|
|
* SCRIPT PURPOSE
|
|
*
|
|
* This script initializes and manages Chamilo session information. It
|
|
* keeps available session information up to date.
|
|
*
|
|
* You can request a course id. It will check if the course Id requested is the
|
|
* same as the current one. If it isn't it will update session information from
|
|
* the database. You can also force the course reset if you want ($cidReset).
|
|
*
|
|
* All the course information is stored in the $_course array.
|
|
*
|
|
* You can request a group id. The script will check if the group id requested is the
|
|
* same as the current one. If it isn't it will update session information from
|
|
* the database. You can also force the course reset if you want ($gidReset).
|
|
*
|
|
* The course id is stored in $_cid session variable.
|
|
* The group id is stored in $_gid session variable.
|
|
*
|
|
*
|
|
* VARIABLES AFFECTING THE SCRIPT BEHAVIOR
|
|
*
|
|
* string $login
|
|
* string $password
|
|
* boolean $logout
|
|
*
|
|
* string $cidReq : course id requested
|
|
* boolean $cidReset : ask for a course Reset, if no $cidReq is provided in the
|
|
* same time, all course informations is removed from the
|
|
* current session
|
|
*
|
|
* int $gidReq : group Id requested
|
|
* boolean $gidReset : ask for a group Reset, if no $gidReq is provided in the
|
|
* same time, all group informations is removed from the
|
|
* current session
|
|
*
|
|
*
|
|
* VARIABLES SET AND RETURNED BY THE SCRIPT
|
|
*
|
|
* All the variables below are set and returned by this script.
|
|
*
|
|
* USER VARIABLES
|
|
*
|
|
* string $_user ['firstName' ]
|
|
* string $_user ['lastName' ]
|
|
* string $_user ['mail' ]
|
|
* string $_user ['lastLogin' ]
|
|
* string $_user ['official_code']
|
|
* string $_user ['picture_uri' ]
|
|
* string $_user['user_id']
|
|
*
|
|
* boolean $is_platformAdmin
|
|
* boolean $is_allowedCreateCourse
|
|
*
|
|
* COURSE VARIABLES
|
|
* see the function get_course_info_with_category
|
|
* boolean $is_courseMember
|
|
* boolean $is_courseTutor
|
|
* boolean $is_courseAdmin
|
|
*
|
|
*
|
|
* GROUP VARIABLES
|
|
*
|
|
* int $_gid (the group id)
|
|
*
|
|
*
|
|
* IMPORTANT ADVICE FOR DEVELOPERS
|
|
*
|
|
* We strongly encourage developers to use a connection layer at the top of
|
|
* their scripts rather than use these variables, as they are, inside the core
|
|
* of their scripts. It will make code maintenance much easier.
|
|
*
|
|
* Many if the functions you need you can already find in the
|
|
* main_api.lib.php
|
|
*
|
|
* We encourage you to use functions to access these global "kernel" variables.
|
|
* You can add them to e.g. the main API library.
|
|
*
|
|
*
|
|
* SCRIPT STRUCTURE
|
|
*
|
|
* 1. The script determines if there is an authentication attempt. This part
|
|
* only chek if the login name and password are valid. Afterwards, it set the
|
|
* $_user['user_id'] (user id) and the $uidReset flag. Other user informations are retrieved
|
|
* later. It's also in this section that optional external authentication
|
|
* devices step in.
|
|
*
|
|
* 2. The script determines what other session informations have to be set or
|
|
* reset, setting correctly $cidReset (for course) and $gidReset (for group).
|
|
*
|
|
* 3. If needed, the script retrieves the other user informations (first name,
|
|
* last name, ...) and stores them in session.
|
|
*
|
|
* 4. If needed, the script retrieves the course information and stores them
|
|
* in session
|
|
*
|
|
* 5. The script initializes the user permission status and permission for the
|
|
* course level
|
|
*
|
|
* 6. If needed, the script retrieves group informations an store them in
|
|
* session.
|
|
*
|
|
* 7. The script initializes the user status and permission for the group level.
