Elegant File Input Enhancement Plugin With JavaScript – filepond

Description:

filepond is a JavaScript file upload plugin which helps you create elegant, flexible, customizable, drag-and-drop file input on the web page. Also features file preview, multi-file upload, server-side processing and much more. Licensed under GPL 3.0.

Basic usage:

Include the filepond’s stylesheet ‘filepond.css’ and JavaScript ‘filepond.js’ on the html page.

<link href="filepond.css" rel="stylesheet">
<script src="filepond.js"></script>

Create the file upload field on the webpage as these:

<div class="demo" id="demo">

  <div class="filepond-ripple filepond-ripple-one"></div>
  <div class="filepond-ripple filepond-ripple-two"></div>
  <div class="filepond-ripple filepond-ripple-three"></div>

  <div class="filepond-wrapper">

    <input type="file" 
        name="filepond" 
        multiple 
        data-max-total-files="10" 
        data-max-file-size="3MB"/>

  </div>

</div>

Initialize the plugin and done.

var pond = FilePond.create( document.querySelector('input[type="file"]') );

Override the default options to customize the file uploader.

FilePond.setOptions({
