Yii如何过滤不良代码?本文主要介绍了Yii净化器CHtmlPurifier用法,可实现过滤不良代码的功能,涉及在控制器、模型、过滤器及视图中的相关使用技巧,需要的朋友可以参考下,希望对大家有所帮助。
具体如下:
1. 在控制器中使用:
public function actionCreate() { $model=new News; $purifier = new CHtmlPurifier(); $purifier->options = array( 'URI.AllowedSchemes'=>array( 'http' => true, 'https' => true, ), 'HTML.Allowed'=>'p', ); if(isset($_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(); $purifier->options = array( 'URI.AllowedSchemes'=>array( 'http' => true, 'https' => true, ), 'HTML.Allowed'=>'p', ); if(parent::beforeSave()){ if($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(); $purifier->options = array( 'URI.AllowedSchemes'=>array( 'http' => true, 'https' => true, ), 'HTML.Allowed'=>'p', ); if(isset($_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(); ?>
