Codeigniter 3 MY_Controller - php

Question

I have this on my MY_Controller that was located on my core folder.
<?php
class MY_Controller extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function is_logged_in($data){
$session = $this->session->userdata();
if($session['isloggedin']['username'] == ''){
return isset($session);
}else{
return FALSE;}
}
}
?>
I'm pretty sure i copy pasted the above code from some tutorial and i haven't gotten to editing it based on my needs.
Any case i have questions.
So i have a pages controller that will be responsible for giving access to some views depending on the account_type of the logged in user.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class pages extends MY_Controller {
}?>
this is my session whenever a user logs in.
$new_session = array( 'username' => $this->input->post('username'),
'email' => $this->input->post('email'),
'type' => $this->input->post('type'),
'logged_in' => TRUE);
$this->session->set_userdata($new_session);
How do i call the MY_controller function is_logged_in() from the pages controller or is the 'extends MY_Controller' automatically also calls the function is_logged_in() or do i have to basically just put it in a __construct so it automatically calls the function?
Also, how do i go about checking if a user is logged in and seeing their details?
Do i pass session_data from my controller to MY_Controller? if so, how?
Or should i just put a $this->session->userdata(); line inside the is_logged_in() function?
P.S. i have tried using Authentication Libraries but they include far too much to what i need, i just need a basic authentication. Any suggestions? that is still maintained right now.

Answer 1

you can directly call is_logged_in() function from your pages controller. just like this:
Pages.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Pages extends MY_Controller {
function __construct() {
parent::__construct(); // this will trigger the __construct() of MY_Controller
}
}
MY_Controller.php
<?php
class MY_Controller extends CI_Controller{
public function __construct() {
parent::__construct();
if( $this->is_logged_in() ) {
// do something if user is allowed to access.
}
else {
// do something if user is not allowed to access
}
}
}
