【问题描述】：

成功付款后，我正在尝试将查询的结果从我的数据库打印到视图中。但是，当我尝试访问传递给视图的数据时，出现以下错误

Property [order_number] does not exist on this collection instance.

我已经在集合上做了var_dump，它返回了属性和值，但是当我尝试像$orderDetails->column_name那样访问它时，我得到一个错误

下面是我的方法

  public function complete(Request $request)
{

    $paymentId = $request->input('paymentId');
    $payerId = $request->input('PayerID');

    $status = $this->payPal->completePayment($paymentId, $payerId, $request->order_number);

    $order_number = $request->order_number;

    $order = Order::where('order_number', $order_number)->first();
    $order->status = 'processing';
    $order->payment_status = 1;
    $order->payment_method = 'PayPal';
    $order->save();

    Cart::clear();

    $orderDetails = Order::where('order_number', $order_number)->get();

    return view('frontend.pages.order-success', [
        'orderDetails' => $orderDetails
    ]);

    // return redirect()->route('/')->with('message', 'Your Order has been placed successfully! We will contact you with the details you provided');
}

这是我的查看页面

    @extends('frontend.layouts.main')

    @section('title', 'Order Successful')

 @section('content')
 <!-- Main Content -->
 <div id="main-content" class="site-main clearfix">

     <section class="order-detail themesflat-section">

【问题讨论】：

$orderDetails 是一个集合，而不是单个记录。使用first() 而不是get()，或者在你的刀片上使用一个环。
$order 是一个带有订单的变量，$orderDetails 是一个只有 1 个项目的集合，相同的订单。我建议阅读 Eloquent 文档。
会不会是$request->input('order_number'); 和其他从请求中获取数据的尝试一样？

【解决方案1】：

您试图从集合中获取属性，而不是从单个项目中获取属性，那么它将不起作用。

改变：

$orderDetails = Order::where('order_number', $order_number)->get();

作者：

$orderDetails = Order::where('order_number', $order_number)->firstOrFail();
