how to change magento order status programatically?

Question

I'm using magento 1.9 and I have to change the order status from shipped to delivered, both status having the same state "complete"

How can I able to change this?

I have tried following code

$order = Mage::getModel("sales/order")->loadByIncrementId(100000123);
$order->setData("state", "complete");
$order->setStatus("delivered");
$history = $order->addStatusHistoryComment('A ser executada a rotina de recarga.', false);
$history->setIsCustomerNotified(false);
$order->save();

But it gives

PHP Fatal error: Call to a member function getMethodInstance() on boolean in /app/code/core/Mage/Payment/Model/Observer.php on line 46

• Avinash Borse: self resolved. $order = Mage::getModel('sales/order')->load($orderId); $order->addStatusHistoryComment('','delivered') ->setIsVisibleOnFront(false) ->setIsCustomerNotified(false); $order->save()
• Rat: I have tried above code , state and status field updated. But we get the error message as "Item (Mage_Sales_Model_Order) with the same id "325" already exist" require_once "app/Mage.php"; umask(0); Mage::app('default'); $order = Mage::getModel('sales/order')->load(403); $order->setData('state', "complete"); $order->setStatus("complete"); $order->save();

When I have got and error "The Order State "complete" must not be set manually." I found the solution here https://stackoverflow.com/questions/18711176/how-to-set-order-status-as-complete-in-magento

you can change order status as below:

$orderId = YOUR_ORDER_ID;
$order = Mage::getModel('sales/order')->load($orderId);
$orderIncrementId = YOUR_ORDER_INCREMENT_ID;
$order = Mage::getModel('sales/order')->loadByIncrementId($orderIncrementId);
/**
 * change order status to 'Completed'
 */
$order->setState(Mage_Sales_Model_Order::STATE_COMPLETE, true)->save();
/**
 * change order status to 'Pending'
 */
$order->setState(Mage_Sales_Model_Order::STATE_NEW, true)->save();
/**
 * change order status to 'Pending Paypal'
 */
$order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, true)->save();
/**
 * change order status to 'Processing'
 */
$order->setState(Mage_Sales_Model_Order::STATE_PROCESSING, true)->save();
/**
 * change order status to 'Completed'
 */
$order->setState(Mage_Sales_Model_Order::STATE_COMPLETE, true)->save();
/**
 * change order status to 'Closed'
 */
$order->setState(Mage_Sales_Model_Order::STATE_CLOSED, true)->save();
/**
 * change order status to 'Canceled'
 */
$order->setState(Mage_Sales_Model_Order::STATE_CANCELED, true)->save();
/**
 * change order status to 'Holded'
 */
$order->setState(Mage_Sales_Model_Order::STATE_HOLDED, true)->save();

• Avinash Borse: I tried this but it gives error "The Order State "complete" must not be set manually." I want to change status not state of order.
• Alam Zaib: $order->setData('state', Mage_Sales_Model_Order::STATE_COMPLETE); $order->setStatus(Mage_Sales_Model_Order::STATE_COMPLETE); $history = $order->addStatusHistoryComment('Order was set to Complete by our automation tool.', false); $order->save()
