Yii2 - Generate Pdf on the fly and attach to email

Question

This is how I can generate pdf page

public function actionPdf(){
    Yii::$app->response->format = 'pdf';
    $this->layout = '//print';
    return $this->render('myview', []);
}

And this is how I send emails

$send = Yii::$app->mailer->compose('mytemplate',[])
    ->setFrom(Yii::$app->params['adminEmail'])
    ->setTo($email)
    ->setSubject($subject)
    ->send();

How I can generate pdf as a file and attach it to my emails on the fly?

Answer 1

Mailer have method called attachContent(), where you can put pdf file.

PDF should be rendered with output destination set as string, and then pass it as param to attachContent().

Sample:

Yii::$app->mail->compose()
   ->attachContent($pathToPdfFile, [
        'fileName'    => 'Name of your pdf',
        'contentType' => 'application/pdf'
   ])
   // to & subject & content of message
   ->send();

Answer 2

This is how I did it

In my controller:

$mpdf=new mPDF();
$mpdf->WriteHTML($this->renderPartial('pdf',['model' => $model])); //pdf is a name of view file responsible for this pdf document
$path = $mpdf->Output('', 'S'); 

Yii::$app->mail->compose()
->attachContent($path, ['fileName' => 'Invoice #'.$model->number.'.pdf',   'contentType' => 'application/pdf'])
