, Ghent University - ability for course admins to specify wether uploaded documents are visible or invisible by default. * @author Roan Embrechts, code refactoring and virtual course support * @author Frederic Vauthier, directories management * @author Julio Montoya BeezNest 2011 LOTS of bug fixes * * @todo refactor more code into functions, use quickforms, coding standards, ... jm */ /** * STUDENT PUBLICATIONS MODULE * * Note: for a more advanced module, see the dropbox tool. * This one is easier with less options. * This tool is better used for publishing things, * sending in assignments is better in the dropbox. * * GOALS * ***** * Allow student to quickly send documents immediately visible on the Course * * The script does 5 things: * * 1. Upload documents * 2. Give them a name * 3. Modify data about documents * 4. Delete link to documents and simultaneously remove them * 5. Show documents list to students and visitors * * On the long run, the idea is to allow sending realvideo . Which means only * establish a correspondence between RealServer Content Path and the user's * documents path. * * */ /* INIT SECTION */ $language_file = array('exercice', 'work', 'document', 'admin', 'gradebook'); require_once '../inc/global.inc.php'; $current_course_tool = TOOL_STUDENTPUBLICATION; /* Configuration settings */ api_protect_course_script(true); // Including necessary files require_once 'work.lib.php'; $course_id = api_get_course_int_id(); $course_info = api_get_course_info(); $user_id = api_get_user_id(); $id_session = api_get_session_id(); // Section (for the tabs) $this_section = SECTION_COURSES; $work_id = isset($_GET['id']) ? intval($_GET['id']) : null; $my_folder_data = get_work_data_by_id($work_id); $curdirpath = ''; $htmlHeadXtra[] = api_get_jqgrid_js(); $htmlHeadXtra[] = to_javascript_work(); $htmlHeadXtra[] = ''; // Table definitions $main_course_table = Database :: get_main_table(TABLE_MAIN_COURSE); $work_table = Database :: get_course_table(TABLE_STUDENT_PUBLICATION); $TSTDPUBASG = Database :: get_course_table(TABLE_STUDENT_PUBLICATION_ASSIGNMENT); $table_course_user = Database :: get_main_table(TABLE_MAIN_COURSE_USER); $table_user = Database :: get_main_table(TABLE_MAIN_USER); $table_session = Database :: get_main_table(TABLE_MAIN_SESSION); $table_session_course_user = Database :: get_main_table(TABLE_MAIN_SESSION_COURSE_USER); /* Constants and variables */ $tool_name = get_lang('StudentPublications'); $course_code = api_get_course_id(); $session_id = api_get_session_id(); $is_course_member = CourseManager::is_user_subscribed_in_real_or_linked_course($user_id, $course_code, $session_id); $is_course_member = $is_course_member || api_is_platform_admin(); $currentCourseRepositorySys = api_get_path(SYS_COURSE_PATH).$_course['path'].'/'; $currentCourseRepositoryWeb = api_get_path(WEB_COURSE_PATH).$_course['path'].'/'; $currentUserFirstName = $_user['firstName']; $currentUserLastName = $_user['lastName']; $currentUserEmail = $_user['mail']; $item_id = isset($_REQUEST['item_id']) ? intval($_REQUEST['item_id']) : null; $parent_id = isset($_REQUEST['parent_id']) ?
