Hey guys,
I am a beginner of a few weeks to PHP, and I am currently making a very simple guestbook with PHP and MySQL.

I would like to do a very simple error check on the guestbook. What I would like it to do, is If the form is submitted, it should check if the Name, Homepage, Email and Message fields are complete, and if they are not, it should return a simple: "You have not filled in _FIELDNAME_ !"

Could someone help me with this?

THanks in advance
