<!-- simple login form -->             {!! form::open(array('url' => '/auth/login')) !!}                  <div class="panel panel-body login-form">                     <div class="text-center">                         <div class="icon-object border-slate-300 text-slate-300"><i class="icon-reading"></i></div>                         <h5 class="content-group">login account <small class="display-block">enter credentials below</small></h5>                     </div>                     @if($errors->any())                         <div class="alert alert-danger no-border">                             username or password have entered incorrect                         </div>                     @endif                      <div class="form-group has-feedback has-feedback-left">                         {{form::text('username', null, array('class'=>'form-control', 'placeholder'=>'username'))}}                         <div class="form-control-feedback">                             <i class="icon-user text-muted"></i>                         </div>                     </div>                      <div class="form-group has-feedback has-feedback-left">                         {{form::password('password', array('class'=>'form-control', 'placeholder'=>'password'))}}                         <div class="form-control-feedback">                             <i class="icon-lock2 text-muted"></i>                         </div>                     </div>                      <div class="form-group">                         <button type="submit" class="btn btn-primary btn-block">sign in <i class="icon-circle-right2 position-right"></i></button>                     </div>                      <div class="text-center">                         <a href="login_password_recover.html">forgot password?</a>                     </div>                 </div>             {!! form::close() !!}             <!-- /simple login form --> 

routes

      route::get('auth/login', 'auth\authcontroller@getlogin');     route::post('auth/login', 'auth\authcontroller@postlogin');     route::get('auth/logout', 'auth\authcontroller@getlogout');       route::get('auth/register', 'auth\authcontroller@getregister');     route::post('auth/register', 'auth\authcontroller@postregister')  ;  

but getting following error

undefined variable: errors 

i didn't change else, want basic authentication. please me. else did miss?

make sure $middleware[]; array in app/http/kernel.php have following middleware registered:

\illuminate\view\middleware\shareerrorsfromsession::class, 

alternatively, can try registering routes of authentication under web middleware, such that:

route::group(['middleware' => ['web']], function () {     route::get('auth/login', 'auth\authcontroller@getlogin');     route::post('auth/login', 'auth\authcontroller@postlogin');     route::get('auth/logout', 'auth\authcontroller@getlogout');      route::get('auth/register', 'auth\authcontroller@getregister');     route::post('auth/register', 'auth\authcontroller@postregister'); } 

i hope work.
