Developing web applications often involves the need for sending emails - whether it's notifications to users, registration confirmations, or other communication purposes. The PHP framework Nette offers an elegant and efficient solution for this task. In this article, you'll learn how to create and manage emails in a Nette application.

Basics of Email Handling in Nette

Nette Framework provides the Nette\Mail\Message class, which is designed for composing email messages. This class allows you to set all standard headers and the body of the email, including attachments.

Creating a Simple Email

To create an email, first instantiate the Message object and set its basic attributes: subject, sender, recipient(s), and the body of the message.

$mail = new Nette\Mail\Message;
$mail->setFrom(This email address is being protected from spambots. You need JavaScript enabled to view it.')
     ->addTo(This email address is being protected from spambots. You need JavaScript enabled to view it.')
     ->setSubject('Test Email')
     ->setBody('This is a test email sent from a Nette application.');

Working with HTML Emails

If you want to send an HTML email, you can use the setHtmlBody method instead of setBody. This method allows you to include HTML code in the email, which will be correctly rendered in the recipient's email client.

$mail->setHtmlBody('<strong>This is an HTML email</strong> with <em>formatting</em> support.');

Sending Emails

For sending emails, Nette utilizes the Nette\Mail\SmtpMailer class, which handles communication with the SMTP server. The configuration of SmtpMailer is typically set in the application's configuration file (e.g., config.neon), where you specify the details for connecting to the SMTP server.

mail:
    smtp: true
    host: smtp.example.com
    username: This email address is being protected from spambots. You need JavaScript enabled to view it.
    password: secret
    secure: ssl

After configuring, you can send the email like this:

$mailer = new Nette\Mail\SmtpMailer($yourConfigArray);
$mailer->send($mail);

Working with emails in Nette Framework is straightforward and efficient thanks to well-designed classes and methods. By using Nette\Mail\Message for composing emails and Nette\Mail\SmtpMailer for sending them, you can seamlessly integrate email communication into your application. However, always remember to thoroughly test email sending to avoid delivery issues and spam.
