I’ve been trying to create a page like this:  
[http://img175.imageshack.us/img175/7323/mephistohw0.png](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

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!
