FileManager For TinyMCE not getting variable - php

Question

I am using TinyMCE as a WYSIWYG editor.
It is working perfectly, except for the image upload directory. I want each user to have their own directory in the images directory, but I cannot get it to work.
I am passing the user id in the URL and have tried adding the code to get it from the URL in the config.php file where the directories are defined, but the $user_id value remains empty.
Any assistance would be great.
The URL:
http://mydomain.co.za/index.php?user_id=1
The Code:
<?php
$user_id= htmlspecialchars($_GET["user_id"]);
// The URL that points to the upload folder on your site.
// Can be a relative or full URL (include the protocol and domain)
$imageURL = 'http://mydomain.co.za/images/'.$user_id;
// Full upload system path. Make sure you have write permissions to this folder
$uploadPath = '/home/username/public_html/editor/images/'.$user_id;
//We create the directory if it does not exist - you can remove this if you consider it a security risk
if(!is_dir($uploadPath)) {
mkdir($uploadPath,0755,true);
}
//Create thumb directory if doesn't exist
if(!is_dir($uploadPath . 'thumbnail')) {
mkdir($uploadPath . 'thumbnail',0755,true);
}
//Allowed extenstions
$allowedExtensions = array('jpg','gif','jpeg','bmp','tif','png');
//Maximum upload limit
$sizeLimit = 2 * 1024 * 1024;
function isAuth() {
//Perform your own authorization to make sure user is allowed to upload
return true;
}
Is it possible the reason is because it is not in the main php file?
Or Can I get the variable from the URL?
They suggested on their Instructions that I add $userId = Auth::getId(); but id returns an empty value. Plus I have no idea what that command is executing.
PLEASE NOTE:
the file management is being done by TinyMCE Image Uploader & Manager
UPDATE:
By adding the $actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; echo $actual_link; I noticed by the time the $_GET command is rung the URL has changed to http://mydomain.co.za/tinymce/plugins/lioniteimages/connector/php/gallery.php, but in the browser URL bar, the URL is still the same with the variable.
Is there anyway to access that URL instead of the one i am getting?

Answer 1

I found the solution.
Simple enough, just created a session and the problem was solved.
I was able to get the variable from the session.
