Does not work with OG Reference fields

Does not work with Organic Groups 2.x reference fields.

This appears to be an OG problem. OG 2.x replaces the standard entity reference field system with its own custom og_membership table. It does not provide sufficient support for other modules to seamlessly integrate with this.

As a quick work around for a client, I did this in pfff.module at ll. 297 ff., for example:

 drupal_session_regenerate();

  if ( isset($fields_value['og_group_ref']) ) {
  	$tid=$fields_value['og_group_ref']['und'][0]['target_id'];
  	$result=db_query("INSERT INTO og_membership (type,etid,entity_type,gid,state,created,group_type,field_name,language) 
  				VALUES ('og_membership_type_default', $user->uid, 'user', 
  			$tid, '1', 1449887238, 'node', 'og_group_ref' , 'en') ");
  }

  user_save($user, $fields_value);

You'll likely want to replace the timestamp. Thanks.
