Session is not setting after the user has hit remember me checkbox - php

Question

I have the cookie set and can see it in the console. When I close the browser and re-open it, it shows the cookie is there still , but not the session. So I am trying to see why my code is not keeping the user logged in. I will provide all the files necessary below.
EDIT: I should elaborate on this a little. So when the user close's his/her browser the session should no longer be there, but the cookie should and it is. So once that happens I want to say okay since there is a cookie we will grab that user's cookie look it up in the db and retrieve their id. Then using that id from a sessions table look up the id from the users table and log that user in.
login.php:
<?php
require_once 'core/init.php';
if(Input::exists()) {
if(Token::check(Input::get('token'))) {
$validate = new Validate();
$validation = $validate->check($_POST,array(
'username' => array('required' => true),
'password' => array('required' => true)
));
if($validation->passed()) {
$user = new User();
$remember = (Input::get('remember') === 'on') ? true : false;
$login = $user->login(Input::get('username'), Input::get('password'), $remember);
if($login) {
Redirect::to('index.php');
} else {
echo '<p>Sorry, logging in failed</p>';
}
} else {
foreach($validation->errors() as $error) {
echo $error, '<br>';
}
}
}
}

User.php: In this file under the public function login I put echo 'ok', and echo 'not ok' to see if my if was passing and I am getting 'no ok', so the if is not passing true. So my best guess is that $this->exists() is passing false. It should not be passing false though.
