在Laravel-5.8项目中，我正在处理动态输入表单。
主要模型是评估目标，而第二个模型是评估目的详细
控制器
public function create()
{
$goal = new AppraisalGoal();
$goaldetail = new AppraisalGoalDetail();
return view('appraisal.appraisal_goals.create')
->with('goal', $goal)
->with('goaldetail', $goaldetail) ;
}
public function store(StoreAppraisalGoalRequest $request)
{
DB::beginTransaction();
try {
$goal = new AppraisalGoal();
$goal->weighted_score = $request->weighted_score;
$goal->goal_title = $request->goal_title;
$goal->goal_description = $request->goal_description;
if ($request->appraisal_doc != "") {
$appraisal_doc = $request->file('appraisal_doc');
$new_name = rand() . '.' . $appraisal_doc->getClientOriginalExtension();
$appraisal_doc->move(public_path('storage/documents/appraisal_goal'), $new_name);
$goal->appraisal_doc = $new_name;
}
$goal->save();
foreach ( $request->activity as $key => $activity){
$startDate = Carbon::parse($request->start_date[$key]);
$endDate = Carbon::parse($request->end_date[$key]);
$insert_array = [
'kpi_description' => $request->kpi_description[$key],
'activity' => $request->activity[$key],
'start_date' => $startDate ->toDateTimeString(),
'end_date' => $endDate->toDateTimeString(),
];
AppraisalGoalDetail::create($insert_array );
}
DB::commit();
Session::flash('success', 'Goal is created successfully');
return redirect()->route(goals.index');
} catch (Exception $exception) {
DB::rollback();
Session::flash('error', 'Action failed! Please try again');
return redirect()->route('goals.index');
}
}

评估目标与评估目标细节无关。评估目标细节是一个数组。
应用程序的操作方式是，当用户单击提交按钮时，应用程序会保存到AppraisalGoal中，并选择其id，然后将其与其他数据一起保存到ApprenaisalGoalDetail中。
然而，验证存在问题。每当用户提交并验证页面时，在显示错误页面时，所有内容都变为空白，这意味着我需要再次输入它们。
我能够通过使用old((帮助函数来解决这些属于AppraisalGoal模型的问题，它很有效：
<div class="col-12 col-sm-6">
<div class="form-group">
<label class="control-label"> Goal Title:<span style="color:red;">*</span></label>
<input type="text" name="goal_title" value="{{ old('goal_title', $goal->goal_title) }}" placeholder="Enter goal title here" class="form-control">
</div>
</div>
<div class="col-sm-12">
<div class="form-group">
<label>Goal Description</label>
<textarea rows="2" name="goal_description" class="form-control" value="{{old('goal_description',$goal->goal_description)}}" placeholder="Enter Goal Description here ...">{{old('goal_description',$goal->goal_description)}}</textarea>
</div>
</div>
我不知道如何解决这些属于评估目标的问题详细信息：
<tr>
<td><input type="text" name="activity[]" class="form-control activity" ></td>
<td><input type="text" name="kpi_description[]" class="form-control kpi_description" ></td>
<td><input type="date" class="form-control start_date" placeholder="dd/mm/yyyy" name="start_date[]" min="{{CarbonCarbon::now()->firstOfYear()->format('Y-m-d')}}" max="{{CarbonCarbon::now()->lastOfYear()->format('Y-m-d')}}"></td>
<td><input type="date" class="form-control end_date" placeholder="dd/mm/yyyy" name="end_date[]" min="{{CarbonCarbon::now()->firstOfYear()->format('Y-m-d')}}" max="{{CarbonCarbon::now()->lastOfYear()->format('Y-m-d')}}"></td>
<td><a class="btn btn-danger remove"> <i class="fa fa-times"></i></a></td>
</tr>
如何更正此问题，即页面在提交和验证错误后仍应保留数据？
谢谢
当您得到验证错误&服务器出现故障。。您重定向页面&withInput((函数如下。。
return redirect()->route('goals.index')->withInput(['goal_title' => $request->goal_title, 'goal_description' => $request->goal_description]);
它将sork&显示您用于更新的价值
