Question

I am currently creating a website that allows anonymous users to input data (or comments) into a database and allows other anonymous users to the site to vote up or down the comments presented on the site.

I have already created the functionality to allow a user to create a comment and allow another user to vote on the comment. The problem I’m having though is thinking how I can limit each visitor to the site to only vote on each comment once.

My idea was to create a session ID when the user votes and then when they try and vote again to try and compare if a session ID already exists. This would work but only until the session is destroyed. Does anyone have any other ideas of how this could be achieved?

I am assuming I might be able to use some of the $_SERVER options available

Thanks in advance

Answer 1

Just restrict the voting with IP’s or either Cookies, i also created 3 websites in which i had to take the public voting, earlier i did it with IP’s but then i changed back to cookies, i also saved IP’s along with setting cookies to check if the users are deleting cookies again and again to vote, but i never had such problem, so my opinion in just go with cookies, because not everyone can find that we are doing it with cookies.
