Stefany93 Posted August 21, 2012 Share Posted August 21, 2012 Hello friends, I have recently written a rating system, howerver I want to restrict a user to rate a post multiple times. I tried storing the their IP in the DB but the problem arose when I found out that they could only vote on one post for the entire blog and that wasn't pretty. So could you please tell me a better way to create a state for the user to vote only one time per a post? Thank you very much! Best Regards Stefany Quote Link to comment Share on other sites More sharing options...

Stefany93 Posted August 21, 2012 Author Share Posted August 21, 2012 Thanks but aren't sessions destroyed once the user has closed their browser, so that makes sessions securing the double rating useless? Quote Link to comment Share on other sites More sharing options...
suresh_kamrushi Posted August 21, 2012 Share Posted August 21, 2012 You can trace it with IP address. Quote Link to comment Share on other sites More sharing options...
Christian F. Posted August 21, 2012 Share Posted August 21, 2012 Save the identifier you've selected, along with the ID to the post/poll. Then check both, to see if the user has access to vote or not. Quote Link to comment Share on other sites More sharing options...
Stefany93 Posted August 21, 2012 Author Share Posted August 21, 2012 Awesome, I stored the IP in the DB using the post id and it worked! How terrific are you guys? Thank you so much! Quote Link to comment Share on other sites More sharing options...
ialsoagree Posted August 21, 2012 Share Posted August 21, 2012 Awesome, I stored the IP in the DB using the post id and it worked! How terrific are you guys? Thank you so much! Erm, wouldn't it be better to store the user's ID in the DB, or are you not talking about registered users? My only concern is that, if a logged in user rates something, then comes back on a different computer, from their own perspective their rating is now gone and they can rate the item again (in reality, they've just rated the same item twice from 2 different IP's). Not to mention, if two people share a computer or an IP address, 1 of them will lose the ability to rate if the other one rates that item.

darkfreaks Posted August 21, 2012 Share Posted August 21, 2012 yeah i think this would be a better idea like mentioned if in the vote table there was a "has voted" column with int 0 or 1 that way if session in the DB is set to one they have voted even if the session is no longer registered. and would still come out to "user has already voted" get the idea?

Mahngiel Posted August 21, 2012 Share Posted August 21, 2012 what you're doing will hurt you if you plan on having more than one poll. Quote Link to comment Share on other sites More sharing options...
Stefany93 Posted August 23, 2012 Author Share Posted August 23, 2012 Thank you guys, the way I am doing is that when they vote on an article I first get the user's ip address and store it in a table inside a DB with the article's id. That way they couldn't not vote again on the same article, but they will still be able to vote on other articles. Actually this is what you guys told me to do, so I did it and it worked!
