5.x _CourseList.php	_CourseList::exclude_all_subjects_except($subject, $bool_reassign_valid_name = true)

Go through the courseList and take out any course which does not have the $subject as its subject_id.

Parameters

string $subject:

bool $bool_reassign_valid_name:

• If set to TRUE, we will look at other possible valid names for this course. If we find one, we will reassign the course's subject_id and course_num to the new valid name.
