|
* STUDENT PUBLICATIONS MODULE
|
|
*
|
|
* Note: for a more advanced module, see the dropbox tool.
|
|
* This one is easier with less options.
|
|
* This tool is better used for publishing things,
|
|
* sending in assignments is better in the dropbox.
|
|
*
|
|
* GOALS
|
|
* *****
|
|
* Allow student to quickly send documents immediately
|
|
* visible on the course website.
|
|
*
|
|
* The script does 5 things:
|
|
*
|
|
* 1. Upload documents
|
|
* 2. Give them a name
|
|
* 3. Modify data about documents
|
|
* 4. Delete link to documents and simultaneously remove them
|
|
* 5. Show documents list to students and visitors
|
|
*
|
|
* On the long run, the idea is to allow sending realvideo . Which means only
|
|
* establish a correspondence between RealServer Content Path and the user's
|
|
* documents path.
|
|
*
|
|
* All documents are sent to the address /$_configuration['root_sys']/$currentCourseID/document/
|
|
* where $currentCourseID is the web directory for the course and $_configuration['root_sys']
|
|
* usually /var/www/html
|
|
*
|
|
* Modified by Patrick Cool, february 2004:
|
|
* Allow course managers to specify wether newly uploaded documents should
|
|
* be visible or unvisible by default
|
|
* This is ideal for reviewing the uploaded documents before the document
|
|
* is available for everyone.
|
|
*
|
|
* note: maybe the form to change the behaviour should go into the course
|
|
* properties page?
|
|
* note 2: maybe a new field should be created in the course table for
|
|
* this behaviour.
|
|
*
|
|
* We now use the show_score field since this is not used.
|
|
*
