Attach Files to a Ticket - Design Story

the design story for attaching files to a ticket.

The basic idea:

create attachment row to allow user
1. slelect files from local desktop
2. upload files to server, save as MediaWiki File.
3. append file url to description or comment textarea.
add attachment row on ticket details form
add new attachment row on comment form

Mediawiki special page to handle PLupload AJAX request.
PHP function to render HTML for file selection and upload section (row). It will be used on both ticket details form and comment form.
PHP function to generate JavaScript client to build and initialize the plupload.uploader object.
1. set up plupload.Uploader object: browse_button, container, multi_selection, etc.
2. Filter for file selection: images, zip, pdf, etc.
3. Be able to set up metadata for MediaWiki File: file description, file category, comment, file name prefix, etc. (multipart_param option and BeforeUpload event)
4. Be able to switch cursor between normal and wait.
5. Error handling. (Error event from plupload).
PHP function to generate JavaScript code to handle AJAX response from MediaWiki Special page. Bascially how to handle (display) the URLs for those uploaded files.
Admin page to allow user to customize the attachment's metadata, category, file name, etc.

tags: tags will attache to each attachment attached to a ticket. It could be the Categories if we save the file as a MediaWiki_ File.
