Magento 2: Call to a member function setState() on array

Question

I want to change the order Status programmatically but when I run the function realTest() as I mentioned below then it gives me an error Call to a member function setState() on array in the below function it mentions line number 5. I also tried function use Magento\Sales\Model\Order; in place of other class as I mentioned in my code but in both scenarios, it gives me the same error also when I tried the array to print_r($orderState) then it returns me null array.

use \Magento\Sales\Api\OrderRepositoryInterface;
public function realTest(){
        try{
            $orderId = 000256076;
            // obtain the order with the order ID
            $order = $this->_orderRepository->get($orderId);
            $orderState = \Magento\Sales\Model\Order::STATE_PROCESSING;
            $order->setState($orderState)->setStatus(\Magento\Sales\Model\Order::STATE_PROCESSING);
            $this->_orderRepository->save($order);
            return true;
        } catch (\Exception $e){
            echo 'Message: ' .$e->getMessage();
            // add some logging here
            return false;
        }

    }

Answer 1

Give a try to below code.

With Increment Id

$incrementId = 000256076;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('\Magento\Sales\Model\Order')->loadByIncrementId($incrementId);
$orderState = \Magento\Sales\Model\Order::STATE_PROCESSING;
$order->setState($orderState)->setStatus(\Magento\Sales\Model\Order::STATE_PROCESSING);
$order->save();

With Order Id

$orderId = 1271; //check if the order exists with this id or not
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('\Magento\Sales\Model\Order')->load($orderId);
$orderState = \Magento\Sales\Model\Order::STATE_PROCESSING;
$order->setState($orderState)->setStatus(\Magento\Sales\Model\Order::STATE_PROCESSING);
$order->save();

Answer 2

Try This :-

/**Magento/Sales/Model/Order $salesOrder**/
$orderId = 12345;
$statusCode = \Magento\Sales\Model\Order::STATE_PROCESSING;

$order = $this->salesOrder->load($orderId);
$order->setState($order->getState())->setStatus($statusCode);
$order->save();

Try to implement this check

use \Magento\Sales\Api\OrderRepositoryInterface;
    public function realTest(){
            try{
                $orderId = 256076;
                // obtain the order with the order ID
                $order = $this->_orderRepository->get($orderId);
                if(!empty($order->getData()){
                   $orderState = \Magento\Sales\Model\Order::STATE_PROCESSING;
                   $order->setState($orderState)->setStatus(\Magento\Sales\Model\Order::STATE_PROCESSING);
                   $this->_orderRepository->save($order);
                   return true;
                }
            } catch (\Exception $e){
                echo 'Message: ' .$e->getMessage();
                // add some logging here
                return false;
            }

        }

Your code seems to good but Once try to use following code

use \Magento\Sales\Api\OrderRepositoryInterface;
public function realTest(){
        try{
            $orderId = 1271;
            // obtain the order with the order ID
            $order = $this->_orderRepository->get($orderId);
            $orderState = \Magento\Sales\Model\Order::STATE_PROCESSING;
            $order->setState($orderState)->setStatus(\Magento\Sales\Model\Order::STATE_PROCESSING);
            $this->_orderRepository->save($order);
            return true;
        } catch (\Exception $e){
            echo 'Message: ' .$e->getMessage();
            // add some logging here
            return false;
        }

    }
