Member Function Documentation

activity_completed_by()

core_analytics\local\indicator\community_of_inquiry_activity::activity_completed_by ( \cm_info $activity, $starttime, $endtime, $student = false )

protectedinherited

protectedinherited

True if the activity is due or it has been closed during this period, false if during another period, null if no due time.

It can be overwritten by activities that allow teachers to set a due date or a time close separately from Moodle availability system. Note that in most of the cases overwriting get_timeclose_field should be enough.

Returns true or false if the time close date falls into the provided time range. Null otherwise.
