Pure PHP Upload Tutorials - Restrict upload file types
Restricting upload file types
In this tutorial we will explain how to only allow specific files to be uploaded.
You can restrict unwanted file types from being uploaded (depending on their
extension).



How to do it
To make the file upload with restricted file types, you need to:
- Start with basic upload page
Start with an upload page where you have Pure PHP Upload on it. If
you haven't done it yet, go through the Simple
file upload tutorial.
- Open the Pure PHP Upload dialog
Select the Pure PHP Upload dialog by opening the Server Behaviors
Panel. Select DMXzone - Pure PHP Upload.

- Select the Allowed Extensions
When you need to restrict the uploaded files to specific number of
extensions, you need to select the Allowed Extensions field.
First choose the extensions type. All means no restriction, Images
Only will fill in the most common image extensions and Custom will
allow you to enter your own comma separated list of allowed extensions.
In this example we've chosen to only allow our users to upload Images
Only.

So now you choose for example to upload Images Only.
- 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 only be able to upload images now.
