Symfony cookie not sent (but in Response Header) - php

Question

I can't understand why my cookie isn't sent.
I've check all the thread about it and it seems that I'm doing it right.
I can't see the cookies in the Symfony debug, but not on my browser.
public function indexAction(Request $request)
{
$response = new Response();
$userID = $request->cookies->get('myCookie123');
if (empty($userID)) {
$uniqueID = $this->generateIDUtil();
$response->headers->setCookie(new Cookie('myCookie123', $uniqueID, 2147483647));
$response->sendHeaders();
}else{
var_dump('USER ALREADY KNOW <br>' );
}
var_dump($response->headers->getCookies()); //GIVES CORRECT COOKIE OBJECT
var_dump('<br>');
var_dump($request->cookies->all()); //GIVES ONLY PHPSESSID, BUT NOT THE ONE CREATED
var_dump('<br>');
var_dump($request->cookies->get('myCookie123')); //GIVES NULL
return $response->setContent($this->render('MyBundle:Core:index.html.twig'));
}

So here a working piece of code for anyone that want to get a userId from a cookie. With all the use statement and the twig rendering template.
The problem with the solution above is that it will give you a blank page as you send the header without rendering the view.
As it's really badly documented, here is a working solution.
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
class tempController extends Controller
{
public function indexAction(Request $request)
{
$user = $request->cookies->get('myCookie'); // $user is a string (the userID) or null if there is no cookie.
if (!empty($user)) {
//Fetch user data in the DB
}
// some code ...
$response = new Response();
if ($user instanceof User) {
// do some stuff like pre fill a form
}else{
// We don't know the user we send a cookie.
$cookie = new Cookie('myCookie', $this->generateIDUtil(), time() + (365 * 24 * 60 * 60)); // Expires 1 years
$response->headers->setCookie($cookie);
$response->sendHeaders();
}
//Render the view WITH the response (It's very important to put $response as 3rd parameter)
return $this->render('MyBundle:Core:index.html.twig', array(/* view param */), $response);
}
}

Here is how you properly create a cookie and send as a Response to a client:
$res = new Response();
$cookie = new Cookie(
'my_cookie',
$student->getStuId(),
time() + ( 2 * 365 * 24 * 60 * 60) // Expires 2 years.
);
$res->headers->setCookie( $cookie );
$res->send();
I use it all the time, so please let us know if you still have problems.
