php日历没有显示比一个月更远的事件

Question

即时通讯设法设置此php事件日历我在网上找到。但我只能让它显示二月份和三月的事件。没有其他来自mysql数据库的事件会显示。我相信错误是在这段代码中。我一直在搞这个2天，讨厌寻求帮助，因为我真的只是想弄明白。但任何人都可以帮忙吗？

/* get all events for the given month */ 
$events = array(); 

$month = str_pad($month,2,0 , STR_PAD_LEFT); 
$query = "SELECT title, DATE_FORMAT(event_date,'%Y-%m-%d') AS event_date FROM events WHERE event_date LIKE '$year-$month%'"; 
$result = $db_link->query($query) or die('cannot get results!'); 
while($row = $result->fetch_assoc()) { 
    $events[$row['event_date']][] = $row; 
} 

继承人如果那是不够的或任何人只是想整个事情，看看它：

Answer 1

您基本的查询是：

SELECT title, DATE_FORMAT(event_date,'%Y-%m-%d') AS event_date 
FROM events 
WHERE event_date LIKE '$year-$month%'; 

不要直接上使用like日期。有一个隐式转换为字符串，它可能不是您所期望的格式。试试这个：

SELECT title, DATE_FORMAT(event_date,'%Y-%m-%d') AS event_date 
FROM events 
WHERE date_format(event_date, '%Y-%m') LIKE '$year-$month%'; 

你也可以这样做：

SELECT title, DATE_FORMAT(event_date,'%Y-%m-%d') AS event_date 
FROM events 
WHERE year(event_date) = $year and month(event_date) = $month; 

Answer 2

AHA！我想到了！我为每个月的每一天添加了一个活动，并且我意识到它并没有显示第1-9天的活动。我只需要将DATE_FORMAT（event_date，'％Y-％m-％d'）更改为DATE_FORMAT（event_date，'％Y-％m-％e'）
