JSON解码-解码购物车PHP

Question

你好，我在Laravel 5.4中工作。我用json_encode将购物车保存到数据库中，这没有问题。我的问题是在我的视图中获取我想要的数据。例如，我想显示产品的名称和价格。

我试过了：

  @foreach ($order->cart->items as $item)
         {{ dd(json_decode($order->cart, true)) }}
        {{ $item['price']['title'] }}
   @endforeach

这就是我得到下一个错误的时候：

Trying to get property of non-object

当我扔掉我的手推车

dd(json_decode($order->cart, true))

我得到了：

array:3 [▼
  "items" => array:1 [▼
    5 => array:4 [▼
      "id" => 5
      "qty" => 1
      "price" => 15
      "item" => array:8 [▼
        "id" => 5
        "created_at" => "2017-06-05 13:21:45"
        "updated_at" => "2017-06-05 13:21:45"
        "imagePath" => "https://someImage"
        "title" => "Vitamin B-12"
        "discription" => "Vitamin B-12, also called cobalamin ▶"
        "category" => 4
        "price" => 15
      ]
    ]
  ]
  "totalQty" => 1
  "totalPrice" => 15
]

您的$order->cart是一个数组，而不是一个对象。试试这个：

<?php $data = json_decode($order->cart, true); ?>
@foreach ($data['items'] as $item)
    {{ $item['item']['title'] }} {{ $item['item']['price'] }}
@endforeach
