Laravel复选框值

[英]Laravel checkbox value

问题描述

我是Laravel的新手，正在尝试从复选框中获取值。 我正在尝试接收创建报告所需的regeneration_id ，但是该值始终为null 。

视图： 

     @foreach ($regenerations as $regeneration)
                            @if ($regeneration -> invoice_id == NULL)

                            <tr>

                                <td>{{ $regeneration -> id }}</td>
                                <td>                  
                                  @if ($regeneration -> source == 1) Praca: {{ $regeneration -> source_id }}  
                                  @elseif ($regeneration -> source == 2) Sprzedaż: {{ $regeneration -> source_id }}
                                  @else Nieznane
                                  @endif </td>
                                <td>{{ $regeneration -> product_name }}</td>
                                <td>
                                  @if ($regeneration -> difficulty == 0) Nie ustalono
                                  @else {{ $regeneration -> difficulty }}
                                  @endif
                                </td>
                                <td>{{ $regeneration -> date_expected }}</td>

                             <td>     
                                <a href="{{ url ('actual',  $regeneration -> id ) }}">Szczegóły</a>
                             </td>
<form method="POST" action = "{{ action ('RegenerationsInvoicesController@generate')}}">
    {{csrf_field()}} 
                             <td>
                                  <div class="form-check">
                                  <input type="checkbox" name="regeneration[]" value = {{ $regeneration-> id }} ></input>
                                  </div>
                             </td> 
                             @endif 
                             @endforeach


                         </tr>

                      </table> 
               <button style="float: right;" type="submit" class= "btn btn-outline-success">Rozlicz</button>
</form>

控制器： 

public function generate (Request $req)
{
   $regeneration_id = Input::get('regeneration');
   var_dump($regeneration_id);
}

我正在尝试从复选框获取输入，但是它始终失败。 那是因为我的表格从@foreach之外开始吗？ 请帮忙。

路线： 

Route::post('/generateinvoice',RegenerationsInvoicesController@generate');

在这里试试 

public function generate (Request $req)
{
         $regeneration_id = $req->input('regeneration');
         var_dump($regeneration_id);
}

编辑的变更视图 

    @foreach ($regenerations as $regeneration)
                            @if ($regeneration -> invoice_id == NULL)

                            <tr>

                                <td>{{ $regeneration -> id }}</td>
                                <td>                  
                                  @if ($regeneration -> source == 1) Praca: {{ $regeneration -> source_id }}  
                                  @elseif ($regeneration -> source == 2) Sprzedaż: {{ $regeneration -> source_id }}
                                  @else Nieznane

谢谢大家为这个挑战付出的努力。 我终于找到了问题所在。 问题只在于视图。 我将表格放置的太远了，应该放在表格的开头。 正确的视图应该看起来像这样，并且可以正常工作。 

     <form method="POST" action = "{{ action ('RegenerationsInvoicesController@generate')}}">
  {{csrf_field()}} 

                     <table style="width:100%">

                            <tr>
                                <th>ID </th>
                                <th>Źródło</th>
                                <th>Produkt</th>
                                <th>Stopień trudności</th>
                                <th>Spodziewana data</th>
                                <th>Status</th>
                                <th>Cena</th>
                                <th></th>
                                <th>Rozlicz</th>
                            </tr>



                            @foreach ($regenerations as $regeneration)
                            @if ($regeneration -> invoice_id == NULL)

                            <tr>

                                <td>{{ $regeneration -> id }}</td>

</form>
