将 javascript html 代码附加到刀片模板时发生错误

Question

错误

htmlspecialchars() expects parameter 1 to be string, array given (View: D:\Codes\Php\Laravel\appoint_now-master1\resources\views\staff\schedule\edit.blade.php) 

刀片代码

<form action="{{route('staff.schedule.AddHour',$day->id)}}" method="post"  id="formHours-{{ $day->id }}"  >
 @csrf
@method('put')
<input type="hidden"  value="{{$day->id}}" name="staff_schedule_day_id" required>
</form>

控制器代码

public function addHour(Request $request,$staffSchedule)
    {
        $user = auth()->guard(GuardType::STAFF)->user();

        $request->validate([
            'staff_schedule_day_id' => 'required',
            'start_time' => 'required',
            'end_time' => 'required',
        ]);

        $staffSchedulesDaysHours=new StaffScheduleDayHour();
        $staffSchedulesDaysHours->staff_schedule_day_id = $request->staff_schedule_day_id;
        $staffSchedulesDaysHours->start_time = $request->start_time;
        $staffSchedulesDaysHours->end_time = $request->end_time;
        $staffSchedulesDaysHours->save();


       

return view('staff.schedule.edit')->with('success', trans('messages.itemUpdated'));
    }

javascript

 function addHour(day_id)
                {
                    const id = `hour-${makeId(5)}`;
                    let html = "";
                    html += `<div class="input-group" id="${id}">`;
                    html += `<input type="time" class="form-control " value="" name="start_time[]"  required>`;
                    html += `<input type="time" class="form-control " value="" name="end_time[]"  required>`;
                    html += `<div class="input-group-append">`;
                    html += `<button class="btn btn-danger"  type="submit">`;
                    html += `Submit`;
                    html += `</button>`;
                    html += `<button class="btn btn-danger" type="button" onclick="removeHour('${id}')">`;
                    html += `<i class="fa fa-trash fa-fw"></i>`;
                    html += `</button>`;
                    html += `</div>`;
                    html += `</div>`;

                    $(`#formHours-${day_id}`).append(html);
                }

我尝试将 start_time 和 end_time 作为数组添加到我的数据库表 schedule_hours，因为 json 对象表列设置为 start_time 和 end_time 的 jason 对象。当我按下提交按钮时，它显示错误。 我忘了说小时模型也被保护为 start_time 和 end_time 的数组变量。我不知道错误来自哪里。请帮帮我

尝试将$request->start_time 转换为json，然后再将其存储到数据库中。 使用

$staffSchedulesDaysHours->start_time = json_encode($request->start_time);
$staffSchedulesDaysHours->end_time = json_encode($request->end_time);
