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。
