FancyUpload - Swiff meets Ajax (v1.0)

Project FancyUpload - Swiff meets Ajax Showcase Swiff meets Ajax for powerful and elegant uploads. FancyUpload is a file-input replacement which features an unobtrusive, multiple-file selection menu and queued upload with an animated progress bar. It is easy to setup, is server independent, completely styleable via CSS and XHTML and uses MooTools to work in all modern browsers.

Showcases:

Showcase “Queued Photo Uploader”

The known example, queued upload for photos.

The Action Happens Here

Select Files

Selected photos will be queued for upload, select all your files and start upload the upload.

Upload Queue
Check the selected files and start uploading.

Get the new FancyUpload 3.0! 3.0 is the current release (more stable, more showcases, more documentation) and it is compatible with 2.0 and 2.1 (Old versions are not maintained anymore!).

What happens?

Check the automated log file after upload. The PHP script does not save the files but logs every request.

JavaScript & MooTools

window.addEvent('load', function() {
	/**
	 * We take the first input with this class we can find ...
	 */
	var input = $('demo-filedata');
 
	/**
	 * Simple and easy
	 *
	 * swf: the path to the swf
	 * container: the object is embedded in this container (default: document.body)
	 *
	 * NOTE: container is only used for the first uploader u create, all others depend
	 * on the same swf in that container, so the container option for the other uploaders
	 * will be ignored.
	 *
	 */
	var upload = new FancyUpload(input, {
		swf:  '/project/fancyupload/1-0/source/Swiff.Uploader.swf',
		queueList: 'demo-queue'
	});
 
	/**
	 * We create the clear-queue link on-demand, since we don't know if the user has flash/javascript.
	 *
	 * You can also create the complete xhtml structure thats needed for the queue here, to be sure
	 * that its only in the document when the user has flash enabled.
	 */
	$('demo-status').adopt(new Element('a', {
		'href': '#',
		'events': {
			'click': (function(e) {
				e.stop();
				upload.clearList(false);
			}).bindWithEvent()
		}
	}).setHTML('Clear Completed'));
 
});
