php dynamic page

Hi folks, I am working on modifying a Joomla CMS component called j quarks, it does almost all what I need for my quiz system to work, however, I intend to enhance the component and at the end of the quiz (if a score of 100%) , have the user print out a certificate of completion with his name , quiz name , and date quiz taken .  I have never programmed anything big on php, I undertand the code, but I am more a Asp.net person..  Is there any php guru here that can help me building this page, or at least point me into the right direction.   This are the files I have .
The first one (form.php)  is a form that user fills out once he completes the quiz, and ask for its name and department  ->

next step is the quiz result pages which I have included a link to a new page  . I added to it a link page to a certificate php page that I need to populate

How can I pass the values from the form to this page?

default.php  (results page)

    $url = JRoute::_("components/com_jquarks/assets/stylesheets/jquarks_style.css");
    $document =& JFactory::getDocument();
    $document->addHeadLink($url, "stylesheet", "rel");
?>
