Variables available to Captive Portal HTML/PHP

[Lectrician]

IS there a list of variables available for use in the captive portal HTML / PHP custom page?

I would like to have the users local IP address and MAC address available to me.  Is this possible at all?

Thanks.

$CLIENT_MAC$ and $CLIENT_IP$

The list of vars can be looked at portal_reply_page() on CP source.
