[Plugin: Posts 2 Posts] Reciprocal relationship not being created

Hi Scribu

I’m having some issues with reciprocal links and I’m not sure if its a WordPress 3.2 thing or if I’ve done something wrong, or perhaps I’m just not understanding something. I’m using version 0.7 with WordPress 3.2.

In my functions file, I have the following:

function my_connection_types() {
	if ( !function_exists( 'p2p_register_connection_type' ) )
		return;
	p2p_register_connection_type( array(
		'from' => 'film',
		'to' => 'film',
		'reciprocal' => true
	) );
}
add_action( 'init', 'my_connection_types', 100 );

In my single-film.php file, I have:

$screenswith = "";
$connected = new WP_Query( array(
  'post_type' => 'film',
  'connected_to' => get_queried_object_id()
  ) );

if( $connected->have_posts() ) {
  $screenswith = '<div class="screenswith arrow_list"><h6>Screens with:</h6>';
$screenswith .= '<ul>';
while( $connected->have_posts() ) : $connected->the_post();
$screenswith .= '<li><a href="'.get_permalink().'" title="'.get_the_title().'" target="_blank">'.get_the_title().'</a></li>';
endwhile;
$screenswith .= '</ul>';
$screenswith .= '</div>';
}
wp_reset_postdata();
echo $screenswith;

The reciprocal relationship is being created in the admin backend, but on the front end, only one post shows the $screenswith data – the other post is “blank”. If I change the request from connected_to to connected_from, then they switch – the previously blank post now shows the connected post, and the other is then blank.

Perhaps I’ve just missed something in the wiki, but I thought reciprocal would create a from/to relationship in both directions on the front end as well?

Awesome, thanks so much for your swift response. Was that in the documentation (did I just miss it)?
