Need help with reCAPTCHA. Never installed it before. When Submit is clicked the "quoterequest-redirect.php" is run but I think it would be better to test the reCAPTCHA before the "quoterequest-redirect.php" program has been run. I check the CAPTCHA in "quoterequest-redirect.php", it displays a invalid message if invalid but the user has to tab back to fill in the CAPTCHA again. The reCAPTCHA show correctly but I need some help/hints/tips here.

Ernie : There's nothing complicated here. You don't need to get public and private keys or other such complications. A CAPTCHA is as simple as: What is 2 + 2? What is the color of an orange? Answer correctly and you pass. If not, then you don't. The purpose of a CAPTCHA is simply to keep bots out and allow humans to pass. If you base your CAPTCHA on a strange graphic, then you keep visually impaired users out. That's not good. Here's an assortment of CAPTCHA's, but I think the Question CAPTCHA is the best. http://webbytedd.com/aa/assorted-captcha/ Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com

Yes, but I assumed he meant reCAPTCA, not simply CAPTCHA. The former is a specific implementation of the latter. http://recaptcha.net/ Andrew

Andrew: Yes, I realize that. But what I said about the technique stopping the visually impaired is equally true. If you care nothing about those types of folks, then proceed (by the Grace of God) along your sighted way. Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
