   Hi, i'm currently developping a classified ads plugin.

   For this; i created a custom post type (ads) and 3 main taxonomies (ad_type,ad_category,ad_tag).

   Let's say we are looking for a red(ad_tag) car(ad_category) in the offers(ad_type).

   When you are browsing the ads and viewing the results, you can save the "search filters" used.

   It will save a user meta with the subscription (search filters) parameters; eg.

   umeta_id	user_id		meta_key	meta_value
      147		   1	   'ad_subscription'	array('ad_type'=>'offer','ad_category'=>'cars','ad_tag'=>'red');

   On the main ads page; a link for the user will be available; eg. /wordpress/ads/my-subscriptions/147.
   If I click on that link; it will load the subscription #147; fill the wp_query arguments with it;and the page will load the matching ads and display them in a custom way (because it's a subscription page).

   Here's my problem.
   Let's say we saved this subscription.

   But now, what if we are not on the subscription page but that we are searching for a red car in the ad offers...
   It is exactly the same arguments than in the subscription we saved.

   So I wrote a function to compare the searched arguments with every subscription's arguments; so I can now if the search made already have been saved in a subscription.
   That's one step.

   If the searched arguments ARE already saved in a subscription; I would like to REDIRECT to that subscription.
   And here i'm stuck. It makes an infinite loop.

   Could you see something that's wrong in this ? :
   

   add_action('pre_get_posts','ads_redirect_to_subscription');
   
   function ads_redirect_to_subscription(&$query) {
   
   	if ($query->query_vars['post_type']!='ad') return $query; //we are not searching for ads
   	if ($query->query_vars['ads_subscription']) return $query; //we ARE loading a subscription
   
   	$search = yclads_filter_query_args($query); //get ad search arguments
   
   	if(!$search) return $query; //no ad search arguments found
   
   		$subscription_id=self::args_are_already_subscription_id($search); //compare search arguments with subscriptions
   
   		if ($subscription_id!=$query->query_vars['ads_subscription']){
   			wp_redirect(yclads_get_subscription_link($subscription_id));
   			die();
   
   		}
   	}

   Thanks a lot !

   I finally found out.
   Don't think anyone will need this, but it can help :

   function redirect_to_subscription(&$query) {
   		global $wp_query;
   
   		//!!WE NEED TO USE WP_QUERY HERE
   
   		if ($wp_query->query_vars['post_type']!='yclad') return $query;
   		//if ($query->query_vars['yclads_subscription']) return $query;
   
   		//SUBSCRIPTION QUERY
   		$q_subscription_id=yclads_get_subscription_id_from_slug($wp_query->get('yclads_subscription'));
   
   		//SEARCHED ARGS
   		$search = yclads_filter_query_args($wp_query);
   		if(!$search) return $query;
   		$u_subscription_id=self::args_are_already_subscription_id($search);
   
   		if($q_subscription_id==$u_subscription_id) return $query;
   
   		$existing_subscription=$this->user_subscriptions[$u_subscription_id];
   
   		wp_redirect(yclads_get_subscription_link($existing_subscription['slug']));die();
   	}
