paypaldp.php: Invalid class variable

[lat9]

For whatever reason, I was scouring the payment modules to see what shopping_cart class constructs are used and I came across the following in /includes/modules/payment/paypaldp.php:

 function get3DSecureLookupResponse($lookup_data_array) {
    // Set some defaults
    if (!isset($lookup_data_array['order_desc']) || $lookup_data_array['order_desc'] == '') $lookup_data_array['order_desc'] = 'Zen Cart(R) Transaction';
    if (!isset($lookup_data_array['order_number']) || $lookup_data_array['order_number'] == '') $lookup_data_array['order_number'] = zen_session_id();
    // format the card expiration
    $lookup_data_array['cc3d_exp_year'] = (strlen($lookup_data_array['cc3d_exp_year']) == 2 ? '20' : '') . $lookup_data_array['cc3d_exp_year'];
    // get the ISO 4217 currency
    $iso_currency = $this->getISOCurrency($lookup_data_array['currency']);
    // format the transaction amounts
    $raw_amount = $this->formatRawAmount($lookup_data_array['txn_amount'], $iso_currency);
    // determine the appropriate product code for submission
    $prodCode = FALSE;
    if (isset($_SESSION['cart'])) {
      if ($_SESSION['cart']->get_cart_type == 'virtual') {
        $prodCode = 'DIG';
      } else {
        $prodCode = 'PHY';
      }
    }

The variable highlighted in red doesn't exist in the shopping_cart class; the line probably should read:

 if ($_SESSION['cart']->get_content_type() == 'virtual') {
