use frontend\models\Goods; //加载jidian 表的model

use yii\data\Pagination; //yii框架中使用分页

use frontend\web\myclass\QRcode;//加载生成二维码类

/**

class GoodsController extends Controller

   public $enableCsrfValidation = false;

   //商品展示列表

   //接收过来搜索的条件

   $w=yii::$app->request->get('goods_name');

   //分页

   $test=new Goods();   //实例化model模型

   $arr=$test->find()->where(['like','goods_name',"$w"]); //加上搜索的条件where

   $pages = new Pagination([



       'totalCount' => $arr->count(),

       'pageSize'   => 4 //每页显示条数

   ]);

   $models = $arr->offset($pages->offset)

       ->limit($pages->limit)

       ->all();

   return $this->render('goodslist', [ //前台的页面

       'data' => $models,
