html2canvas- Take Screenshot of Web Page and Save It to Server (Javascript and PHP

FeedBack is important. Usually, end-users struggle to clarify their problems. And you might be unreachable for a phone call or remote connection.
That causes a huge need of visualization. First solution that appears in mind is to capture the current screen of user.
However, when I tried to implement that, it wasn’t so easy as I expected. Some old ways offer ActiveX but it seems too outdated. Since there’s a bridge needed between client side and server, JS libraries are the best way.
There’s a great library, html2canvas. It is told to be reverse-engineered version of Google Plus’ way of taking screenshots.
When I first discovered this library, it took me a while to use for simplest implementation. I just wanted to visualize a div element. However, there was no single page to tell the whole path to follow, thus I had to combine various sources.
Here’s how you can easily use for taking a screenshot of a div:
1- Import libraries
There are 3 libraries to import:
  • jquery.js
  • html2canvas.js
  • jquery.plugin.html2canvas.js
You can download html2canvas and html2canvas jQuery plugin from this link.
Note: The source link contains html2canvas v0.40. I recommend you to check for a newer version and use it instead from official html2canvas site.
I have used jquery.min.js v1.7.1 but you can try other versions. For this jQuery library, use this link.
Here’s first lines of code:
<script type="text/javascript" src="//"></script>
<script type="text/javascript" src="js/html2canvas.js"></script>
<script type="text/javascript" src="js/jquery.plugin.html2canvas.js"></script>
<!-- -->
2- Create your div
In my code, I used html2canvas for a div. You can use the whole body tag instead, it’s up to you.
Attach a div element to the page with a certain id:
<div id="target">
<!-- Render your page inside of this div. -->
3- Create a button and a hidden form
This part is important. In order to save the image to server, we need to pass captured image data with a form field.
In 4th step, you’ll see JavaScript code that writes the image data to hidden field and posts the form.
<input type="submit" value="Take Screenshot Of Div" onclick="capture();" />
<form method="POST" enctype="multipart/form-data" action="save.php" id="myForm">
    <input type="hidden" name="img_val" id="img_val" value="" />
4- JavaScript Code
function capture() {
        onrendered: function (canvas) {
            //Set hidden field's value to image data (base-64 string)
            //Submit the form manually
5- Use the posted values
Here I used a form to post the value. You can use Ajax calls or whatever. I have a PHP file, save.php. In this file, we will both show the picture and save it to the server.


        header("Content-Transfer-Encoding: binary");
        header("Content-Type: image/png");
        header("Content-Disposition: attachment; filename=custom-img.png");
