Writing Custom Rewrite Rules that Incorporate Category for Custom Post Types?

Question

I'm registering a Custom Post Type and in the rewrite array I am trying to do something like this:

'rewrite' => array('slug' => "explore/resources/".$CATEGORY, 'with_front' => false)

I want the rule to 'dynamically' get the post's category name somehow. I also tried using %category% there but it doesn't work either. I need the post's url to represent the entire path/route to it. Any ideas on how to achieve this?

UPDATE: Here is more clarification:

I have a custom post type of 'resources' and these post have several different categories like 'forms', 'mp3' etc. now this Resources area in the site is under another section (that is a page with custom loop for those custom posts) which is called Explore. What I want to achieve is:

domain.com/Explore/Resources/Resource-Category/Resource-Name

or

domian.com/explore/resources/forms/production-form-1

My current rewrite rule in register_post_type() is:

'rewrite' => array('slug' => "explore/resources", 'with_front' => false).

Thanks!

You could use my plugin:

http://wordpress.org/extend/plugins/custom-post-permalinks/

That will only work if it's a non-hierarchical post type.

If it's hierarchical, you're going to have to register the permastruct yourself. This is a huge ordeal which I don't have the time to write out at the moment. You can look at the code in my plugin above and try to work it out for yourself. Some pointers:

• In order to get the category into the URL, you're going to have to hook into the 'post_type_link'
• You'll also have to hook into 'parse_request' to make sure the post type is recognized.
