Get Parent Page link from Child Page

Got to be in The Loop.

<?php if ($post->post_parent != 0) {
wp_list_pages('title_li=&include='.$post->post_parent);
}
?>

Thanks for your reply MichaelH, that’s exactly the line I had, only wrapped in a conditional…

I just tried to put it in The Loop, and it still didn’t work.

There’s no restriction on wp_list_pages being in the loop, of course, since we know it usually lives in the sidebar, and $post->post_parent works even WITHOUT a loop, actually returning the correct ID number (I can echo it to make sure).

For some reason the wp_list_pages simply returns null when attempting to list the parent even if I manually type the ID number in the function args.

Something screwy is going on.

Cheers for the reply.

I got this to work without an issue. I am on WP 2.2. I wanted to have a menu with a submenu and when you are on the submenu page i wanted it to continue to show the submenu items … ie the current page and its peers … I also highlight the menu item and the submenu item that you are on.

It’s got a limitation in that every page has to be on the menu or submenu for it to work. I am sure though that there is an easy enough bit of logic that could be added to address this.

Here is what i have in my header.php

<div id="header">
  <ul id="nav">
    <?php
    $mainID = 3; /* set this to the parent of your menu items */
    wp_list_pages('child_of='.$mainID.'&sort_column=menu_order&depth=1&title_li=');
    ?>
  </ul>

  <div class="hr"><hr /></div>

  <ul id="nav">
    <?php
    /* get the parent ID */
    if ($post->post_parent != 0)
    {
      $parentID = $post->post_parent;
    }

    if ($parentID != $mainID)
    {
      /* we are not on a main menu page grab this page's siblings */
      /* this does assume that all pages are menu or submenu items */
      $submenuparentID = $parentID;
    }
    else
    {
      /* we are on a main menu page so grab this page's children */
      $submenuparentID = $post->ID;
    }

    wp_list_pages('child_of='.$submenuparentID.'&sort_column=menu_order&depth=1&title_li=');
    ?>
  </ul>
</div> <!-- #header -->
