Hi everone. i am developing my first MVC pattern app and have few questions about ci.

1-) i do validation like below but i didn't understand what for trim or xss clean validation options. Normally they are used for trim string or clean string against xss codes but "$this->form_validation->set_rules('i_fullname', 'lang:fullname', 'trim|required|xss_clean');" this line only set rule, don't manupulate i_fullname input with trim or xss clean also this line doesn't return any manupulated value.

Code:
// Collectiong User Input
            $fullname = ucwords($this->input->post('i_fullname'));
            $birthdate= convert_datetime($this->input->post('i_birthdate'), 'mysql');
            $country= ucwords($this->input->post('i_country'));
            $city = ucwords($this->input->post('i_city'));
            $email = $this->input->post('i_email');
            $username = $this->input->post('i_username2');
            $password = $this->input->post('i_password2');
            $password_confirm = $this->input->post('i_password2_confirm');
            $captcha = strtoupper($this->input->post('i_captcha'));
    
            // Validation
            $this->load->helper('form');    
            $this->load->library('form_validation');
            $this->form_validation->set_error_delimiters('<span class="info error">', '</span>');
            $this->form_validation->set_rules('i_fullname', 'lang:fullname', 'trim|required|xss_clean');
            $this->form_validation->set_rules('i_birthdate', 'lang:birthdate', 'trim|required|xss_clean');
            $this->form_validation->set_rules('i_country', 'lang:country', 'trim|required|xss_clean');

2-) I wrote example of my controller, my code logic is like that. am i doing MVC pattern with proper way ? Can you suggest better coding patterns ?

Code:
function email_confirmation($membership_type)
    {
        // Collectiong User Input
        $email = $this->input->post('i_email');
        
        // Validation
        $this->load->helper('form');    
        $this->load->library('form_validation');
        $this->form_validation->set_error_delimiters('<div class="error">', '</div>');
        $this->form_validation->set_rules('i_email', 'lang:email', 'trim|required|valid_email|xss_clean|callback__email_check');
        
        if (!$this->form_validation->run())
        {
            $data['content'] =  $this->load->view('hesap/register_email_confirmation_view.php', '', TRUE);            
        }
        else
        {
            // Sending confirmation e-mail
            $this->my_user->send_confirmation_email($email, $membership_type);
            
            $content_data = array(
                'email' => $email
            );
            $data['content'] =  $this->load->view('hesap/register_email_confirmation_sended_view.php', $content_data, TRUE);            
        }
        
        // Page data
        $data['page_title'] = 'My Page';
        $data['page_description'] = 'example description';
        $data['js'] = '$(function() { hesap = new exampleJsClass(); });';
        $this->load->vars($data);
        $this->load->view('layout/default');
    }

3-) I want to use validation callbacks global. For example i have callback like below i want to use that in many controllers, i don't want rewrite same code again. What is proper way of done that ?

Code:
function _username_check($username)
        {
            if (!$this->user->is_username_available($username))
            {
                $this->form_validation->set_message('_username_check', $this->lang->line('not_available_resource'));
                return FALSE;
            }
            
            if(preg_match('/[^A-Za-z0-9_$]/', $username))
            {
                $this->form_validation->set_message('_username_check', $this->lang->line('valid_username'));
                return FALSE;
            }
            
            return TRUE;
        }

Thank you very much
