Vote once

[Graxeon]

I'm not a real PHP guru but I can't grasp the idea of how to have a poll and make a cookie that will disable users from voting for a certain amount of time.

 

Here's a voting script that I found very useful:

 

http://www.w3schools.com/php/php_ajax_poll.asp

 

But just by refreshing the page I can vote again. I tried googling "how to save a cookie" and this is what I came up with:

 

http://blazonry.com/javascript/cookies_save.php

 

But I don't know how to combine those 2 scripts.

 

Any help?

 

 

Edit:

 

Oh I also did search on these forums and found a few posts with the same problem...but they were from people that didn't speak newbie xD

Are you sure you wanna go with cookies? Someone can just delete the cookie and vote again, and again, and again...

 

you're better off doing it by IP address

Well...for ip logging I found this but I still need help combing the 2:

 

<?php
$ip = $_SERVER['REMOTE_ADDR'];
$pagina = $_SERVER['REQUEST_URI'];
$datum = date("d-m-y / H:i:s");
$invoegen = $datum . " - " . $ip . " - " . $pagina . "<br />";
$fopen = fopen("ips.html", "a");
fwrite($fopen, $invoegen);
fclose($fopen);
?>

Oh shoot posted in the wrong forum. No wonder the replies are a little slow in here

 

Someone move this to PHP Coding Help, please. This has nothing to do with Zoomla or any other PHP app, sorry my mistake  xD

Moved.

 

In short:

 

 

 

when user votes, check the database if that user has voted.

    if he hasnt

        Store the IP and time of vote in the database.

    if he has

        get the time of his last vote and the current time to do your time-span calculation

                if X time has passed

                    He can vote. register his vote and update database so time of his last vote is the current time

 

 

If you want to implement cookies, you can fit that in there as well. but like i said, very easy to bypass
