Error: Unable to add cookies, header already sent
 

Hello,

I'm extremely new to vBulletin and forums in general so your patience is greatly appreciated. :o

I need help in determining why I get an error "Unable to add cookies, header already sent." when I try to initialize the user class of the datamanager.

Here are the specifics of how I started with a basic php file that I stored in the same directory of vbulletin's global.php file.

I started with a very simple script to echo content and it worked. Note it is running in the forums directory where the global.php file resides.
"
echo "i'm in", 1, 2, 3, "... 1st line of code. Yea! Oh and BTW Hello World!";
"
And the script ran fine with no errors. :D

Then as soon as I added the following code:
"
// init user datamanager class
$newuser =& datamanager_init('User', $vbulletin, ERRTYPE_ARRAY);
echo "i'm at the last line of code. sniff sniff... Good bye World!";

I get the following output with one error:

"i'm in123... 1st line of code. Yea! Oh and BTW Hello World!
Fatal error: Call to undefined function datamanager_init() in C:\inetpub\vhosts\scopeyourdate.com\httpdocs\forum s\testit.php on line 5":(

So I figured I would add a line I?ve seen in samples to include the global.php right before I initialize the ?user? datamanger class as such:
"
require_once('./global.php');
":)
so my final script looks like this:
"
//TB 1st test of creating a user
echo "i'm in", 1, 2, 3, "... 1st line of code. Yea! Oh and BTW Hello World!";
require_once('./global.php');
// init user datamanager class
$newuser =& datamanager_init('User', $vbulletin, ERRTYPE_ARRAY);
echo "i'm at the last line of code. sniff sniff... Good bye World!";
":erm:

and I get the following output with an error that I don't know how to resolve:
"
i'm in123... 1st line of code. Yea! Oh and BTW Hello World!


Unable to add cookies, header already sent.
File: C:\inetpub\vhosts\scopeyourdate.com\httpdocs\forum s\testit.php
Line: 3
":confused:

Note, I have version 3.8.3 with the blog and google adsense features.

Please advise this newbie.

Thank you for any help you can provide.:)

Okay nevermind I found a post http://www.webhostingtalk.com/showthread.php?t=656386

where a user specifically said to take out things like "echo". I did that and now my script works. Thanks!!! Who knew?!

I don't know that you needed to remove the 'echo' (although I highly recommend not using echo), I think you just needed to put the echo statement *after* you required global.php. The global file needs to be required before there is any output from the script. (Also, the code/php/html tags are the best things to use when you include code in your post.)

You can have any output before including global.php.

You may also need to include the user data manager file.

I just wanted to say thank you for responding so quickly.

And also for letting me know the forum etiquette regarding posting code.

I really appreciate it!:D
