Session variable arrangement for user management in multiple roles

Question

How can I manage same session variables for two users one admin and another his subordinate. so that admin can visit in his sub-ordinate user accounts without getting logged out of his own ??

Answer 1

So you have two user groups admin and staffs. I would have designed the database as tbl_users(id, username, usertype). Here usertype is an enum containing either 'admin' for admin or 'staff' for staff. When the user logs in, i would put the usertype and username in the session variable. Depending on this value (usertype) I would allow admin and staff functions. ie if usertype is admin then allow the user to query all the other staff data, else dont allow.
