I'm using observer method sales_order_save_before to do some operations based on order state

   $order = $observer->getEvent()->getOrder();
   $initialState = $order->getOrigData('state');
   $newState = $order->getData('state');
   if($initialState != $newState && $newState == 'processing'){
    // Do some operation          
    }
   if($initialState != $newState && $newState == 'complete'){
    // Do some operation          
    }

First validation is working fine whereas in second if loop both the conditions are not being true at the same time.

I did some modifications in order and digged dipper into its status. What I see is when first time order is placed it's status and state is processing . When order is shipped and invoiced in admin it's status becomes complete but state still remains processing. When the status is complete and I write a comment on this order then it's state becomes complete due to which second if loop is not working.

How I can validate the loop when the order state becomes complete ? (initialState should be different than newState).

The problem is that the state is changed after the sales_order_save_before event has been dispatched.

Take a look at Mage_Sales_Model_Order:

/**
 * Processing object before save data
 *
 * @return Mage_Core_Model_Abstract
 */
protected function _beforeSave()
{
    parent::_beforeSave();           <-- here the event is dispatched
    $this->_checkState();            <-- here the new state is set based on current
    ...                                  state and other conditions
}

Since there is no other event fired before the actual saving, your best bet is to observe sales_order_save_after and save the order a second time if you must.

  • But if I observe sales_order_save_after, $order->getOrigData('state'); will not give proper result so I won't be able to do a proper comparison, right? – amitshree Jul 22 '15 at 19:01

    I don't think so. orig_data should only be reset after load. But if I'm wrong, you still can back it up in a sales_order_save_before observer: $this->_origData = $order->getOrigData(); and read it in the sales_order_save_after observer (assuming both are in the same class and registered as singleton) – Fabian Schmengler Jul 22 '15 at 19:07
  • That works :) Though I would like to know how I can back it up in sales_order_save_before and use in sales_order_save_after . Should I dispatch sales_order_save_after method inside sales_order_save_before with backed parameter? Somewhere I read, I can also use registry in this case. – amitshree Jul 22 '15 at 20:10

    No need for the registry. As hinted above, by default observers are singletons and you will implement both observer methods in the same class. So you can simply add a property to the observer. – Fabian Schmengler Jul 22 '15 at 20:51
