Question

我的表单中有多个选择列表的数组worker_id[]，如下所示：

<select multiple class="form-control" name="worker_id[]" size="8">
     @foreach($workers as $worker)
          <option value= ... </option>
     @endforeach
</select>

在我的控制器中，我想在循环中调用函数addRepairWorker，以便从worker_id数组中插入值。

if ($request->isMethod('post')) {
    $this->validate($request, [
            'worker_id' => 'required'
    ]);

    foreach ( arguments ){
            $this->repairsService->addRepairWorker($request, $vehicle);
    }
}

我需要在foreach中使用哪些参数？或者还有其他方式吗？我正在使用Laravel 5。

修改

这是addRepairWorker函数：

public function addRepairWorker(Request $request , Vehicle $vehicle){

        $workers_needed = null;
        DB::transaction(function () use ($request, $vehicle, $idcko) {

            $workers_needed = new Repair_worker();
            $workers_needed->repair_id = $idcko; //$idcko is DB query, not important here
            $workers_needed->worker_id = $request->worker_id;

            DB::insert('insert into repair_worker (repair_id, worker_id) values (?, ?)',
                    [$workers_needed->repair_id, $workers_needed->worker_id]);
        });
    }

Answer 1

我会更改函数本身以将任何已分配的worker_id插入到DB

中

所以在控制器中

if ($request->isMethod('post')) {
    // perform validation
    :

    // if all validations successful call function
    $this->repairsService->addRepairWorker($request, $vehicle);
}

现在该函数将处理多个worker_id值：

public function addRepairWorker(Request $request , Vehicle $vehicle){

    $worker_id_array = $request->input('worker_id');
    foreach ($worker_id_array as $worker_id) {

       DB::transaction(function () use ($request, $vehicle, $idcko) {

         $workers_needed = new Repair_worker();
         $workers_needed->repair_id = $idcko; //$idcko is DB query, not important here
         $workers_needed->worker_id = $worker_id;

         DB::insert('insert into repair_worker (repair_id, worker_id) values (?, ?)',
                [$workers_needed->repair_id, $workers_needed->worker_id]);
    });

   }
}

如果您希望该函数也可以作为单个值调用，只需添加一个检查输入是否为数组。

我不知道repairService的功能是什么，但我认为你正在尝试这个：

public function rules()
    {

       $rules = array();
        if(null !== $this->request->get('worker_id')){
            foreach ($this->request->get('worker_id') as $key => $val) {
                $rules['worker_id.' . $key] = 'required|integer';
            }
        }


            return $rules;
        }

这将为每个多个选定选项传递worker_id和车辆。

编辑：

您的验证也不正确。您不会验证这样的请求数组。

public function addRepairWorker($worker_id , Vehicle $vehicle){

        $workers_needed = null;


            $workers_needed = new Repair_worker();
            $workers_needed->repair_id = $idcko; //$idcko is DB query, not important here
            $workers_needed->worker_id = $worker_id;

            $workers_needed->save();

编辑2：

USER_DAYS[i]   = {
                   id: json[i].nrC,
                   date: json[i].dataD,
                   title: json[i].type,
                   start: new Date(json[i].startDate),
                   end: new Date(json[i].endDate),
                   allDay: true
                 }

循环遍历请求数组
