First, you have to create a new class where you will define all your rules. Let's start with this:
require_once "SimpleRoles.php";
class Ability extends SimpleRoles {
function __construct($user) {
parent::__construct();
// You should define here your rules
}
}
We place our rules inside the __construct function.
function __construct($user) {
parent::__construct();
// We put the current user roles in $user_roles.
// Please note that you can use whatever method you
// prefer for checking role membership.
$user_roles = array();
if($user != null)
$user_roles = $user->getRoles();
if(in_array('admin', $user_roles)) {
$this->can('read_article');
$this->can('write_article');
$this->can('delete_article');
}
if(in_array('moderator', $user_roles)) {
$this->can('read_article');
$this->can('write_article');
}
if(in_array('guest', $user_roles)) {
$this->cannot('all');
}
}
