Yii凈化器CHtmlPurifier用法示例(過濾不良代碼)

字號:


    這篇文章主要介紹了Yii凈化器CHtmlPurifier用法,可實現(xiàn)過濾不良代碼的功能,涉及在控制器、模型、過濾器及視圖中的相關(guān)使用技巧,需要的朋友可以參考下
    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. 在過濾器中的使用:
    public function filters()
    {
      return array(
        'accessControl', // perform access control for CRUD operations
        'postOnly + delete', // we only allow deletion via POST request
        'purifier + create', //載入插入頁面時進(jìn)行些過濾操作
      );
    }
    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. 在視圖中的使用:
    <?php $this->beginWidget('CHtmlPurifier'); ?>
    ...display user-entered content here...
    <?php $this->endWidget(); ?>
    希望本文所述對大家基于Yii框架的PHP程序設(shè)計有所幫助。
