Branches:
MAIN
CVS tags:
HEAD
Highlights:
Now have 'modify student data' options, although you cannot actually modify
any student data yet.
Selecting a students name in the classlist display will take you to their
'aboutme' page.
Gory details:
Many internal changes to state keeping.
The current page displayed is determined by two parameters, 'action' and
'state'.
Changed subroutine names to describe what they do.
Reformatted single student enrollment form.
Added input variable to &show_class_list to determine what sort of link
to place around user names.
Modified &print_html_classlist to take advantage of new &show_class_list
Added &print_modify_student_form, which works wonderfully.
Added &modify_single_student, which tells you what it wants to do but
cannot actually do it.
Added &get_enrollment_data, which will probably be removed soon.
Added &drop_students to do just that.
Modified &handler to implement state keeping changes and document it.
