Segments not working with file upload

[eluser]marss[/eluser]
Hi,

I'm trying to send some arguments when making a file upload, my uploadscript is a copy of the example over at http://ellislab.com/codeigniter/user-gui...ading.html

So I added two arguments:

Code:

<?php echo form_open_multipart('upload/do_upload/9/8');?>

But these two never shows up in my controller - they are output in the HTML before submitting form though.

Code:

$this->uri->segment(3)

returns nothing. I even tried looking at

Code:

$_SERVER['REQUEST_URI']

but it's actually missing there as well - but segment(1) and (2) works.. also shows up in REQUEST_URI.

Any ideas on why I don't recieve my /9/8?

Thankfull for any input!
