hidden fields

Similar (but different) to another thread called 'accessing post array',
I have some records that I need sent via an array but I don't want to
use a text field but rather a hidden field because I don't want them
tampered with.

Simplifying my form quite a bit...

  <% form_for :supptrans, @supptrans, :url => { :action =>
"print_checks" } do |form| %>
<table cellpadding="3" cellspacing="3" border="0" width="100%">
...
  <tbody>
...
    <tr valign="top" class="ListLine<%= odd_or_even %>">
      <td><%=h (check_due.supplier.suppname) %></td>
      <td><%=h (check_due.suppreference) %></td>
  <%= form.hidden_field :paid_invoices, {:value => check_due.id} %>
  <%= text_field 'check_number', 'check_number', :size => '8' %>
  <%= submit_tag 'Print Checks' %>
<% end %>

where I need the form to submit the starting check number but I also
need the check_due.id in an array so I know which checks are going to be
printed.

this
  <%= form.hidden_field :paid_invoices, {:value => check_due.id} %>
is only the latest attempt but I have tried many things including...
  <%= hidden_field :paid_invoices, "paid_invoices[]", {:value =>
check_due.id} %>

but none of them will give me an array of 'paid_invoices' that I will be
able to parse later similar to
  <%= check_box_tag 'paid_invoices', 'paid_invoices[]', false %>
would give me

Is there a way to popular an array of 'hidden_field' elements for
posting?

Then keep that info server-side.

You could go with active_record_store for your session data.
