The page is generated. At the point that the page is generated, you are
either logged in, or not logged in.
If you are not logged in, then presumably an option to log in is
displayed, and then presumably the whole page is reprocessed from the start.
But, this time round, you can:
(a) invoke a session handler
(b) process the log in details before you do anything else
(c) store the log in state and username in a session variable
before processing the nav menu.
Now, if you did that first, when you get down to doing nav, you can test
the logged_in session variable, and if the user is logged_in, use the
username session variable in generating your navigation bar.
