我的最后一个问题是如何在获得成功答案之后在其中一个视图中访问模型的数据。 This was my question
现在它的工作正常，但是当用户搜索数据库中不存在的business系统回显时，我怎么能回应呢？
业务不存在
我尝试在else循环中插入foreach，但它回应了＆＃34; Business not exist＆＃34;多次。
我在我的landing.php中发布用户搜索的商家名称，这是我searching视图的布局。
我正在粘贴我的Landing.php，业务控制器和我调用的Searching
我的landing.php：
<form action="business/searching" method="POST">
<div class="form-group form-group-lg">
<h2 class="title">
Find the best places to eat, drink, shop, or visit in Islamabad.
</h2>
<div class="col-sm-5 col-md-5 col-lg-5 col-md-offset-1">
<input type="text" class="form-control" name="business" id="lg" placeholder="I'm looking for...."/>
</div>
<div class="col-sm-3 col-md-3 col-lg-3">
<input type="text" class="form-control" id="sm" placeholder="Islamabad" disabled=""/>
</div>
<div class="col-sm-3 col-md-3 col-lg-3">
<input type="submit" class="btn btn-primary btn-lg"/>
</div>
</div>
</form>
在我的业务控制器中
public function actionSearching()
{
$models = Business::model()->findAll();
$modeladd = Address::model()->findAll();
$this->layout='//layouts/main';
$this->render(
'searching',
array(
'models' => $models,
'modeladd' => $modeladd,
)
);
}
搜索视图它有点复杂，但问我可以解释。

答案 0 :(得分：0)
如果你想在foreach循环中使用if else，你可以使用endif，end foreach循环。
<?php
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
//echo $_POST["business"]; echo "</br>";
//foreach($modeladd as $mo)
// {
//
// $street=$mo->street_number;
//
// $address=$mo->sector;
//
// $city=$mo->city;
// $business_id=$mo->business_id;
// echo $street; echo ("<br />");echo $address; echo ("<br />");echo $city; echo ("<br />");echo $business_id;
//}
