Question

亲爱的stackoverflow同事，

我很难从laravel返回一组数据。基本上我想要实现的是：

拥有一个用户数组（目前有2个用户）我正在遍历此数组并获取用户名。
使用此用户名，foreach名称我正在寻找它的ID并运行一个函数，该函数返回此用户帐户创建的每个订单的所述ID（仅限所述订单的总值）。

为每个用户返回如下对象：

{'username': name_in_the_array,'totalPrice': value,}

相反，我得到一个空结果，尽管$ data变量至少有1个值。

模型/控制器的代码和结果

public static function getOrdersUser($startDate, $endDate, $user){
    $orders = Order::whereBetween('orders.created_at', [new Carbon($startDate), new Carbon($endDate)])
        ->select(DB::raw('COALESCE(NULLIF(order_article_configurations.special_price, 0), order_article_configurations.price) * order_article_configurations.quantity AS totalPrice, orders.user_id'))
        ->join('order_articles', 'orders.id', '=', 'order_articles.order_id')
        ->join('order_article_configurations', 'order_articles.id', '=', 'order_article_configurations.order_article_id')
        ->where('orders.user_id', $user)
        ->where(function ($query) {
            $query->where('orders.is_quotation', '=', '0')
                ->orWhereNull('orders.is_quotation');
        })
        ->where(function ($query) {
            $query->whereNull('orders.deleted_at')
                ->orWhereNull('order_articles.deleted_at')
                ->orWhereNull('order_article_configurations.deleted_at');
        })
        ->get('totalPrice', 'orders.user_id');

    return $orders;
}

下一个控制器：

    public static function getOrdersUser(Request $request = null) {
    if (isset($request)) {
        $startDate = $request['start_date'];
        $endDate = $request['end_date'];
    } else {
        $startDate = Carbon::now()->subDays(30);
        $endDate = Carbon::now();
    }
    $users = ['merijn', 'stefan'];

    $data = null;
    $data = collect($data);
    $sum = 0;
    foreach($users as $user) {
        $userID = collect(DB::select("SELECT id FROM users WHERE username = '$user'"))->first();
        $userID = $userID->id;

        $data->username = $user;

        $value = Dashboard::getOrdersUser($startDate, $endDate, $userID);
        foreach ($value as $x) {

            $sum += $x->totalPrice;

        }

        $data->price = $sum;

    }

    return $data;
}

如果我在dd()上使用$data，则结果为：

Psy Shell v0.8.2 (PHP 7.1.7 — cli) by Justin Hileman
New version is available (current: v0.8.2, latest: v0.8.17)
>>> $x = App\Http\Controllers\DashboardController::getOrdersUser();
Illuminate\Support\Collection {#895
  #items: []
  +"username": "stefan"
  +"price": 258090.16
}

但return $data返回[]。

我希望得到的预期结果：

{ 'username':username,
  'price': total value }
{ 'username': next_username,
   'price': users total value

我感谢您的所有投入。谢谢
