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(); ?>

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
