I am working on a module in which I need to attach an attachment with sales email. However, Magento 2.3 use zendframework2 so email attachment is not the same as zendframework1 (in Magento 2.2).

Can anyone help me to achieve the same task? How to implement attachment functions in Magento 2.3

I have searched in google and read several questions but I didn't find the solution.

I had the same issue.

To solve this i created a helper.

use MagentoFrameworkObjectManagerInterface;
use MagentoFrameworkMailMessageInterface;
use MagentoFrameworkMailTemplateFactoryInterface;
use MagentoFrameworkMailTemplateSenderResolverInterface;
use MagentoFrameworkMailTransportInterfaceFactory; 
use MagentoFrameworkMailTemplateTransportBuilder;

class UploadTransportBuilder extends TransportBuilder 

public function __construct(FactoryInterface $templateFactory,
 MessageInterface $message,
 SenderResolverInterface $senderResolver,
 ObjectManagerInterface $objectManager,
 TransportInterfaceFactory $mailTransportFactory) 
 parent::__construct($templateFactory,
 $message,
 $senderResolver,
 $objectManager,
 $mailTransportFactory);


public function attachFile(
 $body,
 $filename = null,
 $mimeType = Zend_Mime::TYPE_OCTETSTREAM,
 $disposition = Zend_Mime::DISPOSITION_ATTACHMENT,
 $encoding = Zend_Mime::ENCODING_BASE64
)

 $this->message->createAttachment($body, $mimeType, $disposition, $encoding, $filename);
 return $this;

Then I loaded this on my controller.

use BVZWishlistHelperUploadTransportBuilder;

UploadTransportBuilder $transportBuilder
$this->_transportBuilder = $transportBuilder

$transport = $this->_transportBuilder->setTemplateIdentifier('bvz_customer_wishlist')
 ->setTemplateOptions(['area' => 'frontend', 'store' => $store])
 ->setTemplateVars(['data' => $postObject])
 ->setFrom('support')
 ->addTo($formEmail, $customerName)
 ->attachFile($pdf,'Seleção de Produtos.pdf')
 ->getTransport();

$this->messageManager->addSuccess(__('Um e-mail foi enviado com sua lista de desejo.'));

 $transport->sendMessage();

The code method for attach a file is attachFile();
