One form and multiple models - yii

Question

I am using Yii Framework.
Purpose: Get user input and insert data into Order and OrderDetail tables on one form. The problem is data is inserted only into the Order table. I have tried to follow the wiki tutorial, but I can't fix this problem.
Why can't I insert data into both tables, Order and OrderDetail?
I have five models:
Customers(customer_id, customer_name, phone, email, lat, lng, ...)
Products(product_id, product_name,price, ...)
Order(order_id,customer_id, order_status, staff_id, ...)
OrderDetail(order_detail_id, order_id,product_id, qty, ...)
Staff(staff_id, staff_name, ...)
OrderController.php
public function actionCreate()
{
$model=new Order;
$orderdetail=new OrderDetail();
$product=new Products();
$date=date('y-m-d');
// Uncomment the following line if AJAX validation is needed
//$this->performAjaxValidation(array($model,$orderdetail));
if(isset($_POST['Order']))
{
$model->attributes=$_POST['Order'];
$model->lat='12.53';
$model->lng='13.2';
$model->completed_date=$date;
$model->received_date=$date;
$model->created_date=$date;
$model->upated_date=$date;
if($model->save())
if(isset($_POST['OrderDetail'])){
$orderdetail->attributes=$_POST['OrderDetail'];
$orderdetail->order_id= $model->order_id;
$orderdetail->order_item_status=1;
$orderdetail->created_date=$date;
$orderdetail->updated_date=$date;
if($orderdetail->save())
$this->redirect(array('view','id'=>$model->order_id));
}
//$OrderDetailController=new OrderDetail();
//$this->redirect(array('OrderDetail/create'));
}
$this->render('create',array(
'model'=>$model,
'orderdetail'=>$orderdetail,
'product'=>$product,
));
}
views/order/create.php
<?php
$this->breadcrumbs=array(
'Orders'=>array('index'),
'Create',

$this->menu=array(

Answer 1

A form which handles two models... Create a form which has all the attributes for the two models and then in the view when the form is posted and valid save the attributes into two the models.
if(isset($_POST['ModelOneAndModelTwoForm']))
{
$form->attributes=$_POST['ModelOneAndModelTwoForm'];
if($form->validate())
{
$modelOne = new ModelOne();
$modelOne->save();
$modelTwo = new ModelTwo();
$modelTwo->save();
}
}
