Email functionality is the most requested feature in a web framework. FuelPHP provides an elegant email class bundled as a package. It is used to send simple plain text email as well as advanced rich text email with multiple attachments. It supports the following features - Plain-text mails, HTML mails, attachments, and inline attachments.

Configuration

To enable email functionality in the application, we need to just load the email package as specified below in the main configuration file, fuel/app/config/config.php.

'always_load' => array ( 
   'packages' => array ( 
      'email', 
   ), 
),

Another option is to load the email package, the controller itself as follows.

\Package::load('email');

The email setting can be done in the main configuration file and some of the important options are as follows,

  • driver − Email driver such as smtp

  • is_html − Whether to send mail as HTML content or not

  • priority − Priority of the email

  • smtp.host − SMTP server host

  • smtp.port − SMTP server port

  • smtp.username − SMTP server username

  • smtp.password − SMTP server password

  • smtp.timeout − SMTP timeout

  • smtp.starttls − Whether the SMTP server needs STARTTLS command
