Change Order status to processing automatically

Question

I'm using a custom payment module Billdesk and I want the order status to be processing automatically when payment is completed using this module. In all other cases order status should be pending which is available in Magento by default.

While using Billdesk module if there is a due amount in that case also, I want order status to be pending by default. Here is my observer function for checkout_onepage_controller_success_action event

 <?php
class Embitel_Billdesk_Model_Observer {
    public function updateStatus($observer){        
        $order_id=Mage::getSingleton('checkout/session')->getLastOrderId(); 
        $order = Mage::getModel('sales/order')->load($order_id);           

        if($order_id){
        $order = Mage::getModel('sales/order')->load($order_id);
        $payment_method_code = $order->getPayment()->getMethodInstance()->getCode();

            if('embitel_billdesk' == $payment_method_code ){
            $order->setState(Mage_Sales_Model_Order::STATE_PROCESSING, true)->save();
            }
        }
    }
}

I'm not sure, how I can add the validation that order status will be set to processing when card type is credit and there is no due amount. Is there a way to check the due amount on frontend? If I'm using credit cart, will the order amount be the due amount?

Answer 1

I can give you an example how to add additional status to existed payment method.

Magento by default in system / configuration has such as 'New Order Status'.

Let's look at SavedCC:

Now we change system.xml file.

Original:

                    <order_status translate="label">
                        <label>New Order Status</label>
                        <frontend_type>select</frontend_type>
                        <source_model>adminhtml/system_config_source_order_status_new</source_model>
                        <sort_order>2</sort_order>
                        <show_in_default>1</show_in_default>
                        <show_in_website>1</show_in_website>
                        <show_in_store>0</show_in_store>
                    </order_status>

You need to replace

<source_model>adminhtml/system_config_source_order_status_new</source_model>

with:

<source_model>adminhtml/system_config_source_order_status_newprocessing</source_model>

And you will get:

Answer 2

As per as your question,order status become processing whenever " card type is credit and there is no due amount" this two condition is total depends on what payment gatway return after payment done or failed and you extension code.

First you need to check what params will coming when customer is return from paymemt gateway.Depend on this params,you can dietect payment is done not etc.

Also, i have optimized code:

<?php
class Embitel_Billdesk_Model_Observer {
    public function updateStatus($observer){

        $orderIds = $observer->getEvent()->getOrderIds();
        if (empty($orderIds) || !is_array($orderIds)) {
            return;
        }

        $orderIds = $observer->getEvent()->getOrderIds();

        foreach($orderIds as $eachOrderId){
        $order = Mage::getModel('sales/order')->load($eachOrderId);           
            if($order->getId()){
            $order = Mage::getModel('sales/order')->load($order_id);
                if($order->getPayment()->getMethodInstance()->getCode()=='embitel_billdesk'  ){

                    $state  = Mage_Sales_Model_Order::STATE_PROCESSING;
                    $status = true;
                    $order->setState($state, $status);
                    $order->save();

                }
            }
        }
    }

}
