Enable Login only from specific IP Addresses

Hi,
Is there a way to only enable phprunner login only for users from a list of specific ip addresses.
I would like to prevent login from locations other than the office.
Thanks,
JP.

If the IP address is fixed you could check the users IP from session variable (see PHPR help) and create a simple IF statement in user login event to check if IP is valid..something like...

$ip=$_SERVER['REMOTE_ADDR'];

if $ip = "192.168.1.1" {

echo "ok";

}


If more than one or two IP's probably best way is to create a database table with valid IP ranges:
ID | StartIP | EndIP |

+-----+-----------------+-----------------+

| 1 | 123.123.123.123 | 123.123.200.200 |

| 2 | 124.129.0.123 | 124.129.200.200 |

| 3 | 231.160.124.1 | 231.255.255.255 |
and then create code in user login event to check if IP exists in table something like:

function check_ip($IP)

{

$IP = ip2long($IP);

$result = mysql_query("SELECT * FROM IPRangeTable");

while($row = mysql_fetch_array($result))

{

$StartIP = ip2long($row['StartIP']);

$EndIP = ip2long($row['EndIP']);

if ($IP >= $StartIP && $IP <= $EndIP)

{

return FALSE;

break;

}

}

return TRUE;

}


A rough example but hope it helps..
