get order address when sending invoice - php

Question

I'm overriding the Mage_Core_Model_Email_Template-class send()-method in order to send an SMS to the customer at the same time as the email is being sent.
What I'm not sure how to do is to get the customer information connected to the order. Usally all the information is inserted in the email template as variables, but I need to access it in PHP from the mentioned class. And it needs to be the customer information, like name, phone and so on from the order object since orders may be placed without registering on the webshop (also to get the correct phonenumber for the specific order).
Any help would be highly appreciated, I have no idea how to even get the orderId from within this class. Also would like to be able to list these customer specific field-names in an admin-view for choosing the telephone field as the source of SMS recipient, so if there's a way to output all the customer specific field-names connected to orders that would be great too.
Thanks in advance! :)

Answer 1

I still say that event-capture is the practical way, but I respect your point of view. So in the other way, the sendMail method of Mage_Sales_Model_Order_Invice contains the "order" object as template parameter:
$mailer->setTemplateParams(array(
'order' => $order,
'invoice' => $this,
'comment' => $comment,
'billing' => $order->getBillingAddress(),
'payment_html' => $paymentBlockHtml
)
);
The mailer object is an instance of Mage_Core_Model_Email_Template_Mailer class, i recommend to overwrite the send method of this class, and then you can access the data you need via method $this->getTemplateParams(), and the address and customer information from the order object, as you can find in my previous answer.

Magento has an event-driven architecture, so in issues like this it is much better to create an Observer to catch an event. How to create observers This event in your case is "sales_order_invoice_register". For this you need in your module's config eg. app/code/local/Stack/Test/etc/config.xml:
<events>
<sales_order_invoice_register>
<observers>
<stacktest>
<type>singleton</type>
<class>stacktest/observer</class>
<method>sendSMS</method>
</stacktest>
</observers>
</sales_order_invoice_register>
</events>
And in you Observer, which is app/code/local/Stack/Test/Model/Observer.php:
class Stack_Test_Model_Observer extends Mage_Core_Model_Observer
{
public function sendSMS($observer)
{
#get the customer
$order = $observer->getEvent()->getOrder();
Mage::log($order->getBillingAddress());
Mage::log($order->getShippingAddress())
Mage::log($order->getCustomerEmail());
Mage::log($order->getCustomerFirstname());
Mage::log($order->getCustomerLastname());
...
You can get all data like this, and send the sms directly from the Observer class, no need to override the send method.

If you are overriding the send function you can use its parameter $variables, an array, which contains, among other data, an order object ($variables['order']). This is true for the order email, invoice, shipment, and creditmemo emails.
This make my suggestion of "registering an order" redundant.
The first thing that comes to mind is to capture an event dispatched when an order is placed and save the order object from the event into the Magento registry. Then you can fetch that registry entry from your overridden send function. This should work assuming the SMS is sent during the request that submits the order, and not later, like when the SMS are dispatched from a queue processor.
So this idea can be implemented like this:
Register the observer
<config>
<!-- -->
<global>
<!-- -->
<events>
<sales_order_place_after>
<observers>
<yournodename>
<class>YourPackage_YourModule_Model_Observer</class>
<method>registerOrder</method>
</yournodename>
</observers>
</sales_order_place_after>
</events>
<!-- -->
</global>
<!-- -->
</config>
Implement the observer
class YourPackage_YourModule_Model_Observer
{
public function registerOrder(Varien_Event_Observer $observer)
{
$order = $observer->getEvent()->getOrder();
Mage::register('currentOrder', $order);
}
}
Access the registry entry:
public function send()
{
$order = Mage::registry('currentOrder');
if ($order instanceof Mage_Sales_Model_Order) {
$address = $order->getBillingAddress();
if (!$order->getCustomerId()) {
//guest order
} else {
$customer = Mage::getModel('customer/customer')
->load($order->getCustomerId());
}
}
}
