Question

I am new to this codeigniter. I am building a application where in user roles play a important role. In a controller i want to check if user has a particular role or permission and then give access to functions. I was wondering if i can create a flow such that i don’t need to check permissions or roles for each controller, when extending only this can be done. Can i do so?

/** Update **/

How will i do if i want to set permissions for each method in a controller or only some methods in a controller.

    <?php
class Secure_area extends CI_Controller 
{

    function __construct($module_id=null)
    {
        parent::__construct();  
        $this->load->model('Employee');
        if(!$this->Employee->is_logged_in())
        {
            redirect('login');
        }

        if(!$this->Employee->has_permission($module_id,$this->Employee->get_logged_in_employee_info()->person_id))
        {
            redirect('no_access/'.$module_id);
        }

        //load up global data
        $logged_in_employee_info=$this->Employee->get_logged_in_employee_info();
        $data['allowed_modules']=$this->Module->get_allowed_modules($logged_in_employee_info->person_id);
        $data['user_info']=$logged_in_employee_info;
        $this->load->vars($data);
    }
}
?>

put every thing that you want to do first in __construct….
