比如数据库的设计是下面这样子：

我想展示的是这个样子：

前端可以处理。

Think PHP的处理方式：

定义属性   ：

$this->customize = '任意值';//这里的之没有作用

<?phpnamespace app\hs\controller\shop;use app\daogou\model\Goods;
use app\hs\controller\Common;
use app\hs\traits\Curd;
use think\App;class Lists extends Common
{use Curd;public function __construct(App $app = null){parent::__construct($app);$this->model = new Goods();$this->alias = 'good';$this->join = ['user', 'user.id = good.user_id'];$this->field = 'good.*,username';$this->customize = 'status_txt';//        $good = $this->model->find();
//        dump($good);
//        $good->status_txt = '1112312';
//        dump($good);
//        dump($good->getData("price"));
//        die;}
}

在model 中定义 getXxxxAttr(){}  查询数据库会调用这个函数。对查出来的数据进行预处理

   public function getStatusTxtAttr($v,$data){//状态(-1:下架,1:上架,2:交易中)$status = [-1=>"下架",1=>"上架",2=>"交易中"];if(array_key_exists('status',$data)){return array_key_exists($data['status'],$status) ? $status[$data['status']] : $data['status'];}return '';}

<?phpnamespace app\daogou\model;use app\common\model\TimeModel;class Goods extends TimeModel
{protected $table = 'dg_goods';protected $type = ['type_params'=>'json',];//type_params://      type = 1 : [['coin_id'=>1,'award'=>"0.80000000"],……]//      type = 2 : ['max_number'=>10,'winner'=>1]//      type = 3 : nullpublic function user(){return $this->hasOne('user','user_id','id')->bind(['username']);}public function getStatusTxtAttr($v,$data){//状态(-1:下架,1:上架,2:交易中)$status = [-1=>"下架",1=>"上架",2=>"交易中"];if(array_key_exists('status',$data)){return array_key_exists($data['status'],$status) ? $status[$data['status']] : $data['status'];}return '';}public function getPriceAttr($v){return delZero($v);}
}
