Just a quick note incase anyone comes across the same problem. Basic problem results from the new superglobals and having globals set to off: basic form that shows a record from database, on submit updates the record. The problem comes with validating the data, i.e. user enteres a non suitable value and you throw back the form and the error. When you pull the data from the database, the values are not in the $_POST or $_GET super globals, thus using $_POST[var] as initial value for form field doesnt work. Using $some_var as initial is fine, but if the user enteres an improper value, those values wont be available because they are then in $_POST or $_GET. The solution is simple, but it escaped me for a bit because I didnt think it would be possible: you can actually defined $_POST members within a script, thus your values from the database should be converted to $_POST or $_GET members. Hope it helps someone.
