File data missing

[tomorrowevening]

ofxHttpForm form;
form.action = "http://localhost:8888/upload.php";
form.addFormField("userID",  ofToString(userID));
form.addFile("file", "log.txt");
form.method = OFX_HTTP_POST;
http.addForm( form );

$user  = $_POST["userID"];
echo "User:  " . $user;
echo "\n";
echo "POST: " . count($_POST) . "\n";
echo print_r($_POST);
echo "\n\n";
echo "FILE: " . count($_FILE) . "\n";
echo print_r($_FILE);

Result:

User:  0
POST: 1
Array
(
    [userID] => 0
)
1

FILE: 0
1

POST variables get sent over, but why don't I see anything added through ofxHttpForm's::addFile()?

PHP required the absolute path of the destination, thanks to this link, now works!

<?php

$uploaddir = '/Users/colind/Projects/C++/openFrameworks/projects/Server/bin/data/logs/';

if (is_uploaded_file($_FILES['file']['tmp_name'])) {
    $uploadfile = $uploaddir . basename($_FILES['file']['name']);
    echo "File ". $_FILES['file']['name'] ." uploaded successfully. ";
    if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
        echo "File is valid, and was successfully moved. ";
    } else
        print_r($_FILES);
} else {
    echo "Upload Failed!!!";
    print_r($_FILES);
}

?>
