Getting og membership type in template.tpl.php

Question

I want to obtain the organic groups role-id of a node/comment-author in node.tpl.php and comment.tpl.php.

I can't find an array that provides this information.

I want to add a class based on the authors membership type.

Dummycode:

<div id="header" class="<?php if ($author->rid == 7): print 'class-7'; endif; ?>">

How to do this for nodes and comments?

Note: for normal (non-organic-group) roles I use:

<?php if(in_array('administrator', $user->roles)): print 'admin-type'; endif; ?>

Which works ok, I want similar usage for organic group roles.

Found the anwser: This goes in node.tpl.php (tested on Drupal 7, Organic groups 7.x-2.3)

<?php if (og_context()) {
  $group = og_context();
  $userid = user_load($node->uid);
  $roles = og_get_user_roles('node', $group[gid], $uid = $userid->uid, $include = FALSE);
  }
?>

Then use it with something like:

<?php if(in_array('test member', $roles)): print '<span>Testuser</span>'; endif; ?>

For comments it's a little different:

<?php if (og_context()) {
  $group = og_context();
  $roles = og_get_user_roles('node', $group[gid], $uid = $comment->uid, $include = FALSE);
  }
?>

Works only on pages where groupcontext is available!
