Answer 1

Firstly, I would not name function for inserting to database getHello , but rather insertHello .

Secondly, use inserting function for this purpose only, don't return some HTML code. Return boolean value and decide later what to display.

I would use something like this:

class modmyModuleHelper {

    function insertTrackCode() {
        if (!empty($_REQUEST['track_code'])) {
            $db = JFactory::getDbo();
            $query = $db->getQuery(true);
            $query
                ->insert($db->quoteName('#__trackno'))
                ->values($_REQUEST['track_code']);
            $db->setQuery($query);
            return $db->query();
        } else {
            return false;
        }
    }
}
