Magento Order History Comments: Modify Date - magento

Question

I am creating a script to add orders programmatically in Magento. I need help to change the date of the entries in the Comments History (quote, invoice, shipping, etc.). I can manipulate the date of the order itself (setCreatedAt) and some of the comments related to the creation of the order are correct (e.g. "Sep 29, 2008 8:59:25 AM|Pending Customer Notification Not Applicable"), but I cannot change the date of the comment when I use addStatusHistoryComment...
Here's a snippet of my code:
try {
if(!$order->canInvoice()) {
Mage::throwException(Mage::helper('core')->__('Cannot create an invoice.'));
}
$invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();
if (!$invoice->getTotalQty()) {
Mage::throwException(Mage::helper('core')->__('Cannot create an invoice without products.'));
}
$invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_OFFLINE);
$invoice->setCreatedAt('2008-09-23 13:05:20');
$invoice->register();
$invoice->getOrder()->setCustomerNoteNotify(true);
$invoice->getOrder()->setIsInProcess(true);
$transactionSave = Mage::getModel('core/resource_transaction')
->addObject($invoice)
- >addObject($invoice->getOrder());
$transactionSave->save();
//END Handle Invoice
//START Handle Shipment
$shipment = $order->prepareShipment();
$shipment->setCreatedAt('2008-09-23 14:20:10');
$shipment->register();
$order->setIsInProcess(true);
$order->addStatusHistoryComment('Shipping message goes here...', true);
$shipment->setEmailSent(true);
$transactionSave = Mage::getModel('core/resource_transaction')
->addObject($shipment)
->addObject($shipment->getOrder())
->save();
$track = Mage::getModel('sales/order_shipment_track')
->setShipment($shipment)
->setData('title', 'Some tracking no.')
->setData('number', '111222333444')
->setData('carrier_code', 'fedex') //custom, fedex, ups, usps, dhl
->setData('order_id', $shipment->getData('order_id'))
->save();
//END Handle Shipment
}
catch (Mage_Core_Exception $ex) {
echo "Problem creating order invoice and/or shipment: ".$ex."\n";
}
Thanks in advance.

Answer 1

If I understand your question correctly, you just need to do this:
$comments = $order->getStatusHistoryCollection(true);
$comments now contains a collection of all the status history comments, and you can loop over them with whatever sort of criteria you like.
foreach ($comments as $c) {
if ( /* some stuff */ ) {
$c->setData('created_at',$new_date)->save();
}
}

Answer 2

So this is untested, but should work:
You need to create a new method based off addStatusHistoryComment:
/app/code/core/Mage/Sales/Model/Order.php
/*
* Add a comment to order
* Different or default status may be specified
*
* #param string $comment
* #param string $status
* #return Mage_Sales_Model_Order_Status_History
*/
public function addStatusHistoryComment($comment, $status = false)
{
if (false === $status) {
$status = $this->getStatus();
} elseif (true === $status) {
$status = $this->getConfig()->getStateDefaultStatus($this->getState());
} else {
$this->setStatus($status);
}
$history = Mage::getModel('sales/order_status_history')
->setStatus($status)
->setComment($comment)
->setEntityName($this->_historyEntityName);
->setCreatedAt('2008-09-23 14:20:10'); //I added this line
$this->addStatusHistory($history);
return $history;
}
Obviously you either need to rewrite this method, or refactor the code to do the same.
