24. Back to the basics... part 4/n Fabien Potencier @fabpot
25. 4) Symfony MIME Everything you need to create beautiful emails Fabien Potencier @fabpot
26. Symfony Mime
27. use Symfony\Component\Mime\Email; $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text('Some text message') ->html('<b>Some HTML message</b>') ->attach('doc.txt') ; The basics
28. $email = (new Email()) ->from('fabien@symfony.com') ->to(new Address('fabien@sensiolabs.com')) ->addTo(new NamedAddress('fabien@sensiolabs.com', 'Fabien')) ->addCc('thomas@symfony.com', 'lucas@symfony.com') ->addCc(...['thomas@symfony.com', 'lucas@symfony.com']) ->subject('Some subject') ->text('Some text') ; from, to, cc, bcc
29. $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text('Some text message') ->html('<b>Some HTML message</b>') ; echo strlen(serialize($email)); Email is a data object Only 2k vs 16k for Swiftmailer
30. Why is it so different
 from Swiftmailer?
31. $email = (new Email()) ->text('Some text message') ->html('<b>Some HTML message</b>') ; $email = (new \Swift_Message()) ->setBody('Some text message') ->addPart('<b>Some HTML message</b>', 'text/html') ; A better data object model 16k serialized 38 objects complex serialization "fixed" headers 2k serialized 7 objects simple serialization "dynamic" headers
32. echo $email->toString(); sleep(2); $email->to('helene@symfony.com'); echo $email->toString(); Fixed vs dynamic headers Different
 set of headers Date, Boundary, Message-ID
33. $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text(fopen('email.txt', 'r')) ->html(fopen('email.html', 'r')) ; echo $email->toString(); foreach ($email->toIterable() as $chunk) { echo $chunk; } String or resources, your choice
34. // Email extends Message use Symfony\Component\Mime\Message; use Symfony\Component\Mime\Part\TextPart; use Symfony\Component\Mime\Header\Headers; $body = new TextPart('Some content'); $headers = (new Headers()) ->addMailboxListHeader('From', ['fabien@symfony.com']) ->addMailboxListHeader('To', ['fabien@sensiolabs.com']) ->AddTextHeader('Subject', 'Some subject') ; $email = new Message($headers, $body); And you get full control!
35. $txt = new TextPart('Some content'); $html = new TextPart('<b>Some content</b>', 'html'); $body = new AlternativePart($txt, $html); $email = new Message($headers, $body); Get creative
36. A "complete" email multipart/mixed | |------------> multipart/related | | | |------------> multipart/alternative | | | | | ------------> text/plain | | | | | ------------> text/html | | | ------------> image/png | ------------> application/pdf ->text() ->html() ->embed() ->attach()
37. $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->setBody($body) ; Mix several approaches
38. $email ->attach('Some content', 'doc.txt', 'text/plain') ->attachFromPath('/path/to/doc.txt') ->attach(fopen('doc.txt', 'r'), 'doc.txt', 'text/plain') ; Attachments
39. $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text('Some text') ->html('<b>The new logo: <img src="cid:logo.jpg"></b>') ->embedFromPath('logo-small.jpg', 'logo.jpg') ; Embeds
40. // Email extends Message extends RawMessage use Symfony\Component\Mime\RawMessage; $message = new RawMessage($email->toString()); $message->toString(); Go raw! Serialize an email as a string instead of a PHP object
41. Creating Emails with Twig Twig is perfect for emails aka, Twig is not dead and still very useful :)
42. use Symfony\Bridge\Twig\Mime\Renderer; use Symfony\Bridge\Twig\Mime\TemplatedEmail; use Twig\Environment; use Twig\Loader\FilesystemLoader; use Symfony\Component\Mime\NamedAddress; $twig = new Environment($loader = new FilesystemLoader(__DIR__.'/templates')); $loader->addPath(__DIR__.'/images', 'images'); $email = (new TemplatedEmail()) ->from('fabien@symfony.com') ->to(new NamedAddress('fabien@sensiolabs.com', 'Fabien')) ->text('Some text content') ->htmlTemplate('simple.html.twig') ->context([ 'city' => 'Lille' ]) ; $renderer = new Renderer($twig); echo $renderer->render($email)->toString(); Native integration with Twig
