how to send mail using swiftmailer - Yii2 - php

Question

I tried to send email using swiftmailer in Yii2. I'm still beginner for this framework. This is my basic code:
public function sendMail($email)
{
if ($this->validate()) {
$email = Yii::$app->params['adminEmail'];
$mailto = 'user#gmail.com'; // need to change
$isi = "blablabla";
Yii::$app->mailer->compose("#app/mail/layouts/html", ["content" => $isi])
->setTo($mailto)
->setFrom($email)
->setSubject('coba')
->send();
return true;
}
return false;
}
In my case, I want to setup a 'setTo' based on my usr table. Field of my usr table:
id | username | manager | email | type |
1 | fauzi | arie | fauzi#gmail.com | user |
2 | arie | rian | arie#gmail.com | approver |
For example, when user with id = 1 login then he's create a new post and after click submit, the action also send email to user with id = 2 (manager of fauzi) for some review before post is publish to public. Thank you.

Answer 1

note: I assume your usr table has model called User if not, then change it to fit your code
you can provide also array of email adresses
like
->setTo(['email1#email.com', 'email1#email.com' => 'Name Surname'])
What you want to know is which users you want to get, maybe add some conditions to activerecord etc...
$users = User::find()->all();
or
// or any condition you need in your application, this is just example
$users = User::find()->andWhere(['type' => 'approver'])->all();
then Variant #1 you can loop trough all records
foreach ($users as $user) {
// you can add here some conditions for different types of users etc
// ... your code to send email ...
->setTo([$user->email => $user->username])
// or just
// ->setTo($user->email)
}
or Variant #2 you can get all emails first
$emails = \yii\helpers\ArrayHelper::getColumn($users, 'email');
// ... your code to send email ...
->setTo($emails)
// ...
