YII框架中自带的表单，搜索，分页代码的实现

use yii\data\Pagination;

/**
* 搜索后分页
*/
public function actionList(){
$where=Yii::$app->request->get();
$query=new \yii\db\Query();
$query->from('user');
if(!empty($where['name'])){
$query->andWhere(['name'=>$where['name']]);
}
if(!empty($where['age1']) && $where['age1']!==""){
$query->andWhere(['>=','age',$where['age1']]);
}
if(!empty($where['age2']) && $where['age2']!==""){
$query->andWhere(['<=','age',$where['age2']]);
}
$users=$query->from('user')->all();
// var_dump($users);die;
$pages = new Pagination(['totalCount' =>$query->count(),'pageSize'=>'1']);    //实例化分页类,带上参数(总条数,每页显示条数)
$users = $query->offset($pages->offset)->limit($pages->limit)->all();
return  $this->render('list.php',['users'=>$users,'where'=>$where,'pages'=>$pages]);
}
}
