Proper syntax for text field (less garbled)

I'm almost there... if someone could please help me :slight_smile:

OK, if I have this in my .html.erb:

<%= button_to "Add to Cart" , :action => 'add_to_cart', :id => item, :amount => 3 %>

I get proper behavior. But I'm trying to figure out how to wire up a text field for :amount

<%= text_field_tag '$', @amount %></p> <%= button_to "Add to Cart" , :action => 'add_to_cart', :id => item, :amount => @amount %>

Doesn't work. Does anybody have an idea of what would?

add_to_cart is now working with

  def add_to_cart     item = Item.find( params[ :id ] )     @cart = find_cart     @cart.add_item( item, params[ :amount ] )   end

Can anyone help??

Many TIA, Craig

You need a form. What button_to does is create a form containing just a button, whereas you need a form containing both the textfield and the submit button
