I'm getting an error in my error_log:

PHP Notice: Undefined variable: ip in /srv/www/htdocs/forum/bb_functions.php on line 128


Here is where it comes from in bb_functions.php. Is it because it can't get an ip for some reason from the host?

function getIP(){
$ip1=getenv('REMOTE_ADDR');$ip2=getenv('HTTP_X_FORWARDED_FOR');
if($ip2!='' and preg_match("/^[0-9.]+$/", $ip) and ip2long($ip2)!=-1) $finalIP=$ip2; else $finalIP=$ip1;
$finalIP=substr($finalIP,0,15);
return $finalIP;
}

Please upgrade this function from the version what we have now in Downloads. We know about this bug and have fixed it recently.

The function should list:

function getIP(){
$ip1=$_SERVER['REMOTE_ADDR'];
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) $ip2=$_SERVER['HTTP_X_FORWARDED_FOR']; else $ip2='';
if($ip2!='' and preg_match("/^[0-9.]+$/", $ip2) and ip2long($ip2)!=-1) $finalIP=$ip2; else $finalIP=$ip1;
$finalIP=substr($finalIP,0,15);
return $finalIP;
}
