有時內容加載，有時他們沒有

我有下面的腳本和網站http://cacrochester.com，有時右側邊欄的內容加載，有時他們沒有。我認爲，如果這是你在網頁上的第幾次，它會說沒有事件安排。有時內容加載，有時他們沒有

我完全難以理解爲什麼會發生這種情況。數據庫中的數據沒有變化。

讓我知道你是否需要我發佈任何代碼。

感謝您的幫助！

當你做$startDate >= $today你試圖比較兩個數組，這不是一個好主意。只需使用普通的時間戳和它應該很好地工作：

$startDate = $result['start_date']; 
$today = strtotime('today');

而且，我不知道這是否是一個錯字：current($result) == end($result)，但它不應該是$results，這是數組名？

是的應該是$結果，而不是$結果。你的回答也起作用。我忘了在這一點上停止了這一次的工作，我注意到它正在比較數組。謝謝！ – Catfish 2010-10-21 00:07:40
