Custom Post Types Not Showing Up In query_posts Result

Question

This query works in some places, but not in others... right now it's not working on the home page. This query is in a file that is included into index.php of my theme.

The regular posts show, but no cutom post types. What's wrong with this query?

$args = array(
  'post_type' => array('post', 'video', 'slideshow', 'poll', 'quote'),
  'orderby' => 'date', 
  'order' => 'DESC'
); query_posts( $args ); 

Answer 1

Check that index.php is indeed being used, it's last resort kind of template when there is no more suitable one.

If you need this in multiple places across the site it might be better to run this in some hook, rather than in template file.
