Example 1: Modify Gallery Output

In this example, we’re going to modify the gallery output by using the get_post_galleries filter. This will help in updating the $galleries variable according to your website’s requirements.

    function weplugins_modify_get_post_galleries($galleries, $post) { 
        // Modify $galleries as needed
        return $galleries; 
    }
    add_filter( "get_post_galleries", "weplugins_modify_get_post_galleries", 10, 2 );
    

Example 2: Remove the Hook

Sometimes, you might need to remove a registered hook. Here’s how you can use remove_filter to remove the get_post_galleries filter.

    remove_filter( "get_post_galleries", "weplugins_modify_get_post_galleries", 10, 2 );
    

Always ensure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Conditional Gallery Modification

What if you want to modify galleries conditionally? This example demonstrates how you can add conditions to your gallery modifications.

    function weplugins_conditional_gallery_modification($galleries, $post) { 
        if ($post->post_type == 'custom_post_type') {
            // Modify galleries only for a specific post type
        }
        return $galleries; 
    }
    add_filter( "get_post_galleries", "weplugins_conditional_gallery_modification", 10, 2 );
