Automatically changing order status to complete for admin orders

Question

I need a way to set the order status automatically to completed when the order is created in admin and payment method is one of the two possibilities for admin orders. In this case it is unnecessary step to create invoice and shipment.

Already tried this, but could not get it to work:

Answer 1

follow this tutorial

We need to add following code in config.xml

<sales_order_place_after>
    <observers>
        <b4u_order_observer>
            <type>singleton</type>
            <class>Mshop_B4u_Model_Observer</class>
            <method>after_order_placed</method>
        </b4u_order_observer>
    </observers>
</sales_order_place_after>

Need to write the following code in observer( mshop -> b4u -> model -> Observer.php )

public static function after_order_placed($observer)
{
    $event = $observer->getEvent();
    $order = $event->getOrder();
    $order_no   = (string) $order->getRealOrderId();

    $order->loadByIncrementId($order_no);
    $order->setState(Mage_Sales_Model_Order::STATE_COMPLETE, true);
    $order->save();
    return true;
}

And we can create invoice also through this script. for that we need to add extra code and the above function should look like below,

public static function after_order_placed($observer)
{
    $event = $observer->getEvent();
    $order = $event->getOrder();
    $order_no   = (string) $order->getRealOrderId();

    // **** This is for creating invoice *****
    $order = Mage::getModel('sales/order')->loadByIncrementId($order_no);
    try {
        if(!$order->canInvoice()) {
            Mage::throwException(Mage::helper('core')->__('Cannot create an invoice.'));
        }

        $invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();

        if (!$invoice->getTotalQty()) {
            Mage::throwException(Mage::helper('core')->__('Cannot create an invoice without products.'));
        }

        $invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_ONLINE);
        //Or you can use
        //$invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_OFFLINE);

        $invoice->register();
        $transactionSave = Mage::getModel('core/resource_transaction')
            ->addObject($invoice)
            ->addObject($invoice->getOrder());

        $transactionSave->save();
    } catch (Mage_Core_Exception $e) {
    }

    // **** This is for set as order complete *****
    $order->loadByIncrementId($order_no);
    $order->setState(Mage_Sales_Model_Order::STATE_COMPLETE, true);
    $order->save();
    return true;
}
