We need to create a new usergroup for the installation of our component, and the below code saves the data just as expected. However, retrieving the ID of the Usergroup for later use "isn't working".

Using JTable returns the ID, but won't fire any plugins - am I missing something obvious here in retrieving the ID of the record that the model just added?

$model = new UsersModelGroup(array('table_path' => $basePath.'/tables'));
$data = array('parent_id' => '2','title'=>'My Usergroup');
    $msg = 'Usergroup was not saved: '.$model->getError();
    $my_new_group_id = $model->get('id');    // Returns "null"

Try using the postSaveHook method which allows the controller to access model data after it has been saved.

public function postSaveHook($model, $validData)
    $item = $model->getItem();
    $my_new_group_id = $item->get('id');
  • Drat - foiled again by the getItem() method....glad I mentioned that I knew it was going to be obvious, lol.

    The trick is to call a local flower place and have them deliver it. Much cheaper that way ;) Commented Nov 2, 2014 at 0:15

Even though this is an old post. I wanted to post one of the solutions that helped me.

JLoader::import('group', JPATH_ADMINISTRATOR.'/components/com_users/models');
$groupModel = JModelLegacy::getInstance( 'Group', 'UsersModel' );
$groupId = $groupModel->getState('group.id');
