How do I design my access control system ?

amitdgr · 04-17-2009, 09:47 AM

Hey guys,

I am working on a small erp like application (based on PHP/MySQL). I need to implement RBAC system in the application.

What I need ...

1) The application needs to have users with around 5 different roles. Super Admin, National admin(diff. national admins for diff. countries), Zonal Admin, Sub-Zonal Admin, user.

2) The Super Admin can access and control everything.

3) A National admin can see users and access details that are local to his/her country, a zonal admin can see users and functions only under his/her zone and so on.

4) I also need to show different menus for different user roles.

What I thought might work....

1) One table will store user details, one will store role details, one will store location access details. We have to map these 3 tables to get the exact access level of the particular user. I really have no idea how to go about this.

2) For the menu, I will create 5 different menus for 5 different users and then show the particular menu depending on his role. Is this a good way to go about this ?

I am completely lost and confused. All my efforts so far have been fruitless.

I think your DB tables look pretty good.

For the menu (and all other places) i would implement something like:

PHP Code:


			
$currentUser = new user()->getUserBySession();

if($currentUser->hasAccess("edit-user"))
{
  // Has XS
}
else
{
  // Had no XS
}

Oh Jim, just to be picky and boring as usual:

PHP Code:


			
$instance = new Object()->method();

Will result in a parse error ;)

As for the real question, Wildhoney gave a good idea about this in this thread:
