# Utility function used when rendering the <student> tag. |
|
# This function renders a segment of course personel |
|
# Personel are broken up by the helper into past, current and |
|
# future...each one gets is own subpage of selection. |
|
# This sub renders one of these pages. |
|
# Parameters: |
|
# $sections - Set of sections in the course (hash reference). |
|
# $students - Students in the section. (ref to array of references |
|
# to arrays). |
|
# $formprefix - form path prefix for form element names |
|
# This is used to make each form element |
|
# so that the segments having to do with each |
|
# set of students won't collide. |
|
# $defaultusers - reference to a hash containng |
|
# the set of users that should be on or off. |
|
# $multiselect - True if multiselect allowed. |
|
# $resultname - Name of result variable. |
|
# $javascript - If true, the javascript to run this is output |
|
# This should be true for the first call for a page |
|
# and false for all other calls... only matters if |
|
# multiselect is true. |
|
# Returns: |
|
# HTML text to add to the rendering of the helper. |
