, 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'); require_once '../inc/global.inc.php'; // Including necessary files require_once 'work.lib.php'; require_once api_get_path(LIBRARY_PATH).'document.lib.php'; require_once api_get_path(LIBRARY_PATH).'groupmanager.lib.php'; require_once api_get_path(LIBRARY_PATH).'mail.lib.inc.php'; require_once api_get_path(LIBRARY_PATH).'fckeditor/fckeditor.php'; include_once api_get_path(LIBRARY_PATH).'fileManage.lib.php'; require_once api_get_path(LIBRARY_PATH).'fileUpload.lib.php'; require_once api_get_path(LIBRARY_PATH).'fileDisplay.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 = ''; $is_special = false; if (!empty($my_folder_data)) { if ($my_folder_data['filetype'] == 'folder') { $curdirpath = $my_folder_data['url']; if (!empty($my_folder_data['has_properties'])) { $is_special = true; } } } $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); $iprop_table = Database :: get_course_table(TABLE_ITEM_PROPERTY); $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'] .
