Hope this will help you :

Note : Controller name should start with capital letter only

Load url helper first like this :

In autoload.php

$autoload['helper'] = array('url');

Or load in your Login controller like this :

class Login extends CI_Controller 
{
  public function __construct()
  {
    parent::__construct();
    $this->load->helper('url');
   }
}  

For more : https://www.codeigniter./user_guide/helpers/url_helper.html

You should not name a function of a class the same as the class. You have a function login() and the class is named login which triggers the warning on line 3. When PHP sees class and function names that match it thinks the function is the constructor for the class. But that's not what you want and is the reason you get the error on line 26.

There does not seem to be any reason for a constructor in your class. (Unless you really do need to load a helper or other library)

To fix your problem delete the index() function then rename login() to index(). Finally, use an uppercase L in the name of the class. So change this

class login extends CI_Controller {

to this

class Login extends CI_Controller {

The file name should also have an uppercase first letter i.e. Login.php
