I Would use Custom Post Type and hierarchical Taxonomies with same Slug. Fortunately I found a good solution based on post_type_link filter here from TheDeadMedic.
mysite.com/products/category1/product-name1
mysite.com/products/category2/product-name2
mysite.com/products/category1/subcategory1/product-name1
mysite.com/products/category2/subcategory2/product-name2
...
The only problem is subcategory pages get 404.
So these URLs work:
mysite.com/products/category1/product-name1
mysite.com/products/category1/subcategory1/product-name1
But subcategory pages don’t work in hierarchical structure:
mysite.com/products/category1/subcategory1
mysite.com/products/category2/subcategory2
I can only access these subcategories without hierarchical structure. So these URLs work:
mysite.com/products/subcategory1
mysite.com/products/subcategory2
Have you got any idea how I could extend TheDeadMedic’s solution to hierarchical taxonomies too.
Add to the taxonomy registration:
