debug email sent in checkout

Question

I want to stop magento sending new order email in some cases.

I want to know from the community how to debug and backtrace the function that really send the order email confirmation email.

I've this event :

<sales_order_place_after>
                <observers>
                    <xx_yy_Model_sales_observer>
                        <type>singleton</type>
                        <class>xx_yy_Model_Sales_Observer</class>
                        <method>save_order</method>
                    </xx_yy_Model_sales_observer>
                </observers>
            </sales_order_place_after>

And in my save_order function i do this :

try{
            $order->setEmailSent(1);
            $order->setStatus("holded");
            $order->save();
        }
        catch(exception $e){
            Mage::log('Non inoltra ordine', 1,'orders.log');
            Mage::log($e->getMessage(),1,'orders.log');
        }

But i still receive the new email order. I'm trying to debug core_email_template_mailer and core_email_template but seems that the email is not sent from there.

any help could be appreciated!!

Answer 1

I think you can try to create one more Observer method for event sales_order_place_before and move

$order->setEmailSent(1);

to that new Observer method

Answer 2

Magento does not use events to send emails for order confirmation.

The email is sent on order save, specifically in the method sendNewOrderEmail() which is defined in /app/code/core/Mage/Sales/Model/Order.php (assuming that there is not custom module that modify it).

There is a setting in the backend: system -> config > sales emails where you can disable them.

If you want another condition I would write a custom module to extend Mage_Sales_Model_Order and add my custom check there in an overwrite of sendNewOrderEmail().
