如何从第三个表中获取数据？

Question

我的问题有点复杂，我有表名char sentence[30]; int i=0; printf("Enter phrase: \n"); scanf("%c", sentence); while(sentence[i]!='.' && sentence[i]!='!') { i++; scanf("%c",&sentence[i]); } printf("%d\n", i); return i;

business, Items, busines_items and item_review.

我希望在业务视图中显示，business_items表中的business_items_id以及item_review表中该项目的评级。我已经做了一些工作，通过关系，我得到了business_items_id。但我如何从item_review获得评级。因此，当我转到此网址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. 时，此视图会向我显示该商家的所有产品及其评分和图片。

我在business / viewitems中的视图文件

localhost/project/business/products/business_id

业务模式

<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>

</div>
</div>
</div>
<?php    } ?>

Answer 1

任何对此答案感兴趣的人都会这样做。 我的业务控制器如下所示。

 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 
     ));
 }

现在我可以在我的viewitems视图中使用foreach循环来访问它。

foreach ($rate as $ba) {
    echo $ba->rating;
}

下面给出的是我的视图文件，我在其中获得针对特定业务和特定业务项的特定评级。

        <div class="container">

            <div class="container">
            <h1 class="page-title"><?php echo $model->business_name; ?>'s Products</h1>           <!-- add this heading in page-tittle -->
