Laravel 8-旧输入和验证错误消息不起作用
如果对某一输入的验证与指定字段上的上一次输入一起失败,我会尝试在该字段下方显示错误div。
以下是我到目前为止的进展:
在我的controller
文件中store
函数(UserController > store)
:
public function store(Request $request)
{
$validationRules = array(
'first_name' => 'required|min:2|max:150',
'last_name' => 'required|min:2|max:150',
'gender' => 'required',
'birthdate' => 'required',
'user_contact' => 'required|min:10|max:20',
'email' => 'required|unique:users|max:150'
);
$validator = Validator::make($request->all(), $validationRules);
if($validator->fails()){
//dd($validator)
return redirect(route('user.create'))->withInput()->withErrors($validator);
}
.....
当我尝试使用dd()
打印$validator
时,它没有任何问题,并且它包含验证错误消息、所有输入和验证规则。
以下是create.blade.php (view)
:
<form class="form-horizontal" method = "POST" action = "{{ route('user.store') }}">

请注意,我删除了autocomplete=off
,因为我阅读了一些帖子,认为这会导致问题,但在我的情况下仍然不起作用。
我已经阅读了所有与我的问题相关的Stackoverflow帖子,但大多数场景问题都发生在Laravel 5上,我使用的是Laravel框架的最新版本,也就是Laravel 8。
问题的原因似乎是什么?以及我应该如何保留 旧/以前的输入,并在失败后显示错误消息 验证?我怀疑问题出在刀片式服务器上 文件或与引导等资源相关的文件。
解决方案
您可以尝试此重定向
if ($validator->fails())
{
return redirect()->back()->withErrors($validator->errors());
}
在刀片文件中显示时,尝试这个
@error('user_contact')
<div style="color: red;">{{ $message }}</div>
@enderror
