I am trying to implement the following functionality within RIFE:
(1) User logs in to site with username/password.
(2) There is additional information about users held in a Postgresql
database table. A user can have one or more roles, each of which can be
associated with an area. Multiple roles are possible within the same
area. So, once the user is logged in (and globalvar "authid" is set), I
want to be able to do one of the following:
(a) If the user has a unique role/area combination, take them to the
home page for their user type. No problem (and this works fine).
(b) If the user has >1 role, put up a form with a select list and a
button to enable them to pick which role they want to perform.
I have implemented the role/area chooser as an embedded element of
"home", just as I have the login box (as per the numberguess example).
This is so that every subsequent template in the site can embed these
elements which will tell the user who they're logged in as and what role
they have in which area. The role and area will be set as globalvars
"roleid" and "aaid".
The embedded elements perform as expected up to a point. The login
screen comes up, I log in and it correctly reports who I am. When I
have multiple roles it correctly outputs the form to enable me to select
roles. The form submission points back to the parent element "home". I
believe this from my reading of the manual to be correct.
The maddening thing that happens when I select my role and click the
submit button is that I'm returned to the login box once more. The
"authid" globalvar has somehow been lost as a result of doing the
submission within the embedded element. I can't see what I'm doing
wrong, and have gotten totally confused by this. I don't see how I can
debug it either. I assume something in one or more of my XML files is
wrong, but I have really got stuck as to what.
