I'm planning to create a voting page, where users can vote on different ideas or suggestions. I think for my situation it will be best to use a Thumbs Up / Thumbs Down type voting system. Can anyone explain how these work? Do they use division, average, etc?

Thanks

Its ok the logic about the post, and his rating up with by 1, but i want to understand how to mark that one user is like the current post. If there no check about this, one user can use Tump UP more than 1 time. This is what i want to know, how to remember that user A is vote alrady for post B.

you can have one table for storing user_id and post_id.
When user vote any post there will be entry in that table and if there is any entry vote up-down arrow will not be shown for that post.

Do you have a system for users to login. That way you can make sure that only one user can vote once for a post, just like what vibhadevit says.In addition to the user_id and post_id, also put in the +1 or -1 which you can then use to calculate the rating.

Once you get that then either use (number of thumbs up - number of thumbs down) as a rating method or divide that number by the total of users voted and then multiply by 10 to get the rating on a 1-10 rating scale.

On the other hand if you do not have a login system, then you can use cookies, however, this is not a foolproof method since clearing the cookie cache would allow the user to vote again.

Create table for storing user_id and post_id.
When user vote any post there will be entry in that table check database if user has already post ie entry must be there in post_id with user_id if yes then dont show voting image use AJAX for this functionality it will be great.Using Ajax you can change image ie thumb up or thumb down .
