php - How do you send an email in Shopware 6 controller?

Solution:

Within Shopware 6 you also have the Mailservice which provides you a send() method.

So basically a really simple example to use the service would be:

public function __construct(
    MailServiceInterface $mailService,
) {
    $this->mailService = $mailService;
}

private function sendMyMail(SalesChannelContext $salesChannelContext): void
{
    $data = new ParameterBag();
    $data->set(
        'recipients',
        [
            '[email protected]' => 'John Doe'
        ]
    );

    $data->set('senderName', 'I am the Sender');

    $data->set('contentHtml', 'Foo bar');
    $data->set('contentPlain', 'Foo bar');
    $data->set('subject', 'The subject');
    $data->set('salesChannelId', $salesChannelContext->getSalesChannel()->getId());

    $this->mailService->send(
        $data->all(),
        $salesChannelContext->getContext(),
    );
}
Copy code

Make also sure to tag the service within yourservices.xml.

<service id="Your\Namespace\Services\YourSendService">
  <argument id="Shopware\Core\Content\MailTemplate\Service\MailService" type="service"/>
</service>
Copy code

Email Template

If you want to use Email Templates, there is also a how-to add a mail template in a plugin

If you have an email template, you need to fetch it before sending the email. Then you're able to get the content from your email template to pass those values to thesend() method.

private function getMailTemplate(SalesChannelContext $salesChannelContext, string $technicalName): ?MailTemplateEntity
{
    $criteria = new Criteria();
    $criteria->addFilter(new EqualsFilter('mailTemplateType.technicalName', $technicalName));
    $criteria->setLimit(1);

    /** @var MailTemplateEntity|null $mailTemplate */
    $mailTemplate = $this->mailTemplateRepository->search($criteria, $salesChannelContext->getContext())->first();

    return $mailTemplate;
}
Copy code

You can later than set those Email values which are coming from your Email template (which is also available within the administration ) instead of hardcoding it within your send method.

$data->set('contentHtml', $mailTemplate->getContentHtml());
$data->set('contentPlain', $mailTemplate->getContentPlain());
$data->set('subject', $mailTemplate->getSubject());
