Hey guys, Ive got a site and have a form used for feedback and requests and have started to get a lot of junk bot submits from it. What is the best way to secure this so the junk mail will stop? I know a lot of sites use the number and letter picture that you have to type in but have no idea how to do this. Is this the best way or is there other easier ways? Any info id really appreciate it. Thanks Jim D.
Honestly, I've never done this before....you could write a Perl script and use ImageMagik or something to generate these images...or you could use a service like: http://recaptcha.net/whyrecaptcha.html. I also found a way to do it in PHP: http://www.codewalkers.com/c/a/Miscellaneous/Creating-a-CAPTCHA-with-PHP/ Again, I've never attempted to do this before, but good luck. If you get something figured out, please post what you did. Happy Coding!!!
