How to remove the sub-category from Woocommerce product URL

Question

In permalinks settings the 'Shop Base with Category' /shop/%product_cat%/ permalink setting puts all the hierarchical categories in the url, for example:

http:// mystore.com/shop/parent-category/child-category/product

I want to remove anything between parent-category and product so my urls look like:

http:// mystore.com/shop/parent-category/product

I am pretty sure that setting up urls like this does not cause problems, because I can manually type the shortened url into an address bar and it goes to the same place as the longer one.

Thanks.

It's actually quite simple. Use the woocommerce_product_post_type_link_parent_category_only filter:

add_filter( 'woocommerce_product_post_type_link_parent_category_only', '__return_true' );

Tried and tested working.

PS: The code would go into the theme functions file and __return_true() is a WordPress function.
