Mailing

Extension for Nette Framework: Easy & object-oriented way of sending & logging mails

Mailing extension lets you send/log emails in the object oriented world.

Overview

Downloading Mailing

Mailing is available through composer package ublaboo/mailing:

composer require ublaboo/mailing

MailFactory

MailFactory gives you a way to create your mails instances. In the background it sets some parameters, decides whether to log and email or not, tries to find mail template etc.

Mail is the base class you will extend in each of your email cases (classes). In your particular mail class you will set email senders/recipients/cc/.., basepath (if you want to send inline images), attach files, etc. There are also available config parameters (if you have put them in there through config.neon).

You will send it via Mail::send() method.

Create mail class

Once you have registered mailing extension, you can create new mail class and then get MailFactory from DIC to send it:

namespace App;

use Nette;
use Ublaboo\Mailing\Mail;
use Ublaboo\Mailing\IComposableMail;

class ContactMail extends Mail implements IComposableMail
{

	/**
	 * There you will always have your mail addresses from configuration file
	 * @var array
	 */
	protected $mails;


	public function compose(Nette\Mail\Message $message, $params = null)
	{
		$message->setFrom($this->mails['default_sender']);
		$message->addTo($params['recipient']);
	}
}

use Nette;
use Ublaboo;

class HomepagePresenter extends Nette\Application\UI\Presenter
{

    /**
     * @var Ublaboo\Mailing\MailFactory
     * @inject
     */
    public $mailFactory;


    public function actionDefault()
    {
        $params = ['recipient' => 'hello@hello.hello'];
        $mail = $this->mailFactory->createByType('App\Mailing\ContactMail', $params);
    }
}

Send it!

# ...

$mail = $this->mailFactory->createByType('App\Mailing\ContactMail', $params);
$mail->send();

Pass parameters to the mail

You see the $params variable? That variable is passed to the ::compose() method of you mail class. And also it is passed into mail template, exapanded of course. So, say you pass parameters (below) to $mailFactory, you will be able to use $recipient and $name in your mail template.

$params = [
    'recipient' => 'john@doe.example',
    'name' => 'John Doe'
];

Example mail template:

<!DOCTYPE html>
	<html>
	<head>
		<title>Contact mail</title>
	</head>
	<body>
	    Helo, {$name}
	    <br>
	    Your email is: {$recipient}
	</body>
</html>

Mail templates

Now, there is some convention in directory structure and you should stick to it. It doesn't matter where you put your mails, but the Mail class (which your mails will inherit from) will look for template latte files in <same_directory_as_your_mails_are</templates. The name of particular template has to be in camel_case naming convention. E.g.:

app/
	Mailing/
		ContactMail.php
		templates/
			contact_mail.latte

But that is only a recommendation. You can always change your template file path by Mail::setTemplateFile(). Eg:

# ...

public function compose(Nette\Mail\Message $message, $params = NULL)
{
	# ...
	
	$this->setTemplateFile(__DIR__ . '/templates/contact_mail.latte');
}

Or from the outside:

# ...

$mail = $mailFactory->createByType('App\Mailing\ContactMail', ['recipient' => 'hello@hello.hello']);
$mail->setTemplateFile('super_awesome_template.latte');

No templates

Of course you don't have to send mails with templates, you can just use plaintext mail body. You would do that probably in your mail class:

# ...

public function compose(Nette\Mail\Message $message, $params = NULL)
{
	# ...
	
	$message->setBody('Hello');
}

Configuration

There are some configuration options available like whether to log (or send, or both), where to log, where to find inline images from, etc

Start with registering extension in config.neon:

extensions:
	mailing: Ublaboo\Mailing\DI\MailingExtension

There are several config options:

mailing:
	do: both # log|send|both
	log_directory: '%appDir%/../log/mails' # this is default option
	mail_images_base_path: %wwwDir% # this is default option
	mails: []

Let's discuss each of these options:

In this option you may choose between these three directives:

log means all mails will be just stored on local disk in log directory. All mails are saved in .eml format (with possible images and attachments)
send will only send all mails, but not log
both will do both

log_directory

That one is pretty obvious. Directory, where mail files (.eml) will be stored.

mail_images_base_path

This is the path, where Nette\Mail\Message will look for all images that can be inline embedded in mail.

mails

This array filled with your parameters (probably mail addresses - like recipients, senders, etc) will be available in instance of each of your mail class (read more) so that you can easily set sender and recipient, bcc, cc or whatever you need for particular mail.

E.g.:

mailing:
	mails: [
		default_sender: foo@bar.baz
	]

Log

By default, MailLogger is logging all sent Mails in log directory in format ///<mail_name.eml>. As you can see, the .eml extension is used to easily open an email file in all desktop clients.
