Data from forms

Hi,

if I have a test_form with lots of text_field s, how do
I save as an array?
<%= form_tag %>
<%= text_field ‘test_form’, ‘text_field_1’ %>
<%= text_field ‘test_form’, ‘text_field_2’ %>
<%= text_field ‘test_form’, ‘text_field_3’ %>

    <%= submit_tag ... %>
    <%= end_form_tag %>

Best,
Ram.
