I need to add admin username in order comment history whenever I create

• invoice


• shipment


• and On Cancel order.

I recently did this work through observers

You have to add these event in your module event file VendorYourmodulenameetcevents.xml

For Invoice

<event name="sales_order_invoice_register">
 <observer name="vendor_yourmodulename_observer_addcommentonaction" instance="VendorYourmodulenameObserverAddcommentonaction" />
</event>

For Cancel

<event name="order_cancel_after">
 <observer name="vendor_yourmodulename_observer_addcommentoncancelaction" instance="VendorYourmodulenameObserverAddcommentoncancelaction" />
</event>

For Shipment

<event name="sales_order_shipment_save_after">
 <observer name="vendor_yourmodulename_observer_addcommentonshipmentaction" instance="VendorYourmodulenameObserverAddcommentonshipmentaction" />
</event>

Observer files

For Invoice Add file in your module VendorYourmodulenameObserverAddcommentonaction.php

<?php
namespace VendorYourmodulenameObserver;

class Addcommentonaction implements MagentoFrameworkEventObserverInterface

 public function execute(MagentoFrameworkEventObserver $observer)
 

 $order= $observer->getData('order');
 //$order->doSomething();
 $authsession = MagentoFrameworkAppObjectManager::getInstance()->create(MagentoBackendModelAuthSession::class);
 $username = $authsession->getUser()->getUsername();


 $notify = false;
 $visible = false;
 $history = $order->addStatusHistoryComment("Invoice generated"." (".$username.")", $order->getStatus());
 $history->setIsVisibleOnFront($visible);
 $history->setIsCustomerNotified($notify);
 $history->save();

 return $this;
 

For Cancel Add file in your module VendorYourmodulenameObserverAddcommentoncancelaction.php

 <?php
namespace VendorYourmodulenameObserver;

class Addcommentoncancelaction implements MagentoFrameworkEventObserverInterface

 public function execute(MagentoFrameworkEventObserver $observer)
 

 $order= $observer->getData('order');
 //$order->doSomething();
 $authsession = MagentoFrameworkAppObjectManager::getInstance()->create(MagentoBackendModelAuthSession::class);
 $username = $authsession->getUser()->getUsername();


 $notify = false;
 $visible = false;
 $history = $order->addStatusHistoryComment("Order canceled"." (".$username.")", $order->getStatus());
 $history->setIsVisibleOnFront($visible);
 $history->setIsCustomerNotified($notify);
 $history->save();

 return $this;
 

For Shipment Add file in your module VendorYourmodulenameObserverAddcommentonshipmentaction.php

 <?php
namespace VendorYourmodulenameObserver;

class Addcommentonshipmentaction implements MagentoFrameworkEventObserverInterface

 public function execute(MagentoFrameworkEventObserver $observer)
 

 $shipment = $observer->getEvent()->getShipment();
 $order = $shipment->getOrder();
 $authsession = MagentoFrameworkAppObjectManager::getInstance()->create(MagentoBackendModelAuthSession::class);
 $username = $authsession->getUser()->getUsername();


 $notify = false;
 $visible = false;
 $history = $order->addStatusHistoryComment("Shipment generated"." (".$username.")", $order->getStatus());
 $history->setIsVisibleOnFront($visible);
 $history->setIsCustomerNotified($notify);
 $history->save();

 return $this;
