@pyroAug 17.2003 — in PHP:

untested code
[code=php]<?PHP
if ($_SERVER["REMOTE_ADDR"] == 000.000.000.000) {
header ("Location:http://www.yourdomain.com/banned.php");
}
?>[/code]That code must go at the very top of your page, before any content is printed.

@JonathanauthorAug 17.2003 — If I add more do I do this?

[code=php]
<?PHP
if ($_SERVER["REMOTE_ADDR"] == 000.000.000.000 || $_SERVER["REMOTE_ADDR"]== 000.000.000.001) {
header ("Location:http://www.yourdomain.com/banned.php");
}
?>
[/code]

And thanks for that speedy reply!

@pyroAug 17.2003 — Yep, looks good (except for the header, which I know is from the forums...)

@JonathanauthorAug 17.2003 — It has to be on the same line right?
Copy linkTweet thisAlerts:
@pyroAug 17.2003 — The if statement? Yes...
Copy linkTweet thisAlerts:
@JonathanauthorAug 17.2003 — Is this okay?

[code=php]
<?PHP
if ($_SERVER["REMOTE_ADDR"] == 222.222.222.222) {
header ("Location:banned.html");
}
?>

@pyroAug 17.2003 — I just thought of something. You'd better enclose the IP's you are banning in quotes. Also, for the header, you can use a relative path, but you are supposed to use an absolute path.

@PeOfEoAug 17.2003 — IP addresses change though. So you might ant to ban a range of ip addresses to keep them out for good.

@JonathanauthorAug 17.2003 — how do you bann a range of ip addresses?>

@PeOfEoAug 17.2003 — I dont know what it would look like in php but it would be something like

if remoteaddr < someip and > someip then redirect. It would just be a simple if statment with less than and greater then in it.

@pyroAug 17.2003 — To take all IPs from 000.000.000.000 to 000.000.000.999 use [code=php]if ($ip >= "000.000.000.000" && $ip <= "000.000.000.999")[/code] Note that by banning an IP block, you will potentially ban a large number of users...
Copy linkTweet thisAlerts:
@PeOfEoAug 17.2003 — But by not banning a block the user simply has to reconnect on another ip to come back. The best solution would be a timed system where an ip block is banned for several hours then is lifted, but it would require a data base that sotres the ip and I am guessing some xml or a system that logs the time then on page load it can be checked and unbanned by another user. But it would be very very complicated and involve xml with a server sid elanguage most likely.

@Robert_WellockAug 18.2003 — It may have been easier to use .htaccess to ban the IP numbers.

@Daot_LagorilleAug 18.2003 — As all my "rap artist" friends say:

"This shit is [i]tight[/i]!"

Nice bit o' the ol' "php" code there.
