send new order email with cron job only

Question

I want to disable the default new order email sending functionality and instead I want to send this email with cron job only. How can I identify, if the new order is placed and send email ?

Answer 1

Here is a simple way of doing it.
Rewrite the method Mage_Sales_Model_Order::sendNewOrderEmail and make it look like this:

public function sendNewOrderEmail() {
    if (!$this->getForceSendEmail()) {
        return $this;
    }
    //do what it does by default
    parent::sendNewOrderEmail();
}

This will prevent the e-mail sending from the website because getForceSendEmail will always return false (unless you tell it not to).

Now, when running the cron to send e-mails you will have to do somthing like this:

$orders = ....; //retrieve orders somehow
$foreach ($orders as $order) {
    $order->setForceSendEmail(true); //tell the order to force the e-mail
    $order->sendNewOrderEmail();
}

Answer 2

Magento is send new order mail from Mage_Sales_Model_Sales class function sendNewOrderEmail

In overrive this function using Override class make this function

 public function sendNewOrderEmail(){
return;
}

Create another function which code is replicated function CustomsendNewOrderEmail from sendNewOrderEmail() Assume

Code

setCouponCode('bal'); //$this->_getResource()->saveAttribute($this, 'coupon_code');

    return;
}
public function CustomsendNewOrderEmail(){
    parent::sendNewOrderEmail();
}

}

Then Using cron job hit this function:

$Order=Mage::getModel('sales/order')->load($orderId);
$Order->CustomsendNewOrderEmail();

Create a module:

config.xml code ((app/code/local/Bh/ZeroSubtotalpaymentmethod/etc/))

<?xml version="1.0" ?>
<config>
    <modules>
        <Bh_ZeroSubtotalpaymentmethod>
            <version>1.0.1</version>
        </Bh_ZeroSubtotalpaymentmethod>
    </modules>
    <global>
        <models>
            <zerosubtotalpaymentmethod>
            <class>Bh_ZeroSubtotalpaymentmethod_Model</class>
            </zerosubtotalpaymentmethod>
            <sales>
                <rewrite>
                    <order>Bh_ZeroSubtotalpaymentmethod_Model_Order</order>
                </rewrite>
            </sales>
        </models>
    </global>
    <crontab>
    <jobs>
        <autosend_order>
            <schedule><cron_expr>20 * * * *</cron_expr></schedule>
            <run><model>zerosubtotalpaymentmethod/observer::myordersend</model></run>
        </autosend_order>
    </jobs>
    </crontab>
</config>

**Order.php ,which rewrite Order.php**(app/code/local/Bh/ZeroSubtotalpaymentmethod/Model/)

<?php
class Bh_ZeroSubtotalpaymentmethod_Model_Order extends Mage_Sales_Model_Order{
    public function sendNewOrderEmail(){
        // $this->setCouponCode('bal');
        //$this->_getResource()->saveAttribute($this, 'coupon_code');

        return;
    }
    public function CustomsendNewOrderEmail(){
        parent::sendNewOrderEmail();
    }
}

Cron file Observer.php(app/code/local/Bh/ZeroSubtotalpaymentmethod/Model/)

<?php
class Bh_ZeroSubtotalpaymentmethod_Model_Observer
{
    public function myordersend(){

    $Order_collection = Mage::getModel("sales/order")->getCollection()->addFieldToFilter('email_sent',array('neq'=>array(1)));
            foreach($Order_collection as $Order)
            {
                try {

                $Myorder=Mage::getModel('sales/order')->load($Order->getId());
                $Myorder->CustomsendNewOrderEmail();
                }catch(Exception $e){
                }
            }
    }
}

also create module

app/etc/modules/Bh_ZeroSubtotalpaymentmethod.xml

Code:

<?xml version="1.0" ?>
<config>
<modules>
    <Bh_ZeroSubtotalpaymentmethod>
        <active>true</active>
        <codePool>local</codePool>
    </Bh_ZeroSubtotalpaymentmethod>
</modules>
</config>
