During the Guru work to support Joomla 4, you should support triggering events for Student/Teacher activity so plug-in can be created to act on them.
This will benefit both Guru users and Joomlart as they will be able to benefit from other Joomla 3rd-party developers who can add-value by supporting Guru in their components.
Currently, Guru does not support triggers for events, relying on single page requests made to com_guru to execute SQL codes to check for student purchases, certificates, course completions, quiz & exam activity slams performance.
Create Joomla triggers for these events: student purchases, certificates, course completions, quiz & exam activity slams performance.
Thank you for your consideration my friends!
