function my_function_get_post_id_by_title( $title ) { // Get the post ID by its title $post_id = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_title = %s", $title )); return $post_id; } add_filter( 'getIdByName', 'my_function_get_post_id_by_title', 10, 1 );In the above code, we are retrieving the ID of a post by its title using the `getIdByName` hook in WordPress. This code can be added to the `functions.php` file of a WordPress theme. The package library for this hook is likely to be dependent on the CMS or framework being used, such as WordPress, Laravel, or CodeIgniter.
