<?php
function wp_check_term_hierarchy_for_loops( $parent, $term_id, $taxonomy ) {
// Nothing fancy here - bail
if ( !$parent )
return 0;
// Can't be its own parent
if ( $parent == $term_id )
return 0;
// Now look for larger loops
if ( !$loop = wp_find_hierarchy_loop( 'wp_get_term_taxonomy_parent_id', $term_id, $parent, array( $taxonomy ) ) )
return $parent; // No loop
// Setting $parent to the given value causes a loop
if ( isset( $loop[$term_id] ) )
return 0;
// There's a loop, but it doesn't contain $term_id. Break the loop.
foreach ( array_keys( $loop ) as $loop_member )
wp_update_term( $loop_member, $taxonomy, array( 'parent' => 0 ) );
return $parent;
}
