Below are listed the steps for you to follow when configuring the Kendo UI PDFViewer for PHP.
Step 1 Make sure you followed all the steps from the introductory article on Telerik UI for PHP—include the autoloader, JavaScript, and CSS files.
Step 2 Add the PDF.JS Processing scripts.
<script src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.2/pdf.js"></script>
<script>
window.pdfjsLib.GlobalWorkerOptions.workerSrc = 'https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.2/pdf.worker.js';
</script>
Step 3 Create a PDFViewer.
<?php
$pdfjs = new \Kendo\UI\PDFViewerPdfjsProcessing();
$pdfjs->file("../content/web/pdfViewer/sample.pdf");
$pdfViewer = new \Kendo\UI\PDFViewer('pdfViewer');
$pdfViewer->pdfjsProcessing($pdfjs);
?>
Step 3 Output the PDFViewer by echoing the result of the render method.
<?php
echo $pdfViewer->render();
?>
Reference
Client-Side Instances
You are able to reference an existing PDFViewer instance via the jQuery.data(). Once a reference is established, use the PDFViewer API to control its behavior.
<?php
$pdfjs = new \Kendo\UI\PDFViewerPdfjsProcessing();
$pdfjs->file("../content/web/pdfViewer/sample.pdf");
$pdfViewer = new \Kendo\UI\PDFViewer('pdfViewer');
$pdfViewer->pdfjsProcessing($pdfjs);
echo $pdfViewer->render();
?>
<script>
$(function() {
// The constructor parameter is used as the 'id' HTML attribute of the PDFViewer
var pdfViewer = $("#pdfViewer").data("kendoPDFViewer");
});
</script>
