Question

I need use button_tag instead submit_tag on a form to add icon with style http://twitter.github.com/bootstrap/base-css.html#buttons.

<%= simple_form_for(bla..........bla......)) do  %>
 <%= button_tag t('.sent_to_trash'), :class => "btn btn-small btn-primary disabled", :id => "trash_button", do %>
   <i class="icon-trash icon-white"></i>
   <%= t('.sent_to_trash') %>
 <% end %>
<% end %>

The question is I can not receive the params[:commit] with button_tag, however with submit_tag is working fine and I receive correctly params[:commit] on my action controller.

How can I fix this problem?

Thank you very much!

Html element button works with :name and :value params, so you have to explicitly define these, e.g.

= button_tag(:name => "commit", :value => "my_button") do
  = "Press me!"

then you get params[:commit] = "my_button" after form submit.

Note: You should specify :type attribute too, because different browsers use different default types for the <button> element (:type => "submit")
