我通过posts 2 posts插件创建了post type event和用户之间的连接，还添加了注册连接的功能：

p2p_register_connection_type( array(
    \'name\' => \'multiple_authors\',
    \'from\' => \'event\',
    \'to\' => \'user\',
    \'to_query_vars\' => array( \'role\' => \'editor\' )
) );

作为wiki, 我需要添加此行以显示已连接用户的列表：

// To get a list of users connected to a certain post, you can write:

$users = get_users( array(
  \'connected_type\' => \'multiple_authors\',
  \'connected_items\' => $post
) );

但不要和我一起工作，你能建议我吗？

$users = get_users( array(
  \'connected_type\' => \'multiple_authors\',
  \'connected_items\' => $post
) );

foreach ( $users as $user ) {
    echo \'<p>\'.$user->name.\'</p>;
}
