[英]Display Events on PHP Calendar
I would like to ask if I have a table of events on my database, eg 我想问一下我的数据库中是否有事件表,例如
description | startdt | enddt
event1 | 2010-04-01 10:00:00 | 2010-04-01 13:00:00
event2 | 2010-04-09 14:00:00 | 2010-04-09 18:00:00
event3 | 2010-04-30 11:00:00 | 2010-05-02 16:00:00
I have already created a php calendar, how can I display these above events onto my calendar, so that it will look something like the google calendar? 我已经创建了一个php日历,如何将上述事件显示在我的日历上,使其看起来像Google日历? eg on the for 2010-04-01, it will display "event1" on the month calendar. 例如,对于2010-04-01,它将在月份日历上显示“ event1”。
Thank you. 谢谢。
Assuming you've got a $year and $month variable already precomputed for displaying the calendar grid, you'd fetch the data from the database something like this: 假设您已经预先计算了一个用于显示日历网格的$ year和$ month变量,您将从数据库中获取数据,如下所示:
$query = <<<EOF
SELECT DAY(startdt) AS day, description
FROM table
WHERE (YEAR(startdt) = $year) AND (MONTH(startdt) = $month)
EOF;
$stmt = mysql_query($query) or die ('Query error: ' . mysql_error());
$events = array();
while($row = mysql_fetch_assoc($stmt)) {
$events[$row['day']][] = $row['description']; // might have multiple events on one day, so store as an array of events
}
Then while building the calendar, check if $day is present in the $events
array and output the descriptions however you wish: 然后在构建日历时,检查$events
数组中是否存在$ day,并根据$events
输出描述:
for ($day = 1; $day <= 31; $day++) {
if(isset($events[$day])) {
... display event descriptions
}
}
Of course, if you have events that span multiple days, then you'll have to modify things to handle that, but this should get you started with at least single-day events. 当然,如果您的活动跨越了多天,那么您就必须进行修改以解决该问题,但这至少可以让您从单日活动开始。
