I use parent category and child category.

If i publish a post from child category, the URL is: domain.be/category/subcategory/post-title

i need, if i select the both, the url with cat and subcat.

In Wordpress BO > setting > permalink:

Answer 1

First of all, When modifying the url permalink structure it is best practice to flush the rewrite rules using the Wordpress flush_rewrite_rules() function.

Remove rewrite rules and then recreate rewrite rules.

You're actually on the right track, indeed you need to use /%category%/%postname%/ in your custom permalink structure.

For the purpose of this example, let's declare two categories, a parent and a child, Fruits and Tomatoes .

Fruits
└── Tomatoes

Wordpress uses the hierarchical alphabetical order to choose which category will be used in the url permalink structure. By default Wordpress can't display more than 1 category per level.

Behaviour	Description
Possible	eg: domain.com/parent/child/grand-child/my-first-post/
NOT Possible	eg: domain.com/parent-1/parent-2/my-first-post/

If we want our url to be domain.com/fruits/my-first-post/ we need AT LEAST to select the fruits category.

If we want our url to be domain.com/fruits/tomatoes/my-first-post/ we need to select the tomatoes category ONLY .

On your end, you simply need to unselect yhe top level categories associated with your child category and you should be good to go.
