循环收集

Question

如果我在视图中对$ payment进行了print_r，那么这就是我的结果;

Array
(
[0] => App\Models\Payment Object
    (
        [connection:protected] => 
        [table:protected] =>

        [with:protected] => Array

            )

        [morphClass:protected] => 
        [exists] => 1
    )

我正在尝试将结果打印到表格中。喜欢的东西;

@foreach($payments as $key => $payment)
  <tr>
     @foreach($payment as $subkey => $subpayment)
        <td>{{ $subkey }}</td>
    @endforeach
  </tr>
@endforeach

我不能让我的循环工作！我想打印出三个字段，表中每行一个。

我认为您正在寻找attributesToArray方法，该方法将模型的属性转换为关键数组，其中键是属性名称。这样的事情对你有用：

@foreach($payments as $payment)
  <tr>
    @foreach($payment->attributesToArray() as $value)
      <td>{{ $value }}</td>
    @endforeach
  </tr>
@endforeach
