I need to save a cookie for anonymous users in Drupal 8 when users visit the site for the first time, which will be used to display a message.

I can successfully save one using setcookie("FirstTimer", 1, strtotime('+1 year')); but I am sure Drupal 8 should have some alternatives.

I can also use the following code.

$user_is_first_timer = !isset($_COOKIE["Drupal_visitor_FirstTimer"]);

When I open it in Google Chrome, this works, but when I open it in incognito or in Firefox, there is no message. Somehow cached pages are being served.

The code is used in an implementation of hook_page_attachments().

As with Drupal 7, you use user_cookie_save(). In Drupal 8, there is just a method in a core class using that function: SystemController::compactPage().

Notice that the function accepts an array of values; each value will get its own cookie. Also, the function prepend Drupal.visitor. to the name of the value to make the cookie name; so, user_cookie_save(['myCookie' => 10]) will create a Drupal.visitor.myCookie cookie.

  • This saves the cookie, but somehow it doesn't depend on the browser!!.. Like I checked in chrome, the cookie is not set and the message is displayed, on refresh it's not; well and good. Now when I open it in Firefox I should get the message. But I don't. When I clear the cache the message shows up – Malabya Tewari May 26 '16 at 7:25
  • Cookies do depend from the browsers. If the second browser is not importing data from the first, it should not have any cookie. I cannot reproduce what you are saying in my test site. – kiamlaluno May 26 '16 at 7:32
  • Does Drupal core cache the cookies as well? drupal.org/developing/api/8/cache/contexts – Malabya Tewari May 26 '16 at 7:46
  • I don't think, or SystemController::compactPage() should disable the cache. – kiamlaluno May 26 '16 at 7:49
  • Is the cookies working for you? Can you somehow share your code? Here is what I am trying to do pastebin.com/AFg2xLWc The code in a Event Subscriber which is triggered for all page requests. More like hook_init in Drupal 7. – Malabya Tewari May 26 '16 at 9:49
