I’m trying to apply a validation in my auth form. Everything works well, until I go into my return $this->sendFailedLoginResponse($request);, where the redirect()->back()->withErrors() isn’t storing the error in the MessageBag (making my $errors variable empty for my view).
laravel.blade.php
<!-- BEGIN LOGIN FORM -->
<form class="login-form" action="{{ url('/login') }}" method="post">
{!! csrf_field() !!}
<h3 class="form-title font-green">Iniciar sesión</h3>
@if (count($errors) > 0) // Here is where i check and my $errors variable is empty
@foreach ($errors->all() as $error)
<div class="alert alert-danger">
<button class="close" data-close="alert"></button>
<span>{{ $error }}</span>
</div>
@endforeach
@endif
<div class="form-group">
<!--ie8, ie9 does not support html5 placeholder, so we just show field title for that-->
<label class="control-label visible-ie8 visible-ie9">Username</label>
<input class="form-control form-control-solid placeholder-no-fix" type="text" autocomplete="on" placeholder="Usuario" name="email" value="{{ (isset($email) ? $email : '' ) }}" /> </div>
<div class="form-group">
<label class="control-label visible-ie8 visible-ie9">Password</label>
<input class="form-control form-control-solid placeholder-no-fix" type="password" autocomplete="off" placeholder="Contraseña" name="password" /> </div>
<div class="form-actions">
<button type="submit" class="btn green uppercase">Iniciar sesión</button>
</div>
</form>
<!-- END LOGIN FORM -->
AuthenticatesUsers.php
public function login(Request $request)
{
$this->validateLogin($request);
// If the class is using the ThrottlesLogins trait, we can automatically throttle
// the login attempts for this application. We'll key this by the username and
// the IP address of the client making these requests into this application.
$throttles = $this->isUsingThrottlesLoginsTrait();
if ($throttles && $lockedOut = $this->hasTooManyLoginAttempts($request)) {
$this->fireLockoutEvent($request);
return $this->sendLockoutResponse($request);
}
$credentials = $this->getCredentials($request);
if (Auth::guard($this->getGuard())->attempt($credentials, $request->has('remember'))) {
return $this->handleUserWasAuthenticated($request, $throttles);
}
// If the login attempt was unsuccessful we will increment the number of attempts
// to login and redirect the user back to the login form. Of course, when this
// user surpasses their maximum number of attempts they will get locked out.
if ($throttles && ! $lockedOut) {
$this->incrementLoginAttempts($request);
}
return $this->sendFailedLoginResponse($request);
}

最佳答案 你好你必须写如下redirect()
return redirect()->back()->with('status-keyword', 'error message');
在前端,您可以使用该消息
@if (session('error'))
<div class="alert alert-danger text-center msg" id="error">
<strong>{{ session('error') }}</strong>
</div>
@endif
我希望这对你有益.
谢谢.
