Hi.
I have a class that extended from Controller.
here is the class
the class name is Controller.php that located in protected/components/
class Controller extends CController
{
/**
* @var array the breadcrumbs of the current page. The value of this property will
* be assigned to {@link CBreadcrumbs::links}. Please refer to {@link CBreadcrumbs::links}
* for more details on how to specify this property.
*/
public $breadcrumbs=array();
public function init(){
parent::init();
}
public function checkAuth(){
if(Yii::app()->controller->action->id !== 'login'){
if(Yii::app()->user->isGuest){
$this->redirect(array('admin/login'));
}
}
}
}
the checkAuth() function is used to checking permission that allow only non-guest member to access the action in controller.
I have been using this way (manual way) to checking current user permission:
class SiteController extends Controller {
public function actionAdmin(){
$this->checkAuth();
...
}
public function actionAdd(){
$this->checkAuth();
...
}
public function actionEdit(){
$this->checkAuth();
...
}
}
whether there is another way that is more practical to put checkAuth function(). so I no longer need to put checkAuth function() every action controller?
thanks for advance 
thank you mr. Andy_s, fixed.
