   I have a loop that goes through all of the pages in my blog, but is there a way to retrieve the hierarchy of the current page? e.g. top-level, child, grandchild
   Thanks

   See Function_Reference/get_pages and the child_of argument

   I am using a child_of loop within my page loop to add the child pages to a drop down list. But within the child_of loop, I need to find what level it is at, or how many parents it has. This is my code:

   <?php foreach(get_pages('sort_column=menu_order&parent=0') as $page) { ?>
   <li class="page_item page-item-<?php echo $page -> ID; ?><?php if($_GET['page_id'] == $page -> ID) { echo ' current_page_item'; } ?>">
   <a href="<?php echo bloginfo('url') . "/?page_id=" . $page -> ID; ?>">
   <?php echo $page -> post_title; ?>
   </a>
   <?php if(get_pages('child_of='.$page->ID)) { ?>
   <ul class="<?php echo $page -> ID; ?> child">
   <?php foreach(get_pages('child_of='.$page->ID) as $child) { ?>
   <li class="page_item page-item-<?php echo $child -> ID; ?><?php if($_GET['page_id'] == $child -> ID) { echo ' current_page_item'; } ?>">
   <a href="<?php echo bloginfo('url') . "/?page_id=" . $child -> ID; ?>">
   <?php echo $child -> post_title; ?>
   </a>
   </li>
   <?php } ?>
   </ul>
   <?php } ?>
   </li>
   <?php } ?>

   within the second foreach loop, I need to find what hierarchy level the $child is at.

   I figured it out, I used an array $hierarchy and set:

   $hierarchy[$page -> ID] = 0;
   $hierarchy[$child -> ID] = $hierarchy[$child -> post_parent] + 1;

   this stored the hierarchy of each page for later use.
