#payment_service_for(order, account, options = {}) {|service| ... } ⇒ Object

This helper allows the usage of different payment integrations through a single form helper. Payment integrations are the type of service where the user is redirected to the secure site of the service, like Paypal or Chronopay.

The helper creates a scope around a payment service helper which provides the specific mapping for that service.

<% payment_service_for 1000, '[email protected]',
                             :amount => 50.00, 
                             :currency => 'CAD', 
                             :service => :paypal, 
                             :html => { :id => 'payment-form' } do |service| %>

  <% service.customer :first_name => 'Cody',
                     :last_name => 'Fauser',
                     :phone => '(555)555-5555',
                     :email => '[email protected]' %>

  <% service.billing_address :city => 'Ottawa',
                            :address1 => '21 Snowy Brook Lane',
                            :address2 => 'Apt. 36',
                            :state => 'ON',
                            :country => 'CA',
                            :zip => 'K1J1E5' %>

  <% service.invoice '#1000' %>
  <% service.shipping '0.00' %>
  <% service.tax '0.00' %>

  <% service.notify_url url_for(:only_path => false, :action => 'notify') %>
  <% service.return_url url_for(:only_path => false, :action => 'done') %>
  <% service.cancel_return_url 'http://mystore.com' %>
<% end %>
