saving edited pdf to server with php

[Christian Joy Burgos]

is it possible to save edited pdfs to server through php?

You could call the following function from a WebViewer config file to get the PDF data as a blob. Once you have the blob you can refer to one of the many examples online of how to upload a blob to a server.

function uploadPDF() {

  var docViewer = readerControl.docViewer;

  var doc = docViewer.getDocument();

  var annotManager = docViewer.getAnnotationManager();

  docViewer.getAnnotationsLoadedPromise().then(function() {

    var options = { 'xfdfString': annotManager.exportAnnotations(), 'flags': CoreControls.SaveOptions.LINEARIZED };

    doc.getFileData(options).then(function (data) {

      var arr = new Uint8Array(data);

      var blob = new Blob([arr], {

        type: 'application/pdf'

      });

      // post blob to the url

    });

  });

}
