try checking network response in google dev tools inspector. if you're getting 500 script has syntax error. if seeing "record save success" message, try turning on ini_set('display_errors',1); @ top of script see if of variables missing, or echo query , check in dev tools, try query directly on mysql. note should escape variables security or use mysqli prepared statements.
