Checking IP's against spammer database
There is a good free RBL that checks users against a database of known forum spammers. You can check a users IP against it before allowing them to do anything on your site. Here is some example PHP code:
Code:
function blacklisted($ip) { $dnsbl_check=array("dnsbl.tornevall.org"); if($ip){ $rip=implode('.',array_reverse(explode(".",$ip))); foreach($dnsbl_check as $val){ if(checkdnsrr($rip.'.'.$val.'.','A')) return $rip.'.'.$val; } } return false; } Enjoy! |

OK maybe I am not understanding how this works
the above code which starts with function blacklisted I thought that the code would check with the SPAM IP site? so I was wondering where the code would be placed my apologies in advance if I have the wrong end of the stick Thanks G |

If you have some PHP code, and you want to check to see if an IP address is of a known spammer, put the function in the first post of this thread into your PHP script. WHERE exactly I cannot tell you as that is different in every script.
Then you just pass the IP to the function and it will tell you true or false: Code:
if (blacklisted('123.123.111.123')) { ## This IP is blacklisted! } |
