I cannot get the "remember me" function on Laravel to work - php

Question

In my application I have made a login with “remember me” functionality. When I connect to the application with “remember me” it creates a remember token in the cookies. However, when I test and close the navigator with and without the remember me it behaves the same way.
I have read about Auth::viaRemember(), but I don’t know how to use it.
Here is my login:
public function postLogin()
{
$rules = array(
'email' => 'required|email',
'password' => 'required',
);
$validation = Validator::make(Input::all(), $rules);
if ($validation->fails())
{
return Redirect::to('login')->withErrors
($validation)->withInput();
}
$credentials = Input::only('email', 'password');
$remember = (Input::has('remember')) ? true : false ;
$email = Input::get('email');
$username = DB::table('users')
->where('email','LIKE',$email)
->pluck('email');
if( is_null($username)){
Session::flash('message', 'Votre login est invalide');
return Redirect::to('login');
}
else if (Auth::attempt($credentials, $remember)) {
return Redirect::intended('/');
}
else{Session::flash('message', 'Votre mot de passe est incorrect, veuillez réessayer'); }
return Redirect::to('login');
}
the view controller:
public function index()
{
if (Auth::check())
{
$theme = Theme::all();
$questions = questionList::paginate(10);
$the = "";
return View::make('home.home')
->with('user',Auth::user())
->with('theme', $theme)
->with('the' , $the)
->with('questions',$questions);
}
else
{
return Redirect::to('login')->with('message',"Vous devez vous connecter d'abord");
}
}
my user model:
<?php
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;
class User extends Eloquent implements UserInterface, RemindableInterface {
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'users';
/**
* The attributes excluded from the model's JSON form.
*
* #var array
*/
protected $hidden = array('password');
/**
* Get the unique identifier for the user.
*
* #return mixed
*/
public function getAuthIdentifier()
{
return $this->getKey();
}
/**
* Get the password for the user.
*
* #return string
*/
public function getAuthPassword()
{
return $this->password;
}
/**
* Get the token value for the "remember me" session.
*
* #return string
*/
public function getRememberToken()
{
return $this->remember_token;
}
/**
* Set the token value for the "remember me" session.
*
* #param string $value
* #return void
*/
public function setRememberToken($value)
{
$this->remember_token = $value;
}
/**
* Get the column name for the "remember me" token.
*
* #return string
*/
public function getRememberTokenName()
{
return 'remember_token';
}
/**
* Get the e-mail address where password reminders are sent.
*
* #return string
*/
public function getReminderEmail()
{
return $this->email;
}
}
