嗨我試圖與Facebook的SDK的PHP工作,我有一些問題。下面的代碼直接從它們提供的示例中複製,但我甚至無法獲取腳本的html元素以顯示......這使我認爲某處存在語法錯誤。當我檢查嵌入在html部分中的php時,我相信我會在if-else語句中看到一些問題。舉例來說,似乎是一個:當應該有一個{以下行:問題與Facebook的Facebook的PHP登錄
<?php if ($user): ?>
我是在說這句話的正確或不使用Facebook的語法我不熟悉?
<?php
require 'facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'my_app',
'secret' => 'my_secret',
));
// Get User ID
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');
?>
