Hello everyone,
I'm trying to display breadcrumbs for a page. I'm using get_post_ancestors() function, but it returns an empty array, even though there is definately a parent. Also, I've testing it with $post->ancestors which returns an array with page's parent ID ... but get_post_ancestors() still returns an empty array.
Does anyone know what might be a problem??
I'm using the following function in my functions.php This is simplified version of code I found in Codex http://codex.wordpress.org/Function_Reference/wp_list_pages#List_current_Page.2C_ancestors_of_current_page.2C_and_children_of_current_page
<?php
function breadcrumbs() {
global $post;
//if the post has a parent
if($post->post_parent){
//collect ancestor pages
$relations = get_post_ancestors($post->ID);
//add current post to pages
array_push($relations, $post->ID);
//get comma delimited list of children and parents and self
$relations_string = implode(",",$relations);
//use include to list only the collected pages.
$sidelinks = wp_list_pages("title_li=&echo=0&include=".$relations_string);
}
if ($sidelinks) { ?>
<div id="breadcrumbs">
<div class="page-title-inner">
<ul>
<?php
//links in <li> tags
echo $sidelinks; ?>
</ul>
</div>
</div>
<?php }
} ?>And then I call breadcrumbs() function from my theme templates:
<?php breadcrumbs(); ?>
Thanks,
Dasha
