link_to

I am trying to use an encrypted request to PayPal using my own submit button link I googled a little but, but could not find a clear & neat solution, so I ended writing this :

== Rails 2.3.8 script code ==== ...     <% form_tag APP_CONFIG[:paypal_url], {:id => 'form_paypal'} do %>       <%= hidden_field_tag :cmd, "_s-xclick" %>       <%= hidden_field_tag :encrypted, @cart.paypal_encrypted(root_url, payment_notifications_url(:secret => APP_CONFIG[:paypal_secret])) %>       <p><%= link_to_function "OK", "$('form_paypal').submit()" , :class => 'buy' %></p>     <% end %> ...

[SOLVED] I realized that I was using jQuery and not Prototype anymore .. so the link_to function was not right and should have been written with the correct jQuery id # : ('#form_paypal').submit()

<%= link_to_function "OK", "$('#form_paypal').submit()" , :class => 'buy' %>
