I tried asking this question in the Wordpress Devlopment network without success, I tried showing only specific categories in the permalinks of the page.

Now permalink structure for all pages and posts (POST type)

example.com/the-post-title/

This works for all my post and page categories, I want all categories to look like this But I want this category "Downloads"

when I select it to display on these pages

example.com/downloads/the-post-title/

Can anyone help me with how to use php code or something else for this specific category.

I tried some plugins and searched on the web but didn't find anything relevant

add_action( 'init', static function () { add_rewrite_rule( ... ); } ); add_filter( 'post_link', static function ( $permalink, $post ) { // add test for post is in category return sprintf( '/downloads/%s', $post->post_name ); }, 10, 2 );
