Maybe:

->with(array("messages"=>$this->user->errors));

still

Undefined variable: messages (View: 

but i found that in the docs but i cant get it [This is a link]http://laravel.com/docs/validation under named error

Named Error Bags If you have multiple forms on a single page, you may wish to name the MessageBag of errors. This will allow you to retrieve the error messages for a specific form. Simply pass a name as the second argument to withErrors: return Redirect::to('register')->withErrors($validator, 'login');

Why do you want to do that ?

i found it .. second reply here http://stackoverflow.com/questions/17047116/laravel-validation-attributes-nice-names

return Redirect::route('page')->withErrors(array('register' => $validator));

so i will get it under

{{$errors->register->first('username)}}

i had 2 forms one for login and other for sign up in one page so the variable $errors->first('username') is identical for login and sign up

now i get that error :D http://oi59.tinypic.com/e7kqpw.jpg
