README
This is a little mail plugin that contains:
- SMTP plugin wrapper
- easily send plain text, html or both text & html hybrid content mails
- convenient methods to add one or multiple recipients
- encode special chars for mails with ISO charset
- ping and jump methods for tracking read and click events in your html mails
- save mails as files to disk
Getting started
This plugin is configurable via config file:
[mailer] ; smtp config smtp.host = smtp.domain.com smtp.port = 25 smtp.user = info@domain.com smtp.pw = 123456789! ; scheme could be SSL or TLS smtp.scheme = ; optional mail settings from_mail = noreply@domain.com from_name = Mario Bros. ; mail to receive bounced mails errors_to = bounce@domain.com ; used mail for replies to the sent mail reply_to = info@domain.com ; handler for SMTP errors on.failure = \Controller\Mail::logError ; handler for tracing opened mails on.ping = \Controller\Mail::traceMail ; handler for redirecting jump links on.jump = \Controller\Mail::traceClick ; automatically create jump links in all <a> tags jumplinks = true ; path for storing mail dumps storage_path = logs/mail/
Usage
A little sample looks like this:
function send_test($email, $title=null) { $mail = new \Mailer(); $mail->addTo($email, $title); $mail->setText('This is a Test.'); $mail->setHTML('This is a <b>Test</b>.'); $mail->send('Test Mail Subject'); }
If you want, you can change the encoding type that is used for the email body and header when instantiating the mail object with a constructor argument:
$mail = new \Mailer('UTF-8'); // default $mail = new \Mailer('ISO-8859-1'); $mail = new \Mailer('ISO-8859-15');
Tracking
To initialize the tracking routes, call this before $f3->run()
:
$f3->config('mailer_config.ini'); // ... Mailer::initTracking(); // ... $f3->run();
To add the ping tracking pixel (1x1 transparent 8bit PNG), put this in your html mail body:
<img src="http://mydomain.com/mailer-ping/AH2cjDWb.png" />
The file name should be a unique hash you can use to identify the recipient who read your mail.
The tracking methods could look like this:
static public function logError($mailer, $log) { $logger = new \Log('logs/smtp_'.date('Y_m_d').'.log'); $logger->write($log); } static public function traceMail($hash) { // your mail $hash is being read } static public function traceClick($target) { // someone clicked $target link }
Mock & Storage
In case you don't want to actually send the email, but just want to run a test flight and save the mail in a text file, you can mock the server dialog:
$mail->send($subject, TRUE); // mock call $mail->save('newsletter.eml'); // save to file in 'mailer.storage_path' directory $mail->reset();
If you want to keep using the object after a mock call, you need to reset the mailer and add recipients, content and attachments again.
The mail file includes all file attachments.
Logging
You can log the full SMTP server dialog after sending the email. This could be useful for debugging purposes or as a sending confirmation.
$success = $mailer->send($subject); $f3->write('SMTP_mail.log', $this->mailer->log());
Notice: By default, the log level is verbose
, which means it also contains the mail body and attachments, which might eat up a lot of memory.
To reduce the log level, set $log
to TRUE
(dialog only) or FALSE
(disabled) in:
$mailer->send($subject, $mock, $log);
Keep in mind that when you write down mails to files, it can only store what was found in the SMTP log, hence it only works when logging level is verbose
.
