I am trying to display the ID of the group the user is currently viewing. I created a block, and added the following PHP code into it:

<?php
$group = og_context();
if ( !empty($group) ) {
   print "$group->nid";
}
?>

Problem is, when I run it, I get the following error:

Notice: Trying to get property of non-object

Any idea why this is happening, and how to fix it? Seems like it should be easy enough of a task.

  • <?php print arg(1); ?> if it is a node page... – Anil Sagar Mar 17 '14 at 8:53
  • Which version of Drupal are you using ? – Anil Sagar Mar 17 '14 at 8:55
  • I am using Drupal 7.26 – Lukas Pleva Mar 17 '14 at 8:55
  • @AnilSagar -- your suggestion worked. Can you please explain how this works? I am not super familiar with PHP. Thanks! – Lukas Pleva Mar 17 '14 at 8:57
  • Each content created using content types in Drupal is a node which will have nid and path node/nid . Groups also nodes.... you can read path arguments using arg function.. so arg(0) is "node" and arg(1) is nid of node...

In Drupal 7 the NID is the group ID so you could just output $node->nid.

  • But I need the group ID to be printed on all nodes associated with the group, not just on the group page itself. Apologies if I wasn't clear in my original ask. – Lukas Pleva Mar 17 '14 at 16:39
  • Is it possible for a content entity to be a member of more than one group on your site? – Rob Mar 17 '14 at 18:23

The basic problem is that og_context() doesn't return an object, or the group node - it returns an array of group information.

Basically, using your example code, you want $group['gid'], assuming that all of your organic groups are based off of nodes. If they aren't, you'll want to also look at $group['group_type']. See http://drupalcontrib.org/api/drupal/contributions!og!og_context!og_context.module/function/og_context/7 for more information about this function.
