   I have a custom taxonomy called 'test', and I want to filter the main loop to show only posts that are tagged with the term 'test_term'.

   I tried using the 'pre_get_posts' and the 'request' filters, and it doesn't seem to be working:

   //in functions.php
   add_action( 'pre_get_posts', 'test_pre_get_posts' );
   function test_pre_get_posts( $query ) {
   	$query->set('taxonomy','test');
   	$query->set('term','test_term');
   	return $query;
   }
   
   // and for the loop-index.php file in the theme:
   <?php  while ( have_posts() ) : the_post(); ?>
   ...
   <?php endwhile; ?>

   In query.php:1432 I printed out the value of $qv, and it does not seem to contain the changes I made in the pre_get_posts hook. The second conditional on line 1436 returns false as a result:

   isset($qv[$t->query_var])

   Thanks for the help,
   Dave Morris

   It seems that if I add this line:

   $wp_query->is_tax = true;

   And wrap it in an is_home() conditional statment, then it seems to work as I was expecting it to.

   Is this correct? Will it cause any other issues with other loops on the page?

   Thanks,
   Dave

   try

   query_posts('post_type=movie&NAMEOFTAXONOMY=CATEGORYNAMEOFTAXONOMY');

   ex.:

   query_posts('post_type=movie&genre=drama');

   That does work, but I want to hook this functionality in a plugin and have my theme handle the loop without any knowledge of the plugin. Does that make sense?
