i an new in yii framework so didn't get a good tutorial for it, please suggest me how i insert the data into database by submitting a form

you can add this code in your controller:

public function actionRegister2()
{
     $model=new RegisterForm;
     if(isset($_POST['RegisterForm']))
     {
         $model->attributes = $_POST['RegisterForm'];
         if ($model->save()) {
            Yii::app()->user->setFlash('success', 'You have successfully added.');
            $this->redirect(array('index'));
        }
         // or if(!$model->save()){ print_r($model->getErrors())} 
    }
    $this->render('register2',array(
                    'model'=>$model,
           )); 
}
