Magento Invoice sendEmail() with PDF attachment - magento

Question

I use the following code to load an invoice and send email programatically:
<?php
$invoice = Mage::getModel('sales/order_invoice')
->loadByIncrementId($invoice_queue['increment_id']);
if (null !== $invoice->getId()){
$invoice->sendEmail();
echo "- Done Invoice #". $invoice_queue['increment_id'] ."\r\n";
}
$invoice = null;
?>
This appears to be sending the invoice email correctly. However, the PDF attachment of the invoice isn't there in the email.
If I were to send the email via magento, it works.
Any idea how to get the PDF to be attached, when calling sendEmail() function?

Answer 1

For sending invoice email you need to overwrite
In mage/core/model/email/template.php add this method at the end of the file:
public function addAttachment(Zend_Pdf $pdf){
$file = $pdf->render();
$attachment = $this->getMail()->createAttachment($file);
$attachment->type = 'application/pdf';
$attachment->filename = 'test.pdf';
}
2 In sales/model/order/Invoice.php add the code between comments(2 lines of code) to the function sendEmail like this:
<?php
public function sendEmail($notifyCustomer=true, $comment='')
{
if (!Mage::helper('sales')->canSendNewInvoiceEmail($this->getOrder()->getStore()->getId())) {
return $this;
}
$currentDesign = Mage::getDesign()->setAllGetOld(array(
'package' => Mage::getStoreConfig('design/package/name', $this->getStoreId()),
'store' => $this->getStoreId()
));
$translate = Mage::getSingleton('core/translate');
/* #var $translate Mage_Core_Model_Translate */
$translate->setTranslateInline(false);
$order = $this->getOrder();
$copyTo = $this->_getEmails(self::XML_PATH_EMAIL_COPY_TO);
$copyMethod = Mage::getStoreConfig(self::XML_PATH_EMAIL_COPY_METHOD, $this->getStoreId());
if (!$notifyCustomer && !$copyTo) {
return $this;
}
$paymentBlock = Mage::helper('payment')->getInfoBlock($order->getPayment())
->setIsSecureMode(true);
$mailTemplate = Mage::getModel('core/email_template');
if ($order->getCustomerIsGuest()) {
$template = Mage::getStoreConfig(self::XML_PATH_EMAIL_GUEST_TEMPLATE, $order->getStoreId());
$customerName = $order->getBillingAddress()->getName();
} else {
$template = Mage::getStoreConfig(self::XML_PATH_EMAIL_TEMPLATE, $order->getStoreId());
$customerName = $order->getCustomerName();
}
// attachment here
$pdf = Mage::getModel('sales/order_pdf_invoice')->getPdf(array($this));
$mailTemplate->addAttachment($pdf);
if ($notifyCustomer) {
$sendTo[] = array(
'name' => $customerName,
'email' => $order->getCustomerEmail()
);
if ($copyTo && $copyMethod == 'bcc') {
foreach ($copyTo as $email) {
$mailTemplate->addBcc($email);
}
}
// enter code here
}
if ($copyTo && ($copyMethod == 'copy' || !$notifyCustomer)) {
foreach ($copyTo as $email) {
$sendTo[] = array(
'name' => null,
'email' => $email
);
}
}
foreach ($sendTo as $recipient) {
$mailTemplate->setDesignConfig(array('area'=>'frontend', 'store'=>$order->getStoreId()))
->sendTransactional(
$template,
Mage::getStoreConfig(self::XML_PATH_EMAIL_IDENTITY, $order->getStoreId()),
$recipient['email'],
$recipient['name'],
array(
'order' => $order,
'invoice' => $this,
'comment' => $comment,
'billing' => $order->getBillingAddress(),
'payment_html'=> $paymentBlock->toHtml(),
)
);
}
$translate->setTranslateInline(true);
Mage::getDesign()->setAllGetOld($currentDesign);
return $this;
} ?>
Now when you create an invoice from the back office and you select to notify customer a pdf attachment should be sent as well.
