It looks like the header error is because of a conflict in the header.php file sending information before the setcookie(); command in poll.php. Apparently setcookie(); technically sends headers to the client computer similarly to normal http headers. If any content (i.e. “echo” commands or text) is sent to the client before setcookie(); is used, an error occurs.
There are a couple ways to fix this, but a quick [and sloppy] hack is to edit the index.php file in your template and change:
<?php get_header(); ?>
<?php vote_poll(); ?>
to
<?php ob_start();
get_header();
vote_poll();
ob_end_flush();
?>
It fixes both the error that you’re seeing and also allows the cookie to function properly. In programming terms, it would be much better to re-code the polls.php and get the setcookie(); function to work earlier before any of the content is sent to the client. The ob_start(); and ob_end_flush(); basically creates a buffer for php to store all the information until the headers are fully established and then send the data to the client at once. So long as there isn’t a tremendous amount of stuff in the headers.php and poll.php files, everything should be ok.
If anyone knows how to successfully re-code the polls.php file, any help would be appreciated (so that the hack isn’t required) ??
