   I have a hierarchical custom post type, and on each single view of a post of this type I want to display the full title, content, etc. from the children of this post. This is outside of the main Loop.

   However, the code below has very strange results; the post_content and the_ID are from the correct child-post, but the_title and the_permalink are from the parent post, like this:
   

   <h1><a href="parentpermalink.php">Parent Title</a></h1>
   <p>Parent Content</p>
   <p>Parent Meta</p>
   <h1><a href="parentpermalink.php" id="post-first-child">Parent Title</a></h1>
   <p>First Child Content</p>
   <h1><a href="parentpermalink.php" id="post-second-child">Parent Title</a></h1>
   <p>Second Child Content</p>

   Using get_children instead of get_posts has the same results:
   

   global $post;
   $parent = $post->ID;
   
   $children = get_posts('post_parent='.$parent.'&&post_type=cruise&&post_status=publish');
   foreach($children as $child) :
   setup_postdata($child);
   ?>
   <h2><a href="<?php the_permalink(); ?>" id="post-<?php the_ID(); ?>">
       		<?php the_title(); ?></a></h2>
    			<?php the_content();
     			endforeach; ?>

   Any help would be much appreciated.
   Thanks.

   Hi Ryansigg.

   I don't know if you found a solution for this or if it's too late now, but have you tried this:

   <?php wp_reset_query(); ?>
   <?php
   global $post;
   
   $loop = new WP_Query(array('post_type' => 'cruise', 'post_status' => 'publish'));
   while ( $loop->have_posts() ) : $loop->the_post(); ?>
   	<h2><a href="<?php the_permalink(); ?>" id="post-<?php the_ID(); ?>">
   	<?php the_title(); ?></a></h2>
    	<?php the_content();
   endforeach; ?>

   Thanks for that, Vayu. Would you know how to exclude children from a hierarchical post type loop?

   $loop = new WP_Query(array('post_type' => 'cruise', 'post_status' => 'publish'));

   I figure this would include the argument that I need. But I don't see anything under query_posts or WP_query that would allow for that.

   Hi Chadvonlind,

   your welcome. :-)

   This is one way I found that seems to work:

   <?php
   $args = array(
   	'post_type' => 'cruise',
   	'posts_per_page' => -1,
   	'post_status' => 'publish',
   	'order' => 'ASC',
   	'post_parent' => 0
   );
   $loop = new WP_Query( $args ); ?>

   All top parents have have a post_parent id of zero.

   Hope this works for ya! :-)

   That works great! Can I buy you a beer? Do you have a paypal account?
