YII页面跳转

$criteria = new CDbCriteria;
$criteria->select = array('ziduan");
$res = Model::model()->findAll($cirteria);

　　

搜某一个字段

//当前域名 echo Yii::app()->request->hostInfo;
//当前URLecho Yii::app()->request->getUrl();
//返回首页 echo Yii::app()->user->returnUrl;

//提交后 防止重复提交
Ccontroler->refresh();

//上一页url  很有用哦
Yii::app()->request->urlReferrer;

//获取ip地址 
Yii::app()->request->userHostAddress; 
//yii execute后获取insert id 
$id = Yii::app()->db->getLastInsertID(); 
//yii获取get,post过来的数据 
Yii::app()->request->getParam('id'); 
//Yii->user（当前用户）相关 

常用方法是
class Controller extends CController 
{ 
　　public $user = null; 
　　$this->user = Yii:app()->user; 
} 
　　this->user->isGuest; 
　　this->user->id; 
　　this->user->name;
