    Hi all, I have a lot of 4th-level child pages and I’d like to display all of its parents as a tree e.g.

    Page 1
  Page 2 (i.e. parent of Page 3)
    Page 3
      Current page

    Try this:

    Lots of example uses at the bottom of the page.

    Perfect thank you so much. I used:

    <?php
//if the post has a parent
if($post->post_parent){
  //collect ancestor pages
  $relations = get_post_ancestors($post->ID);
  //get child pages
  $result = $wpdb->get_results( "SELECT ID FROM wp_posts WHERE post_parent = $post->ID AND post_type='page'" );
  if ($result){
    foreach($result as $pageID){
      array_push($relations, $pageID->ID);
    }
  }
  //add current post to pages
  array_push($relations, $post->ID);
  //get comma delimited list of children and parents and self
  $relations_string = implode(",",$relations);
  //use include to list only the collected pages.
  $sidelinks = wp_list_pages("title_li=&echo=0&include=".$relations_string);
}else{
  // display only main level and children
  $sidelinks = wp_list_pages("title_li=&echo=0&depth=1&child_of=".$post->ID);
}

if ($sidelinks) { ?>
  <h2><?php the_title(); ?></h2>
  <ul>
    <?php //links in <li> tags
    echo $sidelinks; ?>
  </ul>
<?php } ?>
