mcal_next_recurrenceNamemcal_next_recurrence — Returns an object filled with the next date the event occurs, on or after the supplied date. Returns empty date field if event does not occur or something is invalid.ReturnsA date object containing the next recurrence of the event, or an empty object if there are no more recurrences DescriptionYou need to use mcal_next_recurrence() along with mcal_list_events() to get multiple recurrences of a single event inside a date ranage. The next parameter is an array containing three keys: year, month, and mday. These denote the date after which recurrences should be returned. Notemcal_next_recurrance() does not take an event ID parameter. This is a little bit non-intuitive. Instead, it returns the next recurrance of whatever event is in the global event structure - usually, the event you have most recently fetched with mcal_fetch_event() . Because of this, you must call mcal_next_recurrence() to get all of the recurrences of an event that you need to know about before calling mcal_fetch_event() on the next event. WarningThe weekstart parameter should not affect the results of this function. However, libmcal has been mainly tested with the assumption that the week starts on Sunday, and there is an obscure bug that can cause recurrences to be missed during the last week of December, 2000, and possibly other dates. So just use MCAL_SUNDAY as the start of the week, and go ahead and code your applications to start weeks whenever you want. ExampleExample 727. Finding all events in a month, including events that occur more than once $calendar = "{/mstore}"; $MCALconnection = mcal_open($calendar, "username", "password"); // List all events during May, 2001. $year = 2001; $month = MCAL_MAY; $daysInMonth = mcal_days_in_month($month, mcal_is_leap_year($year)); // Get the unique list of all events in the month. This list // will only have one entry for each recurring event, so we'll // need additional logic to get all recurrences of each event. $eventIDs = mcal_list_events($MCALconnection, 2001, $month, 1, 2001, $month, $daysInMonth); $startOfMonthTimestamp = mktime(0, 0, 0, $month, 1, $year); $monthData = array(); foreach ($eventIDs as $eventID) { $event = mcal_fetch_event($MCALconnection, $eventID); if ($event->recur_type != MCAL_RECUR_NONE) { // We need to make sure that we only ask for recurrences // inside the month. if (mktime(0,0,0, $event->start->month, $event->start->mday, $event->start->year) <= $startOfMonthTimestamp) { $mday = 1; } else { $monthData[$event->start->mday][$event->id] = $event->title; $mday = date('j', mktime(0,0,0, $event->start->month, $event->start->mday + 1, $event->start->year)); } $next = mcal_next_recurrence($MCALconnection, MCAL_SUNDAY, array('year' => $year, 'month' => $month, 'mday' => $mday)); // Loop through recurrences while the event: // a). Has more recurrences. // b). While we are still inside the month. while (is_object($next) && isset($next->year) && (mcal_date_compare($next->year, $next->month, $next->mday, $year, $month, $daysInMonth) <= 0)) { $monthData[$next->mday][$event->id] = $event->title; $curday = $next->mday; $curmonth = $next->month; $curyear = $next->year; $next = mcal_next_recurrence($MCALconnection, MCAL_SUNDAY, array('year' => $curyear, 'month' => $curmonth, 'mday' => $curday + 1)); } } else { // It's not a recurring event, so it must be inside the month. $monthData[$event->start->mday][$event->id] = $event->title; } } // Sort the events by day. ksort($monthData); // Print out a crude calendar showing all of the days that have // events, and each event every time it occurs. foreach ($monthData as $day => $events) { echo $day . ":<br /><ul>"; foreach ($events as $title) { echo "<li>$title</li>"; } echo "</ul>"; }
