- &viewable_section() checks if display of roles in a course should be restricted to a single section, because viewer's role is sectioned.
- in &modifystudent() include courseID in args sent to lonnet::modifystudent() to permit use in domain context.
- &print_upload_manager_header() takes additional 6th arg - $permission
- retrieve groupslist used in javascript for section name checking from &get_groupslist().
- &javascript_validations() takes three additional args: $context, $permission and $groupslist.
- replace mode type of 'auth' in javascript_validations() with 'upload'.
- additional mode added - "singlestudent" for javascript for validation of a single section when enrolling a single student.
- depending on mode, javascript function verify_message(), includes different content from $setsection_call and &setsections_javascript.
- in domain mode, uses setCourse() to set form element names for addition of roles to a course
- in singlestudent mode, checks student's proposed section is valid.
- in upload mode, checks validity of proposed default section for uses in uploaded file.
- if users has section-specific 'cst' priv, enrollment is in this section.
- &print_upload_manager_footer() takes 8th arg - permission.
- &print_upload_manager_header() takes 6th arg = permission.
- &setup_date_selectors() takes 5th arg - $formname.
- &date_setting_table() used to create table for starting and ending access dates takes two additional args - $formname, $permission.
- option to make dates default added in case where access dates set for a file upload in course context.
- change names of course, domain and description for course/role/section selection box in file upload in domain context. Names now consistent with single user create/modify interface so setCourse() works both places.
- "sections" form element added for storage of aggregated section selections.
- custom role identifier in default role selector modified so custom roles for uploaded users now named correctly.
- gather all roles in a course for an uploaded user, so check if user info fields are modifiable is comprehensive.
- in filtered display of users in a course, use &viewable_section() to inhibit display of section-specific roles from other sections to a viewer with section-specific priv.
- eliminate creation of empty array - @{$userlist->{$item}} = () when building display list - was causing empty ros in data table.
