[quote author="InsiteFX" date="1296127109"]It returned 1 for the row because it did find the row in the database.

It's not right! A session var that is not set or is set as empty like this:

Code:
$this->session->set_userdata('username',"");

doesn't exist, so the statement

Code:
if($this->session->userdata('username') == "")

returns TRUE.
