Access Comments from Credit Memo After sales_order_creditmemo_refund Event

creditmemomagento-1.7orders

I am generating XML which is sent to an external system whenever a Credit Memo is generated. I am using the event sales_order_creditmemo_refund which gives me the credit memo and order models (which I am using to generate the appropriate XML)

$creditMemo = $observer->getEvent()->getCreditmemo();
$order      = $creditMemo->getOrder();

However I am having trouble accessing comments. I can see in Mage_Sales_Model_Order_Creditmemo there is getCommentsCollection() but this is not returning anything.

I am guessing the comments are added to the model at a later stage, should I be using a different event for my observer?

I can see that Mage::dispatchEvent('sales_order_creditmemo_refund', array($this->_eventObject=>$this)); is located inside the refund() method of the same model, but the only other event I can see in the model is sales_order_creditmemo_cancel

Ok so after posting the question I immediately find the answer!

For anyone else with this issue:

Checking the saveAction() within Mage_Adminhtml_Sales_Order_CreditmemoController reveals that the comments are initially only added to the session:

$data = $this->getRequest()->getPost('creditmemo');
if (!empty($data['comment_text'])) {
   Mage::getSingleton('adminhtml/session')->setCommentText($data['comment_text']);
}

So from within the observer I can simply call Mage::getSingleton('adminhtml/session')->getCommentText() to return the comment.

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.

Magento – Magento and Authorize Suspected Fraud Credit Memo

In your above scenario there is some more question arise.

Your authorize.net set in which mode? authorize or authorize and capture?
When authorize.net returns suspected fraud code at that time it actually capture the payment from customer or not? if not capture payment it should not generate invoice.
When authorize.net approve transaction and you run get payment update your order state change to processing but at that time do you get any transaction_id in your response or not. if you get and your invoice already generated might you need to update your invoice and fill the transaction_id pragmatically if you want to create credit memo online by using same authorize.net.

The easiest solution is to refund off-line if this happen rarely. to refund payment off-line and on-line also there is different way check below link for details Credit memo vs Refund Which one is true? Magento 1.9
