PHP Manual: Extracts uploaded file embedded in the FDF

Description

array fdf_get_attachment(resource $fdf_document, string $fieldname, string $savepath)

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

Parameters

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.

Note:
There seems to be no other way to find out the original filename but to store the file using a directory as savepath and check for the basename it was stored under.

Return Values

The returned array contains the following fields:

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

Examples

Example #1 Storing an uploaded file

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