& get_instance()

good morning riends...

I'm not going to work with CI Hook. I'm trying to import "= & get_instance ()" but to no avail. I'm using version 3.1.6.

What can it be?


<?php

class Login
{
    public $CI;
    
     public function __construct()
     {
            // Assign the CodeIgniter super-object
        $this->CI =& get_instance();
     }

    function validar()
    {
        echo "validar";
        $this->CI->load->helper('url');
    }


error:

If your not going to use hooks then why is your Login.php Library in the hooks folder?

Also it depends on whats been loaded see Codeigniter.php and Loader.php in the ./system folder.

What did you Try? What did you Get? What did you Expect?

You can put your class in the Models directory or a subdirectory of Models. You will need to include it in your controller or in whichever model class is using the Login class.

Code:

defined('BASEPATH') OR exit('No direct script access allowed');
include_once(APPPATH.'models/Login.php');

class Login_controller extends CI_Controller {
...

Using composer you can store classes in a completely different directory, but the include_once is a simple way to start with non-singleton classes.
