 * I have an issue.
 * I am have created page that will list all the posts of a certain type.
 * [http://betawww5.pyramidanalytics.com/resources](http://betawww5.pyramidanalytics.com/resources)
   
   I am trying to add filtering based on taxonomy
 * [http://betawww5.pyramidanalytics.com/resources?types=video](http://betawww5.pyramidanalytics.com/resources?types=video)
   
   This also works.
 * What is wierd is when i put a term that doesn’t exist
    [http://betawww5.pyramidanalytics.com/resources?types=vi](http://betawww5.pyramidanalytics.com/resources?types=vi)
 * The website redirects me to a 404 pages.
 * I have added a 2 checks to the page.
    1. Only include in the query the parameter
   if its set 2. Only include in the query the parameter if its a taxonomy/
 *     ```
       if(isset($_GET['types']) && is_term($_GET['types'] , 'types' ))
       {
       echo "ilanb".$_GET['types'];
       	$args = array(
       				'post_type' => 'resource_page',
       				'types' => $_GET['types']
       				);
       }else{
       				$args = array(
       				'post_type' => 'resource_page'
   
       				);
       				}
       ```

 * Have you made sure that the [query_var ‘types’ is set in a filter](http://codex.wordpress.org/Function_Reference/get_query_var#Custom_Query_Vars)?
 * You also might want to do this in your theme’s functions.php so that you can 
   use a the action [init](http://codex.wordpress.org/Plugin_API/Action_Reference/init).
   The ‘init’ action fires before the headers are sent. This way you can hijack 
   the page before it is redirected.
