अगर कोई भी ऐसा कुछ करना चाहता है, तो मैं पिछले पांच घंटों के भीतर वह कोड पोस्ट करूंगा जो मैंने लिखा और परीक्षण किया।
मैंने अपनी दो तालिकाओं को तीन में बदलने का फैसला किया, सभी आवर्ती विकल्पों को तीसरी तालिका में स्थानांतरित कर दिया:
'चर्चकाल_घटनाएं' - ईवेंट जानकारी के लिए अतिरिक्त फ़ील्ड हैं जिन्हें मैंने यहां शामिल नहीं किया है
+----+-----------+------------+------------+------------+-----------+
| 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 |
+----+-----------+------------+------------+------------+-----------+
'चर्चकाल_असाइन' - घटनाओं को उपयुक्त कैलेंडर में रूट करता है (क्योंकि वेबसाइट पर विभिन्न विभागों के लिए कैलेंडर होंगे)
+----------+-------------+
| event_id | calendar_id |
+----------+-------------+
| 1 | 1 |
| 2 | 1 |
| 3 | 1 |
| 4 | 1 |
+----------+-------------+
'churchcal_recur_events' - यहां हर घटना की पुनरावृत्ति के नियम दिए गए हैं
+----------+-----------+------------+----------------+------------+-------------+-----------+
| 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 |
+----------+-----------+------------+----------------+------------+-------------+-----------+
नया कोड (PHP) - यह एक दिन के लूप में है

यदि आप इसे मेरे जैसे Drupal मॉड्यूल में नहीं बना रहे हैं, तो आप 'db_query ()' को अपने स्वयं के डेटाबेस क्वेरी फ़ंक्शन जैसे PHP के डिफ़ॉल्ट 'mysql_query ()';
से बदल सकते हैं।
