Access to CodeIgniter Superobject causes PHP Error of Severity:Notice - BobbyTanomred - 12-22-2022
I have a CodeIgniter library. When I access it from my controller a PHP Error of Severity:Notice is generated. However, the debugger shows that the super object exists in the library and is the CI super object.
Here is the library class:
class Auth_lib {
protected $CI;
public function __construct()
{
$this->$CI =& get_instance();
$this->$CI->load->model('auth_model');
$this->$CI->load->library('session');
}
/**
* checks if the current user is logged into a session
* @param
* @return boolean
*/
public function is_logged_in(){
$result = $this->$CI->session->userdata('is_logged_in');
return $result;
}
}
And this is how the library is called from my controller:
public function __construct()
{
parent::__construct();
$this->load->helper('url_helper');
$this->load->library('auth_lib');
// test if user is logged in and authorised, if not redirect to login controller
if($this->auth_lib->is_logged_in() != null){
// check if is admin
}
} else {
// not logged in, redirect to login controller
}
}
So, why I am getting this error:
A PHP Error was encountered Severity: Notice Message: Undefined variable: CI Filename: libraries/Auth_lib.php Line Number: 20

In the Auth_lib class, not $this->$CI but $this->CI.

Before crossing over to CodeIgniter4 i've used another solution that worked as well.
PHP Code:
<?php
class Your_class {
public function __get($instance) {
return get_instance()->$instance;
}
// You do not need: $this->CI->load->model('name');
// You can now use: $this->load->model('name');
}
