This is a multi file upload widget. That does not require adding multiple file input fields. It requires jQuery.MultiUpload (http://www.fyneworks.com/jquery/multiple-file-upload/)

Nice and useful widget, just what I was going to write myself. You saved me the trouble!

Why do you append "[]" to the end of the name though?

Hi! I'm new to django, can you tell me how to use this snippet? I tried creating new form with MultiFileInput as a field but everytime I get error that no files were uploaded..

just use HTML5's 'multiple' form attribute,no need for js:

<form action='#' method='post' enctype='multipart/form-data'> <input name='uploads[]' type=file multiple> <input type='submit'> </form>

That should fix it
