Extracts a file uploaded by means of the "file selection" field fieldname and stores it under savepath .

参数

fdf_document: The FDF document handle, returned by fdf_create(), fdf_open() or fdf_open_string().
fieldname
savepath: May be the name of a plain file or an existing directory in which the file is to be created under its original name. Any existing file under the same name will be overwritten.
