Question

if(isset($_POST['submit'])) {

   $url = "http://localhost/myuploader/upload.php"; // e.g. http://localhost/myuploader/upload.php // request URL
    $filename = $_FILES['file']['name'];
    $filedata = $_FILES['file']['tmp_name'];
    $filesize = $_FILES['file']['size'];

    if ($filedata != '')
    {
        $headers = array("Content-Type:multipart/form-data"); // cURL headers for file uploading
        $postfields = array("filedata" => "@$filedata", 
                            "Attchment1" => $filename,
                            "anrede" => trim($_POST['anrede']),
