   Hi all, I've been having some trouble getting the slug (post_name) of a page's parent for some time now. I've figured out how to tell if a page is a child of another and all that, but all I can seem to get from that parent is its ID:

   $post_obj = $wp_query->get_queried_object();
   $post_name = $post_obj->post_name;
   $parent_name = $post->post_parent;

   This just returns the ID of the parent page, and I really need to return the slug.

   I have this function that does it elsewhere, but I can't see to make it work for the parent:

   function the_slug() {
   	$post_data = get_post($post->ID, ARRAY_A);
   	$slug = $post_data['post_name'];
   	return $slug;
   }

   Say I have a main page called "Welcome" with the slug "welcome" and a sub-page under Welcome that is called "Hello" with the slug "hello." I need to be able to use the value "welcome" when I'm on the page "Hello"

   Any help someone could provide would be much appreciated.

   function the_parent_slug() {
     global $post;
     if($post->post_parent == 0) return '';
     $post_data = get_post($post->post_parent);
     return $post_data->post_name;
   }

   Hi caugb, thanks for this but I'm not sure how to get the output

   I put your code in the functions.php file and I thought I'd do something like

   echo $post_data

   to get the results, but I don't think that's it

   What should I be using to get the post parent's slug?

   Thanks

   Nick

   try either:

   <?php echo the_parent_slug(); ?>
   and add the function (from the reply by @caugb) into functions.php of your theme.

   or:

   <?php
   global $post;
   if($post->post_parent) { $post_data = get_post($post->post_parent);
   echo $post_data->post_name; }
   ?>
