Contact Form Spam

Expand Post »

I have a website that I just created a contact form for. However. it seems like a bot has hit the form, and continously fills out emails. I don't know php very well - and someone else did most of the work.

I don't want to put a captcha in, as it reduces the amount of people that will fill out the form. Instead, I'd like to make a "do or die" code that requires the user to fill out a phone number.

Here's the current code. What should I do to fix it?

<?php

$ip = $_POST['ip'];
$httpref = $_POST['httpref'];
$httpagent = $_POST['httpagent'];
$visitormail = $_POST['email'];
$comments = $_POST['comments'];
$case_description = $_POST['case_description'];
$phone = $_POST['phone'];
$street = $_POST['address'];
$yourname = $_POST['name'];

$todayis = date("l, F j, Y, g:i a") ;

$subject = $attn;

$notes = stripcslashes($notes);

$message = " $todayis [EST] \n

";

$from = "From: $visitormail\r\n";

mail("jcernamonroe@yahoo.com", "Contact Info from Exclusively Criminal Deffense", $message, $from);

?>

Re: Contact Form Spam

The phone number is a good idea as a spam bot probably won't fill that in correct, especially if we validate it.

This method will accept a 10 digit phone number with spaces, dashes, or neither.
