Hi, I want to use counters in my rhtml page for dynamic naming of my form elements. eg:- for 1st textbox name will be "text1" for 2nd textbox name will be "text2" ....& so on........ But here I want use a counter variable in rHtml file so that I will use for loop for looping througn each set of elements in form & give name to form elements as "element_name"+i (i is counter variable) I tried it with following code but its nt working:- =========== <% @i=0 %> <% for product in @products %> <%= text_field 'product_item','email@example.com_s', :value=>product.id%></td> <%end%> ============ But its not working proper as I m accessing the value of each textbox in controller class as folllows:- ========= for product in @products params[:product_item][:product_id+'i'] next ======== it gives me error like:- "'+' is undefined" How to deal with this?????? Thanx in advance for ur reply. Prash

Use something like: <% @products.each do |@p| %> <%= text_field 'p', .... %> <% end> This will automatically enumerate your fields in your form. In your controller using params[:p] you fetch you an array of the values entered in all the 'p' fields.
