Ok here what you have done wrong
Make file name in your application/library directory:
MY_Form_validation.php
then in your class
Code:
class MY_Form_validation extends CI_Form_validation
{
function mytest()
{
echo 'this is test';
}
}in your controller
Code:
class Test extends Controller
{
function Test()
{
parent::Controller();
}
function index()
{
echo 'hello';
$this->load->library('my_form_validation');
$this->my_form_validation->mytest();
}
}I bet this will work

Do NOT load the MY_Form_validation extension library. Load Form_validation as you would normally.
The MY_Form_validation extension class will be loaded by CodeIgniter automatically.
Code:
$this->load->library('form_validation');
$this->form_validation->mytest();@dixcoder, I suggest you go back and read the user guide again before giving people help.

Just in case someone still needs this:
The error is generated by a bad naming in the file names and class names. This is in direct correlation with the prefix definition in 'config.php' file :
Code:
$config['subclass_prefix'] = 'MY_';Considering that the prefix is 'MY_' then in application/libraries create a file named 'MY_Form_Validation.php' with content:
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/*
* Created on Mar 24, 2012
*
* To change the template for this generated file go to
* Window - Preferences - PHPeclipse - PHP - Code Templates
*/
class MY_Form_validation extends CI_Form_validation
{
function __construct($config = array())
{
parent::__construct($config);
}
function yourAdditionalFunction($someParam)
{
}
}
?>Then in your controller use 'form_validation' as you would normally use:
Code:
$this->load->library('form_validation');
$this->form_validation->set_rules('firstname', "username", "trim|required");
$this->form_validation->set_rules('lastname', "password", "trim|required");
//run your function
$ret = $this->form_validation->yourAdditionalFunction('The Param');Good luck!
