本文实例讲述了Yii控制器中filter过滤器用法。分享给大家供大家参考，具体如下：

指定过滤动作，（如下projectContext()方法在新建，列表，管理页面调用时使用）

public function filters()

{

return array(

'accessControl', // perform access control for CRUD operations

'postOnly + delete', // we only allow deletion via POST request

'projectContext +create index admin',

);

}

添加一些过滤器逻辑，定义过滤方法，过滤方法前必加filter

public function filterProjectContext($filterChain)

{

$prijectId = null;

if(isset($_POST['pid'])){

$projectId = $_POST['pid'];

}elseif(isset($_GET['pid'])){

$projectId = $_GET['pid'];

}

$this->loadProject($projectId);

$filterChain->run();

}

public function loadProject($projectid)

{

if($this->_project === null){

$this->_project = Project::model()->findbyPK($projectid);

if($this->_project === null){

throw new CHttpException(404,'请求和项目没找到！');

}

}

return $this->_project;

}

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
