Moodle in English: Develop a plugin to allow granular course visibility / access

Develop a plugin to allow granular course visibility / access

by Alex M - Friday, March 5, 2021, 6:35 PM

We want to develop a plugin to allow granular course visibility and access.

We already found

https://moodle.org/mod/forum/discuss.php?d=350518#

So with standard functionality it is already possible to allow certain roles to access hidden courses in specific categories.

But we cannot put the courses in different categories, instead we want to add a field to each course to control access (by cohort).

Adding the field is not the problem, but I am searching for clean way to hook into the access system.

Would it be a clean way to extend $USER->access in an early hook with the current course path - in case the course is allowed to be viewed?

Or are there better / easier ways?

Any input is appreciated

Thanks and Regards,

Alex

In generall I cannot find a way to properly populate $USER->access

There is

load_temp_course_role($courseContext, 10);

But if I call it in after_config it's to early and I get logged out,
If I call it in after_require_login it's too late and the course access is already blockey by

if (!$course->visible and !has_capability('moodle/course:viewhiddencourses', $coursecontext)) {
...

in \require_login

I now realized that I can open /admin/roles/permissions.php?contextid=2155 where 2155 ist dhe context of a course and set the "viewhiddencourse" capability. I am wondering if this URL is accessible via a click-path in the system some where. Because in my case I just added the known context id. Is this a hidden feature or a actual feature?
