AppBundle/Controller/DefaultController. (You may wanna check out the Official Docs for an in-depth file-upload handling logic) So lets write the logic to handle the file that will be sent to this URL. Var dropzone_default = new Dropzone(".dropzone", ' as the path. We set it to the path that will handle the uploaded file. We initialize dropzone with certain parameters (I won’t get much into its details, it being out of the scope of this tutorial) The most important configuration option is the url parameter. Some of Dropzone's highlights are: Next - Getting Started. It is one of the most popular drag and drop library on the web and is used by millions of people. Let’s say I have a template as followsĭropzone attaches itself to any element having class ‘dropzone’, hence it is imperative that we set toDiscover = false which will disable dropzone’s default behaviour. Dropzone is a simple JavaScript library that helps you add file drag and drop functionality to your web forms. Start by including the dependencies, dropzone.js and dropzone.css files in your twig template. So how can we use this library with a Symfony app? Lets see how…
An alternate is to use the simplicity of JS File Upload with Dropzone and Symfony 3.x+ that’ll not only help fast-track development but also avoid one from rewriting the wheel.ĭropzone, IMHO, is one of the top libraries out there to handle file uploads that allows file previews(thumbnails), transferring files in chunks, viewing upload progress and a ton of other features. Besides, the documentation is pretty convoluted in itself.
It requires a lot of tweaking for stuff as simple as displaying the upload progress or even generate thumbnails for images, etc. Handling File Uploads completely server-side (especially with Symfony) doesn’t usually seem a pretty straightforward task.
