WordPress Rewrite

1. assuming u is a custom query var, you have to first add it to the array of recognized query vars:

   function wpa_query_vars( $query_vars ){
       $query_vars[] = 'u';
       return $query_vars;
   }
   add_filter('query_vars', 'wpa_query_vars');
   

   Then add an internal rewrite rule that accepts anything appended to vendors and passes that as the u query var:

   function wpa_rewrite(){
       add_rewrite_rule(
           'vendors/([^/]+)/?$',
           'index.php?pagename=vendors&u=$matches[1]',
           'top'
       );
   }
   add_action( 'init', 'wpa_rewrite' );
   

   Make sure to flush rewrite rules once for this rule to be added, you can also do this by just visiting the Settings > Permalinks admin page.

   Then in the template, you can access the value of u via get_query_var():

   $vendor = get_query_var( 'u' );
   

2. I believe this is what you are looking for:

   RewriteRule ^/site/vendors/([^/]*)$ /site/vendors/?u=$1 [L]
