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(); ?>
