这篇文章主要介绍了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
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。
