php yii unable to login using useridentity component -

here authentication controller

class authcontroller  extends controller {      public function actionlogin()     {         $model = new loginform;          $post = yii::app()->request->getpost('loginform');         // if form submitted         if($post) {             $identity = new useridentity($post['username'], $post['password']);              if($identity->authenticate()) {  // loop enters not id                 echo yii::app()->user->id;                 echo yii::app()->user->getid();             } else {                 echo 'failed';             }             //exit;         }         $this->render('login', array('model' => $model));        } } 

here useridentity.php

class useridentity extends cuseridentity {       private $_id;      public function authenticate()     {            $user = schlogins::model()->findbyattributes(array('username' => $this->username));         if(is_null($user)) {             $this->errorcode=self::error_username_invalid;         } else if($user->password != $this->password) {             $this->errorcode=self::error_password_invalid;         } else {              $this->_id = $user->id;              $this->errorcode=self::error_none;         }          return !$this->errorcode;     }       public function getid()     {         return $this->_id;     } } 

in above code having problem in getting user id (i.e) yii::app()->user->getid(); returns nothing , wrong did above code

you creating loginform instance $model never use login. if using standard loginform model interacts useridentity class. should this:

if($post) {     $model->attributes = $_post['loginform'];      if ($model->validate() && $model->login()) {  // loop enters not id         echo yii::app()->user->id;         echo yii::app()->user->getid();     } else {         echo 'failed';     }     //exit; } 

if @ login() function of loginform see calls yii::app()->user->login($this->_identity,$duration); sets yii::app()->user method being skipped.
