I created a hierarchical custom post type called "films." It is hierarchical so it can have children elements.

I am using a conditional statement in my single-films.php to show different content for the parent page from the children pages like so:

<?php if( $post->post_parent != 0 ) {
    echo "Press Page";
} else {
    echo "Film Page";
} ?>

In the condition that the page is a child, I want to use a custom wordpress loop, that loops through it's parents content. I am guessing I will need to use a loop similar to this (for the children):

<?php $posts = query_posts('&post_parent=0'); ?>
<?php while(have_posts()) : the_post(); ?>

wordpress content

<?php endwhile; ?>

This isn't working correctly. I need it to pull any content I wish (custom field, title, featured image, etc) from it's parent. Any idea how I can modify this loop to pull content from it's parent?

Are you trying to loop through ONLY the parent, or are you trying to loop through the parent and the child? – mor7ifer Mar 18 '12 at 17:32
    
only the parent – JCHASE11 Mar 18 '12 at 17:52
    
Avoid query_posts, it should never be used, it will only cause you pain, headaches, nausea, and horrible migraine induced vomitting – Tom J Nowell Sep 30 '12 at 3:07

Use the following to change the query from querying the current page to querying the parent of the current page:

query_posts( 'p='.$post->post_parent  );

That will change the $wp_query object to hold only the parent of the current post.

Note: this is untested.

update

You can also do it with a custom WP_Query as so:

$args = array(
    'p' => $post->post_parent
);
$parent = new WP_Query( $args );

while( $parent->have_posts() ) : $parent->the_post();
    // loop stuff here
endwhile;

How does it fail? – mor7ifer Mar 18 '12 at 18:37
    
it has some strange permalink behavior and spits out an error: Fatal error: Cannot redeclare curpageurl() (previously declared – JCHASE11 Mar 18 '12 at 18:51
    
Try the updated method that I just posted, looks like query_posts() wants to be difficult. – mor7ifer Mar 18 '12 at 19:04
    
I tried it with no luck. Thanks for your efforts though, it seems that this isn't a common problem. What is the 'p'? – JCHASE11 Mar 18 '12 at 19:26

Use get post meta to extract the parents custom field:

for an image:

<?php

$image = wp_get_attachment_image_src(get_post_meta($post->post_parent, 'custom-field-key', true));
echo '<img src="' . $image[0] . '" />';
?>

For a text custom field:

<?php $variable = get_post_meta($post->post_parent, 'custom_field_name', true); ?>
