How to use disable_captions filter in WordPress

When you’re working with WordPress, hooks can make your life a lot easier. One such hook is the disable_captions filter. This filter prevents image captions from being appended to the image HTML when inserted into the editor. You can use this filter by registering it with add_filter. It’s a simple process that you can add to your theme’s functions.php file or, better yet, create a custom WordPress plugin to ensure your changes are safe during theme updates.

Now, let’s dive into how you can use the disable_captions filter with some live examples.

Live Example 1: Basic Usage

This example shows the simplest way to use the disable_captions filter.

add_filter( 'disable_captions', '__return_true' );

Live Example 2: Custom Function

In this example, we define a custom function weplugins_modify_disable_captions_defaults to manipulate the $bool parameter.

	function weplugins_modify_disable_captions_defaults($bool) { 
		// Update the $bool variable according to your website requirements and return this variable.
		// You can modify the $bool variable conditionally too if you want.
		return $bool; 
	}
	// add the filter
	add_filter( "disable_captions", "weplugins_modify_disable_captions_defaults", 10, 1 );
	

Live Example 3: Removing the Hook

Sometimes, you might need to remove a registered hook. Here’s how you can do it:

remove_filter( "disable_captions", "weplugins_modify_disable_captions_defaults", 10, 1 );

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
