Since	1.0
Version	$Id$
Source Code	framework/web/widgets/CMultiFileUpload.php

CMultiFileUpload generates a file input that can allow uploading multiple files at a time.

This is based on the jQuery Multi File Upload plugin. The uploaded file information can be accessed via $_FILES[widget-name], which gives an array of the uploaded files. Note, you have to set the enclosing form's 'enctype' attribute to be 'multipart/form-data'.
