I just created an online suvrey form using PHP and MySQL, which is working just great. In fact, I got a lot of great from geniuses in this site.
I have a little problem: The problem is that people may submit the form as many as they want, which is certainly not what I want.
I would like to add some scripts to keep a person from submitting not more than once.
I searched an answer to a similar questions, but, for some reason, I couldn't find one.
Hope you geniuses may kindly help me again!
