Hello: I am a long-time htmler butsomething has really gotten past me. When I registered here, the question was asked, which is smaller a cow or an ant. The only word that would verify me is "ant."

It is this kind of excluder that I need on my forms. BUT I DON'T KNOW WHAT THIS IS CALLED AND I HAVENT BEEN ABLE TO FIND ANY INFO ON IT.

I need to keep those machines out of my forms.

Can you please point me to a simple script that will help me accomplish this?

Thank you!

This type of thing, to distinguish from spam robots and human users, is usually called a CAPTCHA. (http://en.wikipedia.org/wiki/Captcha) Often they are a randomized picture of letters (somehow skewed so that the bot wouldn't be able to recognize them) that the user has to input. A quick google brings up some good tutorials, and actually there was a CAPTCHA script posted just recently in the PHP snippets category: http://www.codingforums.com/showthread.php?t=131066.
