This is an old revision of the document!

Table of Contents

:!: this isn't yet a plugin, but a quick, unstable hack.

Once installed, under the edit box appears a list of media files attached to this page.

INVOLVED FILES

new files

  • tpl/*/media_attached.php
  • lib/exe/media_attached.php

editied files

  • inc/html.php
  • inc/template.php
  • tpl/*/layout.css
  • lib/scripts/script.js

PROBLEMS

  • the java script that inserts the media code automatically in the edit field whenever you click on an image name isn't working
