Is that a perm?

A simple access control library for CodeIgniter. Here's a quick rundown of the features:

• Use group and/or role-based controls
• Validate single or multiple required roles
• Validate hierarchical or optional roles
• Automatic database configuration

Usage

You can set group or role-based controls.

Groups

You can use the name of the group or the group's ID

$this->perm->in_group(3);

or:

$this->perm->in_group('admin');

Roles

You can validate a single role by using the name of the role in the has_role method:

$this->perm->has_role('users_create');

You can also pass multiple required roles as an array:

$required_roles = array('admin', 'users');
$this->perm->has_roles($required_roles);

Note: You can use has_role() and has_roles() interchangeably. The has_roles() method maps to has_role().

If you want to pass a hierarchy of roles, you can do that by separating each role with a colon (:). If a user has any of the roles in the hierarchy, the method will return true.

$this->perm->has_role('admin:users:users_create');
