我有一个联系表格，当提交时，它将成功地转到DB。问题是，当我在网页上检查验证时，使用larvael $错误验证正确出现错误时，问题在于，当出现错误时，我的网页始终将其重定向回家，而不是剩下的页面静止不动并显示错误。我必须继续向下滚动到我的联系表所在的位置，以查看错误。这对我未来的用户来说会很烦人。如果有错误，我该如何将页面保留在哪里？注意：当表单有效并提交时，我的页面正确重定向，这不是问题。注释：我创建了一个Nav-Link带您到达的单页网页，没有重定向。相反，它是一个HTML页面。

您需要创建一个手动验证器，以便如果验证失败，则可以控制重定向(我认为这是您遇到的问题(。
public function submit(Request $request)
{
$validator = Validator::make($request->all(),[
'name' => 'required|min:2',
'email' => 'required|max:255',
'phonenumber' => 'required|min:10|max:10',
'message' => 'required|min:5',
]);
if ($validator->fails()) {
return redirect(url()->previous() .'#contact')
->withErrors($validator)
->withInput();
}
Message::create($request->all());
return redirect('/')->with('success', 'Your message has been
successfully sent. We will reach out to you soon');
}
首先，将错误移至表单的顶部，以便您可以看到它们。
<form action="/contact/submit" method="POST">
@csrf
@if($errors->any())
<div class="notification is-danger">
<ul>
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
</ul>
</div>
@endif
更好地处理验证的方法是使用表单请求进行分开。
php artisan make:request SendMessageRequest
namespace AppHttpRequests;
use IlluminateFoundationHttpFormRequest;
class SendMessageRequest extends FormRequest
{
public function authorize()
{
return true;
}
public function rules()
{
return [
'name' => 'required|min:2',
'email' => 'required|max:255',
'phonenumber' => 'required|min:10|max:10',
'message' => 'required|min:5',
];
}
}
如果验证失败，将自动生成重定向响应，以将用户发送回他们以前的位置。
现在更新您的控制器。
use AppHttpRequestsSendMessageRequest;
use AppMessage;
class MessagesController extends Controller
{
public function submit(SendMessageRequest $request)
{
Message::create($request->validated());
return redirect('/')->with('success', 'Your message has been
successfully sent. We will reach out to you soon');
}
}
您可以使用Validator和back()重定向将验证保留在控制器中，但第一个是更好的方法。
public function submit(Request $request)
{
$validator = Validator::make($request->all(), [
'name' => 'required|min:2',
'email' => 'required|max:255',
'phonenumber' => 'required|min:10|max:10',
'message' => 'required|min:5',
]);
if ($validator->fails()) {
return back()->withInput()->withErrors($validator);
}
Message::create($request->all());
return redirect('/')->with('success,' 'Your message has been
successfully sent. We will reach out to you soon');
}
