The first is $_POST['user_captcha_input'] should be $_POST['captcha_input'] to match the form field. The second is with case. If you enter the letters in lowercase you will get an error. Simply change if($_SESSION['encoded_captcha'] == md5($user_captcha_input)) to if($_SESSION['encoded_captcha'] == md5(strtoupper($user_captcha_input))) There are two errors in this script.

I can get it to give an error no matter what is entered. Guess I'll keep looking. I think there is confusion over where to place the code in the form.

When I would click on submit and the everything was good it would not post to the database. I also used some error checking for required fields. I finally gave up and put a math test in place. Maybe I did it wrong. I tried to use Captcha for my guestbook but I coul never get it to post. When I would click on submit and the everything was good it would not post to the database.

This submission landing page is where the error is displayed. You can do a little fancy work and submit the form to itself, and if there is an error, show the same submission form with an error message, or display something else entirely if there isn't an error.
