I have a big problem. I have been banging my head on this all day long. It seems to be a stupid easy question. Possibly also with a stupid easy answer. But I can't seem to find it.

What I want is simple. I have a custom_post_type called "producten" and a taxonomy called "producten_categorie". Inside there I have got some couple hundred products that are all assigned to a "produten_categorie" term. I want to change the permalinks so they display the taxonomy term in the product permalink.

What I have now is as follows:

  • (producten archive)
  • (producten category archive)
  • (producten subcategory archive)
  • (single page for post in "producten")

What I want is the following:

  • (producten archive)
  • (producten category archive)
  • (producten subcategory archive)
  • (single page for post in main category)
  • (single page for post in sub category)

I can't get it to work. I first tried the "custom post type permalinks" plugin. Which did not work and gave me 404 errors. Even after flushing the permalinks more than a few times.

After that I tried manually changing the permalink by using "filter_post_type_link". But I just can't get it to work.

You can find my code for registering the post type on the taxonomy here ->

Hope someone can help me.

Custom post types, taxonomies, and permalinks

It will cover what you are trying to do for /category/subcategory/othersubcategory/posttitle.

Edit: I implemented this and fixed some issues with a double trailing slash. Look at this, it works How to fix a double slash in custom permalinks with hierarchical taxonomy's?

I know it's not a direct answer, but you could try the MagicFields plugin.

It makes working with custom post types and taxonomies a lot easier. I don't know if it is an overkill for your specific requirements though.

Try changing

'hierarchical' => false,


'hierarchical' => true,
