Question

我有多行表单，我想将每行的某些列保存到数据库中，但是当我按Submit时，我得到了空白页，并且没有错误。我的表格：

    {!! Form::open(['route' => ['updateHelper'], 'method' => 'POST','id'=>'beforeSubmitO']) !!} 
        <table class="table table-striped operatives" id="checkTableO" dir="rtl">
            <thead>
                <tr>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>                             
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                    <th>XXX</th>
                </tr>
            </thead>
            <tbody id="myDIV">
                @foreach($operatives as $operative)
                    <tr>
                        <td class="selected"><a href="{{route('showHelper',['id'=>$operative->id,'emp_id'=>$operative->employee_no])}}" onclick="myscrollfun()" >
                                {{$operative->employee_no}}</a>
                        </td>
                        <td>{{$operative->employee_name}}</td>
                        <td>{{$operative->start_date_of_work}}</td>
                        <td>{{$operative->company}}</td>

                        <td dir="ltr">{{$operative->before_previous_month}}</td>
                        <td dir="ltr">{{$operative->previous_month}}</td>
                        <td dir="ltr">{{$operative->current_month}}</td>
                        <td dir="ltr">{{$operative->gross_difference}}</td>
                        <td dir="ltr">{{$operative->net}}</td>
                        <td>{{$operative->risk_level}}</td>
                        <td><textarea class="comment" id="comment" type="text" name="comment[]" rows="1" cols="23">{{$operative->comment}}</textarea></td>
                        <td><input {{old('is_proper[]',$operative->isproper)=="V"? 'checked':''}} type="checkbox" class="isproper"  name="is_proper[]" value="V" /></td>

                        <td>
                            <select class="check" name="rescoring[]">
                                <option {{old('rescoring[]',$operative->rescoring)=="לא"? 'selected':''}} value="לא" selected>לא</option>
                                <option {{old('rescoring[]',$operative->rescoring)=="כן"? 'selected':''}} value="כן">כן</option> 
                            </select>
                        </td>
                        <td dir="ltr">{{$operative->user_name}}</td>
                        <td><input type="hidden" name="oper_id[]" value="{{$operative->id}}"></td>
                        <td><input class="checkboxVal" type="hidden" name="checkbox_val[]" value=''></td>
                    </tr>
                @endforeach
                    <p class="row justify-content-center pagination">{{$operatives->links()}}</p> 
            </tbody>
        </table>
        {{Form::hidden('_method','PUT')}}
        {{Form::submit('save',['class'=>'btn btn-primary float-right','id'=>'save', 'onclick'=>'myscrollfun()'])}}
    {!! Form::close() !!}

我的路线：

Route::put('/operatives',[
    'as' => 'updateHelper',
    'uses' => 'OperativesController@update'
]);

控制器更新功能：

    public function update(Request $request)
    {
        $oper_id = $request->oper_id;
        $comment = $request->comment;
        $rescoring = $request->rescoring;
        $checkboxVal = $request->checkbox_val;

        foreach($oper_id as $key => $value){
            $operative = Operative::find($value);
            $operative->comment = $comment[$key];
            $operative->rescoring = $rescoring[$key];
            if($checkboxVal[$key] == ''){
                $operative->isproper = '';  
            }
            else{
                $operative->isproper = $checkboxVal[$key];
            }

            $operative->save();
        }

        return back()->with('success','Updated'); 
    }

在localhost上一切正常，但在服务器上显示空白页。

我尝试在服务器上检查我的php.ini-“ post_max_size”和“ max_input_vars”，但与本地主机上的一样。

有人知道为什么吗？我在做什么错了？

Answer 1

什么都不显示的原因是您实际上没有重定向回去。您需要在back()帮助器（或redirect()模型）上调用Redirect方法。

在您的update()方法中，替换

return back()->with('success','Updated');

使用

return redirect()->back()->with('success','Updated');

您还应该指定表单处理一个PUT请求，您可以通过将表单中的method属性设置为'PUT'而不是'POST'来完成此请求。 / p>

'method' => 'PUT'

按提交后的空白页
