get_instance problem - El Forum - 02-07-2010

Hi everyone,
I'm trying to create a new Exceptions class for a little project I'm working on but I seem to have an issue with getting the CodeIgniter instance. The error I get is:
Quote:Fatal error: Call to undefined function get_instance() in ...
My code is this:
Code:
class HUB_Exceptions extends CI_Exceptions {
private $CI;
public function __construct() {
parent::CI_Exceptions();
$this->CI =& get_instance(); //It breaks on this line here...
}
}This is my first time extending a core class, so I'm not 100% sure what's breaking here.
Any help would be greatly appreciated.
Thanks!

You are extending the core. I think you can dirtectly refer to the CI superobject as $this.

Doesn't look like I can, I tried this:
Code:
$this->session->set_item('error_heading', $heading);and got another error:
Quote:Fatal error: Call to a member function set_item() on a non-object in...

Well, JoostV you are wrong, CI_Exceptions does not use the $this as we use it in controllers.
JCianflone, I guess the problem is that the Exceptions library is loaded BEFORE the base class is loaded and even it's filed loaded.
Therefor it doesn't exist yet..

Yea, that's what I was thinking.
OK, well, lets see if I can do this same thing with hooks!

@shay You're right, did not read the question well.
