# fdf_get_attachment

(PHP 4 >= 4.3.0, PHP 5)

fdf_get_attachment -- Extracts uploaded file embedded in the FDF

## 说明

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`.

## 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.

  > 注意: 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.

## 返回值

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

## 范例

例 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]"; ?>`
