Yii form not validating - php

Question

This is my code in actionCheckout():
public function actionCheckout() {
$proInfo = Yii::app()->session['cart'];
if (Yii::app()->user->isGuest) {
$model = new Payment;
// Uncomment the following line if AJAX validation is needed
// $this->performAjaxValidation($model);
if (isset($_POST['Payment'])) {
$model->attributes = $_POST['Payment'];
$model->thoigian = date('Y-m-d H:i:s');
if ($model->save()) {
foreach ($proInfo as $key => $value) {
$order = new Order;
$order->id_sp = $key;
$order->soluong = $value;
$product = Product::model()->findByPK($key);
if (empty($product->khuyenmai)) {
$price = $product->gia_sp;
} else {
$price = ceil($product->gia_sp * (100 - $product->khuyenmai) / 100 / 1000) * 1000;
}
$order->thanhtien = $price * $value;
$order->id_payment = $model->id_hoadon;
$order->save();
}
unset(Yii::app()->session['cart']);
$this->redirect(Yii::app()->request->baseUrl . '/cart/success/' . $model->id_hoadon);
}
}
$this->render('checkout', array(
'cart' => $proInfo,
'model' => $model,
));
} else {
$model = new Payment;
$user = User::model()->findByPk(Yii::app()->user->id);
// Uncomment the following line if AJAX validation is needed
// $this->performAjaxValidation($model);
if (isset($_POST['Payment'])) {
$model->attributes = $_POST['Payment'];
$model->id_user = Yii::app()->user->id;
$model->hoten = $user->hoten;
$model->email = $user->email;
$model->dienthoai = $user->dienthoai;
$model->diachi = $user->dia_chi;
$model->thoigian = date('Y-m-d H:i:s');
$model->xuly = "Chưa xử lý";
if ($model->save()) {
foreach ($proInfo as $key => $value) {
$order = new Order;
$order->id_sp = $key;
$order->soluong = $value;
$product = Product::model()->findByPK($key);
if (empty($product->khuyenmai)) {
$price = $product->gia_sp;
} else {
$price = ceil($product->gia_sp * (100 - $product->khuyenmai) / 100 / 1000) * 1000;
}
$order->thanhtien = $price * $value;
$order->id_payment = $model->id_hoadon;
$order->save();
}
unset(Yii::app()->session['cart']);
$this->redirect(Yii::app()->request->baseUrl . '/cart/success/' . $model->id_hoadon);
}
}
$this->render('checkout', array(
'user' => $user,
'cart' => $proInfo,
'model' => $model,
));
}
}
And this is my "checkout.php" file in views:
<link rel="stylesheet" type="text/css" href="<?= Yii::app()->request->baseUrl ?>/css/cart.css"/>
<?php
$this->breadcrumbs = array(
'Giỏ hàng' => array('cart/index'),
'Thanh toán'
);
$this->pageTitle = "Thanh Toán";
$items = 0;
$total = 0;
$i = 0;
?>
<h1>Thanh toán</h1>
<?php
if (empty($cart)) {
echo "<p>Bạn chưa có sản phẩm nào trong giỏ hàng</p>";
} else {
$form = $this->beginWidget('CActiveForm', array(
'id' => 'payment-form',
// Please note: When you enable ajax validation, make sure the corresponding
// controller action is handling ajax validation correctly.
// There is a call to performAjaxValidation() commented in generated controller code.
// See class documentation of CActiveForm for details on this.
'enableAjaxValidation' => false,
));

But when submit that form it not direct to success page. I have try to insert die("abc") to each line in Controller and find out that it not run from the line
if($model->save()){....
How can I fix that now?
