How to delete the uploaded file from Dropzone.js using PHP

To delete an uploaded file from Dropzone.js using PHP, you need to follow these steps:

Step 1: Set Up Dropzone.js

First, set up Dropzone.js in your HTML file. Make sure you include the necessary JavaScript and CSS files. Here's a basic example of an HTML form with Dropzone.js:

<!DOCTYPE html>
    <title>Dropzone.js File Upload</title>
    <link rel="stylesheet" href="">
    <form action="upload.php" class="dropzone" id="myDropzone"></form>

    <script src=""></script>

Step 2: Handle File Uploads in upload.php

In your upload.php file (or any server-side script that handles file uploads), you will receive the uploaded file(s) and save them to your server. Additionally, you need to store information about the uploaded files in a database or somewhere else, depending on your application's requirements. Here's a basic example of handling file uploads in upload.php:

// Handle file upload
if (!empty($_FILES['file'])) {
    $uploadDir = 'uploads/'; // Directory where you want to save the uploaded files
    $uploadedFile = $_FILES['file'];

    // Generate a unique file name to avoid overwriting
    $uniqueFilename = uniqid() . '_' . $uploadedFile['name'];

    // Move the uploaded file to the destination directory
    $uploadPath = $uploadDir . $uniqueFilename;
    move_uploaded_file($uploadedFile['tmp_name'], $uploadPath);

    // Store information about the uploaded file (e.g., in a database)
    // Insert code to handle database storage here

// Respond to the client with the uploaded file details (e.g., the unique filename)
echo json_encode(['filename' => $uniqueFilename]);

Step 3: Delete Uploaded File Using PHP

To delete an uploaded file, you can create another PHP script, such as delete.php, that receives the filename as a parameter and deletes the corresponding file from the server. Here's an example of a delete.php script:

if (isset($_POST['filename'])) {
    $filename = $_POST['filename'];
    $filePath = 'uploads/' . $filename;

    if (file_exists($filePath)) {
        unlink($filePath); // Delete the file from the server
        echo json_encode(['message' => 'File deleted successfully']);
    } else {
        echo json_encode(['error' => 'File not found']);
} else {
    echo json_encode(['error' => 'Filename not provided']);

Step 4: Call delete.php from Dropzone.js

In your Dropzone.js configuration, you can add an event listener for file deletion. When a file is removed, you can call your delete.php script to delete the file from the server. Modify your HTML file as follows:

    // Initialize Dropzone
    var myDropzone = new Dropzone("#myDropzone", {
        url: "upload.php",
        paramName: "file",
        maxFilesize: 5, // Set your maximum file size
        addRemoveLinks: true // Enable the remove file link

    // Event handler for removing a file
    myDropzone.on("removedfile", function(file) {
        var filename =;

        // Call delete.php to delete the file from the server
        $.post("delete.php", { filename: filename }, function(response) {

In this code, we listen for the removedfile event in Dropzone.js and send an AJAX request to delete.php to delete the file from the server. Adjust the file paths and AJAX request parameters to match your directory structure and file naming conventions.

With these steps, you can implement file deletion for uploaded files in Dropzone.js using PHP. Be sure to handle errors and security considerations appropriately in your implementation.
