I have added a virtual product on my magento website. I wanted to disable the cod option for this product. I made some changes and then that particular product didn't showed COD option as a payment method. But later on I discovered that the product showed error while placing the order and didn't get redirected to the payement gateway page. It is showing these set of errors while placing order.

The first error while placing order

The second error if I refresh the above page

I don't remember the earlier changes I made. Need help

You have problem with validation in this method:

public function getFormFields() {

    $billing = $this->getOrder()->getBillingAddress();
    $shipping = $this->getOrder()->getShippingAddress();
    $addr_entity_id = $shipping->getCustomerAddressId();
    $shippingaddress = Mage::getModel('sales/order_address');
    $shippingaddress->load($addr_entity_id);
    $shipaddgetdat = $shippingaddress->getData();

As you are using the virtual product, your order has no shipping address. Before use of a shipping address, try to check whether the order is virtual (if this is so - use the billing address instead of shipping):

public function getFormFields() {

    $billing = $this->getOrder()->getBillingAddress();
    if ($this->getOrder()->getIsVirtual()) {
        $shipping = $billing;
    } else {
        $shipping = $this->getOrder()->getShippingAddress();
    }
    $addr_entity_id = $shipping->getCustomerAddressId();
    $shippingaddress = Mage::getModel('sales/order_address');
    $shippingaddress->load($addr_entity_id);
    $shipaddgetdat = $shippingaddress->getData();

This is a "hot fix". You should not use the shipping address in a case when the order is virtual. Your code needs fuller refactoring.

  • Its working great, thankyou for the help. Also, how to refactor the code, since I am afraid of messing around with code. – Mohammad Anas Siddiquei Sep 4 '16 at 9:52
  • @MohammadAnasSiddiquei You need to divide your big method into small parts (methods) and at the beginning you should validate the shipping address availability (whether the order is virtual). It is necessary to work with the abstract address, but not the specific address type. If my answer was helpful for you, plaese, accept it as solution. – Siarhey Uchukhlebau Sep 4 '16 at 10:06
  • Yes, your solution is working fine now. Thankyou!! – Mohammad Anas Siddiquei Sep 8 '16 at 17:59
