What I want
I have several OG groups in which content can be published. I would like to display which OG groups a node has been published for when viewing the node page. Like in "This page is published for: Department A, Department B."
The code snipped below shows the data I have in the $node object in node.tpl.php. This data is generated by the OG module.
Extracted data from $node
...
[og_groups] => Array (
[993] => 993
[2078] => 2078
)
[og_groups_both] => Array (
[993] => Department A
[2078] => Department B
)
...
I know I could loop through the og_groups_both array in node.tpl.php and generate the output from there, but it feels like a quite dirty solution. The ideal solution would be to have a $og_groups variable in node.tpl.php, similiar to how $submitted is used in node.tpl.php (see below).
Example of how $submitted is used
<?php if ($submitted): ?>
<div class="submitted"><?php print $submitted; ?></div>
<?php endif; ?>
Should I use hook_load() in a custom module to insert the new variable $og_groups in $node or use template_preprocess_node(&$variables)? What options do I have and which solution would you recommend?
