i changed it. but it still doesn't work. it doesn't care photo_check function.

Code:

<?php

    function photo_check()
    {
        if (!isset($_FILES['h_photo'])) {
            $this->form_validation->set_message('photo_check', 'Upps!..');
            return false;
        }
        else {
            return true;
        }
    }
    
    function photo_add()
    {        
        $config = array(
               array('field' => 'h_photo'  ,'label' => 'Hook Photo'  ,'rules' => 'callback_photo_check'),            
            );
        $this->form_validation->set_rules($config);              
        
        if ($this->form_validation->run() == FALSE)
            {
                // bla bla...
            }
            else
            {
                // bla bla...
            }      
    }
?>
