Polls

ltm

I want to generate a simple poll application and restrict one vote per day.

For this, I decided to insert the IP address of each computer and the date along with vote into a database and then perform a check each time anyone votes. However I used the variable $REMOTE_ADDR to grab the ip address which is not correct I believe because many of us in the office seem to have the same value for that.

Is there another way to develop a poll script with the restriction?

Thanks in advance!

Hi,

Saving IP addresses for your polls isn't the right way, because hosts behind a masquerading interface or a proxy server have the same IP address for the server your poll is running on. You should set a cookie on computers which were used to poll. So the computer and not the interface/router/proxy is identified.

I've tried setting cookies for other purposes before but it doesn't seem to work......The cookie seems to expire once the browser is closed and that permits the person to vote more than once a day.

Do you have any cookie setting script available??

Thanks

If your cookie is deleted when the browser is closed, you didn't set an expire value for it.
setcookie("cookie name", "cookie value", time() + 3600); for example will keep your cookie one hour.
Take a look at http://www.php.net/manual/en/function.setcookie.php for more information on setting cookies.

If you give me your mail address (e.g. per PM), I'll send you a poll script I wrote for my school's homepage.
