Question: I'm trying to access cookies I set in my Drupal website.
I created two cookies on a form submission :

* with the Drupal funtion = `user_cookie_save(['myfirstcookie' => 'myfirstdata'])`
* with the classic PHP function = `setcookie('mysecondcookie', 'myseconddata', time() + (86400 * 30), "/")`

My cookies are set, no problem.
But, I didn't find how to get them (or one of them) from my Twig templates. The app.request.cookies of Symfony seems to not exist.

Do you have any idea ?

Answer: 
`Twig` has the global `app` helper context, via which you can access the cookies (among other things). Try this:

```
{{ dump(app.request.cookies) }}

```

And ultimately:

```
{{ app.request.cookies.get('MY_COOKIE_NAME') }}

```

Remember, `cookies` is an instance of `ParameterBag` ([API](http://api.symfony.com/3.1/Symfony/Component/HttpFoundation/ParameterBag.html)), so you have to access it via `get()` call.

Hope this helps...
Past Cookie variable from the controller and check it. It works to me.
My code in controller is:

```
$data['cookie'] = $_COOKIE['postcode'];

```

postcode is my cookie name and in my twig templete, i write this line of code 

```
{{  cookie  }}

```

and show my cookie value. Thanks.
