User Banning

[catacon]

I'm not sure if this is allowed, so if it isn't please delete it.

I am starting a site up and thought that from time to time, a user might get out of hand and need to be banned (I'm a poet and I don't even know it), as they do here. I found this script:

PHP Code:

0
<?php
1
$banned_ip = array();
2
$banned_ip[] = '111.111.111.111';
3
$banned_ip[] = '111.111.111.112';
4
$banned_ip[] = '111.111.111.113';
5
$banned_ip[] = '111.111.111.114';
6

7
foreach($banned_ip as $banned) {
8
    $ip = $_SERVER['REMOTE_ADDR'];
9
    if($ip == $banned){
10
        echo "You have been banned!";
11
        exit();
12
    }
13
}
14
// rest of PHP Script here!
15
?>

You have to enter the users IP address to ban them. How do I find out what their IP address is so I can ban them?

This is all legit, I just want to have a clean site. I am not trying to do any bad from this.

Thanks

Usually when they post you can find their ip address from what it leaves. I can't remember how I used to do it, but when I made a forum with a few friends it used to automatically add their ip address to the bottom of the message, so that even though people could change their names we could tell who was posting by the ip

Do you want hem banned from the entire site? Or just a discussion forum.

If it's a discussion forum then running something like phpBB or vBulletin has a feature to enable you to do that.

Entering their IP address does not work well. IP addresses change every time on dialup and periodically on broadband. Also wouldn't prevent them from using another connection. Most of the forums allow you to ban a user or a range of IP addresses. Occasionally you will ban a user and he will register under a different name. Then your options are to ban by IP addresses and/or turn off registration.

OK. Is there any way to have a column in the database called banned or something and then if they try to login, it will not let them due to that?

Sure. You could make it a Enum field (0,1) and default it to 0. 1 would indicate a banned user.

Ok, thanks. That's easy!
