选择选项值未存储在数据库中

Question

Laravel 查看代码：

<tbody>
  @foreach($drycleaning as $drycleaning)
      <tr>
        <td class=""><input type="text" size="5" name="dc_{{$drycleaning->id}}"></td>
        <td class="">
            <div><div class="form-group">
            <select id="projectinput5" name="p_dc_{{$drycleaning->id}}" class="form-control">
            <option value="" selected>Price of</option>
            <option name="p_dc_{{$drycleaning->id}}" value="{{$prices->shirt}}">shirt</option>
            <option name="p_dc_{{$drycleaning->id}}" value="{{$prices->pant}}">pant</option>
            <option name="p_dc_{{$drycleaning->id}}" value="{{$prices->top}}">top</option>
            </select>
            </div></div>
        </td>
      </tr>
@endforeach
</tbody>

控制器代码：

public function store(Request $request)
{

  $bill = Bill::create([
  'waf_1' => $request->waf_1,
  'dc_1' => $request->dc_1,
  'dc_2' => $request->dc_2,
  'dc_3' => $request->dc_3,
  ...
  'p_dc_1' => $request->p_dc_1,
  'p_dc_2' => $request->p_dc_2,
  'p_dc_3' => $request->p_dc_3,
  ...
  ]);

  $bill->save();
  return redirect()->route('sp.orders.index');
}

由于foreach in view，输入和下拉选择显示3次。并且只有 3 个输入的输入值成功保存到数据库中，而不是选定的选项值。 谁能帮我理解我的代码错误？

这里有适合你的解决方案

在你的刀片中

<tbody>
    @foreach($drycleaning as $drycleaning)
        <tr>
            <td class=""><input type="text" size="5" name="dc[{{ $drycleaning->id }}]"></td>
            <td class="">
                <div><div class="form-group">
                    <select id="projectinput5" name="p_dc[{{ $drycleaning->id }}]" class="form-control">
                        <option value="" selected>Price of</option>
                        <option value="{{ $prices->shirt }}">shirt</option>
                        <option value="{{ $prices->pant }}">pant</option>
                        <option value="{{ $prices->top }}">top</option>
                    </select>
                </div></div>
            </td>
        </tr>
    @endforeach
</tbody>

在你的控制器中

public function store(Request $request)
{
    $data = array();
    $data['waf_1'] = $request->waf_1;

    foreach ($request->dc as $key => $value)
        $data['dc_'.$key] = $value;

    foreach ($request->p_dc as $key => $value)
        $data['p_dc_'.$key] = $value;

    $bill = Bill::create($data);
    return redirect()->route('sp.orders.index');
}

我会将名称属性设为数组，因为这样您就可以拥有任意数量的属性，并且您的 id 并不总是相同。希望这能让你继续前进：

@foreach($drycleaning as $drycleaning)
  <tr>
    <td class=""><input type="text" size="5" name="dc[]"></td>
    <td class="">
        <div><div class="form-group">
        <select id="projectinput5" name="p_dc[]" class="form-control">
        <option value="" selected>Price of</option>
        <option value="{{$prices->shirt}}">shirt</option>
        <option value="{{$prices->pant}}">pant</option>
        <option value="{{$prices->top}}">top</option>
        </select>
        </div></div>
    </td>
  </tr>

@endforeach

然后你可以在你的控制器中迭代
