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
