Hello DMXZone,

I think you really didn't test this extension very well. It still gives me a lot of headaches.

I did follow the tutorial and I didn't get uploaded a image. So I looked in the code with IE developerstool and find some interesting things.

I have to modify this New File.asp shown as below. When sync starts there are several errors with relative and absolute paths.

<!--#include virtual="/YourWebsite/dmxConnectLib/dmxConnect.asp" -->
<!--#include file="../../dmxConnectLib/dmxConnect.asp" -->

<script runat="server" language="jscript">

var app = require('lib/app');

app.define( //<<<'JSON'
"meta": {
"options": {
"linkedFile": "/z-upload.asp",
"linkedForm": "formUpload"
"$_POST": [
"name": "fileField",
"type": "object",
"sub": [
"name": "isFile",
"type": "var"
"name": "name",
"type": "var"
"name": "type",
"type": "var"
"name": "size",
"type": "var"
"name": "error",
"type": "var"
"exec": {
"steps": {
"name": "myFileUpload",
"module": "upload",
"action": "upload",
"options": {
"throwErrors": true,
"fields": "{{$_POST.fileField}}",
change: "path": "/YourWebsite/images"
to: "path": "/images"
"meta": [

When modified I upload all the necessary folders dmxconnect and dmxconnectLib with including files to the server.

Also the files below to the Scriptlibrary folder

So now I am ready for testing uploading a file. with IE developerstool (F12) And it works, Yeah. All files 200 OK

This doesn't work:
Enable the create path option (1) if you want the HTML5 File Upload to create the upload folder, if it doesn't exist on your server

"path": "/images" already created folder
"path": "/images/photo" need to be create subfolder if not exist
I get an 500 error..

So I still have huge problems with this extension.

The upload scripts use temporary folder, which is used to temporarily store the file, until the file upload script writes it into the upload folder.
If no temp folder is set, the script uses the windows temp folder, which on your local machine most probably does not have a write permissions.
This is usually an issue on local user machines, running servers, as they are not properly configured (post size, permissions, etc.) but this is taken care of on the hosting servers.
You can set a folder on your server root or in your site folder, which has write permissions and point to it in the server connect global settings and check if this fixes your issue.

Despite getting a 200 OK still no image is uploaded to the images folder all you mentioned.

Note: PAU3 works fine uploading to images folder.

I assume you just entered "temp" in the temp folder settings?
Where is your temp folder actually located as this path seems to me wrong, unless you do have a temp folder in the "dmxConnect\api" folder?
The path should be relative to your server root, the same format as it is in the Path field.

Please also try leaving the temp folder setting empty to see if your windows temp folder returns an error. Then enter the right path to your temp folder on the server, as explained above.

Error 7 means, that either there is a permissions issue OR you are running out of disk space. If /tmp is size-constrained, an upload could very well fill it up.

1. set "temp" in the temp folder
2. no api folder only contains "New File.asp"

3. leave temp folder empty. I get a 500 error:

I give C:/windows/temp read/write permissions.

Image is uploaded to images folder. But when I click on the uploaded image I get read/write permission problems.

Do I need to fill in absolute path in Temp folder settings or only "temp"

From what i see in your error message it says "Access Denied" which means the Windows Temp folder does not have write permissions.
If you just write "temp" in the temp folder path, it will be relative to your server connect action file, which means it will look for "temp" folder in the "dmxConnect\api" folder.

Your temp folder path should be the same format as your upload folder path is.
If your upload path in the extension UI is: C:\\inetpub\\wwwroot\\gjs\\images
Then your temp folder path should also be: C:\\inetpub\\wwwroot\\temp (if it is in the wwwroot folder)

Or just set proper permissions to your Windows temp folder

Hi Teodor,

It works like you mentioned. File is uploaded to images folder


Confusion under Server Connect is global settngs.

Instead of Temp folder maybe it is better to write absolute path to Temp folder. And maybe to publish in the manual.

Thanks anyway for your support

As i mentioned, if your server is properly configured, you do not need to change it, as the script will use the Windows temp folder.
Absolute paths cannot be used, as parent paths are not allowed on most of the windows servers for security reasons.

I am glad to hear that all works fine now on your local server.

Hi Teodor,

With the path C:\\inetpub\\wwwroot\\temp under global settings everything local works fine.

Now I leave global settings temp empty:

The temp folder under windows has read/write permission.The file is uploaded to the images folder C:\\inetpub\\wwwroot\\gjs\\images but now the file itselfs has read/write permission problems.

How does I fix this with the properly server configuration?

Under Server Connect

Global settings:
Temp folder: <empty>
Script timeout: <empty>

Temp folder under windows has read/write permission

I upload a file which succeed and I want to view the file in the folder C:\inetpub\wwwroot\gjs\images

I won't view because of read/write error:

Also - if you move the file to another location - is it possible to open it?

When doubleclick on the uploaded file in the folder C:\inetpub\wwwroot\gjs\images

Access denied you need read permissions.

When copy/paste outside the folder to my desktop I need to give admin read permissions to the file and then I can open the file.

This is also related to the Windows Temp folder permissions, as the file inherits the temp folder permissions, when copied to your upload folder.
You need to properly set permissions for your user(s) to the Windows temp folder or just use the inetpub temp folder, where you are sure it has the right permissions.

Ok, thats the trick.

read/write permissions to IIS_IUSRS and uploading works fine now and no permission in the images folder.

Thank Teodor
