Read and Write Cookie in Symfony2

Question

I want to store some information in the local browser cookie. After hours looking for a nice tutorial, I managed to store some data in a non-session cookie:

controller - indexAction()

$cookieGuest = array(
    'name'  => 'mycookie',
    'value' => 'testval',
    'path'  => $this->generateUrl('my_route'),
    'time'  => time() + 3600 * 24 * 7
);

$cookie = new Cookie($cookieGuest['name'], $cookieGuest['value'], $cookieGuest['time'], $cookieGuest['path']);

$response = new Response();
$response->headers->setCookie($cookie);
$response->send();

I wonder if this is the correct way. Furthermore I tried several ways to read the cookie with the HttpFoundation Component, but without success. Is there another way than accessing the cookie via $_COOKIE['mycookie'] ?

Here is where I try to read the cookie

controller - cookieAction()

public function cookieAction($_locale, $branch, $page) 
{   
    $response = new Response();
    $cookies = $response->headers->getCookies();

    var_dump($cookies);

// TODO: Get params for indexAction from cookie if available

    return $this->indexAction($_locale, $branch, $page);
}

a closing quote is missing on `testval` (third row). I cannot edit it on your behalf because an edit needs 6 chars — Bertuz, May 08 '16 at 00:39

This is the correct way of setting cookie. To read cookie already written in the browser do:

$request->cookies->get('myCookie');

But after I created cookie in the $response object:

$cookie = new Cookie('myCookie', 'contentOfMyCookie');
$response = new Response();
$response->headers->setCookie($cookie);

I call this method:

$response->headers->getCookies();

I get an array of cookies, which are to be written in the browser - not those already existing there.

Figuratively, between $request and $response there is a time of executing controller's code.

Besides, in a twig template you can use

{{ app.request.cookies.get('myCookie') }}

you thus get value of the cookie already written in the browser, not that from the $response object! Newly created cookie from the browser you can read only after having reloaded page (ajax doesn't need to reload whole page).

To sum it up, you can read cookies using $request object, and create them with $response object. (Obviously, for some reasons, you can also read $response object cookies - but these are rather rare situations).

$response->headers->getCookies();

should return an array of cookies look in ResponseHeaderBag class for more information about that function

This method returns a empty array. – Ben Oct 11 '11 at 14:25
Well, but I want to check the cookie values as soon as I request the main page, any idea? – Ben Oct 11 '11 at 14:50

i think you are mixing the response with the request, at that point you have an empty response. Try `$request = $this->getRequest(); $request->cookies->all();` – Miguelo Oct 11 '11 at 14:54

In the most of cases it is not the right way of working with cookies. Look at my post below – Błażej Kocik May 07 '13 at 09:14

Example how to use Cookies and Session:

<?php

namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpFoundation\Response;

class DefaultController extends Controller
{
    public function indexAction()
    {
        // Set session value
        $session = $this->getRequest()->getSession();
        $session->set('test', 1);

        // Get session value
        $value = $session->get('test');

        // Set cookie value
        $response = new Response();
        $cookie = new Cookie('test', 1, time()+3600);
        $response->headers->setCookie($cookie);

        // Get cookie value
        $this->getRequest()->cookies->get('test');
    }
}

            use Symfony\Component\HttpFoundation\Cookie;
            use Symfony\Component\HttpFoundation\Response;

            // set current active tab in cookie 
            $cookie = new Cookie('myProfileActiveTab', 'myaddress', strtotime('now + 60 minutes'));
            $response = new Response();
            $response->headers->setCookie($cookie);
            $response->send();


           // get current active tab from cookies
           $cookies = $request->cookies;
           if ($cookies->has('myProfileActiveTab')) {
               $activetab = $cookies->get('myProfileActiveTab');
           }
