#pat-upload

A pattern that creates a drop area for uploading multiple files.

Based on DropzoneJS.

##demo

To view a demo of how this pattern works, clone the repository:

git clone https://github.com/Patternslib/pat-upload.git

The run the Makefile:

make

And then in your browser open: http://localhost:4001

Form protection

Some systems allow to pass a authentication token to protect against CSRF attacks. You can do this with pat-upload by adding a URL parameter, even if the upload happens in a POST request. This is a valid practice, see: https://stackoverflow.com/a/1592446/1337474

For example, for a plone.protect style token, do:

 <fieldset class="pat-upload"
data-pat-upload="url: https://example.com/upload?_authenticator=TOKEN"
>
</fieldset>