43. <p> Welcome <b>{{ email.toName }}</b> from {{ city }}! </p> <p> <img src="{{ email.image('@images/photo.jpg') }}"> </p> Native integration with Twig Symfony\Bridge\Twig\Mime\ WrappedTemplatedEmail Twig template name Template context
44. {% do email.attach('@docs/doc.pdf') %} <p> Welcome <b>{{ email.toName }}</b>! </p> <p> <img src="{{ email.image('@images/photo.jpg') }}"> </p> Native integration with Twig
45. {% do email.priority(5) %} <p> Welcome <b>{{ email.toName }}</b>! </p> <p> <img src="{{ email.image('@images/photo.jpg') }}"> </p> Native integration with Twig
46. $email = (new TemplatedEmail()) ->from('fabien@symfony.com') ->to(new NamedAddress('fabien@sensiolabs.com', 'Fabien')) ->textTemplate('simple.txt.twig') ->htmlTemplate('simple.html.twig') ; Native integration with Twig
47. $email = (new TemplatedEmail()) ->from('fabien@symfony.com') ->to(new NamedAddress('fabien@sensiolabs.com', 'Fabien')) ->template('simple.email.twig') ; Native integration with Twig
48. {% block config %} {% do email.attach('@images/planfaidherbe.jpeg') %} {% endblock %} {% block subject %}Email Subject{% endblock %} {% block text %} Optional text representation {% endblock %} {% block html %} <p>Welcome <b>{{ email.toName }}</b>!</p> <p><img src="{{ email.image('@images/photo.jpg') }}"></p> {% endblock %} Native integration with Twig
49. {% block text %} {% set formula = "2 > 1?" %} {% autoescape false %} {{ formula }} {% endautoescape %} {% endblock %} {% block html %} {% set formula = "2 > 1?" %} {{ formula }} {% endblock %} Native integration with Twig HTML escape by default with the "name" strategy From: fabien@symfony.com To: Fabien <fabien@sensiolabs.com> MIME-Version: 1.0 Date: Thu, 28 Feb 2019 12:10:16 +0100 Message-ID: <7885775f35b0509444e99290be3216e2@symfony.com> Content-Type: multipart/alternative; boundary="_=_symfony_1551352216_9df84f01f42af586d65b48578466206f_= --_=_symfony_1551352216_9df84f01f42af586d65b48578466206f_=_ Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable =20 2 > 1? =20 --_=_symfony_1551352216_9df84f01f42af586d65b48578466206f_=_ Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: quoted-printable =20 2 &gt; 1? --_=_symfony_1551352216_9df84f01f42af586d65b48578466206f_=_--
50. Tip! If the Text part is empty, the Renderer automatically generates one
51. But HTML in emails is hard Compatibility with email clients Inline CSS Responsive layout …
52. use Twig\CssInliner\CssInlinerExtension; $twig->addExtension(new CssInlinerExtension()); {% filter inline_css %} <style> b { color: red } </style> <p> Welcome <b>{{ email.toName }}</b>! </p> {% endfilter %} Inlining CSS
53. {% filter inline_css("@css/email.css") %} <style> b { color: red } </style> <p> Welcome <b>{{ email.toName }}</b>! </p> {% endfilter %} Inlining CSS
54. use Twig\Markdown\MarkdownExtension; $twig->addExtension(new MarkdownExtension()); <p> {% filter markdown %} | Version | LTS? | Latest | | ------------- |:-------------:| -------:| | 1.0 | Yes | 1.0.1 | | 2.1 | No | 2.1.33 | {% endfilter %} </p> Use Markdown to simplify your templates
55. use Twig\Inky\InkyExtension; $twig->addExtension(new InkyExtension()); Use Inky to simplify your HTML https://foundation.zurb.com/emails.html
56. {% filter inky|inline_css(source("@zurb/stylesheets/main.css")) %} <container> <row class="header"> <columns> <spacer size="16"></spacer> <h4 class="text-center">Symfony Connect</h4> </columns> </row> <row> <columns> <spacer size="32"></spacer> <center><img width="100px" src="{{ email.image("@images/symfony.png") }}"></center> <spacer size="16"></spacer> <h1 class="text-center">Forgot Your Password?</h1> <spacer size="16"></spacer> <p class="text-center">It happens. Click the link below to reset it.</p> <button class="large expand" href="#">Reset Password</button> <hr/> <p><small><center><a href="#">unsubscribe here</a>.</small></center></p> </columns> </row> </container> {% endfilter %} Use Inky to simplify your HTML
