How to create an observer before save billing & shipping address on checkout page in magento?

So for that I will fire an event.

Answer 1

You can use the standard controller action events: 'controller_action_predispatch_' . $this->getFullActionName()

In the case of the saveBilling action the event is controller_action_predispatch_checkout_onepage_saveBilling

and for saveShipping is controller_action_predispatch_checkout_onepage_saveShiping.

You can access the values sent to that action by

Mage::app()->getRequest()->getPost();

Answer 2

All you have to add function using this observer

sales_order_place_before

When Customer click on place order this observer triggered before placing the order.

Hope this will helps:)

Answer 3

Try this

<events>
  <customer_address_save_before>
    <observers>
      <easylife_model_observer>
        <type>model</type>
        <class>Easylife_Validation_Model_Observer</class>
        <method>customAddressSa‌​veBefore</method>
      </easylife_model_observer>
    </observers>
  </customer_address_save_before>
</events>

sorry for correction. Now it's correct yesterday I post wrong?
