Wordpress - Show parent category AND subcategory name in subcategory archive URL

Question

I'm having some trouble with Wordpress category/subcategory archive URLs.

For example, I want to be able to display this archive:
http://faroutmagazine.co.uk/wp/track-of-the-day while keeping its parent category in the URL, making it http://faroutmagazine.co.uk/wp/music/track-of-the-day

Previously, I was just getting a "This is embarrassing..." 404 message when accessing the /music/track-of-the-day URL (even though that's the one that was appearing in the View option under categories in the admin section of WP).

Now the View link in the admin area only shows me the /track-of-the-day URL, and this DOES display the category posts which is great, but I want it to include the parent category in the URL.

Is there anything I can do to the functions.php file or any plugins I can add to make this happen? Please bear in mind that there are multiple subcategory archives on this site, and they should all contain the parent category in the URL.

***UPDATE: I actually have just set everything up a different way now using Pages and showing category archives on pages as it's taking up too much time. Thanks for your answer though. People telling me to use %category%/%postname% as the permalink structure are incorrect - yes, this works for the POST urls but not for the archive category of the subcategory which is the problem I was actually looking for help with. If anyone can provide an answer, it would be appreciated, but I am using this workaround now as this was taking up way too much time trying to figure out.

Answer 1

You should set hierarchical value to true when you are defining your taxonomy.

'rewrite' => array('slug' => 'mySlug', 'hierarchical' => true),

Then if you have a subcategory the url will be shown like this: http://example.com/taxonomy/parentCategory/subCategory/

I found this sloution here:

Answer 2

This happens because you chose category and subcategory from the right options tick boxes when editing the entry. Choose only the subcategory box in every entry and it will show the nested URL.
