Programmatically assign new users to OG

Question

My site is sub-divided into organic groups.

Group administrators are allowed to create new users, but I need a way to auto-assign the new user to the same organic group the creating group administrator belongs to.

Can anyone tell me how I can accomplish this auto-assignment either programmatically or with a module?

Answer 1

You should write a custom module that implements hook_form_alter().

• Get the $form_id of the 'create new user' form that you want to alter.

  ( drupal_set_message($form_id); is an easy way to do this. )

• Add a custom submit handler to the 'create user' form that uses the respective details and the og_group() function to add the new user to the group.

  function MODULENAME_form_alter(&$form, &$form_state, $form_id) {
  
      if (isset($form_id) && $form_id == 'YOUROG_USERCREATION_FORMID') {
          $form['#submit'][] = 'MODULENAME_submit_handler';
      }
  
  }
  
  
  function MODULENAME_submit_handler($form, &$form_state) {
  
      $gid = $form_state['values']['groupID'];
      $uid = $form_state['values']['userID'];
  
      $account = user_load($uid);
      $values = array(
          'entity_type' => 'user',
          'entity' => $account,
          'state' => OG_STATE_ACTIVE,
         );
  
      og_group('node', $gid, $values);
  
      return $form;
  }
  

Just as a point of information, this code sample is geared towards OG 7.2.x.

If you're using OG 7.1.x, you drop the first argument in og_group, so it would be og_group($gid, $values);

Also, the possible $values you can use, and defaults, are as follows:

# taken directly from og.module

$values += array(
     'entity type' => 'user',
     'entity' => FALSE,
     'state' => OG_STATE_ACTIVE,
     'save' => TRUE,
     'force reload' => TRUE,
     'membership type' => OG_MEMBERSHIP_TYPE_DEFAULT,
     'membership fields' => array(),
     'created' => time(),
    );

Try the Rules module: http://drupal.org/project/rules

You could react on "User created" and assign the new user the group of the currently logged in user, which is the creator.
