Dispatch event and Observer in magento

Dispatch event and Observer in magento

If you want to override magento Core functionality , You should use dispatch event. Magento gives us facility of dispatch event and this is called one type of Hook.

Here is the syntax of dispatch event :

Mage::dispatchEvent('event_name', array('data' => $data));

In this event we use $observer variable, Suppose we want to save order data into

other database or other table so what we do for that. Magento has a default

dispatch event named "checkout_submit_all_after". Now create one module to

override the code...

Put below code in your module confix.xml file

<global>

<events>
    <checkout_submit_all_after>

         <observers>
              <chand_phpcoder_model_observer>
                   <type>singleton</type>
                   <class>Chand_Phpcoder_Model_Observer</class>

                   <method>saveOrder</method>
              </chand_phpcoder_model_observer>

         </observers>
    </checkout_submit_all_after>

</events>

</global>

Now open your Model and put Observer.php file and write below code :

<?php

class Chand_Phpcoder_Model_Observer {
    public function saveOrder($observer)
    {
      Mage::log('Your Statement');
    }
}
?>
That's it... Enjoy Chandresh rana's Coding.... :)
