Support » Fixing WordPress » How to display parent pages up to a certain level

    Hello everybody.

    My problem seems relatively simple, yet I can’t seem to find a simple solution for it.

    I have a series of pages organized in 4 Levels, like so:
    Level 1
    – Level 2
    – – Level 3
    – – – Level 4

    What I would like to do, is add a sort of breadcrumb right before each page title which would display all parent pages (as links) of that current page in ascending order, but only up to Level 2 included.
    Here are some examples:
    @ If I’m on a Level 4 page, it would read:
    Level 2 Page title | Level 3 Page title | Level 4 page title
    @ If I’m on a Level 3 page, it would read:
    Level 2 Page title | Level 3 Page title
    @ If I’m on a Level 2 page, it would read:
    Level 2 Page title

    I tried using wp_list_pages but I couldn’t get it to work because it does not have a parent parameter. I also tried using get_pages('parent=0&hierarchical=0'), but I couldn’t get WP to display the pages obtained.

    Any help on this will be greatly appreciated!

  • Hi chinmoy,

    I was hoping to do it without plugins, since AFAIK it should pretty straight-forward. It’s just that, for some reason, I can’t seem to make it work.

    Hello again.
    I found a breadcrumb function on this site that comes really close to what I want. The code works for categories, pages, tags, etc., but since I only need this functionality for pages, I stripped down the rest and here’s what I got:

    function wordpress_breadcrumbs() {
      $delimiter = '|';
      $currentBefore = '<span class="current">';
      $currentAfter = '</span>';
      if ( !is_home() && !is_front_page() || is_paged() ) {
        echo '<div id="crumbs">';
        global $post;
    	if ( is_page() && !$post->post_parent ) {
    		echo $currentBefore;
    		the_title();
    		echo $currentAfter; }
    	elseif ( is_page() && $post->post_parent ) {
          $parent_id  = $post->post_parent;
          $breadcrumbs = array();
          while ($parent_id) {
            $page = get_page($parent_id);
            $breadcrumbs[] = '<a href="' . get_permalink($page->ID) . '">' . get_the_title($page->ID) . '</a>';
            $parent_id  = $page->post_parent;
          }
          $breadcrumbs = array_reverse($breadcrumbs);
          foreach ($breadcrumbs as $crumb) echo $crumb . ' ' . $delimiter . ' ';
          echo $currentBefore;
          the_title();
          echo $currentAfter;
        }
        echo '</div>';
      }
    }

    This is working well but it is not hiding page Level 1. Is there a way to add a filter or exclude parameter to this code so it does?

    Marventus, you’re an absolute star! Thank you so much for sharing this, been trying to get my head around this for AGES! Thank you!!

    For the not so fluent user, I would only add the following. The code Marventus pasted would go into the functions.php file, and where you want the code to appear, you would insert
    <?php wordpress_breadcrumbs(); ?>

    Thanks again!!
