使用paginate分页后数据处理

 1 public function index(){
 2     $sql = "";
 3     $list = "";
 4     $pagenumber = 20;//默认分页条数
 5     
 6     //查询数据
 7     $list = Db::name('wcmall_type','id,name,sort')->where($sql)->order('sort asc')->paginate($pagenumber,false,['query'=>request()->param()])->each(function($item, $key){
 8         $wctypeid = $item["id"]; //获取数据集中的id
 9         $num = Db::name('wcmall_type_attribute')->where("wctypeid='$wctypeid'")->count('id'); //根据ID查询相关其他信息
10         $item['num'] = $num; //给数据集追加字段num并赋值
11         return $item;
12     });
13     $page = $list->render();
14     
15     
16     return view('type/index',['list'=>$list,'page'=>$page,'title'=>'商品类型']);
17 }
