Question

I would like to connect to function world() but I get an error. Do you know what I have to do? There are my first steps with CodeIgniter – I’m doing this tutorial.

Urls I’ve tried:

• localhost/nauka/index.php/hello/world
• localhost/nauka/index.php/Hello/world

Error:

Fatal error: Class ‘Controller’ not found in C:\wamp\www\nauka\application\controllers\hello.php on line 5

Answer 1

Your controller should extend CI_Controller

class Hello extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }

This may be different for older versions but you shouldn’t be using versions that don’t extend CI_Controller anyhow.

Also, you need the parent::__construct in there
