Question

Hay guys, i have a general navigation which looks like this:

PAGE 1
    PAGE 1.1
        PAGE 1.1.1
        PAGE 1.1.2
    PAGE 1.2
        PAGE 1.2.1

I want to display a link on pages 1.1.1, 1.1.2 and 1.2.1. As you can see these are childrens’ children of the main navigation.

How would i do this in WordPress?

Use following code snippet inside the loop to achieve this objective:

<?php
if ($post->post_parent) {
   $parent = get_page($post->post_parent);
   $parentLink = get_permalink($parent->ID);

   if ($parent->post_parent) {
      $grandParent = get_page($parent->post_parent);
      $grandParentLink = get_permalink($grandParent->ID);
   }
}

// display the links to parent and grand parent pages now
echo $parentLink . ' | ' . $grandParentLink;
?>
