Simplon Email

This library helps to build emails by utilising SwiftMailer.

It enables the developer to send an email as plain/html version with automatic image detection/inline injection. It enforces template abstraction and offers injection of data.

Setup

Since its a composer package all you need to to do is require it within your composer package definitions and install/update it:

{
     "require": {
        "simplon/email": "*"
     }
}

If you dont know what composer is you should have a look at Composer's Webpage.

EmailTransportVo

This class holds our chosen email transport instance in order to send emails.

// php's internal mail
$emailTransportVo = (new \Simplon\Email\Vo\EmailTransportVo())->setTransportInstance(
	\Swift_MailTransport::newInstance()
);

// or via smtp transport
$emailTransportVo = (new \Simplon\Email\Vo\EmailTransportVo())->setTransportInstance(
	\Swift_SmtpTransport::newInstance('localhost', 25)
		->setUsername('foo')
		->setPassword('bar')
);

Email setup

Intro

We use builder pattern classes to define our email. It's really simple and helps us to stay in control of our data.

Building an email comes in two easy steps. The first step is about defining our email content with the help of templates. The second step defines the sender/recipient data as well as a subject.

Templates

All what is needed is to tell the class where to find our templates for this particular email. Templates are separated in two different types:

Base templates

NOT required
need to be named "base.plain" \ "base.html"

Example:

HEADER

#################################################

A base-template is the basis to all content-templates.
Content will replace the following placeholder:

{{content}}

#################################################

FOOTER

-------------------------------------------------

A base-template can read all injected
content variables, too. See below:

Today is {{date}}

Content templates

required
need to be named "content.plain" \ "content.html"

Oh herro!

This is a content template which can receive
content data such as the recipients name.

Be nice, {{name}}!

Thanks
Tino

PS: {{name}}'s age is {{age}}

Note: We enforce these names just to make it as easy and as quick as possible to setup your email.

Here is a snapshot from our test template folders which hold all data:

Create email

Alright, lets create our first email. Below we will set all relevant data. Just follow the example:

// set content data
$contentData = [
    'name' => 'Tino',
    'age'  => 32,
    'date' => date('r'),
];

```php
$emailVo = (new \Simplon\Email\Vo\EmailVo())
    ->setPathBaseTemplates(__DIR__ . '/templates/base') // optional
    ->setPathContentTemplates(__DIR__ . '/templates/content/tmpl01')
    ->setFrom($config['fromAddress'], $config['fromName'])
    ->setTo($config['toAddress'], $config['toName'])
    ->setSubject('Herro!')
    ->setContentData($contentData)

Send email

Almost done. Just pass our builder classes and the email is as good as gone :)

$response = (new \Simplon\Email\Email($emailTransportVo))->sendEmail($emailVo);

Complete example

See the following complete example of sending an email.

require __DIR__ . '/../vendor/autoload.php';

// load test data
require __DIR__ . '/config.php';

// ##########################################

// set content data
$contentData = [
    'name' => 'Tino',
    'age'  => 32,
    'date' => date('r'),
];

// set email
$emailVo = (new \Simplon\Email\Vo\EmailVo())
    ->setPathBaseTemplates(__DIR__ . '/templates/base')
    ->setPathContentTemplates(__DIR__ . '/templates/content/tmpl01')
    ->setFrom($config['fromAddress'], $config['fromName'])
    ->setTo($config['toAddress'], $config['toName'])
    ->setSubject('Herro!')
    ->setContentData($contentData);

// ------------------------------------------

// set transport
$emailTransportVo = new \Simplon\Email\Vo\EmailTransportVo(
	\Swift_MailTransport::newInstance()
);

// ------------------------------------------

// send email
$response = (new \Simplon\Email\Email($emailTransportVo))->sendEmail($emailVo);

// BOOL to indicate if all went fine
var_dump($response);

Anything else?

Still in doubt how to use this library? Have a look at the test folder.
