Custom WP Die Handler Function

This file contains a custom WordPress function that handles specific error messages by redirecting users to a designated page if they reach their download limit. The function checks the error message for a download limit notice and, if it matches, verifies if the redirect page exists and is published before redirecting the user. If the redirect page is not valid, a default error message is displayed.

<?php function cwpai_custom_wp_die_handler( $message, $title = '', $args = array() ) { // Define the page ID where users will be redirected $redirect_page_id = 2; // Check if the message is about the download limit if ( strpos( $message, 'Sorry, you have reached your download limit for this file' ) !== false ) { // Check if the redirect page exists and is published $redirect_page = get_post( $redirect_page_id ); if ( $redirect_page && $redirect_page->post_status == 'publish' ) { wp_redirect( get_permalink( $redirect_page_id ) ); exit; } else { // Redirect page is not valid, show a default error message echo 'The page you are trying to access is not available. Please contact support.'; exit; } } // Default behavior for other cases _default_wp_die_handler( $message, $title, $args ); } add_filter( 'wp_die_handler', function() { return 'cwpai_custom_wp_die_handler'; } );
