Question

I am using bonfire for my project.

I have to fetch userid from the database according to username and use that userid in every view.

Right now what I am doing is I have a model function and that function is called in every controller function to fetch that userid and then userid is set to view page.

I have to repeat that piece of code for every controller function,
My query is that Is there a way to just a userid once in the controller and use that userid for every view.

my controller function :-

class asd extends Admin_Controller {
protected $role;   
public function _construct(){
    parent::_construct();
     $this->load->library('users/auth');
     $this->load->model('helpdesk_model');
     $role = $this->helpdesk_model->getRole($this->auth->username());
}
}

I am using Template::set('role',$role); in my controller function
my view :-

<?php echo Template::get('role); ?>

Its showing undefined variable role 🙁

My model :-

function getRole($username) {
        $this->db->select('role_id');
        $this->db->where('username',$username);
        return $this->db->get('tbl_users')->row();

    }

Add a variable to the controller and initialize it in the constructor:

class Some_controller extends CI_Controller {
    protected $data;

public function __construct() {
       parent::__construct();
       $this->load->model('some_model');
       $this->data['user_id'] = $this->some_model->get_user_id();
    }

    public function index() {
        $this->load->view('my_view', $this->data);
    }
}

In the view you can access it like this:

echo $user_id;
