Pure ASP.NET Upload - Upload to variable folder

Upload to variable folder

In this tutorial we will explain how to do a file upload to a folder that is chosen dynamically. This means that your folder name can vary. An example of this is when you want to have the user name as a folder name.

How to do it

To make the file upload to a variable folder, you need to:

1. Start with basic upload page

   Start with an upload page with the Pure ASP.NET Upload in place. If you haven't done it yet, go through the Simple file upload tutorial.

2. Open the Pure ASP.NET Upload dialog

   Select the Pure ASP.NET Upload dialog by opening the Server Behaviors Panel. Select DMXzone - Pure ASP.NET Upload.



3. Choose the variable folder

When you need to use a variable folder, you can enter any expression you want in the Upload Folder field. For example if I have a Session variable that has the user login in it, I could write:

"Upload/".$HTTP_SESSION_VARS['Login']

this will create a new directory for every user that tries to upload! Non existent folders will be auto-created so this is really powerful! You only need to setup the security on the main Upload folder, for more info how to do this read the Setting the folder security on your server tutorial.



You might also check the Prefix With Full Path option. This option will store the full path in your database (if you are saving the filename in a database). So it will be easy to retrieve a list of all files later on.

4. Save and done

Save your page and upload it to your server, and you are done! Go to your website and test it - you should be able to upload any file to a dynamic folder.
