Magento – Event before save order or place order in magento 1.9.1.1

ce-1.9.1.1checkoutevent-observermagento-1.9sales-order

Get event before place order or save new order. I have tried the sales_order_save_before event but I didn't get any data. Below is my code,
In config.xml:

<sales_order_save_before>
    <observers>
        <custom_observerwww>
            <type>singleton</type>
            <class>Custom_Module_Model_Observer</class>
            <method>removeItems</method>
        </custom_observerwww>
    </observers>
</sales_order_save_before>

In Observer.php:

class Custom_Module_Model_Observer {
    public function removeItems($observer){
        Mage::log($observer->getEvent()->getOrder(),null,"order.log",true);
    }

There is no data received in log file.

Try this da. It worked for me.

config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Always_Nallavan>
            <version>0.0.1</version>
        </Always_Nallavan>
    </modules>
    <global>
        <models>
            <alwaysnallavan>
                <class>Nallavan_Model</class>
            </alwaysnallavan>
        </models>
        <events>
            <sales_order_place_before>
                <observers>
                    <always_nallavan_model_observer>
                        <type>singleton</type>
                        <class>Always_Nallavan_Model_Observer</class>
                        <method>dandanaka</method>
                    </always_nallavan_model_observer>
                </observers>
            </sales_order_place_before>
        </events>
    </global>
</config>

Observer.php

<?php

class Always_Nallavan_Model_Observer
{

    public function dandanaka($observer)
    {
        $data = $observer->getEvent()->getOrder();
        Mage::log($data->debug(), null, "order.log", true);
    }
}

Note the debug() method, that returns a string representation of any Varien_Object instance.

Magento – Save admin name to order_status change using an Observer

EDIT:

You can also do the following, which I would recommend over the previous solution I posted. Mostly because it doesn't use setPost, which I would consider scary.

config.xml:

<adminhtml>
  <events>
    <sales_order_status_history_save_before>
      <observers>
        <module_status_history_save_before>
          <class>module/observer</class>
          <method>commentSaveBefore</method>
        </module_status_history_save_before>
      </observers>
    </sales_order_status_history_save_before>
  </events>
</adminhtml>

Observer.php:

public function commentSaveBefore($obs) {
    $event = $obs->getEvent();
    $status = $event->getDataObject();
    $status->setComment($status->getComment().$this->_getAppend());
}

protected function _getAppend()
{
    $admin = Mage::getSingleton('admin/session')->getUser();
    $username = $admin->getUsername();
    return " : " . $username;
}

This would accomplish the same thing, except you're intercepting the model before it gets saved, allowing you to alter the comment without having to use setPost().

Original Post: You could do the following:

config.xml:

<adminhtml>
    <events>
        <controller_action_predispatch_adminhtml_sales_order_addComment>
            <observers>
                <module_order_save_comment>
                    <class>module/observer</class>
                    <method>adminhtmlSavingOrderComment</method>
                </module_order_save_comment>
            </observers>
        </controller_action_predispatch_adminhtml_sales_order_addComment>
    </events>
</adminhtml>

Observer.php:

public function adminhtmlSavingOrderComment($obs) {
    $event = $obs->getEvent();
    $order = $event->getOrder();
    $data = Mage::app()->getRequest()->getPost('history');
    if ($data && isset($data['comment'])) {
        $data['comment'] .= $this->_getAppend();
        Mage::app()->getRequest()->setPost('history', $data);
    }
}

protected function _getAppend()
{
    $admin = Mage::getSingleton('admin/session')->getUser();
    $username = $admin->getUsername();
    return " : " . $username;
}

This should work for you.
