fdf_get_attachment - Extracts uploaded file embedded in the FDF

array fdf_get_attachment (resource $fdf_document, string $fieldname, string $savepath)
DESCRIPTION
Extracts a file uploaded by means of the "file selection" field $fieldname and stores it under $savepath.
PARAMETERS
o $fdf_document
- The FDF document handle, returned by fdf_create(3), fdf_open(3) or fdf_open_string(3).
o $fieldname
-
o $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 exist-
ing file under the same name will be overwritten.

check for the basename it was stored under.

o$path - path were the file got stored
o$size - size of the stored file in bytes
o$type - mimetype if given in the FDF

$fdf = fdf_open_string($HTTP_FDF_DATA);
$data = fdf_get_attachment($fdf, "filename", "/tmpdir");
echo "The uploaded file is stored in $data[path]";
?>
