Guys
Please help, I am not able to submit my form variables and save it to database + there is no validation happening 
Registration Model
class registerForm extends CFormModel
{
public $username;
public $password;
public $email;
private $_identity;
/**
* Declares the validation rules.
* The rules state that username, password & email are required,
* and username & email needs to be unique.
*/
public function rules()
{
return array(
// username and password are required
array('username, password, email', 'required','message'=>'Required!'),
// make sure username and email are unique
array('username, email', 'unique'),
);
}
/**
* Declares attribute labels.
*/
public function attributeLabels()
{
return array(
'username'=>'Username',
'email'=>'Email Adress',
'Password'=>'Password',
);
}
}
CONTROLLER
public function actionRegister()
{
$model=new RegisterForm;
$newUser = new TblUser;
// if it is ajax validation request
// if(isset($_POST['ajax']) && $_POST['ajax']==='verticalForm')
// {
// echo CActiveForm::validate($model);
// Yii::app()->end();
// }
//echo $_POST['RegisterForm'];
// collect user input data
if(isset($_POST['RegisterForm']))
{
$model->attributes=$_POST['RegisterForm'];
if ($model->validate())
{
$newUser->Username = $model->username;
$newUser->Password = $model->password;
$newUser->Email = $model->email;
if($newUser->save())
{
$identity=new UserIdentity($newUser->Username,$model->Password);
$identity->authenticate();
Yii::app()->user->login($identity,0);
$this->redirect(Yii::app()->user->returnUrl);
}
}
}
$this->render('Register',array('model'=>$model));
// display the register form
}
