答

Did you set the register_global directive to ON in your PHP configuration ?

Plus try using $_FILES instead of $HTTP_POST_FILES, as this last one in now getting old

答

That just means you DID NOT define $HTTP_POST_FILES

Define it and you should be good.

If you are trying to use the now deprecated $HTTP_POST_FILES, don't.
Use $_FILES instead.
