How to send two PDF files by mail?

Question

Yii

Hello, there is a function to convert html code to pdf file and send it:

public function actionSend($id)
    {
        $model = $this->findModel($id);
        $pdf = new Pdf([
            'mode' => Pdf::MODE_UTF8, // leaner size using standard fonts
            'content' => $this->renderPartial('act.php', [
                'model' => $this->findModel($id),
            ]),
            'cssFile' => '@vendor/kartik-v/yii2-mpdf/src/assets/kv-mpdf-bootstrap.css',
            'cssInline' => '.img-circle {border-radius: 50%;}',
            'options' => [
                'title' => 'Счёт',
                'subject' => 'Generating PDF files via yii2-mpdf extension has never been easy'
            ],
            'methods' => [
                'SetHeader' => ['Generated By: ARIANA WORLDWIDE||Generated On: ' . date("r")],
                'SetFooter' => ['|Page {PAGENO}|'],
            ]

        ]);
        //echo $this->render('act', ['model' => $model]);
        if ($id) {
            $content = $pdf->content;
            $filename = $pdf->filename;

            /*$mpdf = $pdf->getApi();
            $mpdf->WriteHtml($content);*/
            ob_clean();
            $path = $pdf->Output($content, Yii::getAlias('@root_folder') . '/frontend/uploads/' . $filename . 'Act.pdf', \Mpdf\Output\Destination::FILE);
            $sendemail = Yii::$app->mailer->compose()
                ->attach(Yii::getAlias('@root_folder') . '/frontend/uploads/' . $filename . 'Act.pdf')
                ->setFrom('[email protected]')
                ->setTo('[email protected]')
                ->setCc('[email protected]')
                ->setSubject('Счёт Alisa Market')
                ->send();
            if ($sendemail) {
                unlink(Yii::getAlias('@root_folder') . '/frontend/uploads/' . $filename . 'Act.pdf');
                return $this->render('act');
            }

        }

Now it is necessary to send two files, two different codes, but in one letter, how to do it?

Answer 1

Good afternoon.
Specify multiple attach()

$sendemail = Yii::$app->mailer->compose()
                ->attach(Yii::getAlias('@root_folder') . '/frontend/uploads/' . $filename . 'Act1.pdf')
                ->attach(Yii::getAlias('@root_folder') . '/frontend/uploads/' . $filename . 'Act2.pdf')
                ->attach(Yii::getAlias('@root_folder') . '/frontend/uploads/' . $filename . 'Act3.pdf')
               /* остальной код */

ps
Why create an extra alias '@root_folder'? Are the standard type aliases not enough for you @frontendor @webroot?

Take any ready-made class / library / component for sending mail from PHP, for example:
1. Swiftmailer
2. PHPMailer
3. php_libmail
As far as I remember, among other things, they allow you to attach any number of files to an e-mail letter (before sending it) .
