Create Drag and Drop Multiple File Upload using PHP and Dropzone.js

Image uploading is one of the most common features every website owner would love to have in their website. I have also posted the script to upload images in PHP and its enhanced version. Users must be able to upload multiple image files easily. I just came to know about a wonderful js library dropzone.js. You can use it with php and create easy-to-use multiple file uploader in minutes. In this tutorial I will show you how to do that.   We will allow users to add multiple images just by dragging it in into our file uploader page.

This tutorial requires dropzone.js you can download it from its official website (Everything is well explained). I have used dropzone.js version 3.0 (latest till date) in this tutorial.

multiple file uploader


Now let’s start our tutorial, we have just two mail files here index.html  and file-upload.php. index.html file is a simple file which contains call to dropzone.js and css file then it has code to show up the simple form.  File-upload.php handles rest of the part, it uploads images to specified directory in server.

Note: I have used style sheet given by dropzone, you can download the zip file from here. But I have uploaded the minimal files required for this tutorial so you can download that too.

You just need a form in index.html, here is the main code:

<form action="file-upload.php" class="dropzone"></form>
<p style="text-align: justify;">

Code for file-upload.php:


$upload_dir = 'myuploads';

if (!empty($_FILES)) {

 $tempFile = $_FILES['file']['tmp_name'];
 // using DIRECTORY_SEPARATOR constant is a good practice, it makes your code portable.
 $targetPath = dirname( __FILE__ ) . DIRECTORY_SEPARATOR . $upload_dir . DIRECTORY_SEPARATOR;
 // Adding timestamp with image's name so that files with same name can be uploaded easily.
 $mainFile = $targetPath.time().'-'. $_FILES['file']['name'];


<p style="text-align: justify;">

Its really easy to implement this tutorial, and it will hardly take your 10 minutes. We can expect a lot more from future versions of dropzone.js. Still there’s a lot that should be done like giving option to delete files after upload etc. Share this simple tutorial with your friends, I hope it will help them too.

Note: You should use restriction on the type of file to be uploaded on server. Based on your need allow only files of particular type to be uploaded.

  1. Hi!, big thanks! This tute is very helpfull. Just a little question. How could you store the images name in a MySQL database?

          1. Hi Jonathan,
            You can use this script to upload your images in a directory in your server. Add few lines of PHP code which will store path of image files in database. Remember to put restriction (by file type) so that this code will allow only images to be uploaded on server, by default it allows all type of files so your users can upload any malicious file.


  2. Hi thank you. That helps me a lot. Sorry my bad english- I’m from Germany 😉

    I have one problem, maybe you can help me.
    In the “file-upload.php” you are writing :
    “// Adding timestamp with image’s name so that files with same name can be uploaded easily.”

    But I need that without the timestamp and I don`t know how.
    Can you help me, please?

    1. Hi Lukas,

      Change this line

      $mainFile = $targetPath.time().’-‘. $_FILES[‘file’][‘name’];


      $mainFile = $_FILES[‘file’][‘name’];

  3. Hi!, big thanks! This tute is very helpfull. Just a little question. How could you store the images name in a MySQL database? Could you give an example? Because I tried unsuccessfully to do…

    1. Hi Miguel,

      You can simply store filename with path in your MySQL database like this
      $image_path = “UPLOAD_DIRECTORY_PATH”.$_FILES[“file”][“name”]; (replace ‘UPLOAD_DIRECTORY_PATH’ with actual path)
      Then store $image_path in MySQL database just like you store any other variable.

      1. i upload multiple file and i want to store that all file name in one coloumn in database. when i insert filename in database ,if i upload two file then they insert in different coloumn.solve please,i know i m doing silly mistake but i m not cathing that.

  5. Hi sanjeev,

    thanks for your answer! but its not working. you wrote me, that I have to:

  12. I have subscribed already. but it says that My Email id is not on the list. On another side, I saw , emails are being uploaded after 12 hours. Sad

  13. Hi, I use the Dropzone.js in my project and I use it to list and upload files, but when I upload the files I change the name of file and create one event to open the file uploaded in new tab. The problem is, the link to open the file, because in “addedfile” function the is the original, but I need to create a link to server file, that now have a new name.

    What I did was, on “addedfile” function create one event with link to (because it’s mandatory to list files) with next code:
    file.previewElement.addEventListener(“click”, function() {“uploads” +, ‘_blank’);

    and then, on “success” function I try to change this event with same code, but it add a new link, and open 2 new tabs, one with original filename and other with the new name (the correct name).

    My question is: How to change the EventListner, instead create a new link (removeEventListner(…) is not working), or in “addedfile” function save this new name on Dropzone plugin (in “addedfile” function the code = “abc.docx” is not working)?

    Thanks in advance.
