当我将文本字段留空时，我在一个视图中有两个表单，它会重定向到错误的操作。我正在寻找转发这个问题的解决方案。谢谢你。 当我在输入字段中输入数据时，表单1正常工作。 / inquiry / store还包含http请求验证。
查看包含两种表单的代码。
private func performVisionRequest(pixelBuffer: CVPixelBuffer){
let visionModel = try! VNCoreMLModel(for: self.iFaceModel.model)
let visionModel2 = try! VNCoreMLModel(for: self.ageModel.model)
let request = VNCoreMLRequest(model: visionModel){ request, error in
if error != nil {
return
}
guard let observations = request.results else {
return
}
let observation = observations.first as! VNClassificationObservation
print("Name \(observation.identifier) and confidence is \(observation.confidence)")
DispatchQueue.main.async {
if observation.confidence.isLess(than: 0.04) {
self.displayPredictions(text: "Not recognized")
print("Hidden")
}else {
self.displayPredictions(text: observation.identifier)
}
}
}
搜索学生的第二种形式。当我提交第一个表单而没有一些空字段时，它会重定向到/ inquiry / search_stu。并显示MethodNotAllowedHttpException。

当我提交商店表单时，它会重定向到搜索学生。
存储功能。
public function search_student(Request $request)
{
$teacher = \App\Teacher::lists('name', 'name');
$adminid = $request['search'];
$student = Admission::where('admission_no',$adminid)->first();
return View::make('/inquiry/create', ['student'=> $student,'teacher' => $teacher]);
}
想要存储数据时的Http请求验证
public function store(Requests\StoreInquiryRequest $request) {
$input = Input::all();
$inquiry = new Inquiry();
$inquiry->name = $input['name'];
$inquiry->father_name = $input['father_name'];
$inquiry->date = $input['date'];
$inquiry->class = $input['class'];
$inquiry->teacher_name = $input['teacher_name'];
$inquiry->roll_no = $input['roll_no'];
$inquiry->remarks = $input['remarks'];
try {
$inquiry->save();
return redirect()->to('inquiry')->with('message', 'success| Student details have been saved.');
} catch (Exception $ex) {
\Log::error($ex);
return redirect()->to('inquiry')->with('message', 'error| There was an error adding new student, please try again later.');
}
}

您可以根据需要在一个页面上执行尽可能多的表单。据我所知，你的控制器应该有适当的验证 - 对每个表格进行不同的验证。
您需要使用正确的Laravel验证。阅读此内容可使您的编码过程更轻松，更快捷：https://laravel.com/docs/5.0/validation
Laravel 5.0中控制器的验证示例：
public function store(Request $request)
{
$this->validate($request, [
'title' => 'required|unique|max:255',
'body' => 'required',
]);
}
Laravel Valiation还允许您通过查询数据库qithout编写整个SQL查询来执行验证：https://laravel.com/docs/5.0/validation#available-validation-rules
要在视图中显示错误：
@if($errors->has())
@foreach ($errors->all() as $error)
<div>{{ $error }}</div>
@endforeach
@endif
