Within the manual course completion, where a teacher etc gives approval for the completion of a course through the Course Completion block, there is no tracking through the logs to see who has passed the student and when.
As part of education is all about auditability, I feel we need a simple way to track this.
I suggest the following line be added to \course\togglecompletion.php so a line is written to the log file each time a teacher manually passes a student.
add_to_log($course->id, 'user', 'manual course completion', "/view.php?id=$user", "Marked staff as complete", $USER->id);
I presently have it at line 61, however perhaps there is a better place for it. Additionally, if there is better wording or coding, feel free to change.
