Adding a new order state and status in magento

Question

I have followed this guide :

http://islamic-posters.aceph.me/post/19049000412/magento-custom-order-state

and created a new order state and status called "delivered" in my admin. Basically these are used to track which shipments are getting delivered and which are returned. As the shipments get delivered I want to mark them as delivered in the system so that I can keep track. This happens after the order has been invoiced and shipped.

Now the problem is when I try to set the state as "delivered" it keeps going back to "complete". How do I fix this ? How do I change the state to delivered after it has been completed.

I am attaching a screenshot of what happens : http://awesomescreenshot.com/0913gf6981

Answer 1

I think that's because the delivered status is set after the order is shipped, which makes the order complete. To remove this behavior, you need to comment or remove this line in app/code/core/Mage/Sales/Model/Order.php:

$this->_setState(self::STATE_COMPLETE, true, '', $userNotification);

You can find it in the function _checkState(), which is called just before the order is saved.

Having said that, it is a big NO-NO to modify core file directly. You have to bear all the risks that come with it.
