Is there a way to filter that output to only show the one location that was queried?

You need to store which location was queried, either by passing it as a URL parameter or saving it in a cookie.

Either way, you’ll need to write some custom PHP code.

No, and that’s intentional. You can, however, specify multiple connection types:

$posts = get_posts( array(
  'connection_type' => array( 'user_favorites', 'another_connection_type' ),
  'connected_items' => $some_user_id_or_object,
  'nopaging' => true,
  'suppress_filters' => false
) );

To be blunt, I currently have no interest in implementing this.

I already described the general idea in the previous post: http://ww.wp.xz.cn/support/topic/get_related-only-next-and-previous-post

I have no idea what you’re asking or why you would need what you’re asking.

Please post a more thorough explanation of the use case, and maybe some example code in a pastebin to go along with it.

Actually, get_adjacent_items() returns 3 post objects:

$items = p2p_type( 'posts_to_anime' )->get_adjacent_items( $episode_id );

echo get_permalink( $items['parent'] );

if ( $items['previous'] )
 echo 'previous: ' . get_permalink( $items['previous'] );

if ( $items['next'] )
 echo 'next: ' . get_permalink( $items['next'] );

Also, are you sure your connection type has 'sortable' => true?

The reason get_permalink() doesn’t work is because get_previous() and get_next() don’t return WP_Post objects; they return P2P_Item_Post objects.

This is fixed in the development version (1.5.2-alpha2).

As long as each group definition is stored as a row in the database somewhere, it should be possible. If groups are defined as a custom post type, it’s even easier.

If someone wants to take a stab at this, I’m willing to help them along.
