我有一个非常奇怪的问题，我一直在尝试解决一段时间，但它已经到了我无法解决的地步。

我有一个简单的 php 脚本。它执行一些 api 调用并从 facebook 中提取一些数据，然后显示它。出于某种原因，在此页面上，我放入脚本中的任何 Javascript/jquery 都无法正常工作。我在源代码中插入了一个带有 javascript 的 iframe，它可以工作，但如果 javascript 在此页面中，它根本不会注册。根本没有响应..javascript插件不会出现，或者该功能不会在点击时触发。

MYSQL 调用也不起作用。我根本没有得到任何回报。你们以前有过这种情况吗？有什么可能的原因吗？

我不认为我有任何语法错误。不过我会继续检查。任何帮助深表感谢！！

这是我的代码的第一部分，直到正文，遗憾的是我无法显示其余部分：

<?php
require 'includes/connection.php';
require 'src/facebook.php';

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId'  => '~myid~',
'secret' => '~mysecret~',
));

// Get User ID
$user = $facebook->getUser();


// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.

if ($user) {
 try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
$access_token = $facebook->getAccessToken();

$user_name = $user_profile[first_name];


/*
echo $user;

echo "<br/><br/>";

echo $access_token;
*/

} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}/*elseif($_GET[user]){
$user = $_GET[user];

if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
$access_token = $facebook->getAccessToken();

$user_name = $user_profile[first_name];


/*
echo $user;

echo "<br/><br/>";

echo $access_token;


} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
}*/

// Login or logout url will be needed depending on current user state.

$logoutUrl = $facebook->getLogoutUrl();

$loginUrl = $facebook->getLoginUrl(array('scope'=>'offline_access'));

此代码中的所有 javascript 现在都无法正常工作。此外，我在上面的代码中替换了我的 facebook 和 soundcloud 应用数据。抱歉有点乱。希望我可以发布所有内容，但这不取决于我。提前感谢您的帮助！

这是我要求的 SQL 语句 - 实际上只是我使用相同格式设置的测试语句：

$query = "SELECT * FROM users WHERE fb_user_id = '$user'";

        $likes = mysql_query($query);

        $num = mysql_num_rows($likes);

        echo $num;

        while ($like_list = mysql_fetch_array($likes, MYSQL_ASSOC)){
            $like = $like_list['fb_from_id'];
            echo $like;

            }

只是阅读你拥有的代码，看起来你可能错过了你的最后一个 ob_end_flush();

每当ob_start();被调用时，它都会开始缓冲输出并且ob_end_flush();必须被调用才能再次输出 - 所以在你的末尾</head>，尝试添加ob_end_flush();

以下代码示例来自ob_start()PHP.net 。ob_end_flush()

Example #1 用户自定义回调函数示例

<?php

function callback($buffer)
{
    // replace all the apples with oranges
    return (str_replace("apples", "oranges", $buffer));
}

ob_start("callback");

?>
<html>
    <body>
        <p>It's like comparing apples to oranges.</p>
    </body>
</html>
<?php

ob_end_flush();

?>

上面的示例将输出：

<html>
    <body>
        <p>It's like comparing oranges to oranges.</p>
    </body>
</html>

所以 SQL 语句不起作用的问题是该表是用 4 个字符命名的，就像这样。当我将其更改为 5 时，就像喜欢一样，它起作用了。我不知道表名的长度是有限制的。如果我发布了我的代码，有人可能会注意到这一点。无论如何感谢所有的帮助！
