Zimmertech Comment Form Tutorial with reCAPTCHA Support
Brian Zimmer at zimmertech.com posted a nice PHP tutorial on creating a modular Comment Form, similar to what you might see on a blog. The tutorial was brought to our attention at Spectrum Nashville when someone wanted to use this module but add support for anti-spam filtering with the reCAPTCHA library. We downloaded the Zimmertech tutorial and added reCAPTCHA support into it, then posted it here to share as a solution for anyone who has a similar requirement. Mr. Zimmer has since provided a link to us from his original tutorial, as well.
We highly recommend that you read the original Zimmertech tutorial first (click here to see the tutorial) so that you understand the core functionality addressed by Mr. Zimmer's work. Once you understand the process and the basic code to support it, return here to get the edits for supporting reCAPTCHA.
