On the error handling do this

<?php
class AccountController extends BaseController{
	//view form
	public function getCreate(){
		return View::make('account.create');
	}
	//get form information
	public function postCreate(){
		$validator = Validator::make(Input::all(),
			array(
				'email' 			=> 'required|max:50|email|unique:users',
				'username' 			=> 'required|max:20|min:3|unique:users',
				'password' 			=> 'required|min:6',
				'password_again' 	=> 'required|same:password'
			)
		);
		if ($validator->fails()) {
			return Redirect::route('account-create')
					->withErrors($validator)
					//saves input if redirect occurs because of error
					->withInput();

		}else{
			
			$email 		= Input::get('email');
			$username 	= Input::get('username');
			$password 	= Input::get('email');

			// Activation code
			$code		= str_random(60);
			//make fields fillable in User Model
			$user = User::create(array(
				'email'		=>	$email,
				'username'	=>	$username,
				//generate 60 varchar password
				'password'	=>	Hash::make($password),
				'code'		=>	$code,
				'active'	=>	0
			));

			if($user) {
				//code is passed to route which is then passed back to this controller and getActivate method
				Mail::send('emails.auth.activate', array('link' => URL::route('account-activate', $code), 'username' => $username), function($message) use ($user){
					$message->to($user->email, $user->username)->subject('Activate your account');
				});


				return Redirect::route('home')
						//global is message area on email template
						->with('global', 'Your account has been created! We have sent you an email to activate your account.');
			}
		}
	}

	public function getActivate($code) {
		return $code;
	}
}
