Magento – SMS for different order events in Magento

magento-1.9orders

I want to send SMS to customers when ever an order status changes from pending > processing > complete (for all sort of changes).

For pending process(when place order is clicked), i should able to get a SMS. Below is the code: Onserver.php

public function sendSMS ($observer)
    {
        $orderIds = $observer->getEvent()->getOrderIds();
        foreach($orderIds as $orderId)
        {
            $order = Mage::getModel('sales/order')->load($orderId);
            $orderId = $order->getId();
            $order_status = $order->getStatus();
            $smsMessageTemp =Mage::getModel('core/variable')->loadByCode('template_sms_order_placement_confirmation')->getValue('plain');
                . . . . .
         }
 }

When admin changes the state from pending to processing , how to send sms for different events.

In my .xml file:

     <events> 
        <sales_order_save_after>
            <observers>
                <Metro_SellerPurchaseOrder>
                    <type>singleton</type>
                    <class>sellerpurchaseorder/observer</class>
                   <method>sendSMS</method>
                </Metro_SellerPurchaseOrder>
           </observers>
        </sales_order_save_after>
    </events>

Please suggest.

First you need to track order status changes,

Magento is provide to track old data and new changed data using getOrigData() and getData() on save event fire.So easily using the feature,you can get changes Status and on basic of this,you can fire the Sms

Error:

When sales_order_save_after event is fire then you can get only one order data that means code at observer is wrong.

Solution:

As i said that when Model is saving then you can get old and new Data using

Current Data: $Object->getOrigData();

and

Changing new Data : $object->getData()

Using those function when you can easy track order status changes.

And suggesting to you that use event sales_order_save_commit_after instead of sales_order_save_after because if any issue has occurred during the save magento is roll back to old data and show the errors.

you can Old status by $OldStatus=$order->getOrigData('status')

and new Status

$NewStatus=$order->getData('status');

Code:

  public  function sendSMS($observer)
    {
        $order = $observer->getEvent()->getOrder();

        if (!$order->getId()) {
            //order not saved in the database
            return $this;
        }

        /* @var $order Mage_Sales_Model_Order */

        $OldData=$order->getOrigData();
        $NewData=$order->getData();
        $OldState==$order->getOrigData('state');
        $NewState=$order->getState();
        $OldStatus=$order->getOrigData('status');
        $NewStatus=$order->getStatus();


        /* Fire sms when New Status  and  old Statu are not same */
        if($OldStatus!=$NewStatus){
            //fire sms;
            $smsMessageTemp =Mage::getModel('core/variable')->loadByCode('template_sms_order_placement_confirmation')->getValue('plain');
        }



        return $this;
    }

Solution - Overriding the `Meta` class

I was able to achieve my goal by simply overriding the class Magento\SalesSequence\Model\ResourceModel\Meta. While this class is usually solicited for grabing the current sequence profile from the database, with a simple override we can adapt it so it passes the Prefix and Suffix to the Magento\SalesSequence\Model\Sequence class which will use them to generate the final number. This class also gives us access to some useful parameters as the entity_type and store_id via the $object variable.

Working Example

NameSpace/Module/etc/di.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
    <preference for="Magento\SalesSequence\Model\ResourceModel\Meta" type="NameSpace\Module\Override\SalesSequence\ResourceModel\Meta" />
</config>

NameSpace/Module/Override/SalesSequence/ResourceModel/Meta.php

<?php
namespace NameSpace\Module\Override\SalesSequence\ResourceModel;

class Meta extends \Magento\SalesSequence\Model\ResourceModel\Meta
{

    protected function _afterLoad(\Magento\Framework\Model\AbstractModel $object)
    {

        $entityType = $object->getEntityType(); //order/invoice/creditmemo/shipment
        $storeId = $object->getStoreId(); //CURRENT STORE ID

        $activeProfile = $this->resourceProfile->loadActiveProfile($object->getId());
        $activeProfile->setPrefix('ORD-'); //SET CUSTOM PREFIX - DEFAULT: store_id
        $activeProfile->setSuffix('A'); //SET CUSTOM SUFFIX
        $activeProfile->setStartValue('1'); //SET START VALUE - DEFAULT: 1
        $activeProfile->setStep('1'); //SET INCREMENT STEP - DEFAULT: 1

        //[UPDATE] USEFUL FOR SHARED ORDER NUMBERS WITHIN MULTIPLE STORES
        $object->setSequenceTable('custom_table'); //SET CUSTOM INCREMENT TABLE - DEFAULT: sequence_{entity_type}_{store_id}


        //SET DATA TO active_profile
        $object->setData(
            'active_profile',
            $activeProfile
        );

        return $this;
    }

}
?>

This above solution gives some flexibility but does not allow to edit the number padding or to reset the sequence after a certain period.

Edit Pattern & Padding

To edit the Pattern, one might simply override the DEFAULT_PATTERN constant inside the Magento\SalesSequence\Model\Sequence class.

Reseting Sequence after X Period

This should be possible by simply resetting the AUTO_INCREMENT for the specific sequence_{entity_type}_{store_id} table following certain conditions from inside our Meta class. This way, as our number will be generated by the Sequence class, the next value will start over from the start_value.
