FuelPHP Postal

FuelPHP-Postal is designed as a fully featured wrapper to the Postal email sending platform.

Currently it handles sending emails, with or without attachments, stores the message ID returned from Postal in a database, and also exposes a webhook receiver to handle notifications from Postal that messages have been delivered, opened etc.

Installation

The recommended way to install fuelphp-postal is using Composer.

# Install Composer
curl -sS https://getcomposer.org/installer | php

Next, run the Composer command to install the latest stable version of fuelphp-postal.

php composer.phar require synergitech/postal

You will then need database tables for storing the outbound email details and webhook notifications. We have provided FuelPHP migrations to make this easy.

php oil r migrate --packages=postal

Configuration

You need to configure your app to point to your Postal instance and the address from which to send. A basic config looks like this:

return [
    'url' => 'https://yourpostal.io',
    'api_key' => 'ABCDEFGHI123456790',
    'send-name' => 'Your App Name',
    'send-address' => 'noreply@yourapp.io',
    'reply-to' => 'reply@yourapp.io',
    'template_html' => 'email/generic/html',
    'template_text' => 'email/generic/text'
];

The template_text and template_html will be used by default as the view files into which your $data array will be merged using FuelPHP's built in View render() function.

You will need to add postal to the config and package autoloaders to ensure they are available to your classes.

You can also define an environment variable in your .htaccess file to send all emails to one address which will help you develop your app.

SetEnv EMAIL you@company.io

You can also achieve this by adding a config value sendallmessagesto if you would rather not adjust your environment variables.

return [
    // ...
    'sendallmessagesto' => 'you@company.io'
    // ...
];

Quick Sending Messages

You can call the send() function to send an email. Arguments after $to are optional.

\Synergitech\Postal::send($subject, $body, $to, $to_name, $from, $data, $bcc);

Normal Sending Messages

If you want to access other features such as headers, attachments, and CC, you can forge() a new object which behaves similarly to Postals PHP library. The $data and $from arguments are optional.

$message = \Synergitech\Postal\SendMessage::forge($subject, $body, $data, $from);

Now you can use it to fill in the recipients and send. to(), cc(), and bcc() all function the same way.

$message->to('customer@example.com');
$message->cc('accounts@example.com', 'Accounts Department');

$message->bcc(array(
    'tom@example.com' => 'Tom',
    'dick@example.com' => 'Dick',
    'harry@example.com' => 'Harry'
));

$message->attach('report.pdf', 'application/pdf', file_get_contents('report.pdf'));

$message->send();

If you want to store your message contents in another view file, send a null body and a 'body_view' item in the $data array. The view will receive either an $is_text variable or an $is_html variable if you need to slightly differentiate between the two.

$message = \Synergitech\Postal\SendMessage::forge($subject, null, ['body_view' => $bodyview] + $data);

Webhooks

You can configure a webhook receiving URL within Postal. You need to create a controller within your FuelPHP project that calls:

\Synergitech\Postal\Webhook::ProcessWebhook();

Example Controller file (be sure to allow unauthenticated requests to pass to this function):

namespace Controller;

class Webhook extends \Controller_Rest
{
    public function action_postal()
    {
        \Synergitech\Postal\Webhook::ProcessWebhook();
    }
}

Logging

Using this package means you store a history of email messages and the webhooks let you keep updated with the status of those messages.

To make use of the messages as part of an audit trail, you will be interested in the database objects for the messages you have just sent.

You can set return_email_objects to true and any calls to send() will return an array of database objects which you can do with what you wish.

$sent = $message->send();

$log = \Model\Audit\Log::forge(array(
    // your specific information here
));

$log->save();

foreach ($sent as $email) {
    \Model\Audit\Item::forge(array(
        'log_id' => $log->id,
        'email_id' => $email->id
    ))->save();
}
