Email sending in the Yii framework: implementing email notifications

With the continuous development of the Internet, email has become an indispensable part of people's daily life and work. The use of email is not only in personal life, but also widely used in various enterprise applications. In scenarios such as registration or forgotten passwords, the email notification function is also used by more and more companies. The Yii framework provides a built-in email sending component, making the implementation of the email notification function more convenient.

Email sending in the Yii framework can be applied in various scenarios. For example, a website's new user registration needs to send a welcome email or activation link; an e-commerce website may need to send an order confirmation or delivery email; the company's workflow requires sending work arrangements or meeting notices, etc. In these scenarios, email sending is essential.

The email sending in the Yii framework uses the SwiftMailer email sending component. The steps to implement email sending are roughly as follows:

1. Configure email sending parameters

In the Yii framework, the configuration data for email sending can be specified in the configuration file, such as:

'components' => [
    'mailer' => [
        'class' => 'yiiswiftmailerMailer',
        'transport' => [
            'class' => 'Swift_SmtpTransport',
            'host' => 'smtp.gmail.com',
            'username' => 'username@gmail.com',
            'password' => 'password',
            'port' => '587',
            'encryption' => 'tls',
       ],
    ],
],

Here we give an example of using Gmail as an SMTP server. It should be noted that this method is only suitable for development environment, because the password in this method is stored in clear text. In a production environment we need to store passwords in configuration files or use other security mechanisms.

2. Writing email content

To send an email, you first need to prepare the content of the email. The email component in the Yii framework provides a variety of email types, including ordinary text emails, HTML emails, attachments, pictures, etc.

For a basic plain text email, you can use the following code:

use Yii;
use yiiaseInvalidParamException;
use yiiaseView;
use yiihelpersUrl;

class SomeClass {

  public function sendPlainTextEmail() 
  {
     $emailAddress = 'receiver@example.com';
     $name = 'Example Name';
     $subject = 'Email Subject';
     $body = 'Email Body';

     $mail = Yii::$app->mailer->compose()
         ->setTo($emailAddress)
         ->setFrom(['sender@example.com' => 'Example Name'])
         ->setSubject($subject)
         ->setTextBody($body);

     return $mail->send();
  }
}

The entire email sending process is constructed by the compose method.

In this example, the plain text content of the email body is set using the setTextBody method, and the email is set using the setSubject and setFrom methods subject and sender information. Specify the recipient's email address through the setTo method. Finally, call the send method to send the email.

3. Send Email

In addition to the above temporary parameter configuration and the way to write email content, we can also use ready-made template engines, such as Twig, etc. to write email HTML page and then pass it to the mailing component. For example:

$mail = Yii::$app->mailer->compose(
        ['html' => 'passwordResetToken-html', 'text' => 'passwordResetToken-text'],
        ['user' => $user]
    )
    ->setFrom([Yii::$app->params['supportEmail'] => Yii::$app->name . ' robot'])
    ->setTo($this->email)
    ->setSubject('Password reset for ' . Yii::$app->name)
    ->send();

The above code uses the values ​​of supportEmail and Yii::$app->name configured in the system parameters in the Yii framework as the sending email Part of the person's name and subject. Page settings come from HTML templates and plain text templates.

After the above three steps are completed, we can happily send emails. When developing web applications, effective email notification functions can help your company establish better customer communication and workflow. Through the above steps, you can easily implement the email sending function and achieve various purposes of interacting with users.
