WWWForm Array Files Upload ?

Hey ,

i build a Unity Update for my game inside the Editor, but i have one problem with the WWW Uploader.
he uploaded only one file, but the second not.

using UnityEngine;
using UnityEditor;
using System;
using System.Collections;
using System.IO;

public class UpdateGameWindow: EditorWindow
{
      
    void OnGUI()
    {
        ....
        ..
        .

        if (GUILayout.Button("Upload - All", GUILayout.Width(150)))
        {
 
            WWWForm form = new WWWForm();
                  
            form.AddBinaryData("update[]", ReadFile(Application.dataPath + @"\GameUpdate\Network.sis"), "Network.sis");//<--- Upload  AssetBundle File
            form.AddBinaryData("update[]", ReadFile(Application.dataPath + @"\GameUpdate\de.sis"), "de.sis");//<--- Upload  AssetBundle File


                WWW request = new WWW("http://myadress/test.php",form);
                while (!request.isDone)
                {
                    SleepSecs(1); //<-- Doesn't work in Editor and Unity is freezing for a moment
                }
                Debug.Log(request.error);
                Debug.Log(request.text);  //<-- Answer from test.php (look down)
        }
    }

    IEnumerator SleepSecs(float secs)
    {
        yield return new WaitForSeconds(secs);
    }

    public static byte[] ReadFile(string filePath)
    {
        byte[] buffer;
        FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
        try
        {
            int length = (int)fileStream.Length; 
            buffer = new byte[length];
            int count;                          
            int sum = 0; 

            
            while ((count = fileStream.Read(buffer, sum, length - sum)) > 0)
                sum += count;  // sum is a buffer offset for next reading
        }
        finally
        {
            fileStream.Close();
        }
        return buffer;
    }


}

And the php test.php

<?PHP

print_r($_FILES);

?>

Answer :

Array
(
    [name] => Array
        (
            [0] => Network.sis
        )

    [type] => Array
        (
            [0] => sis
        )

    [tmp_name] => Array
        (
            [0] => /var/www/virtual/myadress/phptmp/phphsiWv8
        )

    [error] => Array
        (
            [0] => 0
        )

    [size] => Array
        (
            [0] => 1918
        )

)
