Answers:
If you want to be more specific about encoding and page size, you can put those parameters when initializing mPDF class like this:
1 | $mpdf = new mPDF('utf-8', 'A4'); |
You can even specify actual page size in mm. In the example below the page size will be 190mm wide x 236mm height:
1 | $mpdf = new mPDF('utf-8', array(190,236)); |
If you want full functionality, you can even specify margins and if the page is landscape like this:
1 | $mpdf = new mPDF('', // mode - default '' |
2 | '', // format - A4, for example, default '' |
3 | 0, // font size - default 0 |
4 | '', // default font family |
5 | 15, // margin_left |
6 | 15, // margin right |
7 | 16, // margin top |
8 | 16, // margin bottom |
9 | 9, // margin header |
10 | 9, // margin footer |
11 | 'L'); // L - landscape, P - portrait |
Example
* First find required data
* Create php file receipt-print.php. This file used to display format for pdf file.
* Use renderPartial funtion to send values to display receipt-print.php and assign object to $html variable
* Create mpdf object assign parameters.
* Write html and create output.
public function actionPrintCommonReceipt($receipt_no, $ccid)
{
if(!yii::$app->user->can('view-receipt'))
{
throw new ForbiddenHttpException;
die();
}
$model = $this->findModel($receipt_no, $ccid);
$model->receipt_date=date('d-m-Y',strtotime($model->receipt_date));
$modelsReceiptitems = $model->receiptitems;
$student = $this->findStudentDetails($model->students_admission_number,$ccid);
$cent = Center::findone(['ccid'=>$ccid]);
$html = $this->renderPartial('receipt-print',[
'model' => $model,
'modelsReceiptitems' => $modelsReceiptitems,
'student' => $student,
'centerAddress'=>$cent['address'],
]);
//$imgSrc = Yii::$app->urlManager->createAbsoluteUrl('site/loadimage');
$mpdf = new mPDF('utf-8', 'A4',0,'',15,15,5,5,4,9,'P');
//$mpdf->WriteHTML('<watermarkimage src='.$imgSrc.' alpha="0.33" size="50,30"/>');
$mpdf->showWatermarkImage = true;
$mpdf->WriteHTML($html);
$mpdf->Output($title.'.pdf', "I");
}
