Exclude subcategories from the url

7 comments

1. If you go to Settings->Permalinks you should be able to set the tag/category base URL rules which should solve this problem.

   Or, use some sort of plugin to do what you want. This one came up first on Google: http://wordpress.org/plugins/custom-permalinks/

2. try the following code :

   function remove_child_categories_from_permalinks( $category ) {
       while ( $category->parent ) {
           $category = get_term( $category->parent, 'category' );
       }
       return $category;
   }
   add_filter( 'post_link_category', 'remove_child_categories_from_permalinks' );
   

3. Yes you can! Just select the primary category of the post.

   I am sorry that this screenshot is german, but it is pretty self-explaining. Here we have a main group “Party” with a subgroup “Rezepte”. We can set the url to only “/party” by selecting that category as a new main.

   

   The screenshot is taken from WordPress 5.8

   Also make sure your permalink structure (Settings->Permalinks) is set to /%category%/%postname%!

4. You can rewrite you .htaccess if you are familiar with this.

   Add the below line and try it:

   RewriteRule ^category/(.+)$ http://www.site.com/$1 [R=301,L]
   

5. This should work fine. Add this to your end of functions.php file.

   examplesite.com/wp-content/theme/yourtheme/functions.php <<- right there.

   // Remove category base
   add_filter('category_link', 'no_category_parents',1000,2);
   function no_category_parents($catlink, $category_id) {
       $category = &get_category( $category_id );
       if ( is_wp_error( $category ) )
           return $category;
       $category_nicename = $category->slug;
   
       $catlink = trailingslashit(get_option( 'home' )) . user_trailingslashit( $category_nicename, 'category' );
       return $catlink;
   }
   
   // Add our custom category rewrite rules
   add_filter('category_rewrite_rules', 'no_category_parents_rewrite_rules');
   function no_category_parents_rewrite_rules($category_rewrite) {
       //print_r($category_rewrite); // For Debugging
   
       $category_rewrite=array();
       $categories=get_categories(array('hide_empty'=>false));
       foreach($categories as $category) {
           $category_nicename = $category->slug;
           $category_rewrite['('.$category_nicename.')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
           $category_rewrite['('.$category_nicename.')/page/?([0-9]{1,})/?$'] = 'index.php?category_name=$matches[1]&paged=$matches[2]';
           $category_rewrite['('.$category_nicename.')/?$'] = 'index.php?category_name=$matches[1]';
       }
       // Redirect support from Old Category Base
       global $wp_rewrite;
       $old_base = $wp_rewrite->get_category_permastruct();
       $old_base = str_replace( '%category%', '(.+)', $old_base );
       $old_base = trim($old_base, '/');
       $category_rewrite[$old_base.'$'] = 'index.php?category_redirect=$matches[1]';
   
       //print_r($category_rewrite); // For Debugging
       return $category_rewrite;
   }
   
   // Add 'category_redirect' query variable
   add_filter('query_vars', 'no_category_parents_query_vars');
   function no_category_parents_query_vars($public_query_vars) {
       $public_query_vars[] = 'category_redirect';
       return $public_query_vars;
   }
   // Redirect if 'category_redirect' is set
   add_filter('request', 'no_category_parents_request');
   function no_category_parents_request($query_vars) {
       //print_r($query_vars); // For Debugging
       if(isset($query_vars['category_redirect'])) {
           $catlink = trailingslashit(get_option( 'home' )) . user_trailingslashit( $query_vars['category_redirect'], 'category' );
           status_header(301);
           header("Location: $catlink");
           exit();
       }
       return $query_vars;
   }
   

6. If you’re using WP Category permalink plugin then disable it and use the following as your permalink custom structure

   /%category%/%postname%/

   That’s it

7. Just go to:

   www.example.com/wp-admin/options-permalink.php (Settings->Permalinks)
   

   and choose /%category%/%postname%/

   That should do it.!
