[Plugin: Posts 2 Posts] Problem with connecting 2 connection types

Hey…

first of all thanks to scribu for such an amazing plugin.

I am working with wordpress since years. But now I am stuck with a project from one of my clients.

The client wants to have a database for TV series.

So I created three post types: Series, Seasons and Episodes.

My first thought was to make a p2p_register_connection_type seasons <-> series and a p2p_register_connection_type episodes <-> seasons.

On the single-series.php the conditionals and variables should be ordered like this:

Example:

Title of Series: American Horror Story

American Horror Story tells us the story of Ben and Vivian Harmon an their daughter Violet…

<hr>

Seasons

Season 1
– Episode 1
– Episode 2
…

Season 2
– Episode 1
– Episode 2
…

My question is: What can I do to achieve this?

This is the code I have pasted to my single-series.php:

// Find connected posts
$connected = new WP_Query( array(
  'connected_type' => 'season-to-series',
  'connected_items' => get_queried_object(),
  'nopaging' => true,
) );

// Display connected posts
if ( $connected->have_posts() ) :
?>
<h3>Seasons</h3>
<ul>
<?php while ( $connected->have_posts() ) : $connected->the_post(); ?>
	<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endwhile; ?>
</ul>

<?php
// Prevent weirdness
wp_reset_postdata();

endif;

?>

// Find connected posts
$connected = new WP_Query( array(
  'connected_type' => 'episodes-to-seasons',
  'connected_items' => get_queried_object(),
  'nopaging' => true,
) );

// Display connected posts
if ( $connected->have_posts() ) :
?>
<h3>Episodes</h3>
<ul>
<?php while ( $connected->have_posts() ) : $connected->the_post(); ?>
	<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endwhile; ?>
</ul>

<?php
// Prevent weirdness
wp_reset_postdata();

endif;

?>

I am thankful for every hint. The project is done if I can solve this problem!

Thanks for reading this!
