Yii控制器中filter過濾器用法分析

    本文實(shí)例講述了Yii控制器中filter過濾器用法。分享給大家供大家參考，具體如下：
    指定過濾動作，（如下projectContext()方法在新建，列表，管理頁面調(diào)用時(shí)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',
      );
    }
    添加一些過濾器邏輯，定義過濾方法，過濾方法前必加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,'請求和項(xiàng)目沒找到！');
        }
      }
      return $this->_project;
    }
    希望本文所述對大家基于Yii框架的PHP程序設(shè)計(jì)有所幫助。
