How to use dropzonejs with PHP for uploads?

By using DropzoneJS with PHP, we can easily implement drag and drop file upload feature in our existing website. DropzoneJS is an open source library which provide us drag and drop file uploads with live image preview on web page before upload image to server.

DropzoneJS provides an easy way to integrate drag and drop multiple file upload with a preview in the web application. Dropzone is light-weight and does not depend on any other jQuery library. DropzoneJS does not handle the file upload functionality, it sends the files to the server via AJAX. You need to use PHP to upload files to the server.

Upload files to the server using PHP. Insert files information in the database using PHP and MySQL. Before getting started, take a look at the file structure of drag & drop file upload with PHP. To store the information of the uploaded file a table is required in the database.

The database table image_info contains columns to store the auto-generated unique image id, image path where it is uploaded and the date/time when it is added. This screenshot shows the edit form with the existing image preview and a Dropzone to let the user upload the new image to replace the existing one.

. If you want another name than file you can configure dropzone with the option paramName. If you want your file uploads to work even without JavaScript, you can include an element with the class fallback that dropzone will remove if the browser is supported.

Dropzone does not handle your file uploads on the server. You have to implement the code to receive and store the file yourself. See the section Server side implementation for more information.

Defines where to display the file previews – if null the Dropzone element itself is used. Can be a plain HTMLElement or a CSS selector. The element should have the dropzone-previews class so the previews are displayed properly.
