#51715 new defect (bug)

get_permalink: stdClass treated as WP_Post causes bad behavour

Normally get_permalink() expects post as int|WP_Post
But actually, we can call get_permalink() with a custom stdClass who has needed properties to work (retrieve posts with custom query), but the hooks used in the function get_permalink()

  • post_link_category
  • pre_post_link
  • post_link_category
  • post_link

expects WP_Post object as parameter not a stdClass


         * @param string $permalink
         * @param WP_Post $post
         * @param bool $leavename
        function custom_link( $permalink, $post, $leavename = false ) {
                my_first_function( $post );

                my_second_function( $post );

         * @param WP_Post $post
        function my_first_function( $post ) {
                if ( $post instanceof WP_Post ) {

         * @param WP_Post $post
        function my_second_function( WP_Post $post ) {
                //FATAL ERROR

        add_filter( 'post_link', 'custom_link', 10, 3 );

         * @var stdClass $my_custom_post
        get_permalink( $my_custom_post );
