APIs

API layers: https://docs.moodle.org/dev/External_services_security

• External server interface (SOAP, REST, RSS, etc.)
• Public PHP api (need to verify all parameters and access control, ...)
• Low level internal api (fast, basic param validation, no access control, strict rules)

Web services api (SOAP): https://docs.moodle.org/dev/Web_services_API

• https://docs.moodle.org/dev/External_functions_API
• Helper Plugin bauen und notwendige Daten darüber per Service zur Verfügung stellen
• Basic example: Gruppe in Moodle-Kurs erstellen: https://docs.moodle.org/dev/Adding_a_web_service_to_a_plugin

Privilegien

https://docs.moodle.org/dev/Access_API

When implementing access control always ask "Does the user have capability to do something?". It is incorrect to ask "Does the user have a role somewhere?".

• Roles: https://docs.moodle.org/dev/Roles
• Example capability: moodle/course:managegroups
  • e.g. create groups into moodle course
  • function has_capability($capability, context $context, $user = null, $doanything = true)

Enrolment api: https://docs.moodle.org/dev/Enrolment_API

Nutzer für Kurse:

• function is_enrolled(context $context, $user = null, $withcapability = '', $onlyactive = false)
• function get_enrolled_users(context $context, $withcapability = '', $groupid = 0, $userfields = 'u.*', $orderby = '', $limitfrom = 0, $limitnum = 0)

Enrolled users may fully participate in a course. Active user enrolment allows user to enter course. Only enrolled users may be group members. Grades are stored only for enrolled users.
