Magento registry is a great way of sharing information anywhere in your Magento store as they are static function.In other words Magento registry implies creation of new global variables which can be accessed anywhere within your Magento store. I have been wondering always,where is all the registry data stored in Magento ? I know that even singleton objects are stored in the registry. And registry is just a static array variable of the Mage class. Is registry different for different users ? I mean is it created on a per-user (per HTTP request) basis?

Each state can have one or several statuses and a status can have only one state. By default, statuses and states have often the same name, that is why it is a little confusing. Here is the list of statuses and states available by default. $order = Mage::getModel('sales/order')->loadByIncrementId('100000001'); $state = 'processing'; $status = 'Payment After Cancelled'; $comment = 'Changing state to Processing and status to Payment After Cancelled '; $isCustomerNotified = false; $order->setState($state, $status, $comment, $isCustomerNotified); $order->save(); $status can also take false value in order to only set order state, or true value for setting status by taking first status associated to this state. You can now adjust as you wish your order workflow in Magento.
