Magento 1.9 – Paypal Standard Order Status Shows Pending Payment

If you do not want to have Paypal Express Checkout button displayed in the shopping cart you can turn it off in the Basic settings of Express Checkout. This will allow to have PayPal mark available on the Payments step only along with Pro. In this case customer will be forced to fill in all the fields before get to the payment page. Also in 1.9 you have an ability to skip order review page for Express and make checkout process even more shorter. See this link.

Pro can be activated with Express only, besides Express API is better than Standard since does not rely on IPN - able to process payment and create order at the same time.

If you are using Paypal IPN check the following code

class : Mage_Paypal_Model_Ipn

     /**
     * Process regular IPN notifications
     */
    protected function _registerTransaction()
    {
        try {
            // Handle payment_status
            $paymentStatus = $this->_filterPaymentStatus($this->_request['payment_status']);
            switch ($paymentStatus) {
                // paid
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_COMPLETED:
                    $this->_registerPaymentCapture(true);
                    break;

                // the holded payment was denied on paypal side
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_DENIED:
                    $this->_registerPaymentDenial();
                    break;

                // customer attempted to pay via bank account, but failed
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_FAILED:
                    // cancel order
                    $this->_registerPaymentFailure();
                    break;

                // payment was obtained, but money were not captured yet
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_PENDING:
                    $this->_registerPaymentPending();
                    break;

                case Mage_Paypal_Model_Info::PAYMENTSTATUS_PROCESSED:
                    $this->_registerMasspaymentsSuccess();
                    break;

                case Mage_Paypal_Model_Info::PAYMENTSTATUS_REVERSED:// break is intentionally omitted
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_UNREVERSED:
                    $this->_registerPaymentReversal();
                    break;

                case Mage_Paypal_Model_Info::PAYMENTSTATUS_REFUNDED:
                    $this->_registerPaymentRefund();
                    break;

                // authorization expire/void
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_EXPIRED: // break is intentionally omitted
                case Mage_Paypal_Model_Info::PAYMENTSTATUS_VOIDED:
                    $this->_registerPaymentVoid();
                    break;

                default:
                    throw new Exception("Cannot handle payment status '{$paymentStatus}'.");
            }
        } catch (Mage_Core_Exception $e) {
            $comment = $this->_createIpnComment(Mage::helper('paypal')->__('Note: %s', $e->getMessage()), true);
            $comment->save();
            throw $e;
        }
    }
