Need Login Status in Other Subdomain Page

[mgilang]

Hi all,

i build custom order form so user will be using this order form instead the default whmcs.

let call this page : order.domain.com
whmcs installation in : whmcs.domain.com

order.domain.com and whmcs.domain.com in the same server

in order.domain.com i need user to choose whether they want to new registration or login with their current account.

how to achive this? i have try to get user session from order.domain.com with no luck.

i try using AutoAuth (https://docs.whmcs.com/AutoAuth) but it must be redirect to whmcs area (right?)

Thanks
