Usted necesidad de investigar cómo utilizar cookies. Si se obliga a las cookies, reducir el proxy como el spoofing "cookie" no puede llegar al cliente de la misma manera que la IP del cliente no puede llegar a sus cheques.

You need to research how to use cookies.  If you force cookies you will cut down on proxy spoofing as the cookie can not get to the client the same way the client IP can not get to your checks.

Why not donate the point when they login? The problem is that you probably do something like:

 

points = points + 1

 

In your database and thus have no idea which days they logged in. Change your database design to:

 

points (user_id, date)

 

When they login, check if an entry exists for that day:

 

WHERE user_id = $uid AND date = curdate()

 

If it doesn't add one. The get the number of points for a user, use:

 

SELECT count(*) AS user_points FROM points WHERE user_id = $uid

 

This technique has the advantage that when even if the user would use a proxy you could remove their points by looking up dates and removing any duplicates.

 

 

To create a ranking, use:

 

SELECT .., count(*) AS user_points FROM points GROUP BY user_id ORDER BY user_points DESC
