Does anyone know any good contact form codes which will be spam free as I keep getting spam and is getting very annoying

well no contact form will be spam proof, well to a certain extent, i would say your best bet is to use something like re-captcha umm other than that i dont know, if it is a bot, the bots arnt programmed to read the codes so that should stop most of the spam, but unless theres a sad loner that sits there typing out lol.... you can implement re-captcha on any fourm php ect and you can find a good tutorial on how to make contact forms on www.tutorialized.com, make your own so you actually learn something about what your doing, and it will make future projects ect also easier.

Read this topic

 

May well be of use to you

And indeed the recent topic on Anti Spam / Captcha might also be helpful.

Thanks for the replys very helpful. One day I will have the coding skill to beat these bots

I just block the IP's

I block the IP addresses in my.htaccess file.

You could also try adding a hidden field that isn't visible to the general user, but spam bots will see it and fill it in. Your validator then checks if the field is full or empty and acts accordingly. I implemented this type of thing on a client's contact form and it worked a treat.

Your best bet is to try setting up reCAPTCHA. Best free anti-spam I've come across.

Use a regexp to check for http:// and www. usually works well too. Pretty much all my contact forms block these and I've not been spammed yet.

I use php for mx lookup which ensures a real domain, + a pritty good sendmail config removes the rest.

 

If you want to totaly remove bots from a php mail form, the re-captcha is extremely easy to setup, I use this on user registration forms.

 

http://www.captcha.net/

 

they also have one specificaly for email:

 

http://mailhide.recaptcha.net/

I did this on my portfolio site a few months ago and the amount of form spam i get has dropped dramatically, in fact i cant remember the last one i got. i think it is defiantly a better option than using a captcha, as a lot of people dont like filling them in

 

i also have an mxlookup to ensure the email address is valid, but that isnt too reliable, because as soon as a bot uses an aol.com,yahoo.co.uk,gmail, etc it gets let through.

Hi I am really interested in using this technique as the captcha says it is not supported :s How would I use this method if my input boxes are:

 

$firstnameField

$lastnameField

$address1Field

$address2Field

 

cannot find much on this in google...

You could try using the code below. It will check all items in the $_POST array for "<a" and "http:" and also common mail hijack attempts by blocking "bcc:" "cc:" etc

 

if (preg_match_all("/<a|http:/i", implode($_POST), $out)) {	 // check for <a and http:
echo "Found some spam";
}

if (preg_match( "/bcc:|cc:|multipart|url|Content-Type:/i", implode($_POST))) {  // check for spam indicators
echo "Found some spam";
}

 

Hey I have added this code to my php process. I get the message saying spam found but it still sends the e-mail

 

here is the page I am trying to secure the form for

here is my php code also

<?php
/* Variables */

$emailSubject = 'Website Message!!';
$webMaster = 'howlomogo@hotmail.com';




	/*check for spam */

if (preg_match_all("/<a|http:/i", implode($_POST), $out)) {	 // check for <a and http:
echo "Found some spam";
}

if (preg_match( "/bcc:|cc:|multipart|url|Content-Type:/i", implode($_POST))) {  // check for spam indicators
echo "Found some spam";
}

/* Gathering dta variables */

$firstnameField = $_POST['firstname'];
$lastnameField = $_POST['lastname'];
$address1Field = $_POST['address1'];
$address2Field = $_POST['address2'];
$countyField = $_POST['county'];
$postcodeField = $_POST['postcode'];
$telephoneField = $_POST['telephone'];
$mobileField = $_POST['mobile'];
$emailField = $_POST['email'];
$maxrentField = $_POST['maxrent'];
$descField = $_POST['desc'];
$desc1Field = $_POST['desc1'];




/* this EOP is what will be displayed in the email */

$body = <<<EOD
