我的最后一个问题是在得到成功答案后，如何访问模型的一个视图中的数据。我实现了它。这是我的问题
现在它工作得很好，但当用户搜索数据库中不存在的business时，系统如何回应
业务不存在
我试图在foreach循环中插入else，但它多次回显"Business not exist"。
我在我的landing.php中张贴用户搜索的企业名称，这是我在searching视图中的布局。
我正在粘贴我的Landing.php、业务控制器和视图文件，我称之为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,
)
);
}
搜索视图有点复杂，但一经询问我可以解释。

如果您想在foreach循环中使用if-else，可以使用endif，end foreach循环。
<?php
/*
