Lots of requests but not many answers on this topic. Here is how you do  
it:

FORM:

\<% for i in 1..6 %\> \<% end %\>

| Title | " name="\<%= "picture[#{i}][title]" %\>" size="30" type="text" /\> |
| Image | " name="\<%= "picture[#{i}][image\_data\_temp]" %\>" type="hidden" /\> " name="\<%= "picture[#{i}][image\_data]" %\>" size="30" type="file" /\> |
|   
 |

CONTROLLER:  
params[:picture].each { |attr, value|  
unless value[:image\_data].blank?  
new\_image = Image.new  
new\_image.person\_id = session[:person\_id]  
new\_image.title = value[:title]  
new\_image.image = value[:image\_data]  
new\_image.save  
end  
}

MODEL:  
class Image \< ActiveRecord::Base

file\_column :image

end

Hi Taylor,

how do you handle and display the errormessages, e.g: the 1st and 3rd  
file don´t match filesize or filetype etc out of a total of 4 ??

Best regards  
matthi

ps: i have also multiple\_file upload running, even my code is different,  
the error\_message\_stuff should/could be handled the same
