Kalender PHP dengan acara berulang dari database MySQL

Jika ada yang ingin melakukan hal serupa, saya akan memposting kode yang saya tulis dan uji dalam lima jam terakhir.

Saya memutuskan untuk mengubah dua tabel saya menjadi tiga, memindahkan semua opsi berulang ke tabel ketiga:

'churchcal_events' - ada kolom tambahan untuk info acara yang belum saya sertakan di sini

+----+-----------+------------+------------+------------+-----------+
| id | name      | date       | starttime  | endtime    | recurring |
+----+-----------+------------+------------+------------+-----------+
| 1  | Event 1   | 2013-04-01 | 10:30:00   | 12:00:00   | 0         |
| 2  | Event 2   |            | 14:00:00   | 15:00:00   | 1         |
| 3  | Event 3   |            | 09:00:00   |            | 1         |
| 4  | Event 4   |            | 19:00:00   | 21:00:00   | 1         |
+----+-----------+------------+------------+------------+-----------+

'churchcal_assign' - merutekan acara ke kalender yang sesuai (karena akan ada kalender untuk berbagai departemen di seluruh situs web)

+----------+-------------+
| event_id | calendar_id | 
+----------+-------------+
| 1        | 1           |
| 2        | 1           |
| 3        | 1           |
| 4        | 1           |
+----------+-------------+

'churchcal_recur_events' - Berikut adalah aturan untuk pengulangan setiap acara

+----------+-----------+------------+----------------+------------+-------------+-----------+
| event_id | frequency | recur_type | recur_day_num  | recur_day  | recur_start | recur_end |
+----------+-----------+------------+----------------+------------+-------------+-----------+
| 2        | 1         | Week       | NULL           | Sunday     | NULL        | NULL      |
| 3        | 2         | Week       | NULL           | Wednesday  | 2013-04-01  | NULL      |
| 4        | 2         | Month      | third          | Friday     | 2013-04-01  | NULL      |
+----------+-----------+------------+----------------+------------+-------------+-----------+

Kode Baru (PHP) - Ini dalam satu hari perulangan

Jika Anda tidak membuat ini dalam modul Drupal seperti saya, Anda dapat mengganti 'db_query()' dengan fungsi kueri database Anda sendiri seperti 'mysql_query()' default PHP;
