Codeigniter can't get a simple post data variable

THIS IS FIXED, I h开发者_如何转开发ad named my function the same name as my controller, changed function name from login to do_login, now works a treat, thanks all

Hi this should be really simple:-

Im writing a php site using CI

im trying to get a simple POST variable im my controler using:

public function login()
{
    $something = $this->input->post('something');
}

This on a controller name Login.php , the idea is have a form pass the POST data to this function at login/login, but I get this error

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Login::$input

Filename: controllers/login.php

Line Number: 38

( ! ) Fatal error: Call to a member function post() on a non-object in C:\wamp\www\rcity\application\controllers\login.php on line 38

Ive tried get_instance(), but I can refer to everything else as $this inside the controller, as soon as I mention POST it dies, and off what ive read the input class is already loaded so thats not the issue, any ideas?

Thanks

HERES the full file for login.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Login extends CI_Controller {

    public function index()
    {
        $data = array(
               'title' => '*** | Login',

                );
                $this->load->helper('login_helper');
                $this->load->view('head_view',$data);
                if (check_login()==TRUE){$this->load->view('header_logged_in');}
                else {$this->load->view('header_logged_out');}
                $this->load->view('nav_view');
                $this->load->view('login_view');
                $this->load->view('footer_view');

    }
        public function login()
        {
            $something = $this->input->post('something');
            $this->load->helper('login_helper');

        }
}

You can't name your function the same as the controller... that would make it a constructor.

You're best best is to do this:

function __construct()
{
    parent::__construct();
    // the stuff you currently have in index()
}

public function index()
{
    $this->login_user();
}

public function login_user()
{
    // your code here
}
