How to add events in calendar using php

I am looking for someone who can help me to add event to web calendar. I have created calendar using PHP and HTML (you can take a look at two scripts at the bottom). I also have table in DB where those events should be entered. That table has 4 columns ID, start date, end date and type. start date and end date should be entered using calendar on the web and type can be entered as text. Thank you for your time!

naviHref = htmlentities($_SERVER['PHP_SELF']);
    }
