Free Turing/Captcha Image Script

Friday, 9. February 2007, 02:50:30

, , , ...

Ever wanted to protect a form (such as a contact form) on your site to prevent spam bots from using your mail server to send out mass emails to hundreds...no thouands...hundreds of thousands of users?

I have the perfect solution for you. The Tribulant turing image script uses PHP GD to generate an image with random characters on it which needs to be typed in by the user in order to successfully submit a specific form on your site.

Tribulant Turing Image Script

Give it a shot.
Unfortunately...as I type this, the documentation for this script isn't done yet. It will be done and ready very soon, though the implementation is very simple.

The backend creates a new $_SESSION variable named $_SESSION['code']. You can compare this variable with the user's imput to ensure that the code which the user has typed is correct. You'll need to convert the user's string to lowercase after encrypting it with md5(); hash PHP function.

Please feel free to post your questions and comments here.
All ideas, queries and requests will be appreciated if it could help me to improve the script.

Enjoy, and have fun! :wink:
