Dropzone Add Download Button

If you're using Dropzone.js to upload files, you may want to add a download button to your uploaded files. This can be easily achieved by adding a button element to the template that displays the uploaded file.

Method 1: Adding a Button to the Template

To add a download button to the template, you need to modify the Dropzone options when initializing it. Here's an example:

Dropzone.options.myDropzone = {
  init: function() {
    this.on("success", function(file, response) {
      var downloadButton = Dropzone.createElement("<button>Download</button>");
      var downloadUrl = "https://example.com/download/" + response.filename;
      downloadButton.addEventListener("click", function() {
        window.location.href = downloadUrl;

In this example, we're adding a download button to the previewElement of each successfully uploaded file. We're also defining the URL that the button should open when clicked, which includes the filename returned by the server as response.filename.

Method 2: Using a Data Attribute

If you don't want to modify the Dropzone options, you can add a data attribute to the template that contains the download URL. Here's an example:

<div class="dz-preview dz-file-preview">
  <div class="dz-details">
    <div class="dz-filename"><span data-dz-name></span></div>
    <div class="dz-size" data-dz-size></div>
  <div class="dz-progress"><span class="dz-upload" data-dz-uploadprogress></span></div>
  <div class="dz-success-mark"><span></span></div>
  <div class="dz-error-mark"><span></span></div>
  <div class="dz-error-message"><span data-dz-errormessage></span></div>
  <button class="download-button" data-downloadurl="https://example.com/download/filename.ext">Download</button>

In this example, we're adding a data-downloadurl attribute to the download button that contains the URL to download the file. You can replace the URL with a variable that contains the download URL generated by your backend.

Whichever method you choose, be sure to test your implementation thoroughly to ensure that it works as expected.
