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;
}
