[Plugin: Posts 2 Posts] Getting all metadata entries

  • Hi there,

    I have a post type “building”, that gets connected to let’s say 20 different users. As the users get connected to a certain “building” ID= 225 (via a front end form), they can choose their role by typing in a text, which is stored in the connection metadata field “role”. So I have 20 connections as below for that “building” with ID=225 with the following different entries for the metadata field “role”:

    architect (1 users), Architekt (1 user), designer (3 users), engineer (2 users), fan (8 users), manager (1 user), owner (1 user), visitor (3users)

    I know I can show a connection if I know the meta entries, but what happens if I do not know the meta entries?

    How would I go about getting all the connection meta entries for “role” that has been used for that particular connection type from that “building” with ID=225? Then I would like to show all users under the respective connection meta entry in “role”, so I can structure it as above.

    Not sure if that is clear….

    1. Get all connections.
    2. Group connections by their ‘role’ in a nested array.
    3. Display each group of connections.

    Thanks for your quick reply! Have not had time to try it out yet, but would I use the old p2p_split_posts function to achieve 2. ?
    Will try this tonight….

    1. Get all connections from current post viewed:

    $connected = new WP_Query( array(
  'connected_type' => 'building_to_user',
  'connected_items' => get_queried_object(),
  'nopaging' => true,
) );

    So all my connections from the “building” I am just viewing are in $connected.

    2. Group connections by field ‘role’ – Would I use the old p2p_split_posts function?

    /**
 * Split some posts based on a certain connection field.
 *
 * @param object|array A WP_Query instance, or a list of post objects
 * @param string $key p2pmeta key
 */
function p2p_split_posts( $posts, $key ) {
	if ( is_object( $posts ) )
		$posts = $posts->posts;

	$buckets = array();

	foreach ( $posts as $post ) {
		$value = p2p_get_meta( $post->p2p_id, $key, true );
		$buckets[ $value ][] = $post;
	}

	return $buckets;
}

$all_posts_by_role = p2p_split_posts( $connected, 'role' );

    3. Display each group:

    foreach ( $all_posts_by_role as $role ) {
	if ( !isset( $all_posts_by_role[$role] ) )
		continue;
	$posts_by_role = $all_posts_by_role[$role];
        echo $role;
        echo '<br>';
        foreach ( $posts_by_role as $post ) { ?>
               <div class="post-block">
				<li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li>
		</div>
	<?php }
} ?>

    Something like that. Just replace that last part:

    foreach ( $all_posts_by_role as $role ) {
	if ( !isset( $all_posts_by_role[$role] ) )
		continue;
	$posts_by_role = $all_posts_by_role[$role];

    with this:

    foreach ( $all_posts_by_role as $role => $posts_by_role ) {
