Your uploading code is not correct, see example:

XML

<?php
if(isset($_POST['download']))
{
$filename=$_FILES['file']['tmp_name'];
header("Cache-Control: public");
header("Content-Description: File Transfer");
header('Content-disposition: attachment;filename='.basename($filename));
header("Content-Type: application/octet-stream");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. filesize($filename));
readfile($filename);
exit;
}
?>
<html>
<body>
<form method="post" enctype="multipart/form-data" action="download.php">
<input type="file" name="file" >
<input type="submit" name="download" value="download">
</form>
</body>
</html>

Note the extra attributes in the <form> tag, and the use of $_FILES not $POST to capture the file object in php. PHP will give the upload file a temporary file name called $_FILES['file']['tmp_name'] which will disappear when the script ends.
