结果将在laravel 5.7中的刀片文件中显示两次

我正在创建要根据通知状态和订单状态显示通知的任务。 从控制器仅获得三条记录，但在刀片文件中循环重复，两条记录两次。 正如预期的输出，我只想显示前三条记录，但它会再次重复第二条和第三条记录。如何消除这种混乱

控制器：

public function get_notification()
    {
        $userId=Session::get('userid');
       $data = DB::select('Select orders.product_id,subcategory.image,GROUP_CONCAT(subcategory.name_of_subcategory) as subcategory,orders.grand_total,orders.deliver_date,orders.order_status,orders.notification_status,orders.orders_id,orders.payment_status,orders.orders_date from orders inner join product_details on FIND_IN_SET(product_details.product_id,orders.product_id) > 0 inner join subcategory on product_details.sub_id=subcategory.sub_id where orders.user_id=? GROUP BY orders.product_id,orders.deliver_date,orders.order_status,orders.orders_id,orders.notification_status,orders.orders_date,orders.payment_status,orders.orders_subtotal,subcategory.image,orders.grand_total',[$userId]);
        return view('notification')->with('data',$data);
    }

刀片：

@foreach($data as $notification)


                    <div class="card-body noti-card" id="noti-card">
                        <div class="row mt-2">

重复最有可能来自查询。您能否在运行查询后立即使用Laravel helper方法

dump（）

或

dd（）

对结果进行确认？例如

dd（$data）

查询后，您可以立即查看查询返回的结果，并验证它们是否符合预期

我相信问题可能出在产品详细信息的连接上。使用

FIND\u in\u SET（）

的目的是什么

如果查询被分成多行，则更容易阅读和理解。如果切换到使用查询生成器，则可能更容易进行故障排除，如下所示：

$data = DB::table('orders')
    ->select([
        'orders.deliver_date',
        'orders.grand_total',
        'orders.notification_status',
        'orders.order_status',
        'orders.orders_date',
        'orders.orders_date',
        'orders.orders_id',
        'orders.payment_status',
        'orders.product_id',
        'subcategory.image',
        DB::raw('GROUP_CONCAT(subcategory.name_of_subcategory) as subcategory'),
    ])
    ->join('product_details', 'orders.product_id', '=', 'product_details.product_id')
    ->join('subcategory', 'product_details.sub_id', '=', 'subcategory.sub_id')
    ->where('orders.user_id', '=', $userId)
    ->groupBy(
        'orders.product_id',
        'orders.deliver_date',
        'orders.order_status',
        'orders.orders_id',
        'orders.notification_status',
        'orders.orders_date',
        'orders.payment_status',
        'orders.orders_subtotal',
        'subcategory.image',
        'orders.grand_total'
    )
    ->get();
