How to get data from a third table? - php

Question

My question is bit complex, I have tables name business, Items, busines_items and item_review.
Business has attributes business_id,business_name
Items has attributes item_id (pk), item_name,item_price,item_description
Business_Items has attributes business_items_id (pk), Business_id (fk),item_id, image
Item_review has attributes item_review_id (pk), business_items_id (fk), rating.
I want to show in a view of business, business_items_id from business_items table and rating of that item from item_review table.I have done some work, Through relationship i get the business_items_id. But How can i get the rating from item_review. so that when i go to this url localhost/project/business/products/business_id this view shows me all the products of that business along with their ratings and picture.
My view file in business/viewitems
<div class="container">
<div class="container">
<h1 class="page-title"><?php echo $model->business_name; ?>'s Products</h1> <!-- add this heading in page-tittle -->
</div>
<?php $item=$model->businessItems;
?>
<div class="row row-wrap">
<?php foreach($item as $ba)
{
// echo $ba->id;
?>
<div class="col-md-3">
<div class="thumb">
<header class="thumb-header">
<a class="hover-img" href="<?php Yii::app()->request->baseUrl?>/businessitems/itemspage/<?php echo $ba->id; ?>">
<img src="<?php Yii::app()->request->baseUrl?>/img/<?php echo $ba->image;?>" alt="Image Alternative text" title="Items" />
</a>
</header>
<div class="thumb-caption">
<h5 class="thumb-title"><a class="text-darken" href="<?php Yii::app()->request->baseUrl?>/businessitems/itemspage/<?php echo $ba->id; ?>"><?php echo $ba->items->item_name; ?></a></h5>

Answer 1

Any one who is interested in the answer here it goes.
My business controller is given below.
public function actionViewitems($id)
{
//render main layout
$this->layout = 'main';
$rate = ItemReview::model()->findAll();
$this->render('viewitems', array(
'model' => $this->loadModel($id),
'rate' => $rate, //pass data
));
}
Now I can access it by using foreach loop in my viewitems view.
foreach ($rate as $ba) {
echo $ba->rating;
}
Now given below is my view file, where i am getting specific rating against specific business and specific business items.
<div class="container">
<div class="container">
<h1 class="page-title"><?php echo $model->business_name; ?>'s Products</h1> <!-- add this heading in page-tittle -->
