Question by JDickens10: How can I control who answers my online-created surveys?
For medical research purposes I’m trying to create an online survey for the assessment of hypertension and daily dietary habits. However, I’ll need to make sure that, if a person has already answered my survey, he or she won’t be able to answer it again. Where can I find a site or download software in order to make sure that no surveys are answered with the same IP address/cookies?

Best answer:

Answer by just “JR”
??? You are capable of coding an on-line survey, and get answers, but you can’t “prevent” a given IP to answer twice???
- When the user logs-in for the first time, get their IP, store it into the
tag AND set-up a cookie on the machine.
- When the form is posted, store that IP in your database.
- When another user comes in, read the IP, and check against the database
(In Php, use $ _SERVER['REMOTE_ADDR'] to get the IP. That will be “dotted form” xxx.xxx.xxx.xxx style. Use ip2long() to get its “long” numeric value.)
