Yii2 ~ How do you setup Mpdf?

after installing Mpdf via composer. and reading the documentation over and over agian, I still don't understand how to use Mpdf...

could someone please tell me how this extention is used? maybe with some examples or maybe you have a great video tutorial I could use? the problem is that I need to use this extention for an assignment. otherwise I wouldn't even use it =)

~~~~~~EDIT~~~~~~

I guess I wasn't clear enough... this is the problem I have:

it reders like this:

Solution

If you haven't installed mPDF for Yii2 by Kartik-v, please install that one instead your current version. Here's the link: http://demos.krajee.com/mpdf#installation

They also wrote some great documentation and examples. Please follow them at their website: http://demos.krajee.com/mpdf#demo

In your controller:

//hint: add this after the controller namespace. (top of the file)
use kartik\mpdf\Pdf;

// Privacy statement output demo
public function actionMpdfDemo1() {
    $pdf = new Pdf([
        'mode' => Pdf::MODE_CORE, // leaner size using standard fonts
        'content' => $this->renderPartial('privacy'),
        'options' => [
            'title' => 'Privacy Policy - Krajee.com',
            'subject' => 'Generating PDF files via yii2-mpdf extension has never been easy'
        ],
        'methods' => [
            'SetHeader' => ['Generated By: Krajee Pdf Component||Generated On: ' . date("r")],
            'SetFooter' => ['|Page {PAGENO}|'],
        ]
    ]);
    return $pdf->render();
}

In any view file:

/**
 * THE VIEW BUTTON
 */
echo Html::a('<i class="fa glyphicon glyphicon-hand-up"></i> Privacy Statement', ['/site/mpdf-demo-1'], [
    'class'=>'btn btn-danger', 
    'target'=>'_blank', 
    'data-toggle'=>'tooltip', 
    'title'=>'Will open the generated PDF file in a new window'
]);

EDIT

You must create view file named privacy.php. and add it on the same folder as your previous view folder. write some html content on it, it shouldn't return crap.
