<?php
function wp_check_post_hierarchy_for_loops( $post_parent, $post_ID ) {
// Nothing fancy here - bail
if ( !$post_parent )
return 0;
// New post can't cause a loop
if ( empty( $post_ID ) )
return $post_parent;
// Can't be its own parent
if ( $post_parent == $post_ID )
return 0;
// Now look for larger loops
if ( !$loop = wp_find_hierarchy_loop( 'wp_get_post_parent_id', $post_ID, $post_parent ) )
return $post_parent; // No loop
// Setting $post_parent to the given value causes a loop
if ( isset( $loop[$post_ID] ) )
return 0;
// There's a loop, but it doesn't contain $post_ID. Break the loop.
foreach ( array_keys( $loop ) as $loop_member )
wp_update_post( array( 'ID' => $loop_member, 'post_parent' => 0 ) );
return $post_parent;
