Is this error Unable to add cookies, header already sent.

[Frank H. Shaw]

I have found the following does give me a actual user logon

PHP Code:


$vbulletin->userinfo['userid']; 


IS THIS IS FOR THE CURRENT LOGON USER?

But I have run in to some trouble and need some understanding and help


Get the following error message:

Unable to add cookies, header already sent.
File: C:\Inetpub\vhosts\burningtaper.org\httpdocs\forums \calendar.php
Line: 119

When I try to output the value to my screen at the top of my calendar page.

PHP Code:


print($vbulletin->userinfo['userid']);       // This works fine not really?

print_r($vbulletin->userinfo['userid']);       // This does not? 


At least at first glace but if I try to redisplay pint() or print_r() the page again by selecting a different calendar from the "calandar jump" drop down at bottom of the page then i get the error again.

// But this does not work why

PHP Code:


unset($mycurrentuser);
$mycurrentuser = $vbulletin->userinfo['userid'];

print_r( "My Current User is :" . "   " . $mycurrentuser); // does not work 


The one above fails when the page is displayed first time.

Why same location in script?

In the file calendar.php right after the Next line after the line 119

START MAIN SCRIPT

Get the following error message either way:

I tried to also use the following:

Just add the following PHP code

PHP Code:


unset($mycurrentuser);

$mycurrentuser = $vbulletin->userinfo['userid'];

ob_start();

echo( "My Current User is :" . "   " . $mycurrentuser);


ob_end_flush();

ob_end_clean();

In the file calendar.php right after the Next line after the line 119

PS I hope the PHP tags are to ones liking now?

--------------- Added [DATE]1232922604[/DATE] at [TIME]1232922604[/TIME] ---------------

The print() really does not work but its action leads me to think that the whole thing has to do with placement.

The hooks must have something to do with this problem i am dealing with -

Can or does some one have some rules of tumbs and guidelines on when and when not can i create output with out interfering with the action of the calandar.php?

THANKS
