Handling Multiple Uploads on One Page

I've been trying to create a page like this:
http://img175.imageshack.us/img175/7323/mephistohw0.png
I was able to browse through the Mephisto source and figure out the
JavaScript to add upload fields dynamically, but I cannot figure out
how to process an unlimited amount of uploads in the controller.

In the Mephisto source it seems that each upload is stored in an
array, however, I cannot recreate this in my application. Can anyone
explain to me how to pull this off the DRY way?

You have to give your html tag a tag like 'apples[]'.

<%= form_remote_tag :update => @html_division, :url => {:action=>
'proceed'} %>

<%= file_field_tag "apples[]" %>
<%= file_field_tag "apples[]" %>
<%= file_field_tag "apples[]" %>
<%= file_field_tag "apples[]" %>
<%= file_field_tag "apples[]" %>
<%= file_field_tag "apples[]" %>

<%= submit_tag "Send apples" %>
<%= end_form_tag %>

This way, your controller will receive an array.

params[:apples].each do |an_apple|
    do_something_with_the_apple an_apple
end

yeah, i had this exact problem. so i wrote a tutorial after going
through mephisto line for line with a ruby book. share with me the
javascript, please.

Thanks for the help everyone, I was able to use Sébastien's to handle
the uploads, and Plewizard's tutorial helped on processing it.

Thanks again!
