This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
What does it do?¶
This extension provides an API for using Plupload within your own extensions. Basically I’ve implemented an eID to handle file uploads managed by simple configuration records. You are able to implement whatever is possible with Plupload by using TypoScript and template files.
The extension additionally provides a simple FE plugin to upload files with an nice jQuery UI widget which uses the best technology available on clientside.
An API example to send big files by mail is available in TER, search for EXT:mailfiles.
What is Plupload?¶
“Plupload allows you to upload files using HTML5 Silverlight, Flash or normal forms, providing some unique features such as upload progress, image resizing and chunked uploads.
The developers of TinyMCE brings you Plupload, a highly usable upload handler for your Content Management Systems or similar. Plupload is currently separated into a Core API and a jQuery upload queue widget this enables you to either use it out of the box or write your own custom implementation .”
