Question

您好我无法正确显示MySQL的JSON数据，我需要单独访问JSON中每个项目的'SKU'和'qty'键。我的代码如下所示：

// dummy data save

$order_items = array();
for ($i = 0; $i < 5; $i++) {
  array_push($order_items, array('SKU' => $item_sku, 'qty' => 1));
}
$order->items = $order_items;

$order->user_id = Auth::id();

$order->save();


// 'items' field in MySQL

[{"SKU": "CM10361", "qty": 1}, {"SKU": "CM10361", "qty": 1}, {"SKU": "CM10361", "qty": 1}, {"SKU": "CM10361", "qty": 1}, {"SKU": "CM10361", "qty": 1}]


// controller 

$orders = Order::with('orderAuthor')->orderBy('id', 'desc')->get();


// blade view code

{{ json_encode($orders->first()->items) }}


// blade output

  [{"SKU":"CM10361","qty":1},{"SKU":"CM10361","qty":1},{"SKU":"CM10361","qty":1},{"SKU":"CM10361","qty":1},{"SKU":"CM10361","qty":1}]

如何访问'SKU'和'qty'键？喜欢$items->SKU？

Answer 1

在您的视图中，您有一个集合，尝试通过方法each迭代项目，如下所示：

$orders->each(function ($item, $key) {
  //here your stuff
});

Answer 2

// controller 

$orders = Order::with('orderAuthor')->orderBy('id', 'desc')->get();

//loop through results

foreach ($orders as $order)

{
  //now decode the json
  $decoded_order = json_decode($order);
  echo $sku      = $decoded_order->SKU;

}

Answer 3

我不明白为什么你是json_encoding视图上的items对象（即你将它转换为字符串），当你真的想要作为一个数组访问它时。我猜测items列是可变的（Laravel自动编码/解码），所以如果这是正确的，我认为你应该这样做：

@foreach ($orders->first()->items as $item)
    {{ $item['SKU'] }}
@endforeach

Answer 4

这是正确的解决方案，最后

@foreach ($orders as $order)
    @foreach ($order->items as $item)
         {{ $item['qty'] }}
    @endforeach
@endforeach

Answer 5

//loop through results
@foreach ($orders as $orderKey=>$orderValue)
        $sku = $orderValue->SKU;
        $qty = $orderValue->qty;
        <tr>
                <td>{{$sku}}</td>
                <td>{{$qty}}</td>
        </tr>
@endforeach
