forcing file download location dialog rather than viewing linked file?

[eluser]Seth Setiadha[/eluser]
i'm nu here,

i tried it, seems like it succeeded
but when I open the downloaded file it's only something like 60 byte and there's nothing
i checked the path by viewing the file first and it's fine

sorry if it sounds silly, i put this code on view, it's correct right ?

pls advice
