Later, when we drop a file, our jQuery code will display a preview by adding the following markup to the page: The message span is updated if there is an error condition (for example if your browser does not support one of the HTML5 APIs that this example relies on). We will pass this element to the plugin, which will detect when a file is dropped on top of it. The only div that the Filedrop interacts with, is #dropbox. HTML5 File Drag and Drop Upload with jQuery and PHP | Tutorialzine Demoĭrop images here to upload. We have a regular HTML5 document, which includes our stylesheet and script.js file, the Filedrop plugin and the jQuery library. The markup of our Upload Center couldn't be simpler. A simple fallback solution for older browsers would be to display a regular file input dialog, but we won't be doing this today, as we will be focusing our attention on using HTML5. One of them is Filedrop, which is a wrapper around this functionality, and provides features for limiting maximum file size and specifying callback functions, which is really handy for integrating it into your web applications.Ĭurrently file uploads work only in Firefox and Chrome, but upcoming major versions of the other browsers also include support for it. Fortunately, there are jQuery plugins that can do this for us.
Sounds complicated? Yes, it could use some optimization.
Uploading files using HTML5 is actually a combination of three technologies - the new File Reader API, the also new Drag & Drop API, and the good ol' AJAX (with the addition of binary data transfer). Currently, the photos are only stored in a folder on the server, but you could improve it any way you like. The photos will have a preview and a progress bar, all of which controlled on the client side. Today we will be developing a small web application called Upload Center, that will allow people to upload photos from their computers by dragging and dropping them onto the browser window, possible with the new HTML5 APIs exposed by modern browsers.
