cookies on domain and subdomain

Desbrina

I have a cookie that is set on my domain which works fine for the domain, but i want the subdomain to be able to access it, but it doesn't seem to be working

php.net says to set the domain as '.example.com'
I've tried that in my code but the subdomain still can't use it

      setcookie("dwtcg[u]", $_POST['username'], $expire, '/', '.darknesswithin.com.ru');
      setcookie("dwtcg[i]", $row['ID'], $expire, '/', '.darknesswithin.com.ru');

You won't be able to access the SAME cookie that was set on, www.domain.com and domain.com, due to security reasons in place in almost all browsers.

Apparently not...

On the contrary - you can certainly set cookies across all subdomains.

In fact, I can't see any reason why the above code snippet shouldn't work... is there any chance you can show us an example of this script live? If you like, you can PM me a test username/pw and I can see what the cookies being set look like.

Well well, I sure do look a fool 😃

Can you propogate a session over a subdomain change?

Yep, just like you would a cookie (since that's what the session ID is normally stored in - nothing more than a cookie) using [man]session_set_cookie_params/man.
