   The function below returns all posts within a custom taxonomy called 'course'.

   I have no problem retrieving the custom meta-data as shown in the loop, however, I would to add a filter to posts returned by this function, similar to 'the_content' filter for individual posts.

   function get_menu_items_by_course($course) {
   	$args['course'] = $course;
   
   	$posts = new WP_Query( $args );
   
   	$menu_items;
   	foreach ($posts->posts as $post) {
   		$menu_items[]['item_name'] = $post->post_title;
   		$menu_items[]['description'] = $post->post_content;
   		$menu_items[]['menu_order'] = $post->menu_order;
   	}
   
   	//restore post global to current post in the main query
   	wp_reset_postdata();
   
   	return $menu_items;
   }

   Has anyone got any ideas on the best way to do this?

   Cheers,
   Mark

   Can you explain a bit more. What kind of filter? What do you want it to do?

   get_menu_items_by_course returns an array of posts and I would like to use an add_filter function on each of these posts before they are displayed on screen. If you are in the loop then you could use 'the_content' hook however I'm creating a custom loop so I cannot use this hook.

   try apply_filters
   

   $mycontent = apply_filters( 'the_content', $mycontent );
