How Can I insert the username of who submitted a form to the database?

When you include global.php, it does a lot of stuff for you like makes sure the user is logged in (actually you have to check that - if the user id is '0' then the user is an unregistered guest). So hopefully the answer to your question is that it should all be handled by including global.php.

(If this doesn't answer your question I'll let someone else try )
