|
|
* Updates the Dokeos files from an older version
|
|
* IMPORTANT: This script has to be included by install/index.php and update_courses.php
|
|
*
|
|
* SYSTEM_INSTALLATION is defined in the install/index.php
|
|
* DOKEOS_COURSE_UPDATE is defined in update_courses.php
|
|
*
|
|
* When SYSTEM_INSTALLATION or DOKEOS_COURSE_UPDATE is defined, do for every course:
|
|
* - remove the .htaccess in the document folder
|
|
* - remove the index.php in the group folder
|
|
* - write a new group/index.php file, make it an empty html file
|
|
* - remove the index.php of the course folder
|
|
* - write a new index.php file in the course folder, with some settings
|
|
* - create a 'temp' directory in the course folder
|
|
* - move the course folder inside the courses folder of the new Dokeos installation
|
|
* - move the group documents from the group folder to the document folder,
|
|
* keeping subfolders intact
|
|
* - stores all documents inside the database (document and item_property tables)
|
|
* - remove the visibility field from the document table
|
|
* - update the item properties of the group documents
|
|
*
|
|
* Additionally, when SYSTEM_INSTALLATION is defined
|
|
* - write a config file, configuration.php, with important settings
|
|
* - write a .htaccess file (with instructions for Apache) in the courses directory
|
|
* - remove the new main/upload/users directory and rename the main/img/users
|
|
* directory of the old version to main/upload/users
|
|
* - rename the old configuration.php to configuration.php.old,
|
|
* or if this fails delete the old configuration.php
|
|
*
|
|
* @package chamilo.install
