I'm creating an addition to my vbulletin.

I'm getting this error:

Quote:

Warning: Cannot add header information - headers already sent by (output started at /home/sites/home/web/gathering/pw_event_whois.php:3) in /home/sites/home/web/gathering/admin/functions.php on line 1490

Here is the code:

PHP Code:


			
<?

require('global.php');



if ($bbuserinfo[userid]==0) {



//Send user to the registration page

show_nopermission();

} else {



//Enter the username into pw_whois





mysql_query("insert into pw_whois (eventid, username, userid) values ('7', '$bbuserinfo[username]', '$bbuserinfo[userid]')");





//Send the user back to the calendar





echo ("<html><body onload=document.location.href='http://www.powwows.com/gathering/pw_calendar/pw_event_display.php?eventid=7'></body></html>");



}

?>

Thanks

Two things to check:

a) make sure there are no blanks after the closing > at the end of the file.

b) set your cookie domain in your control panel. I have no idea why this has an effect, but it has worked for others.

How do I set the cookie domain?? What should it be set to??

Little hint, use the stuff from vB to access the DB. Makes your life easier

I'm using global??? What else can I use??

Well, there are 2 things specially i dont like in that thing

PHP Code:


			
mysql_query("insert into pw_whois (eventid, username, userid) values ('7', '$bbuserinfo[username]', '$bbuserinfo[userid]')");



//Send the user back to the calendar



echo ("<html><body onload=document.location.href='http://www.powwows.com/gathering/pw_calendar/pw_event_display.php?eventid=7'></body></html>");

You can make thse 2 nicer if you FIRST use the database class of the board and SECOND if you redirect by header (wich is smother).

Would look like this for your example:

PHP Code:


			
$DB_site->query("insert into pw_whois (eventid, username, userid) values ('7', '$bbuserinfo[username]', '$bbuserinfo[userid]')");



//Send the user back to the calendar



header ("Location: [url]http://www.powwows.com/gathering/pw_calendar/pw_event_display.php?eventid=7[/url]");

But i would not do a full url in these scripts, make it more variable, this saves you headaches. Feel free to copy paste this.
The reason to use the class is, that you use the data from the class AND use the same error reporting tools. If something happens, you get informed...

I tried to use the headers, but I got errors about headers already being set. I'll change the other part.

Thanks

I'm still having problems with the cannot set headers error:

Warning: Cannot add header information - headers already sent by (output started at /home/sites/home/web/gathering/pw_event_whois.php:3) in /home/sites/home/web/gathering/admin/functions.php on line 1490

Any ideas??

Can someone help??

Why do I get this header error?

It is not a VB3 engine, just a parsed copy!
