be in your `author.php` file.
After that, we can then use the `get_userdata()` function and feed it the ID from `$curauth`.
```
$auth_data = get_userdata( $curauth->ID );
```
And from there your conditional becomes:
```
if ( in_array( 'subscriber', $auth_data->roles ) ) {
// No Follow Code
} else {
// Follow Code
}
```
My advice would be to make this all a function in your `functions.php` file:
```
function author_nofollow( $author ) {
$auth_id = $author->ID;
$auth_data = get_userdata( $auth_id );
if ( in_array( 'subscriber', $auth_data->roles ) ) {
echo 'noindex, nofollow';
} else {
echo 'index, follow';
}
}
```
Then you would just call it like this:
```
<meta name="robots" content="<?php author_nofollow( $curauth ); ?>">
