the data wouldn't be submitted but the form would be open for another vote which is kind of like refreshing.

Thanks anyway

yes, but if you forward them back (to the same page theyre on) the form is reset, and data will no longer be submitted on subsequent refreshes.

prevote and postvote are the same page

if all you want to do is stop refreshing from re-submitting the form, just forward them back to the page after a vote...

example:

<?php
//when someone votes
//process the vote here
//then forward them
header(\"Location: yourpage.php\"); exit;
?>

zollet, told you how to do it......

example......

<?php
$ip = \"$HTTP_SERVER_VARS[REMOTE_HOST]\";

$total = get_voted($poll, $ip, $db);

if ($total > 0) {

// redirect to resluts page or give error

echo \"<td>Already Voted</td>\";

} else {

// they have not voted, show the vote button

echo \"<td>INPUT VOTE BUTTON</td>

}


// the function............

function get_voted($poll, $ip, $db) {

      mysql_select_db($db);

      $sql = \"SELECT count(*)AS total FROM voted WHERE poll_id = '$poll' AND ip = '$ip'\";
   if(!$result = mysql_query($sql)) {
     return(\"ERROR\");
    }
   if(!$myrow = mysql_fetch_array($result)) {
     return(\"0\");
    } else {
   return($myrow['total']);
   }
}
?>

The only fool proof way to have an accurate poll is to have user regisration.

That's kinda why you have to register to vote around here too.

Thanks but that has 3 problems,
1. cookies can be disabled (unaccepted) I started using cookiewall and pick and choose which cookies to accept or deny, adaware has had nothing to do since I got it.
2. I'm using sessions in the page but I need to empty the session after each page view (and can be over 2000), so voting, going forward one page then back would be same as refreshing as the session wouldn't be valid.
3. similar to number 2, also not 100% sure how I could do it, as it would need to be flushed after each visit (browser) so they could return the next day I suppose.

Sessions and cookies (among others) aren't my strong points, how can I use then seperate them, without my code looking like the draft of war and peace. at the moment I already have about 6 or 8 session variables registered per display (each page)

I wish there was something that would easily let me do something like this:

You can do this as you havent done it before
If you did this, you can't do this again
umm your naughty you tryed to do it again

You need to store some info to know who has voted and who has not. The way I see it, you have 3 options...

1. Set a cookie after the users votes.
2. Use sessions to do the same thing.
3. Store the IP in a table in the database.
