本文实例讲述了Yii净化器CHtmlPurifier用法。分享给大家供大家参考,具体如下:
1. 在控制器中使用:
public function actionCreate() { $model=new News; $purifier = new CHtmlPurifier(); $purifier->options = array( "URI.AllowedSchemes"=>array( "http" => true, "https" => true, ), "HTML.Allowed"=>"div", ); if(isset($_POST["News"])) { $model->attributes=$_POST["News"]; $model->attributes["content"] = $purifier->purify($model->attributes["content"]); if($model->save()) $this->redirect(array("view","id"=>$model->id)); } }
2. 在模型中的使用:
protected function beforeSave() { $purifier = new CHtmlPurifier(); $purifier->options = array( "URI.AllowedSchemes"=>array( "http" => true, "https" => true, ), "HTML.Allowed"=>"div", ); if(parent::beforeSave()){ if($this->isNewRecord){ $this->create_data = date("y-m-d H:m:s"); $this->content = $purifier->purify($this->content); } return true; }else{ return false; } }
3. 在过滤器中的使用:
public function filters() { return array( "accessControl", // perform access control for CRUD operations "postOnly + delete", // we only allow deletion via POST request "purifier + create", //载入插入页面时进行些过滤操作 ); } public function filterPurifier($filterChain){ $purifier = new CHtmlPurifier(); $purifier->options = array( "URI.AllowedSchemes"=>array( "http" => true, "https" => true, ), "HTML.Allowed"=>"div", ); if(isset($_POST["news"]){ $_POST["news"]["content"] = $purify($_POST["news"]["content"]); } $filterChain->run(); }
4. 在视图中的使用:
<?php $this->beginWidget("CHtmlPurifier"); ?> ...display user-entered content here... <?php $this->endWidget(); ?>
