Get parent of current page

Question

please help me: I need to get the parent of the current page, in other words: to get the parent of $direct_parent.Thanks!

<?php 
    global $post;
    $direct_parent = $post->post_parent;
    $parent = $direct_parent->post_parent;
wp_list_pages( array(
    'child_of' => $parent,
    'title_li'     => false,
    'depth' => 1
) );
?>

This code doesn't work(

Answer 1

Try using get_post_ancestors. Here is how you can apply this in your case:

<?php
    global $wp_query;
    $post = $wp_query->post;
    $ancestors = get_post_ancestors($post);
    if( empty($post->post_parent) ) {
        $parent = $post->ID;
    } else {
        $parent = end($ancestors);
    } 
    if(wp_list_pages("title_li=&child_of=$parent&echo=0" )) {                
        wp_list_pages("title_li=&child_of=$parent&depth=1" ); 
    } 
?>

You'll probably need to remove the depth parameters to show you're 3rd level pages.

Let me know if this helps!

Replace $parent in child_of argument of wp_list_pages by parent->ID. wp_list_pages needs the post id instead of post object.

<?php 
  global $post;
  $direct_parent = $post->post_parent;
  $parent = $direct_parent->post_parent;
  wp_list_pages( array(
   'child_of' => $parent,
   'title_li'     => false,
   'depth' => 1
 ) );
?>
