我正在开发一个Facebook应用程序，我想在其中显示我的朋友的照片与他的出生日期。例如，今天是4月26日;如果今天我朋友的生日有任何一个，他/她的照片应该显示在26日的日历插槽中等等。
到目前为止，这是我的查询：
$dt = "April 12";
$fql1 = "SELECT uid,pic_big,pic,pic_small,name
FROM user
WHERE birthday='".$dt."' AND
uid IN (SELECT uid2 FROM friend WHERE uid1= $user)";
我希望能够处理完整日期（即1986年4月12日）和部分日期（4月12日）。
这是我的日历代码

答案 0 :(得分：1)
你的问题有点难以理解;但从我的理解 - 你在特定日期找到朋友的生日时遇到了问题。
我建议以不同的方式解决这个问题。看起来您正在为日历中的每个日期执行单个FQL查询。我认为最好加载所有用户的朋友，并循环遍历每个用户并推断日期。根据{{3}}，生日日期格式与用户的区域设置相关，因此您无法可靠地查询该字段。
另一种选择:( 已编辑更完整。现在几乎完全复制和粘贴。）
<?php
$facebook = new Facebook(array(
'appId' => FB_APP_ID, //put your FB APP ID here
'secret' => FB_APP_SECRET, //put your FB APP SECRET KEY here
'cookie' => true
));
$session = $facebook->getSession();
if ($session)
{
//check to see if we have friends_birthday permission
$perms = $facebook->api('/me/permissions');
}
//we do this to see if the user is logged & installed
if (empty($session) || empty($perms['friends_birthday']))
{
//get url to oauth endpoint for install/login
$loginUrl = $facebook->getLoginUrl(array(
//put the URL to this page, relative to the FB canvas
//(apps.facebook.com) here vvv
'next' => 'http://apps.facebook.com/path_to_your_app/index.php',
'req_perms' => 'friends_birthday'
));
//use javascript to redirect. the oauth endpoint cant be loaded in an
//iframe, so we have to bust out of the iframe and load it in the browser
//and tell the oauth endpoint to come back to the fb canvas location
echo "<script>window.top.location='{$loginUrl}';</script>";
exit;
}
$user = $session['uid']; //load the user id from the session array
$cur_month_birthdays = array();
$cur_month = 4; //april
try {
$fql1 = "SELECT uid, pic_big, pic,pic_small, name, birthday FROM user "
. "WHERE uid IN ( "
. "SELECT uid2 FROM friend WHERE uid1 = {$user} "
. ")";
$friends = $facebook->api(array(
'method' => 'fql.query',
'query' => $fql1
));
//make sure i have some friends...
if (!empty($friends))
{
foreach ($friends as $friend)
{
//if this friend doesn't have their bday specified, skip them.
if (empty($friend['birthday']))
{
continue;
}
//get unix time for the users' birthday
$birthday_ts = strtotime($friend['birthday']);
//if this friends birthday is this month...
if (date('m', $birthday_ts) == $cur_month)
{
//generate a month-day string for the birthdate
$birthday_str = date('m-d', $birthday_ts);
//initialize the array of friends with birthdays on this date
if (empty($cur_month_birthdays[ $birthday_str ]))
{
$cur_month_birthdays[ $birthday_str ] = array();
}
$cur_month_birthdays[ $birthday_str ] []= $friend;
}
}
}
}
catch (Exception $e)
{
//error with facebook
error_log($e);
}
//output list of days in this month with friends that have birthdays
print_r($cur_month_birthdays);
以上代码将获取所有用户的朋友，循环浏览每个用户，并查找当月的生日（定义为$cur_month）。然后，您可以循环并构建日历，并且每天检查$cur_month_birthdays数组以查看是否有任何朋友在当天生日，并正确显示它们。
希望有所帮助！
** 修改 **
这是我对上述脚本的输出。我编辑它是为了更彻底的设置（包括FB PHP SDK的初始化和用户会话的获取。我假设你已经至少那个代码。现在你可以看到数组的结构 - 你应该能够轻松地弄清楚如何集成到你的日历中。
