Downloading file using php (sending path to file)

[ZSWASZ]

Hello. I want to download file using Qt and php script on server. PHP script is like that:

@ $result["name"] = 'name.jpg';
header('Content-Type: image/jpeg');
header('Content-Disposition: attachment; filename="'.basename($result["name"]).'"');
header('Content-Transfer-Encoding: binary');
@readfile($result["name"]); @

In Qt I'm using QNetworkAccesManager and get method. Everything is working good, when the path is set in PHP file (or transmitted using $_GET). But is there any way to send path (and extension to content type) of file to download in other way then by $_GET? Sth like "RFC1867":http://www.vivtek.com/rfc1867.html ?
