How to use bulk_post_updated_messages filter in WordPress

bulk_post_updated_messages filter

By default, custom post types use the messages for the ‘post’ post type.

To use bulk_post_updated_messages filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_bulk_post_updated_messages_defaults which takes 2 parameters and we registered using add_filter. The first parameter bulk_post_updated_messages is name of the hook, The second parameter modify_bulk_post_updated_messages_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove bulk_post_updated_messages filter.

Parameters

Below are the 2 parameters are required to use this hook.

• $bulk_messages : (array[]) Arrays of messages, each keyed by the corresponding post type. Messages are keyed with ‘updated’, ‘locked’, ‘deleted’, ‘trashed’, and ‘untrashed’.
• $bulk_counts : (int[]) Array of item counts for each message, used to build internationalized strings.

Live Example

add_filter( 'bulk_post_updated_messages', 'my_bulk_post_updated_messages_filter', 10, 2 );
 function my_bulk_post_updated_messages_filter( $bulk_messages, $bulk_counts ) {
     $bulk_messages['my_cpt'] = array(
        'updated'   => _n( '%s my_cpt updated.', '%s my_cpts updated.', $bulk_counts['updated'] ),
        'locked'    => _n( '%s my_cpt not updated, somebody is editing it.', '%s my_cpts not updated, somebody is editing them.', $bulk_counts['locked'] ),
        'deleted'   => _n( '%s my_cpt permanently deleted.', '%s my_cpts permanently deleted.', $bulk_counts['deleted'] ),
        'trashed'   => _n( '%s my_cpt moved to the Trash.', '%s my_cpts moved to the Trash.', $bulk_counts['trashed'] ),
        'untrashed' => _n( '%s my_cpt restored from the Trash.', '%s my_cpts restored from the Trash.', $bulk_counts['untrashed'] ),

Below is an example how you can use this hook.

                        function modify_bulk_post_updated_messages_defaults($bulk_messages, $bulk_counts) { 
   
                            // Update the $bulk_messages variable according to your website requirements and return this variable. You can modify the $bulk_messages variable conditionally too if you want.

                            return $bulk_messages; 
                        }
                        // add the filter
                        add_filter( "bulk_post_updated_messages", "modify_bulk_post_updated_messages_defaults", 10, 2 );

To remove a hook callback, use the example below.

remove_filter( "bulk_post_updated_messages", "modify_bulk_post_updated_messages_defaults", 10, 2 );

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