Installation

composer require andrewdyer/slim3-mailer

Usage

Attach a new instance of Anddye\Mailer\Mailer to your applications container so it can be accessed anywhere you need. Mailer takes two arguements; an instance of Slim\Views\Twig and an optional array of SMTP settings.

$app = new \Slim\App;
    
$container = $app->getContainer();
       
$container['mailer'] = function($container) {
    $twig = $container['view'];
    $mailer = new \Anddye\Mailer\Mailer($twig, [
        'host'      => '',  // SMTP Host
        'port'      => '',  // SMTP Port
        'username'  => '',  // SMTP Username
        'password'  => '',  // SMTP Password
        'protocol'  => ''   // SSL or TLS
    ]);
        
    // Set the details of the default sender
    $mailer->setDefaultFrom('no-reply@mail.com', 'Webmaster');
    
    return $mailer;
};
    
$app->run();

If your application doesn't use Twig views already, you will need to also attach this to your container.

$container['view'] = function ($container) {
    $view = new \Slim\Views\Twig(__DIR__ . '/../resources/views');
    $basePath = rtrim(str_ireplace('index.php', '', $container['request']->getUri()->getBasePath()), '/');
    $view->addExtension(new \Slim\Views\TwigExtension($container['router'], $basePath));
    
    return $view;
};

Sending the Email (Basic Example)

$app->get('/', function (Request $request, Response $response) use($container) {
    $user = new stdClass;
    $user->name = 'John Doe';
    $user->email = 'johndoe@mail.com';
    
    $container['mailer']->sendMessage('emails/welcome.html.twig', ['user' => $user], function($message) use($user) {
        $message->setTo($user->email, $user->name);
        $message->setSubject('Welcome to the Team!');
    });
    
    $response->getBody()->write('Mail sent!');
    
    return $response;
});

welcome.html.twig

<h1>Hello {{ user.name }}</h1>
    
<p>Welcome to the Team!</p>
    
<p>Love, Admin</p>

Sending with a Mailable

Using mailable classes are a lot more elegant than the basic usage example above. Building up the mail in a mailable class cleans up controllers and routes, making things look a more tidy and less cluttered as well as making things so much more manageable.

Mailable classes are required to extend the base Anddye\Mailer\Mailable class;

use Anddye\Mailer\Mailable;

class WelcomeMailable extends Mailable
{
    
    protected $user;
    
    public function __construct($user)
    {
        $this->user = $user;
    }
    
    public function build()
    {
        $this->setSubject('Welcome to the Team!');
        $this->setView('emails/welcome.html.twig', [
            'user' => $this->user
        ]);
        
        return $this;
    }
    
}

Now in your controller or route, you set the recipients address and name, passing just a single argument into the sendMessage method - a new instance of the mailable class;

$app->get('/', function (Request $request, Response $response) use($container) {
    $user = new stdClass;
    $user->name = 'John Doe';
    $user->email = 'johndoe@mail.com';
    
    $container['mailer']->setTo($user->email, $user->name)->sendMessage(new WelcomeMailable($user));
     
    $response->getBody()->write('Mail sent!');
    
    return $response;
});
