Not sure if this can be done natively or if an add-on is out there.

I'm trying to figure out a way to limit entries with multiple parent categories to just one parent and it's children. The reason, I have nested product URL's:


Currently this works well for products with a single parent category.

Right now entries with multiple parent categories build "bad" URL's in the search results with this template code:

<a href="/products/{categories}{category_url_title}/{/categories}{url_title}">{title}</a>

Which works, if the entry has only one parent category assigned to it. If it has multiple, I get a nested URL with parent and child categories mixed together:


Any ideas on how I could limit the parent & child categories to just one parent tree? Thanks for the help!

I got this working correctly by using the Primary Category extension as Yuri recommended! I thought I would post my solution to help others in the future.

I created a conditional to check if the primary category is set and then built the URL based off the condition.

So if it returns true, the {primary_category_url_title} is placed outside the {categories} variable pair since it's going to be skipped inside the pair. Then I have another condition to skip all categories that don't have the same parent_id as the primary category set.

{if primary_category_id}
    <li><strong>{product_ci_model}</strong>: <a href="/products/{primary_category_url_title}/{categories}{if parent_id == primary_category_id}{category_url_title}/{/if}{/categories}{url_title}">{title}</a> - <em>Product<em></li>
    <li><strong>{product_ci_model}</strong>: <a href="/products/{categories}{category_url_title}/{/categories}{url_title}">{title}</a> - <em>Product<em></li>

It looks like Primary Category might help you

You can us the limit function with {categories} pair tag. This would still allow multiple categories, parent and children, but only display one for url purposes. like

<a href="/products/{categories limit="1"}{category_url_title}/{/categories}{url_title}">{title}</a>

Otherwise, take a look at GWCode's GW Categories. It allows an insane amount of category control.

  • I've tried this. If I limit=2 it will output the parent categories first, then the childs: http://domain.com/products/parent_cat/other_parent_cat/entry

  • I thought you said you were looking to get 1 category. The limit should be set to 1 not 2, otherwise, you're still dealing with multiple items. Not being related back. GW Categories will possibly give you better handling. Jan 23, 2013 at 19:19
  • Sorry for the confusion. I only wanted to build the url from one parent tree. The limit parament loops through parents first, then children. I was able to do it with Primary Category and conditionals
