如何在 laravel 中显示来自 MySql 的数组数据

Question

所以我是一个清单，您可以在其中添加多个客户、生产等，并将其作为数组保存在数据库中

现在我正在制作一个页面，您可以在其中查看所有清单信息我希望它看起来像这样

如果我尝试做这样的事情{{ $manifest->customer_name }} 我收到错误htmlspecialchars() expects parameter 1 to be string, array given 因为它是一个数组我只是无法显示数组数据

获取正确清单的控制器代码

public function view($id) {

    $manifests = Manifest::where('id', $id)->where('user_id', Auth::user()->id)->firstOrFail();

    return view('users.manifest.view', compact('manifests'));
}

查看 - 通常我只会输入 {{ $manifets->customer_name }} 但我不能，因为它是一个数组

<table class="table table-striped">
                        <thead>
                            <tr>
                                <th width="15%">Customer</th>
                                <th width="15%">Produce</th>
                                <th width="15%">Task</th>
                                <th width="15%">Units</th>
                            </tr>
                        </thead>
                        <tbody>
                            <tr>
                                <td>
                                    <input type="text" class="form-control" value="{{ $manifests->customer_name }}" />
                                </td>
                            </tr>
                        </tbody>
                    </table>

        <tr>

           </td>
           <td>
             <input type="text" class="form-control" value="{{ $manifest['produce'] }}" />
           </td>
           <td>
             <input type="text" class="form-control" value="{{ $manifest['task'] }}" />
           </td>
        </tr>
  @endforeach

Answer 1

你可以这样做：

@foreach($manifets as $manifestos)
   @for ($counter = 0; $counter < sizeof($manifestos['customer_name']); $counter++)
<tr>
   <td>

   <input type="text" class="form-control" name="nameoffield" value="{{ $manifestos['customer_name'][$counter] }}" />
   </td>
   <td>

   <input type="text" class="form-control" name="nameoffield" value="{{ $manifestos['otherfields'][$counter]}}" />
   </td>
   //more td here depending on the fields you want to display
</tr>
   @endfor
@endforeach
