PHP Error

Anonymous — GMT

Hi,

I get this error at www.britishgp-sc.co.uk
Anyone help?
Cheers.

Warning: Cannot modify header information - headers already sent by (output started at /home/britgpsc/public_html/index.htm:3) in /home/britgpsc/public_html/poll/poll_cookie.php on line 21

Carbonize — GMT

Self explanatory. On line 21 of poll_cookie.php you have some white space. I assume that the code ends at line 20 or 21. The end is ?>. Open the file and see if you can place the cursor beyond the ?> and if you can delete the space until the cursor is just after the ?>.

Thanks for replying so quickly, my code is as below with no spaces and it still does it

include_once "/home/britgpsc/public_html/poll/poll_cookie.php";
?>

setcookie($cookie_name, "1", $endtime);

I've cleaned it up and it still does it (

/**
* ----------------------------------------------
* this code is optional
* Important! You have to include it
* before your html code
* ----------------------------------------------
*/

$cookie_expire = 96; // hours

$action = (isset($HTTP_GET_VARS['action'])) ? $HTTP_GET_VARS['action'] : '';
$action = (isset($HTTP_POST_VARS['action'])) ? $HTTP_POST_VARS['action'] : $action;
$poll_ident = (isset($HTTP_GET_VARS['poll_ident'])) ? $HTTP_GET_VARS['poll_ident'] : '';
$poll_ident = (isset($HTTP_POST_VARS['poll_ident'])) ? $HTTP_POST_VARS['poll_ident'] : $poll_ident;

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

It looks like the spaces removed were on lines inside the functions(?) Check for [b]blank lines[/b], not spaces, especially make sure there are no blank lines after the [b]?>[/b] at the end. Here's how my code looks:

[code] /**
* ----------------------------------------------
* this code is optional
* Important! You have to include it
* before your html code
* ----------------------------------------------
*/

$cookie_expire = 96; // hours

$action = (isset($HTTP_GET_VARS['action'])) ? $HTTP_GET_VARS['action'] : '';
$action = (isset($HTTP_POST_VARS['action'])) ? $HTTP_POST_VARS['action'] : $action;
$poll_ident = (isset($HTTP_GET_VARS['poll_ident'])) ? $HTTP_GET_VARS['poll_ident'] : '';
$poll_ident = (isset($HTTP_POST_VARS['poll_ident'])) ? $HTTP_POST_VARS['poll_ident'] : $poll_ident;

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

?>[/code]

Here are some posts explaining:

"Warning: Cannot modify header information - headers already sent by...":
http://proxy2.de/forum/viewtopic.php?t=3200&highlight=cannot+modify+headers
http://proxy2.de/forum/viewtopic.php?t=3093&highlight=cannot+modify+header

The reason they end with the phrase "cannot+modify+header" is because they were located by using the search button at the top of this forum and searching for [b]cannot AND modify AND header[/b]. Just so you know you can find info that way.

Cheers,
As an aside what should my index page be like out of the three examples below;

"http://www.w3.org/TR/html4/loose.dtd">
// Important! You have to include it before your html code
include_once "/home/britgpsc/public_html/poll/poll_cookie.php";
?>

OR

"http://www.w3.org/TR/html4/loose.dtd">

// Important! You have to include it before your html code
include_once "/home/britgpsc/public_html/poll/poll_cookie.php";
?>

OR

"http://www.w3.org/TR/html4/loose.dtd">

// Important! You have to include it before your html code
include_once "/home/britgpsc/public_html/poll/poll_cookie.php";
?>

Thanks,
Ricky.

Cookie code first, before any html, and poll code wherever you want it to appear...example:
[code] /* Include this before your html code */
include "poll/poll_cookie.php";
?>

Opinion Polls
type="text/css">

vlink="#0000FF" alink="#0000FF" topmargin="0" leftmargin="0">

include_once "/home/xxxxxx/public_html/poll/booth.php";
echo $php_poll->poll_process(1);
?>

[/code]

Many Thanks!
