That's why using your server-side script is the only way to go. @stan: as I mentioned to Peter as well, using javascript won’t do anything if a spider is filling out the form.

Obviously if someone really wanted to, they could write a custom script for your site... but it's rare. If you are a larger site, I would recommend using reCaptcha or something similar in addition to this. @peter: the only thing to remember with your solution, is spammer spiders don’t read javascript… so doing it with javascript wouldn’t make a difference.

The only way around this is to randomize the honeypot field and use some javascript to calculate which field it actually is and then hide that, but this incurs an additional dependence on javascript while also staying theoretically defeatable given enough effort to defeat it and widespread adoption of it to make the effort worthwhile. I would just use a reCaptcha, they make it pretty easy. This works until any spammer decides to write some simple code to detect which is the honeypot field.

Can some one help with that. Do you have the form action call both scripts on submit? Not sure how to implement this.

I just finished implementing it on all my forms. Another good trick to mention: As tempting as it is to rub your spammer's face in the fact that you caught them, it's MUCH better to simply act like they tricked you and NOT output any special message when you catch them. Just act like you sent the form when you didn't. If you tell them it didn't work, they'll just try harder to get through. Let them think they're done. This is a cool technique.
