How to display parent pages up to a certain level

use breadcrumbs plugin like this https://www.adesblog.com/2009/04/16/wp-plugin-breadcrumbs/

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!!
