Don't really like running database queries in the controller but if you insist.........

Code:

<?php

class Welcomenote extends Controller {

        
    
    function index()
    {

        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');
        
        $this->form_validation->set_rules('firstname', 'Firstname', 'trim|required');
        $this->form_validation->set_rules('lastname', 'Lastname', 'trim|required');        
        $this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[12]|xss_clean');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|matches[confirm_password]|md5');
        $this->form_validation->set_rules('confirm_password', 'Password Confirmation', 'trim|required');
        $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');                
        $this->form_validation->set_rules('phonenumber', 'Phone Number', 'trim|required|numeric');                

        if ($this->form_validation->run() == FALSE) {

            $this->load->view('welcome_view');

        } else {
            
            $post_data = $_POST;
            unset($post_data['submit']);
            $this->db->insert('registrationform', $post_data);
            $this->load->view('success_view');

        }
    }
    
}
