Yii-CHtmlPurifier－ 净化器的使用(yii过滤不良代码)

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(); ?>
