IP ban script

[alexandom]

I have a simple php code that I received from my hosting that allows me to capture information from people who visit my site.

I am now facing a problem with someone overloading my form.txt that is attached to my form.php with thousands of emails and I need to stop them. My hosting tells me that I need to look for an IP ban script. Any advise???????????

Thanks

you can create your own fairly simply. there should be many tutorials around the internet.

IP banning is pretty unreliable. People can change their IP addresses, then just come right back and start populating your text file again.

 

Are people supposed to be able to write to your text file? If not...set it to read only, then they can't put anything in it. Maybe start storing the info in the text file in a database instead?

Chances are, the person is using a script of some form to do it, so a CAPTCHA might stop them (Google it) along with anyone else you might have future issues with.

 

As for the IP thing, the viewer's IP is stored in $_SERVER['REMOTE_ADDR'], so you could do something like:

 

$banned = array('xxx.xxx.xxx.xxx');
if(in_array($_SERVER['REMOTE_ADDR'], $banned)) {
echo 'You\'re banned!';
exit;
}

 

Edit: fixed the syntax error.  Thanks ProjectFear ;p

be clever here dont do it with ip ban do it by email address and a ip cheek via email.

except you wouldnt have errors in your code like corbin. lol. that would result in an error because you didnt escape your ' in the echo. lol.

Ehhh, I'm allowed to make mistakes too!

 

I originally had "s, but I changed it to 's because I've been trying to get in the habbit of using single quotes when variables aren't involved.... I'm OCD ;p.
