Additionally, depending on the name of a button to be submitted will completely fail in certain circumstances. You need to check the REQUEST METHOD.

if ($_SERVER['REQUEST_METHOD'] == 'POST')

Don't create variables for nothing

 

Stop outputting internal system errors to the user. That information is only good to hackers.
