get customer infos on success.phtml

Question

I try to get customer infos on success.phtml. I try it as guest and as logged in user.

First of all I get an order object.

$orderId = $this->getOrderId();
$order = Mage::getModel('sales/order')->load($orderId);

Or for debugging on a separate page, with an order ID:

$order = Mage::getModel('sales/order')->load('300000040');

Then I try to get the name:

echo $order->getCustomerName();

that gives me: Gast (guest in englisch). No matter if I am logged in or not.

Then I try to get the email:

$billingAdress = $order->getBillingAddress();
echo "!!".print_r($billingAdress, 1); //nothing! empty
$customerEmail = $billingAdress->getEmail(); //Fatal error: Call to a member function getEmail() on a non-object....

It seems like the order object is wrong, I can't get the total:

echo $order->getGrandTotal(); //empty

Magento Version 1.7.0.2

Does anyone see my mistake?

Answer 1

This

$order = Mage::getModel('sales/order')->load('300000040');

Should be

$order = Mage::getModel('sales/order')->loadByIncrementId('300000040');

Use load only when you have the table primary key.
