Display back to parent page link with get_post_ancestors

Adding the first snippet to the functions.php of your wordpress theme will display a link on sub pages back to the top level parent page. Place the second snippet within your theme in the location you want to display the link.

function wps_parent_post(){
  global $post;
  if ($post->post_parent){
	$parent = $ancestors[$root];
  } else {
	$parent = $post->ID;
  if($post->ID != $parent){
      echo '<a href="'.get_permalink($parent).'" class="parent-post">Back to parent page</a>';

  1. I used this on a site, but it is causing the top level pages to 404 unless I flush the rules regularly. Thoughts? Thanks

  2. Thanks for the snippet. Although it always points to the ‘root’ page, i.e. if I am on a grandchild page, it links to the grandparent instead of the parent.
