Sharing non-WHMCS validatelogin session on WHMCS pages.

[kpedana]

Hey guys, I have a page "sub.domain.com", that uses the API to validatelogin and start the session. I'm not actually doing any session_start or anything, I'm calling validatelogin, and then on my non-WHMCS pages I'm just using:

 

define("CLIENTAREA", true);

require("/www/domain.com/html/billing/init.php");

use WHMCS\Database\Capsule;

$ca = new WHMCS_ClientArea();

$ca->initPage();

 

And everything seems to work great staying logged in on the non-WHMCS page. What I'm trying to do is when someone visits domain.com/billing it knows there's that session started already, which doesn't seem to be the case. Now, if I do put everything on the same domain it seems to work swimmingly. My php.ini has the cookie_domain as .domain.com so I'm unsure if it's cookie related -vs- something code-wise. Any help would be greatly appreciated.
