Programmatically Complete An Order

[rayzorMamon]

Guys, can any of you point out how we can "complete" an Order programmatically?  Basically,  create both the order's invoice and shipment.  

I found this code, I would like to know instead if this is the correct way of completing an order:

$order = $this->getOm()->create('Magento\Sales\Model\Order')->load($order_id);
if ($order->getId()) {
    $order->setStatus('complete')->save();
}

Its based on the order cancellation code below:

$order = $this->getOm()->create('Magento\Sales\Model\Order')->load($order_id);
if ($order->getId()) {
    $order->cancel()->save();
}

I am not quite sure how or what the process is to complete an Order.  I also need to add a comment onto the Invoice as well as the shipment for the said order.

How does \Magento\Sales\Model\ResourceModel\Order\Handler\State::check() work? https://mage2.pro/t/1409

Hello rayzorMamon,

According to your example, you want your answer for Magento 1.9.x.

Here is example check it out and let me know if there is any issue.

$order  = Mage::getModel('sales/order')->load($orderId);
			$totalpaid = $order->getGrandTotal();	
			$order->setTotalDue(0);
			
			$orders = Mage::getModel('sales/order_invoice')->getCollection()
			->addAttributeToFilter('order_id', array('eq'=>$order->getId()));
			$orders->getSelect()->limit(1);
			
			if ((int)$orders->count() !== 0) {
				return $this;
			}
			
			if ($order->getState() == Mage_Sales_Model_Order::STATE_NEW || $order->getState() == Mage_Sales_Model_Order::STATE_PROCESSING) {
				try {
					if(!$order->canInvoice()) {
						$order->addStatusHistoryComment('Order cannot be invoiced.', false);
						$order->save();
					}
			
					//START Handle Invoice
					$invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();
			
					$invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_OFFLINE);
					$invoice->register();
			
					$invoice->getOrder()->setCustomerNoteNotify(false);
					$invoice->getOrder()->setIsInProcess(true);
					$order->addStatusHistoryComment('Automatically INVOICED by Automation tool.', false);
			
					$transactionSave = Mage::getModel('core/resource_transaction')
					->addObject($invoice)
					->addObject($invoice->getOrder());
			
					$transactionSave->save();
					//END Handle Invoice
			
					//START Handle Shipment
					$shipment = $order->prepareShipment();
					$shipment->register();
			
					$order->setIsInProcess(true);
					$order->addStatusHistoryComment('Automatically SHIPPED by Automation tool.', false);
			
					$transactionSave = Mage::getModel('core/resource_transaction')
					->addObject($shipment)
					->addObject($shipment->getOrder())
					->save();
					//END Handle Shipment
				} catch (Exception $e) {
					$order->addStatusHistoryComment('Exception occurred during automaticallyInvoiceShipCompleteOrder action. Exception message: '.$e->getMessage(), false);
					$order->save();
				}
