微信小程序 实现评论


 最近学习了微信小程序,于是乎,研究了一下评论功能。

首先我们的环境是:微信小程序+thinkphp6

上代码

微信小程序 jwt 登录:https://blog.csdn.net/lh25946/article/details/119044247?spm=1001.2014.3001.5501

表字段:order 订单表

 

 用户表:user

 

 评论表:loading

 

 点赞表:give

 

 商品名称表:good

 

 

列表页面:

/**
     * 订单列表数据
     */
    public function orderList(Request  $request)
    {
        //下拉加载分页
        $page = $request->get('page')??1;
        $limit = $request->get('limit')??5;
        $offset = ($page-1)*$limit;
        $id = 1;
        //查询不同状态下的订单
//        $allOrder = Order::with(['goods','user'])->where('user_id',$id)->limit($offset,$limit)->select();
        $received = Order::with(['goods','user'])->order('create_time asc')->where('user_id',$id)->limit($offset,$limit)->select();
        $notReceived = Order::with(['goods','user'])->whereOr('order_state',0)->where('user_id',$id)->limit($offset,$limit)->select();
        return json(['code'=>0,'msg'=>'成功','received'=>$received,'notReceived'=>$notReceived]);
    }

    /**
     * @param Request $request
     * @return \think\response\Json
     * 订单详情页面
     */
    public function orderDetail(Request $request)
    {
        $order_id = $request->get('order_id');
        try {
            $orderDetail = Order::with(['goods','user'])->find($order_id);
            $commentData = Loading::where('order_id',$order_id)->select();
            return json(['code'=>0,'msg'=>'成功','orderDetail'=>$orderDetail,'commentData'=>$commentData]);
        }catch (Exception $e){
            return json(['code'=>500,'msg'=>'内部错误']);
        }
    }
