1125:
1126: =head1 NAME
1127:
1128: Apache::lonpickcourse - Search for course(s) based on user-specified criteria.
1129:
1130: =head1 SYNOPSIS
1131:
1132: Invoked by other LON-CAPA modules, when course(s) need to be selected by the user.
1133:
1134: =head1 OVERVIEW
1135:
1136: Two screens are typically displayed to the user. The first is a set of criteria which are used to constrain the search for courses.
1137:
1138: =head2 Search Criteria (Screen One)
1139:
1140: =head3 Criteria:
1141:
1142: =over 4
1143:
1144: =item *
1145: Course Activity - how recently was course last visited by anyone.
1146:
1147: =item *
1148: Course Domain - the domain of the course
1149:
1150: =item *
1.84 raeburn 1151: Type - Course or Community
1.55 raeburn 1152:
1153: =item *
1154: Course Institutional Code - the institutional identifier assigned to the course
1155:
1156: =item *
1157: Course Owner's Username - the username of the owner of the course (assigned by the Domain Coordinator and/or when the course was created).
1158:
1159: =item *
1160: Course Owner's Domain - the domain of the owner of the course
1161:
1162: =item *
1.76 bisitz 1163: Course Title - text which appears in the Course Title, as set in the Course Parameters.
1.55 raeburn 1164:
1165: =item *
1166: Course ID - the internal course number (course ID part after initial 'domain_') used by LON-CAPA (this criterion is only displayed to Domain Coordinators selecting a course in the same domain as their DC role).
1167:
1168: =back
1169:
1170: The criteria setting screen is not displayed if course picking is done by a user who does not have advanced privileges (as defined by $env{'user.adv'}).
1171:
1172: =head2 Course Display (Screen Two)
1173:
1174: A list of courses matching the search criteria is displayed. If the user is not an advanced user, screen one will have been skipped and the courses displayed will be all courses in which the user has currently active roles. The information displayed for each course is:
1175:
1176: =over 4
1177:
1178: =item *
1179: Course description
1180:
1181: =item *
1182: Domain description of course domain
1183:
1184: =item *
1185: Course institutional code
1186:
1187: =item *
1188: Course owner (username:domain)
1189:
1190: =back
1191:
1192: Depending on context, the display may include a single select box for each course, allowing selection of only a single course, or may include checkboxes allowing selection of more than one course.
1193:
1194: Following selection, and/or submission, the course description, number and domain are transferred to the browser window from which the course picker window was opened. In most cases, the child window containing the course picker screens will be closed. However, in some cases closure will be delayed until a third screen has been displayed (e.g., setting of course-based conditional access controls for portfolio files). In this case the page is generated via /adm/portfolio and the page features select boxes to allow the user to select roles, access types, sections and groups.
