how to upload pdf to server from ajax data send (using jsPDF)

Question

I'm using jsPDF to generate a pdf on client-side. With the function doc.save('filename.pdf') I can download it. Now I need to save it on the server, so I'm sending the pdf data with .ajax() and receiving it with a PHP script but the images on the generated pdfURL doesn't show (http://mydomain/tmp/test.pdf); only shows the text.

Can you give me a hand please?

My js code:

//doc.save('test.pdf');  WORKS WELL
var pdf = doc.output();
$.ajax({
  method: "POST",
  url: "inc/test.php",
  data: {data: pdf},
}).done(function(data){
   console.log(data);
});

The PHP script:

<?php
if(!empty($_POST['data'])){

    $data = $_POST['data'];
    print_r($data);

    file_put_contents( "../tmp/test.pdf", $data );
} else {
    echo "No Data Sent"; 
}
exit();
?>

This is the pdf generated after the php scripting proccess: http://control.edge-cdn.com.ar/tmp/test.pdf

And this is the generated with the doc.save() function: http://control.edge-cdn.com.ar/repo/all.pdf Regards!

SOLUTION:

I was trying to send the pdf data as binary. I just base64 encode the string, send it and them decode that on the php.

JS:

    var pdf = btoa(doc.output()); 
    $.ajax({
      method: "POST",
      url: "inc/test.php",
      data: {data: pdf},
    }).done(function(data){
       console.log(data);
    });

PHP:

if(!empty($_POST['data'])){
$data = base64_decode($_POST['data']);
// print_r($data);
file_put_contents( "../tmp/test.pdf", $data );
} else {
echo "No Data Sent";
}
exit();
