php - 如何从 Laravel 中的 HTML 表中获取值

Question

我有一个动态排序表，我可以在其中添加或删除像 enter image description here 这样的行我的 Controller 中有一个循环。该循环根据表的列数运行 4 次。但是我的表有固定的列号和行号是可变的。我想根据行号运行这个循环。这是我的 View 页面

{!! Form::open(['action' => 'WorkBreakdownController@store', 'method' => 'POST', 'enctype' => 'multipart/form-data']) !!}
<table class="table table-hover table-sortable" id="tab_logic" name="DataTable">
                                <thead>
                                    <tr class="text-center">
                                        <td style="width: 40%;">Process Name</td>
                                        <td style="width: 30%;">Machine Name</td>
                                        <td style="width: 10%;">Machine Qty</td>
                                        <td style="width: 10%;">SMV</td>
                                        <td style="width: 10%;">Action</td>
                                    </tr>
                                </thead>
                                <tbody>
                                    <tr id='addr0' data-id="0" class="hidden">
                                        <td data-name="ProcessName">
                                            {{Form::text('items[][ProcessName]', '', ['id'=>'ProcessName', 'class' => 'form-control', 'placeholder'=>''])}}
                                        </td>
                                        <td data-name="MachineName">
                                            <div class="form-group row-fluid m-auto">
                                                <select name="items[][MachineName]" class="form-control" id="MachineName" data-live-search="true">
                                                    <option value=""></option>
                                                    @foreach($machineName as $machineName)
                                                        <option value="{{$machineName->id}}">{{$machineName->MachineName}}</option>
                                                    @endforeach
                                                </select>
                                            </div>
                                        </td>
                                        <td data-name="MachineQty">
                                        {{Form::number('items[][MachineQty]', '', ['id'=>'MachineQty', 'class' => 'form-control', 'placeholder'=>''])}}
                                        </td>
                                        <td data-name="SMV">
                                        {{Form::number('items[][SMV]', '', ['id'=>'SMV', 'class' => 'form-control', 'placeholder'=>''])}}
                                        </td>
                                        <td data-name="del">
                                            <a name="del0" id="del0" class="btn btn-outline-danger row-remove"  value="del0">Delete</a>                        
                                            {{-- <button name="del0" class='btn btn-outline-danger row-remove'>Delete</button> --}}
                                        </td>
                                    </tr>
                                </tbody>
                                
                                <tfoot>
                                    <tr>
                                        <td colspan="5" style="text-align: left;">
                                            <a id="add_row" class="btn float-right btn-lg btn-block btn-outline-secondary">Add Row</a>
                                        </td>
                                    </tr>
                                    <tr>
                                        <td colspan="5" style="text-align: left;">
                                            {{Form::submit('Save', ['class'=>'btn btn-lg btn-outline-primary btn-block', 'name'=>'ProductInsert'])}}
                                        </td>
                                    </tr>
                                </tfoot>
                            </table>

还有 Controller

$j=0;
            // $ProcessName_ID = $request->input('MachineName');
            foreach($request->input('items', []) as $item){
            $work_breakdown = new work_breakdown($item);
            $work_breakdown->SN = $j;
            $work_breakdown->ProcessName = $request->input("ProcessName{$j}");
            $work_breakdown->MachineID = $request->input("MachineName{$j}");
            $work_breakdown->MachineQty = $request["MachineQty{$j}"];
            $work_breakdown->SMV = $request["SMV{$j}"];
            $work_breakdown->user_id = auth()->user()->id;
            $work_breakdown->save(); 
            $j++;
            }

它只迭代了 4 次，不超过 taht。

假设您只存储文本数据而不是图像，并且您的 ajax post 调用是正确的，您只需在 Controller 中执行以下存储功能:

public function store(Request $request) {
  // I just call it device model here don't know your model name
  $device = Device::create($request->all());

  if($device) {
    return redirect()->route('device.index')->with('message', 'Success'); // return to device/index.blade.php with success message
  }

  return redirect()->route('device.index')->with('message', 'error'); // return to device/index.blade.php with error message

}
