im using php to submit data from an online form to an email address.theres code at the start which is meant to stop spammers sending stuff but one guy keeps sending multiple emails to the address using the form. you cant even link to the page with the form at the momment so how hes doin it i dont know.is there any better code to put a stop to this loser?

this is what iv got justnow



<?
function checkOK($field)
{
if (eregi("\r",$field) || eregi("\n",$field)){
die("Invalid Input!");
}
}

$name=$_POST['name'];
checkOK($name);
$email=$_POST['email'];
checkOK($email);
$comments=$_POST['comments'];
checkOK($comments);

Why do you think this won't let him send emails to you?

I think you need to add some kind of captcha script to your form. You should have seen it, the picture with curved letters or digits that can only be read by human.
