Yii Framework 2 : Create PDF Files Using mPDF

Now go to 'vendor/composer/autoload_namespaces.php' file and add the below line into array

'mPDF' => array($vendorDir . '/mpdf/mpdf'),

Note: Manual configuration will be automatically removed If you update the composer.json. Be careful on composer handling.

Create PDF Using mPDF

Now I will create a function called 'createMPDF' in sitecontroller.php and will make it as pdf file.

SiteController.php

<?php
//...............
use app\models\ContactForm;
use mPDF;
class SiteController extends Controller
{
    //...............
    public function actionCreateMPDF()
    {
        $mpdf = new mPDF();
        $mpdf->WriteHTML($this->renderPartial('mpdf'));
        $mpdf->Output();
        exit;
        //return $this->renderPartial('mpdf');
    }
    public function actionSamplePdf()
    {
        $mpdf = new mPDF;
        $mpdf->WriteHTML('Sample Text');
        $mpdf->Output();
        exit;
    }
    public function actionForceDownloadPdf()
    {
        $mpdf = new mPDF();
        $mpdf->WriteHTML($this->renderPartial('mpdf'));
        $mpdf->Output('MyPDF.pdf', 'D');
        exit;
    }
    //...............
}
?>
