嗨，我正在尝试从他们的 Facebook 个人资料中提取用户的大学，并发现这篇文章很有用 - Getting Education with Facebook Graph API in PHP
但是，在我的实现中，由于某种原因无法识别“教育”字段，并且在“未定义索引：教育”的浏览器中引发错误。这很奇怪，因为名字和姓氏以及性别都可以正常检索，但“教育”字段却没有。
有谁知道为什么会这样？
我的代码：
// Get the app User ID
$user = $facebook->getUser();
if ($user) {
try {
// If the user has been authenticated then proceed
$user_profile = $facebook->api('/me');
// Extracting profile information to store in database
$fname = $user_profile['first_name'];
$lname = $user_profile['last_name'];
$gender = $user_profile['gender'];
$email = $user_profile['email'];
$college = null;
/* Education data is stored in an array so this iterates over
the contents of that array and checks if the entry is for "College".
*/
foreach ($user_profile['education'] as $education) { // <-ERROR HERE
if ($education['type'] == "College") {
$college = $education;
break;
}
}
}
catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
