Prevent Custom Card URL When Redirection Is Set

This snippet filters the wpex_card_url post meta to return empty if a redirection URL (wpex_post_link) exists. It ensures that custom card URLs are ignored on the front end when a redirect is configured. This way the redirection will take priority as the card URL.

/**
 * Filter the custom card URL to empty when a redirection is set.
 *
 * If a post has a 'wpex_post_link' defined, this snippet ensures that
 * 'wpex_card_url' returns an empty string on the front end, preventing
 * custom card links from conflicting with redirections.

        if ( $meta_key === 'wpex_card_url' && get_post_meta( $object_id, 'wpex_post_link', true ) ) {
            return $single ? '' : [ '' ];
