Hi,
I'm in the middle of finalizing the new design for a site (deadline is tomorrow).
The only problem that remains is one with my poll.
I've copied the code (file is called poll.php) here and have asked two questions at the bottom of this message.
<?
// DEFINE THE VARIABLES //
// title of this poll
$title = "What do you think of the new BF look?";
// closing date for this poll in MM/DD/YYYY format
$closingDate = "1/1/2070";
// text file that stores vote choices and totals
$pollFile = "poll.txt";
// text file that stores IP addresses
$ipFile = "ips.txt";
// full path to your CSS style sheet
$styleSheet = "http://yoursite/style.css"; // leave blank if you aren't using this
// DO NOT EDIT BELOW THIS POINT UNLESS YOU KNOW PHP! //
// DEFINE THE FUNCTIONS //
// check if the poll has closed
function is_closed() {
global $closingDate;
// split the closing date into month, day, and year
$closingDate = explode("/", $closingDate);
// get today's today to test against the closing date
$today = getdate();
$message = date("l, F j", mktime(0,0,0,$closingDate[0],$closingDate[1],$today[year]));
// if today's year is greater than the closing year, return true
if ($today[year] > $closingDate[2]) {
return $message;
}
// if today's year is equal to the closing year
elseif ($today[year] == $closingDate[2]) {

if ($today[mon] > $closingDate[0]) {
return $message;

return $message;
}

}
}

}

}
// check if the user has already voted
function has_voted() {

// get the array index number for the name of this vote
$name = $i - 1;
// if this vote choice is this user's selection, increment it
if ($votes[$name] == $vote) {
$votes[$i]++;
}
// if this vote IS the last choice
if ($i == (count($votes) - 1)) {

}

displayPoll("The poll closed on " . $message . ".");
exit;
}
// if the user is not voting, display the poll and exit
if (!isset($vote)) {
displayPoll("");
exit;
}
// if the user has already voted, display the poll and exit
if (has_voted()) {
displayPoll("You already voted.");
exit;
}
// add the user's vote
addVote($vote);
// display the poll
displayPoll("");
?>
Two questions:
1) Can I put class elements (of my external CSS I'll link to by entering the full path at the top of the code above) in thhe <td> tags, like <td class="pl">?
2) The results need to be opened in a new window with a fixed size when the "vote" button is clicked on. I've heard that this can be done by using a <script> tag, but exactly how do I need to do this and where do I need to place the <script> tag?
Thanks!
