 * Hi!
    Thanks for the great plug in, by the discussion I can see that it is something
   I really need for my site, but I have a problem using it on my network word press
   install (WP version: 3.1.2, PHP version: 5.2.14).
 * #1. I have two custom post types ‘artist’ and ‘event’, I created relation between
   them and meta boxes appeared in the admin UI. But connection disappears after
   I update artist or event.
    #2. I want to query related artists in the event admin
   part and add meta box where related artist’s title will become event’s custom
   field key and then I can have other information added there as custom field value.
   For now, when I copy paste the display code: `$connected = new WP_Query( array(‘
   post_type’ => ‘artist’, ‘connected_to’ => get_queried_object_id() ) );
 *  echo ‘<ul>’;
    while( $connected->have_posts() ) : $connected->the_post(); echo‘
   <li>’; the_title(); echo ‘</li>’; endwhile; echo ‘</ul>’;
 *  wp_reset_postdata();`
 * it shows ALL the artists. I assume it’s because of the issue #1, that the plugin
   doesn’t save the relations.
 * Do you have any ideas?

 * Note that `get_queried_object_id()` will only work when called from your theme’s
   single.php or page.php file.
 * In the admin, you will have to pass the exact post ID that you want. It’s up 
   to you to figure out how to get that ID. `$GLOBALS['post']->ID` might work.

 * And this happens using the default metabox in version 0.7?

 * Thanks for a quick answer!
    yes, plugin version is 0.7 network activated. adding
   connections through the metabox that appeared in the post edit/add admin after
   I registered a connection: [http://d.pr/Dwx1](http://d.pr/Dwx1) But after I hit“
   update” post or refresh page the event is gone from the list of added connections.
 * > In the admin, you will have to pass the exact post ID that you want. It’s up

 * Yes, I used `$_GET['post']` but I put it inside `get_queried_object_id()` and
   that was a mistake I guess.
 * Is this a correct usage:
 *  `$connected = new WP_Query( array(
    ‘post_type’ => ‘artist’, ‘connected_to’ 
   => $_GET[‘post’] ) );` Now the list is empty, and I think it’s correct as no 
   connection has been saved in the DB.
 * Thank you again for your help. I’m developing in a tight deadline so your help
   is greatly appreciated!

    I have a WP network thus all my blogs have prefix: wp_(blog
   id)_tablename. So here is the MySQL query I get when I look for connected artists:`
   SELECT SQL_CALC_FOUND_ROWS wp_9_posts.*, wp_9_p2p.* FROM wp_9_posts INNER JOIN
   wp_9_p2p WHERE 1=1 AND wp_9_posts.post_type` When I look in the DB, there’s only`
   wp_p2p` and `wp_p2pmeta` tables.

 * Ah, yes. You will need to install this plugin:
 * [http://wordpress.org/extend/plugins/proper-network-activation/](http://wordpress.org/extend/plugins/proper-network-activation/)
 * and then re-activate P2P.

 * Yes, as long as `$_GET['post']` contains the expected post id.
