FileReference doesn't work with PHP Globals

Question

<help>,
Ok so this is my problem. I have a flash movie that allows
users to uploads two images to a server. What I'm trying to do is
have the uploaded images go directly to their user's directory. I
need the upload.php file to figure out which person is uploading an
image. The php page that handles the file uploads will not read in
any global variables (i.e. POST, GET, SESSION, COOKIE). Also
FileReference.upload() doesn't allow you to send any GET / POST
vars along with it (as far as I have tested and read about). I've
been working on this for four days now and have concluded it's
something to do with the Flash FileReference calling the php page.
I believe for some reason when FileReference calls the php page the
web server doesn't like/allow/understand how the page is called so
it denies any global var requests. I know its flash because it
works if I use an html front end with the same php uploader page.
So the goal for you 'out of the box' thinkers is to get one
single darn global variable pulled into the php upload page. The
ONLY way I can think of doing this is when every time a user
creates an account and their folder is created, it copies the php
upload file their directory. Then in flash when a user needs to
upload its calls the upload file in each persons upload directory.
Needless to say I do not want to do it this way but I'm running out
of ideas.
P.S. someone has suggested uploading the images to a temp
file name and then immediatly move the image to the users folder
but I I'm tentive to do it that way since you could get two people
uploading at the same time and one person would get the second
person's image and the second person would get an error.
<!--- actionscript code
this._fileRef.upload("upload.php"); <---- works
this._fileRef.upload("upload.php?user_id=4"); <---- does
not work
//-->
<?php
session_start();
$user_id = $_SESSION['user_id']; // Does not work
$user_id = $_COOKIE['user_id']; // Does not work
$user_id = $_GET['user_id']; // Does not work
$user_id = $_POST['user_id']; // Can't do with FileReference
class
?>
</help>

Answer 1

This may help. You can pass some URL encoded data with the
FileReference
upload method.
file_fr.upload("upload.php?testvar=Hello World " +Date());
Then this is a demo on how you can see that data, which you
would need to
rework to use to set the path.
<?php
if ($_FILES['Filedata']['name']) {
$uploadDir = "images/";
$uploadFile = $uploadDir .
basename($_FILES['Filedata']['name']);
move_uploaded_file($_FILES['Filedata']['tmp_name'],
$uploadFile);
$filename = "output.txt";
$fp = fopen( $filename,"w+");
fwrite ( $fp, "Test" );
fwrite ( $fp, $_REQUEST['testvar'] );
fclose( $fp );
?>
