When you have Pages with children, the permalink structure works something like this:


All well and good. Trying to go to this URL:


doesn't work, which is good, and as expected - I only want the one URL for my child page.

However, I've set up a custom post type, and set it to be hierarchical, so as to behave like pages. It doesn't quite work the same way:


works as expected, but removing the parent page from the URL:


also displays the child page. It should 404, I would have thought.

I've used the following args to register_post_type:

$args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'show_ui' => true, 
    'show_in_menu' => true, 
    'query_var' => true,
    'rewrite' => array('slug'=>'custom-post-type','with_front'=>false),
    'capability_type' => 'post',
    'has_archive' => false, 
    'hierarchical' => true,
    'menu_position' => null,
    'supports' => array('title','editor','thumbnail','excerpt','revisions','page-attributes')

It's entirely possible I've misunderstood some of the options though. Can someone tell me if I'm doing something wrong, or if this is a bug or a feature?

I'm using 3.2.1, with no plugins, just my custom theme.

I have solved the answer to this problem by doing this:

echo get_permalink( $page->ID );

This gave me the right links to the pages.


The above could not happen. If you were to give 2 pages the same name (regardless of their parents being different) then WP would amend the slug of one of them.


Entering example.com/custom-post-type/child-page/ or example.com/custom-post-type/child-page-1/ would work as expected, but I believe that example.com/custom-post-type/parent-page-2/child-page/ would redirect you to example.com/custom-post-type/parent-page-1/child-page/ (although I am not 100% on that).

  • That's not the way it's working for me. I'm using 3.2.1 (should have mentioned that, will edit my main post to put it in), and can have example.com/custom/pagename, example.com/custom/parent1/pagename and example.com/custom/parent2/pagename - Wordpress happily creates them all automatically, without me editing the slug.

  • From the WP Codex for Pages → Add New - Avoid using the same title twice as that will cause problems. Maybe when adding/editing pages WP doesn't check for a unique slug, but it really should, else you will get all sorts of issues. The title can be the same, but the slug MUST be different - it is as unique as the ID.

  • I've amended my question, since this point wasn't what I was actually asking, just a way of illustrating the main problem. The duplicate name is easily fixed with a little reorganization, but I'm mostly interested in stopping example.com/custom/parent/child being also available at example.com/custom/child.

  • Id suggest having a look at the rewrite rules - $wp_rewrite is the global for that. It is possible to edit them, and probably this is just the default, if undesired, action.
