I would like to check whether a Cookie exists, and if so, get the value. But it looks like Drupal is blind to external cookies that have not been set inside Drupal.

$mycookie = \Drupal::request()->cookies->all();

Returns an array with only the Drupal cookies, and I can see in my web browser that there are more (some that I am interested in and I can't modify he app that is creating those cookies). I remember there was a similar issue with Symfony 2 and session but I can't find it...

  • Are the cookies of the same origin?

  • @mradcliffe They are created in a different host than the one I have Drupal running, (they are actually Mautic cookies and I'm trying to to do that "mautic.org/community/index.php/2985-get-data-from-mautic/0" - oh wow now I realize I might have asked in the wrong place or wrong question...) Is it possible to get those cookies?

    I'm voting to close this question as off-topic because this is nothing Drupal-specific. You can always only access cookies from the same origin. You can't access cookies from other origins. Imagine if that were possible. I could then write a web application that would harvest your gmail cookies, and log into your gmail remotely to do whatever I like.

1 Answer 1


For external cookies please try with $_COOKIE['cookie_name'].

if (isset($_COOKIE['cookie_name'])) {

The code will print out the value of the cookie if present.

For a more specific answer please explain your question.Ty!

    Please see the first sentence:"I would like to check whether a Cookie exists, and if so, get the value." The: $_COOKIE['cookie_name'] will return the value if exits. Also there is no clear question here, and no question mark. It is very easy to put -1. Sep 14, 2016 at 14:53
  • I think that you need to improve your question, maybe with an explanation about why this is the good solution Sep 14, 2016 at 14:55
  • I not the downvoter but I'm sure that the downvote was because this site is for learning, and you need to explain a little your answer. Sep 14, 2016 at 14:56
  • My opinion is that you should encourage good responses not take away people's binge. Sep 14, 2016 at 14:57
