Custom Taxonomy Taxonomies of Same Name point to first created URL

Question

I created a Custom Post type and in that custom post type have a hierarchical taxonomy (categories).

Here's an example of the categories I made:

Hats
 - Mens
 - Womens

Shoes
 - Mens
 - Womens

The problem is that when I go to the "Mens" sub-category of the "Shoes" Main category it goes to the Mens category of the "Hats" category, i'm guessing it's because the URL of the two is the same.

What is the best way around this problem?

Answer 1

This is a problem with wordpress that happened to me as well. If the titles of 2 terms (even if they are from different taxonomy), wordpress will not create another term in the database, instead link the previous term to taxonomy. If you look in your database, you'll find only 1 term with title "Mens" which will be a child of both Hats & Shoes. Also if you try to change the title/slug of one of those terms, wordpress will change the corresponding term under other taxonomy too. You can't separate them like this right now

Interestingly, if the terms you created were "Mens" & "mens", wordpress takes the slug of the 2nd to be "mens-2" & then it works as normal. I don't know if it's intentional but this thing was very frustrating the first time i found out.

Answer 2

I just hit this problem with regards to trying to automatically clear out terms for a custom taxonomy using TSQL, where terms from my main categories taxonomy with the same name would be deleted when I was only trying to delete terms associated with my custom taxonomy.

In regards to the issue of the two taxonomies having the same URL, have you tried applying a rewrite rule in your call to register_taxonomy()? For instance, I've got a main category "Baby", which lives at /baby, and a custom taxonomy for polls, which uses the very same term, "Baby", but lives at /polls/cat/baby.

It looks like this:

register_taxonomy(  
  'poll_category',  
  array('poll'),  
  array(  
    'public' => true,
    'hierarchical' => true,  
    'label' => 'Poll Category',  
    'query_var' => 'poll_category',  
    'rewrite' => array("slug" => "polls/cat", 'with_front' => FALSE), 
  )  
);
