I am working on an invitation system using organic groups and I needed the ability to programatically add a user to a (closed) organic group when they register for a new account. I tried to use the og_subscribe_user function, but it tests if the group allows registrations. In my situation the groups are closed, so I had to resort to the og_save_subscription function:
<?php
function MYMODULE_user($op, &$edit, &$account, $category = NULL) {
switch ($op) {
case 'insert':
// in my example, I'm querying a database for this number:
$groupID = 'some number';
og_save_subscription($groupID, $account->uid, array('is_active' => 1));
break;
}
}
?>
