/**
|
|
* Main script for the documents tool
|
|
*
|
|
* This script allows the user to manage files and directories on a remote http server.
|
|
*
|
|
* The user can : - navigate through files and directories.
|
|
* - upload a file
|
|
* - delete, copy a file or a directory
|
|
* - edit properties & content (name, comments, html content)
|
|
*
|
|
* The script is organised in four sections.
|
|
*
|
|
* 1) Execute the command called by the user
|
|
* Note: somme commands of this section are organised in two steps.
|
|
* The script always begins with the second step,
|
|
* so it allows to return more easily to the first step.
|
|
*
|
|
* Note (March 2004) some editing functions (renaming, commenting)
|
|
* are moved to a separate page, edit_document.php. This is also
|
|
* where xml and other stuff should be added.
|
|
*
|
|
* 2) Define the directory to display
|
|
*
|
|
* 3) Read files and directories from the directory defined in part 2
|
|
* 4) Display all of that on an HTML page
|
|
*
|
|
* @todo eliminate code duplication between
|
|
* document/document.php, scormdocument.php
|
|
*
|
|
* @package chamilo.document
