How to make a posttype show under a page hierarchy (example.com/page/posttype/entry)?

Question

I have a page, say streets, which is a static page and has the slug example.com/streets/, and I want to have many single streets under it. Let these streets be called streetdetails, so a single street detail would be example.com/streets/streetdetails/1.

When I create a posttype with Custom Post UI, I always get just top level slugs, such as example.com/streetdetails/1 and I cannot use the frontbase option either, as this is blog and will create false slugs.

How can I get that page -> posttype setup, that will put a posttype hierarchically under a page slug?

Answer 1

You need to alter your rewrite arguments in your register_post_type() call:

'rewrite' => array(
    'slug'       => 'streets/streetdetails',
    'with_front' => false,
);

Make sure to re-save permalinks in the admin after making the code change.
