form validation help PLEASE

[eluser]flaky[/eluser]
from what I'm seeing you've put the callback function inside the index(), which is wrong, at least php should be giving you a warning about that, you can't have a function inside a function

here the fix

Code:

<?php

class Login extends Controller {

    function Login()
    {
        parent::Controller();
        $this->load->database();
        $this->load->library('session');
        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');
    }

    function index()
    {
        
        
        $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean|callback_username_check');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|');
        
        
                if ($this->form_validation->run() == FALSE)
                {
                    $this->session->set_flashdata('message', 'Empty Fields.');
                    redirect('mains');
                }
                else
                {
                    
                    $this->session->set_flashdata('message', 'It WORKED.');
                    redirect('mains');
                }
    
    
    
    }
    
    function username_check()
    {
        $user = $this->input->post('username');
        $pass = $this->input->post('password');
        $query = $this->db->query("SELECT loginName,active FROM Member WHERE loginName='$user'
                        AND password=md5('$pass')");
        if($query->num_rows() == 1)
        {
            return TRUE;
        }
        else
        {
            return FALSE;
        }
        
    }
}
