31:
32: loncourserespicker - Utilities to choose folders and resources in a course.
33:
34: =head1 SYNOPSIS
35:
36: loncourserespicker provides an interface for selecting which folders and/or
37: resources are to be either:
38:
39: (a) exported to an IMS Content Package
1.17 ! raeburn 40: (b) subject to access blocking for the duration of an exam/quiz.
1.7 raeburn 41: (c) dumped to an Authoring Space
1.15 raeburn 42: (d) receive shortened URLs to be used when deep-linking into a course
1.1 raeburn 43:
44: =head1 DESCRIPTION
45:
46: This module provides routines to generate a hierarchical display of folders
47: and resources in a course which can be selected for specific actions.
48:
49: The choice of items is copied back to the main window from which the pop-up
50: window used to display the Course Contents was opened.
51:
52: =head1 OVERVIEW
53:
54: The main subroutine: &create_picker() will display the hierarchy of folders,
1.6 raeburn 55: sub-folders, and resources in the Main Content area. Items can be selected
56: using checkboxes, and/or a "Check All" button. Selection of a folder
1.1 raeburn 57: causes the contents of the folder to also be selected automatically. The
58: propagation of check status is recursive into sub-folders. Likewise, if an
59: item deep in a nested set of folders and sub-folders is unchecked, the
60: uncheck will propagate up through the hierarchy causing any folders at
61: a higher level to become unchecked.
62:
63: There is a submit button, which will be named differently according to the
1.7 raeburn 64: context in which resource/folder selection is being made.
1.1 raeburn 65:
1.17 ! raeburn 66: The four contexts currently supported are: IMS export, selection of
1.1 raeburn 67: content to be subject to access restructions for the duration of an
1.17 ! raeburn 68: exam, selection of items for dumping to an Authoring Space, and
! 69: display or creation of shortened URLs for deep-linking,
1.1 raeburn 70:
71: =head1 INTERNAL SUBROUTINES
72:
73: =item &create_picker()
74:
75: Created HTML mark up to display contents of course with checkboxes to
76: select items. Checking a folder causes recursive checking of items
77: within the folder. Unchecking a resource causing unchecking of folders
78: containing the item back up to the top level.
79:
1.14 raeburn 80: Inputs: 11.
1.1 raeburn 81: - $navmap -- Reference to LON-CAPA navmap object
82: (encapsulates information about resources in the course).
83:
84: - $context -- Context in which course resource selection is being made.
1.15 raeburn 85: Currently imsexport, examblock, dumpdocs, and shorturls
86: are supported.
1.1 raeburn 87:
88: - $formname -- Name of the form in the window from which the pop-up
89: used to select course items was launched.
90:
91: - $crstype -- Course or Community
92:
93: - $blockedmaps -- Reference to hash of previously selected maps
94: (e.g., for a live exam block).
95:
96: - $blockedresources -- Reference to hash of resources selected
97: previously (e.g., for an exam block).
98:
99: - $block -- An internal ID (integer) used to track which exam
100: block currently being configured.
101:
1.7 raeburn 102: - $preamble -- HTML form elements used to select Authoring Space
103: if more than one available, and also set name of 'Folder
104: in Authoring Space' where content will be dumped, when
105: context is 'dumpdocs'.
106:
107: - $numhome -- number of possible Authoring Spaces where content could
108: be dumped when context is 'dumpdocs'.
109:
110: - $uploadedfiles -- Reference to hash: keys are paths to files in
111: /home/httpd/lonUsers/$cdom/$1/$2/$3/$cnum/userfiles.
1.15 raeburn 112:
113: - $tiny -- Reference to hash: keys are symbs of course items for which
114: shortened URLs have already been created.
115:
1.14 raeburn 116: - $readonly -- if true, no "check all" or "uncheck all" buttons will
117: be displayed, and checkboxes will be disabled, if this
1.15 raeburn 118: is for an exam block or for shortened URL creation.
1.7 raeburn 119:
1.1 raeburn 120:
121: Output: $output is the HTML mark-up for display/selection of content
122: items in the pop-up window.
123:
124: =item &respicker_javascript()
125:
126: Creates javascript functions for checking/unchecking all items, and
127: for recursive checking triggered by checking a folder, or recursive
128: (upeards) unchecking of an item within a folder.
129:
130: Inputs: 7.
131: - $startcount -- Starting offset of form element numbering for items
132:
133: - $numcount -- Total numer of folders and resources in course.
134:
135: - $context -- Context in which resources are being displayed
1.17 ! raeburn 136: (imsexport, examblock, dumpdocs or shorturls).

1.7 raeburn 158:
159:
160: =item &clean()
161:
162: Takes incoming title and replaces non-alphanumeric characters with underscore,
163: so title can be used as suggested file name (with appended extension) for file
1.11 bisitz 164: copied from course to Authoring Space.
1.7 raeburn 165:
166:
167: =item &enumerate_course_contents()

171: map url, or symb, for an iteration through the course, as seen by
172: a Course Coordinator. Used to generate numerical IDs to facilitate
173: (a) storage of lists of maps or resources to be blocked during an exam,
