Storing generated PDF files on the server

Question

Using the jsPDF plugin, I am creating a .pdf file and generating a download based on a button click. I would like to save the file onto my server i

If your PDF contains binary data, you can get into problems if you try to transfer the PDF via string. I used the blob output format of jsPDF with success.

var doc = new jsPDF();
// ... generate pdf here ...

// output as blob
var pdf = doc.output('blob');

var data = new FormData();
data.append('data' , pdf);

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
  if (this.readyState == 4) {
    if (this.status !== 200) {
      // handle error
    }
  }
}

xhr.open('POST', 'upload.php', true);
xhr.send(data);

Your upload.php can then use the $_FILES array in PHP
