Question

我想更改我的代码，首先它会检查用户是否喜欢该页面。在此之后（如果是），将出现一个问题，接受条款，如果他点击接受按钮，将出现Facebook权限请求对话框。我怎么能这样做？

问题在于，每次用户点击应用链接时，$ user变量始终为false，但他已登录...

<?php
require 'facebook.php';

$facebook = new Facebook(array(
'appId' => 'xxxxx',
'secret' => 'yyyyy',
'baseUrl' => 'http://hosting.address/',
'appBaseUrl' => 'http://apps.facebook.com/app-name/',
'fileUpload' => 'true',
));

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

$params = array(
  scope => 'publish_stream,user_photos',
  redirect_uri => 'http://www.facebook.com/xxxxx?sk=app_yyyyy&app_data=1'
    );

$signed_request = $facebook->getSignedRequest();
$app_data = $signed_request["app_data"];


?>
                    <!doctype html>
                    <html xmlns:fb="http://www.facebook.com/2008/fbml">
                    <head>
                    <title>the title</title>
                    </head>
                    <body>
<?php if ($user){

    try {
        $user_profile = $facebook->api('/me');
        $likes = $facebook->api("/me/likes/123123123"); //page ID

            if( !empty($likes['data']) ){

                $scope = 'publish_stream,user_photos';
                $scope_params = explode(',',$scope);

                $permissions = $facebook->api("/me/permissions");
                    if( array_key_exists('publish_stream', $permissions['data'][0]) &&  array_key_exists('user_photos', $permissions['data'][0]) && isset($app_data)) {


                    } else {

echo "<a href=\"/redirect.php\">accept</a></td>";
echo "<a href=\"http://www.facebook.com/pageurl\">deny</a></td>";

                    }
            }else{
                echo "<img width=\"520px\" src=\"no-fan.jpg\" />";
            }

    } catch (FacebookApiException $e) {
        echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
        $user = null;
        }
    }

    if ($user) {
        } else {
            $loginUrl = $facebook->getLoginUrl($params);
            echo '<script type="text/javascript">top.location.href = "'.$loginUrl .'";</script>';
        }

        ?>

</body>
</html>

尝试遵循以下优秀示例：

然后在fanpage.php上有你的代码让他们登录。
