Headers already send mess. in poll script

WolterTW

Hi all,

I suddenly get a headers already send notification when answering a poll question. The data is logged correctly, but when returning the poll results, the error is given above all other code.

I include the poll file in my main index. It all worked fine a few weeks ago so I assume it has something to do with my hosting provider making stupid changes. Again.

The line that gives the error (according to the message) is

setcookie($cookie_name, "1", $endtime); from the piece of code below:

if ($action=="vote" && (isset($HTTP_POST_VARS['option_id']) || isset($HTTP_GET_VARS['option_id']))) {
$cookie_name = "TrafficBuildersPoll".$poll_ident;
if (!isset($HTTP_COOKIE_VARS[$cookie_name])) {
$endtime = time()+3600*$cookie_expire;
setcookie($cookie_name, "1", $endtime);
}
}

Can someone please advise?

Kind regards,

Wolter

The error message you're getting indicates that there was some output before you attempted to send the header information....Have you sent any output prior to your setcookie funciton call?

Uhm... don´t no. I guess the only output that can be send prior to the setcookie function is the results of the poll.

As said, the poll is integrated in a palin PHP file like this.

call to the cookie script that displays the error

normal head section, body

in the body an include command to the poll script

end html/php

I just ´solved´ the problem by not placing a cookie. If you can tell me where to look for the problem. I.e. tell me how I can see if there is any output before the cookie placement it would be great

Kind regards

You cannot have ANY HTML output, ANY print(), echo(), etc. statements, or ANY whitespace that gets output before setting a cookie or sending a header()
