Write timestamp for addressbook change

Question

1. Login to the website frontend in a customer account.

Click on "Account information" and edit some information (firstname, lastname, ...). Click on the save button. Now login to the magento backend and click on customers -> manage customers. Now you see the grid with the correct "updated_at" timestamp.

2. Login to the website frontend again. Click on "Account information"

And now click on "Addressbook" and edit some information. Click on the save button. Now go to the magento backend and click on customers -> manage customers. Updated_at is not changed.

Question: How can we set new updated_at timestamp for the address book also?

Address is its own table and has its own updated_at field. If i want to see the timestamp of customer updated when address is updated, i have to an observer for customer_save_after update the timestamp of customer there?

Can you tell me how we can setup an observer for customer_save_after update for the timestamp? In which file i have to add the code?

Thank you and best wishes from germany

Take care I have not tested that code but the idea is here.

In your config.xml you have to add observer declaration :
<customer_address_save_after> <observers> <update_customer_after_address_save> <class>module/observer</class> <method>updateCustomerAfterAddressSave</method> </update_customer_after_address_save> </observers> </customer_address_save_after>

Then in your Observer.php file add the function:

public function updateCustomerAfterAddressSave(Varien_Event_Observer $observer){
/** @var Mage_Customer_Model_Address $_address */
$_address = $observer->getCustomerAddress();
if (!$_address->hasDataChanges()) {
    return $this;
}

/** @var Mage_Customer_Model_Customer $_customer */
$_customer = $_address->getCustomer();
$_customer->setUpdatedAt(Varien_Date::now())
    ->save();}

---

Magento have "dynamic" observers launched before/after save/load entities in Mage_Core_Model_Abstract in these functions:
- _beforeSave()
- _afterSave()
- _beforeLoad()
- _afterLoad()

Magento use $_eventPrefix variable to make it dynamic. The Customer_Address one is in Mage_Customer_Model_Address_Abstract. With that you can find the observer hook customer_address_save_after.

Here is an example that explain how to create an extension with an observer : https://magento.stackexchange.com/a/41280/33619
Note that in your case you have to change the observer node from <adminhtml> to <frontend> in the config.xml

Filename Observer.php in folder /app/code/local/Easylife/Meta/Model

public function autoMetaDescription(Varien_Event_Observer $observer){
/** @var Mage_Customer_Model_Address $_address */
$_address = $observer->getCustomerAddress();
if (!$_address->hasDataChanges()) {
    return $this;
}

/** @var Mage_Customer_Model_Customer $_customer */
$_customer = $_address->getCustomer();
$_customer->setUpdatedAt(Varien_Date::now())
    ->save();}
