Rails - Mar 2006 - How to use variables inside rhtml??

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'',''product_id+@i.to_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.

Rails has build in support for this.

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.
