Session variables not set
I am having an issue regarding session variables. When a user logs into the admin area I get their first and last names from a user table and store them in two session variables ($_SESSION['memberlastname'] and $_SESSION['memberfirstname'].
To track certain transactions of the database I enter selected information into a transaction log that includes the above session variables. I have recently discovered that some of the entries do not have the session variables set and thus the log field is blank.
Further, I have discovered that some users will log into the admin area via two different tabs.
So, my questions is... Is it possible that the session variables on the second tab is not properly set somehow?
