add cart contents to linkpoint payment form field

[mrjones]

I'm using the LinkPoint Basic Payment contribution, and need to add a few hidden fields to pass to LinkPoint, for when their server times out and doesn't redirect my customers back to checkout_process.php. I want to pass the cart contents and order number, but can't figure out how to add it in. Current code example:

 

    function process_button() {

     global $HTTP_SERVER_VARS, $CardNumber, $order, $customer_id;



     $process_button_string = tep_draw_hidden_field('cardnumber', $this->cc_card_number) .

               tep_draw_hidden_field('expmonth', $this->cc_expiry_month) .

   tep_draw_hidden_field('expyear', $this->cc_expiry_year) .

   //NEED TO GET: cctype

   tep_draw_hidden_field('cctype', $this->cc_type) .

               tep_draw_hidden_field('chargetotal', number_format($order->info['total'], 2)) .

               // NEED TO GET : subtotal tax & shipping charges

   // number_format($total_cost + $total_tax + $shipping_cost, 2)

   //tep_draw_hidden_field('shipping', number_format($shipping_cost,2)) .

   //tep_draw_hidden_field('tax', number_format($total_tax,2)) .

   tep_draw_hidden_field('customerid', $customer_id) .

   tep_draw_hidden_field('userid', $customer_id) .

               tep_draw_hidden_field('x_Email_Customer', (MODULE_PAYMENT_LINKPOINTBASIC_EMAIL == '1'? 'TRUE': 'FALSE')) .

               tep_draw_hidden_field('x_Email_Merchant', (MODULE_PAYMENT_LINKPOINTBASIC_EMAIL_MERCHANT == '1'? 'TRUE': 'FALSE')) .

               tep_draw_hidden_field('bname', $order->billing['firstname'] . ' ' . $order->billing['lastname']) .

               tep_draw_hidden_field('baddr1', $order->customer['street_address']) .

   tep_draw_hidden_field('baddr2', $order->delivery['suburb']) .

               tep_draw_hidden_field('bcity', $order->customer['city']) .

 

Where is says userid above, I want to pass the order number and not the customer number, and then I'd like to pass the cart contents in another field. Any ideas how I can do this? Do I have to add extra variables to the global line at the top?

 

Thanks!
