Can not extends core Exception.php - El Forum - 05-10-2012

Hi, I'm trying to extend the Exception but always receive Fatal error: Call to undefined function. I tried to add function to both the system/core and application/core/MY_Exceptions.php. Both failed.
Code:
class MY_Exceptions extends CI_Exceptions
{
// function __construct()
// {
// parent::__construct();
// }
public function foo()
{
echo 'foo';
}Code:
class Users extends CI_Controller
{
public function index()
{
foo(); // not work
show_error('bar'); // worksThanks!

foo() is a method of the MY_Exceptions class. You can't just call it like a procedural function. I'd suggest reading some more about object-orientated (OOP) PHP programming and how functions / methods / etc. work.

So, how can I call show_error() anywhere in CI_Controller/CI_Model ... ? If I remove show_error() in system/core/Exceptions.php, it will not work.

Because show_error() by itself is a procedural function inside of system/core/Common.php, which in turn calls the show_error() method of the Exceptions class.
Not 100% how it works, but as an example:
Code:
show_error(); // procedural
$exc = new Exceptions();
$exc->show_error(); // Object orientated class method.Can not extends core Exception.php - El Forum - 05-13-2012

Ah, great reference. Thanks a lot Aken.
