how to retrive multiple vaules from a view for a text_field!

Hi,

I have view page which takes all the information like contact''s emails
,
phones no''s etc and saves different tables. I want to save more than
one
email id''s for a particular contact.

view page is something like this..

.
.
Email 1 :
<%= select ''email'', ''email_type'',
%w(Business Personal), :include_blank
=> false %>
<%= text_field
''email'',''email'',:size=>"35",:maxlength=>"80"
%>
<%= radio_button ''email'', ''isprimary'',
''1'' %>Primary
Email 2 :
<%= select ''email'', ''email_type'',
%w(Business Personal), :include_blank
=> false %>
<%= text_field
''email'',''email'',:size=>"35",:maxlength=>"80"
%>
<%= radio_button ''email'', ''isprimary'',
''1'' %>Primary
.
.

Controller is :

def create
      @contact = Contact.new(params[:contact])
      @contact.emails << Email.new(params[:email])
      @contact.phones << Phone.new(params[:phone])
      @contact.addresses << Address.new(params[:address])
      puts "hellooooooo bharati"
      params.inspect
      if @contact.save
         flash[:notice] = "Contact was successfully created."
         redirect_to :action => ''list''
      else
         render :action => ''new''
                  flash[:notice] = "Contact was not created."
      end
   end


Can any one help me how to send more than one email ids to controller..

The key to the second part is how you name the parameters. In
particular parameters ending with a [] are treated as arrays.

Yes . I was able to submit more than one text field values.. but now my 
issue is how do i differentiate radio buttons with the same name.. both 
the radio buttons are getting selected :(.. here is the code

 <% form_for :@contact do |f| %>
             <% @contact.emails.each_with_index do |email, index| %>
             <% fields_for "email[#{index}]", email do |f|
%><tr> <td>
             Email   &nbsp &nbsp;
             <%= f.select :email_type, %w(Business Personal), 
:include_blank => false %>
             <%= f.text_field :email %>
       <%= f.radio_button :isprimary ,''index'' %>Primary
             </td></tr>
              <% end %>
          <% end %>
<% end %>

they''ll be overwriting each other (which isn''t what I thing
you want).
Also shouldn''t the second parameter to radio_button be index and not
''index'' ?

ya. got it. But there exists an issues.. When i select radio button i ll 
get the following error. . "undefined method `values'' for
"1":String"
where as the other values get saved if i do not select radio button.

Also If i enter only one email id the form is not getting saved. 
Controller is as follows.

 def new
   @contact = Contact.new
   2.times  { @contact.emails.build }
 end
 def create
   @contact = Contact.new(params[:contact])
      params[:email].each_value do |email|
      @contact.emails.build(email) unless email.values.all?(&:blank?)
      end
   if @contact.save
   flash[:notice] = "Successfully created new  Contact.!!!!!!!!!"
     redirect_to :action => ''list''
   else
     render :action => ''new''
   end
 end

Where i went wrong?

containing the string 1, which you then try and call values on.
