Magento 2 Attach PDF to Invoice Email
Table of Contents
Magento 2 uses the TransportBuilder class to send emails, but it doesn’t support file attachments.
So to add email attachments programmatically, first of all, you need to create the new TransportBuilder class in app/code/Vendor/Module /Mail/Template/ TransportBuilder.php
<?php
namespace Vendor\Module\Mail\Template;
class TransportBuilder extends \Magento\Framework\Mail\Template\TransportBuilder
{
/**
* addAttachment
*
* @param mixed $body
* @param string $filename
* @param mixed $mimeType
* @param mixed $disposition
* @param mixed $encoding
* @return object
*/
public function addAttachment(
$body,
$filename = null,
$mimeType = \Zend_Mime::TYPE_OCTETSTREAM,
$disposition = \Zend_Mime::DISPOSITION_ATTACHMENT,
$encoding = \Zend_Mime::ENCODING_BASE64
) {
$attachmentPart = new \Zend\Mime\Part();
$attachmentPart->setContent($body)
->setType($mimeType)
->setFileName($filename)
->setEncoding($encoding)
->setDisposition($disposition);
return $attachmentPart;
}
}Then create the SenderBuilder class to add attachment files. With this class, you can add PDF, image, or calendar files with email.
Add the SenderBuilder file in app/code/Vendor/Module/Model/Sales/Order/Email/SenderBuilder.php
<?php
namespace Vendor\Module\Model\Sales\Order\Email;
use Magento\Framework\Mail\Template\TransportBuilder;
use Magento\Framework\Mail\Template\TransportBuilderByStore;
use Magento\Sales\Model\Order\Email\Container\IdentityInterface;
use Magento\Sales\Model\Order\Email\Container\Template;
/**
* Email sender builder for attachments
*/
class SenderBuilder extends \Magento\Sales\Model\Order\Email\SenderBuilder
{
/**
* @param Template $templateContainer
* @param IdentityInterface $identityContainer
* @param TransportBuilder $transportBuilder
* @param TransportBuilderByStore $transportBuilderByStore
* @param \Magento\Framework\Filesystem\Driver\File $reader
*/
public function __construct(
Template $templateContainer,
IdentityInterface $identityContainer,
TransportBuilder $transportBuilder,
TransportBuilderByStore $transportBuilderByStore = null,
\Vendor\Module\Helper\Data $helper,
\Magento\Framework\Filesystem\Driver\File $reader
) {
parent::__construct(
$templateContainer,
$identityContainer,
$transportBuilder
);
$this->helper = $helper;
$this->reader = $reader;
}
/**
* Prepare and send email message
*
* @return void
*/
public function send()
{
$this->configureEmailTemplate();
$this->transportBuilder->addTo(
$this->identityContainer->getCustomerEmail(),
$this->identityContainer->getCustomerName()
);
$copyTo = $this->identityContainer->getEmailCopyTo();
if (!empty($copyTo) && $this->identityContainer->getCopyMethod() == 'bcc') {
foreach ($copyTo as $email) {
$this->transportBuilder->addBcc($email);
}
}
/* to attach events in invoice email */
$templateVars = $this->templateContainer->getTemplateVars();
$transport = $this->transportBuilder->getTransport();
if (!empty($templateVars['order'])) {
$order = $templateVars['order'];
foreach ($order->getAllItems() as $item) {
$data = $this->helper->createPdfFile($item, $order->getId());
if (!empty($data) && !empty($data['filename']) && !empty($data['pdfFile'])) {
// adds attachment in mail
$attachmentPart = $this->transportBuilder->addAttachment(
$this->reader->fileGetContents($data['pdfFile']),
$data['filename'],
'application/pdf'
);
$message = $transport->getMessage();
$body = \Zend\Mail\Message::fromString($message->getRawMessage())->getBody();
$body = \Zend_Mime_Decode::decodeQuotedPrintable($body);
$html = '';
if ($body instanceof \Zend\Mime\Message) {
$html = $body->generateMessage(\Zend\Mail\Headers::EOL);
} elseif ($body instanceof \Magento\Framework\Mail\MimeMessage) {
$html = (string) $body->getMessage();
} elseif ($body instanceof \Magento\Framework\Mail\EmailMessage) {
$html = (string) $body->getBodyText();
} else {
$html = (string) $body;
}
$htmlPart = new \Zend\Mime\Part($html);
$htmlPart->setCharset('utf-8');
$htmlPart->setEncoding(\Zend_Mime::ENCODING_QUOTEDPRINTABLE);
$htmlPart->setDisposition(\Zend_Mime::DISPOSITION_INLINE);
$htmlPart->setType(\Zend_Mime::TYPE_HTML);
$parts = [$htmlPart, $attachmentPart];
$bodyPart = new \Zend\Mime\Message();
$bodyPart->setParts($parts);
$message->setBody($bodyPart);
}
}
}
$transport->sendMessage();
}
}Finally, you add the following code in app/code/Vendor/Module/etc/di.xml to use the new TransportBuilder class of your module.
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="\Magento\Framework\Mail\Template\TransportBuilder" type="Vendor\Module\Model\Mail\TransportBuilder" />
</config>
