如何在laravel中显示来自MySql的数组数据

Question

所以我是一个Manifest，您可以在其中添加多个客户，生成等，并将其作为数组保存在数据库中

现在我正在创建一个页面，您可以在其中查看我希望它看起来像这样的所有清单信息

如果我尝试执行此类操作{{ $manifest->customer_name }}，我会收到错误htmlspecialchars() expects parameter 1 to be string, array given因为它是一个数组我只是在显示数组数据时遇到问题

控制器代码以获取正确的清单

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 - 通常我只会放{{ $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>
  @endforeach

Answer 1

您可以这样做：

@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

Answer 2

问题是您在数据库中存储数组（在PHP中是一个对象）。 这会使您在检索数据时无法识别表单。

在将数组存储到数据库之前，应将其序列化。它会将数据保存为一种JSON字符串。

serialize($array_var_name);

为了让阵列恢复，您可以使用

反序列化（$ data_var）;

现在您可以像往常一样使用数组
