, Ghent University @author: Toon Van Hoecke , Ghent University @author: Eric Remy (initial version) @version: 2.2 alpha @description: this file generates a general agenda of all items of the courses the user is registered for ============================================================================== version info: ------------- -> version 2.2 : Patrick Cool, patrick.cool@ugent.be, november 2004 Personal Agenda added. The user can add personal agenda items. The items are stored in a dokeos_user database because it is not course or platform based. A personal agenda view was also added. This lists all the personal agenda items of that user. -> version 2.1 : Patrick Cool, patrick.cool@ugent.be, , oktober 2004 This is the version that works with the Group based Agenda tool. -> version 2.0 (alpha): Patrick Cool, patrick.cool@ugent.be, , oktober 2004 The 2.0 version introduces besides the month view also a week- and day view. In the 2.5 (final) version it will be possible for the student to add his/her own agenda items. The platform administrator can however decide if the students are allowed to do this or not. The alpha version only contains the three views. The personal agenda feature is not yet completely finished. There are however already some parts of the code for adding a personal agenda item present. this code was not released in an official dokeos but was only used in the offical server of the Ghent University where it underwent serious testing -> version 1.5: Toon Van Hoecke, toon.vanhoecke@ugent.be, december 2003 -> version 1.0: Eric Remy, eremy@rmwc.edu, 6 Oct 2003 The tool was initially called master-calendar as it collects all the calendar items of all the courses one is subscribed to. It was very soon integrated in Dokeos as this was a really basic and very usefull tool. /* ============================================================================== HEADER ============================================================================== */ // loading the language file $langFile = 'agenda'; // we are not inside a course, so we reset the course id $cidReset = true; // setting the global file that gets the general configuration, the databases, the languages, ... require ('../inc/global.inc.php'); $this_section = SECTION_MYAGENDA; require (api_get_path(LIBRARY_PATH).'groupmanager.lib.php'); // setting the name of the tool $nameTools = get_lang('MyAgenda'); // if we come from inside a course and click on the 'My Agenda' link we show a link back to the course // in the breadcrumbs if (!empty ($_GET['coursePath'])) { $interbreadcrumb[] = array ('url' => api_get_path(WEB_COURSE_PATH).$_GET['coursePath'].'/index.php', 'name' => $_GET['courseCode']); } // this loads the javascript that is needed for the date popup selection $htmlHeadXtra[] = ""; // showing the header Display::display_header(get_lang('MyAgenda')); /* ============================================================================== SETTING SOME VARIABLES ============================================================================== */ // setting the database variables $TABLECOURS = Database :: get_main_table(MAIN_COURSE_TABLE); $TABLECOURSUSER = Database :: get_main_table(MAIN_COURSE_USER_TABLE); $TABLEAGENDA = Database :: get_course_table(AGENDA_TABLE); $TABLE_ITEMPROPERTY = Database :: get_course_table(LAST_TOOL_EDIT_TABLE); $TABLE_PERSONAL_AGENDA = Database :: get_user_personal_table(PERSONAL_AGENDA); // the variables for the days and the months // Defining the shorts for the days $DaysShort = array (get_lang("SundayShort"), get_lang("MondayShort"), get_lang("TuesdayShort"), get_lang("WednesdayShort"), get_lang("ThursdayShort"), get_lang("FridayShort"), get_lang("SaturdayShort")); // Defining the days of the week to allow translation of the days $DaysLong = array (get_lang("SundayLong"), get_lang("MondayLong"), get_lang("TuesdayLong"), get_lang("WednesdayLong"), get_lang("ThursdayLong"), get_lang("FridayLong"), get_lang("SaturdayLong")); // Defining the months of the year to allow translation of the months $MonthsLong = array (get_lang("JanuaryLong"), get_lang("FebruaryLong"), get_lang("MarchLong"), get_lang("AprilLong"), get_lang("MayLong"), get_lang("JuneLong"), get_lang("JulyLong"), get_lang("AugustLong"), get_lang("SeptemberLong"), get_lang("OctoberLong"), get_lang("NovemberLong"), get_lang("DecemberLong")); /* ============================================================================== SANITY CHECK ============================================================================== */ // You can delete this if you have manually added the new database and tables // this piece of code was added to avoid having to explain to non sys-admin // what has to be done in order to get this tool working if (get_setting("allow_personal_agenda") == "true") { // I use a separate database for storing all the information of user driven tools // as the Personal Agenda tool has the potential to create a large database. // If you do not want a separate database for the personal agenda tool you can add the table to // the main dokeos database by changing $DATABASE_USER_TOOLS above to $mainDbName $sql_create_database = "CREATE DATABASE IF NOT EXISTS `$DATABASE_USER_TOOLS`"; $result = api_sql_query($sql_create_database); $sql_create_table = "CREATE TABLE IF NOT EXISTS $TABLE_PERSONAL_AGENDA ( `id` int(11) NOT NULL auto_increment, `user` int(11), `title` text, `text` text, `date` datetime default NULL, `course` varchar(255), UNIQUE KEY `id` (`id`)) TYPE=MyISAM AUTO_INCREMENT=1"; $result = api_sql_query($sql_create_table); } /*============================================================================== TREATING THE URL PARAMETERS 1.
