Display client MAC on captive portal login page.

FlashEngineer

So maybe this is more of HTML/PHP thing, but I see the /usr/local/captiveportal/login.php has $clientmac… I uploaded my own html page in the captive portal for the login page. Now how do I access this variable in my html page to display it?

Lots of php in the default login page to look at. Should be trivial if you know the name of the variable you want.

I'm not sure how or what to do? I never really did HTML or php… How do I link the php functions in my HTML file?

on your captive portal form you can use the macaddress through this codes:

$arp=`arp $ipaddress`; #run the external command, break output into lines
$lines = explode(" ", $arp);
$macaddr = $lines[3]; #Actual code
