 * I’m having the hardest time getting my plugin rewrite rules to work. Here’s my
   hook:
 *     ```
       public function __construct() {
          add_filter('generate_rewrite_rules', array($this, 'createRewriteRules'));
         ...
       }
       public function createRewriteRules($wp_rewrite) {
       	  $tag = 'shop';
   
           $newrules = array(
                               "{$tag}/(.+?)" => 'index.php?pagename=shopping&q=' . $wp_rewrite->preg_index(1),
                             ); 
   
           $wp_rewrite->rules =  $wp_rewrite->rules + $newrules;
           return $wp_rewrite;
       	}
       ```
   
 * When I print the wp_rewrite rules right before I return it above, I get:

 * You can see the last element is what I added.
 * If I visit index.php?pagename=shopping&q=category/1234 everything works fine.
   though if I visit /shop/category/1234 I get page not found.
 * Any advice would be much appreciated. Thanks!
