カレンダー機能がありますが、問題は、10、11、および 12 か月のイベントのみが表示され、それより前に表示されないことです。
したがって、URLに次を追加した場合：
calender.php?month=01&year=2013 TO calender.php?month=09&year=2013, No events will be displayed.
しかし、もしそうなら：
calender.php?month=10&year=2013, calender.php?month=11&year=2013 or calender.php?month=12&year=2013, these will display fine.
このバグの原因となっているコードの部分が見つかりません。アイデアはありますか? :o/
完全な機能コードは次のとおりです。
