Its already there at registration.

so what you are saying is to record users IP when logging in and keep a record of like the last 5 IP`s used to login
right ?

the benefit, is when you are watching an ip that's suspicious (let's say the owner of a rival dating site ;-)
, and he logs in at a different account, you can see the history?

I kind of agree with fatlizard but then again maybe I don't get the point. If you have competitors logging in to your site and joining, how does that benefit your competitor unless they are trying to steal members.  As far as IP goes, any competitor worth their salt knows their way around that, if they don't, I wouldn't consider them much of a competitor but more like a desperate or inept webmaster trying to find solutions in all the wrong places.

p.s. not sure who your host is, but most server logs will tell you that info as well.

Another consideration is that many Ips are not static. My internet service provider like most has a big range of IP numbers. When I log into a website at 9am, the IP number is different to that when I log in at 3pm. Many websites also do not have static IPs. Checking IPs is useful for checking that someone who claims to be in the US but might actually be in the Congo, but not very useful for much else.

I tried this in the includes/lib/account_login.php file, but it didn't work.
Can anybody give me a clue where to post this function?

// IP logger
// ----------------------------------------------

$id = isset($_GET['id'])   ? trim($_GET['id'])   : 0; // member id
$dt = new DateTime();

// define log file, set to chmod 777
$file = "iplog.txt";
// get ip address
$addr = $_SERVER['REMOTE_ADDR'];
// open file and append
$openfile = fopen($file, "a");
// write IP-address
fputs($openfile, "$dt,$id,$addr<br>\n");
fclose($openfile);

Hi, try to put it at index.php or at /includes/lib.php

try with username instead of id

$id = $SESSION->conf['username'];
$dt = new DateTime();
