The best overall solution for you is to use cookies to store each vote per category, then tally the votes on the last page. You will need code to determine whether the particular category has been voted on based on if the client's cookie is currently holding the information for that category. Unfortunately, if the client clears the cookies in his/her browser, they will be able to come back again to vote. Unless you plan on creating a login script to go along with this voting system, there is no other solid way to eliminate multiple votes.
