online.php header problem · **Released**: 05-02-2002

Hi all,

i have the following parse error showing up from time to time. Its not always there though and I cant really simulate it. Sometimes it just goes away if I call up online.php again, but its bugging me badly.

Warning: Cannot add header information - headers already sent by (output started at /home/blabal.../forums/online.php:2) in /home/blabla.../forums/admin/functions.php on line 1601

Line 1601 in functions.php looks like this:

1597 if ($cookiedomain) {
1598 setcookie($name, $value, $expire, $cookiepath,
1599 $cookiedomain, $secure);
1600 } else {
1601 setcookie($name, $value, $expire, $cookiepath, '', $secure);
1602 }

Any of you have an idea what might be causing this?

regards Tina

What the second line of online.php? Could it be online.php looks like this:

Code:

1: 
2: 
3: <?php
4: error_reporting(7);

(i.e you have blank lines at the top)

Hi Chen,

well yes 1 blank line before <?php.

PHP Code:


			2: <?php
3:
4: // Yes we realize that there are a lot of hard coded English words in this file.
5: // Language abstraction is planned for vB v3.0
6: 
7: error_reporting(7);

sorry, had another look, jus now. Guess that the bug?

That looks about right...

Could it be the setcookie()-function that fails for some reason and produces some kind of error output?

Hi Sparkz,

thanks for the reply. Well, yes that was my first thought, but somehow I doubt it because of the Warning regarding the header. I mean what has the cookiesetting to do with the header warning.

According to my understanding of line 1601, this comes into effect if I dont have my domainname set as the cookiepath in the adminsettings of my board, which I havent because I'm only running one board on the server, thus having that set to "/".

mmh. well I've removed the blank line before <?php now - maybe that was it ? Was that what your where trying to tell me Chen?

If some function fails and this causes any kind of output to be sent, you cannot send any more headers afterwards.

But having blank lines before <?php could also cause it.

Having the blank line actually sent a blank line to the browser, as output. And as we all know, you can't send HTTP headers after you start sending output to the browser, and since setcookie() sends a header - it failed.
