这里是用户点击我的注册Facebook的按钮发送到。

<?php 
define('FACEBOOK_APP_ID', 'XXXX');

function parse_signed_request($signed_request, $secret) { 
    list($encoded_sig, $payload) = explode('.', $signed_request, 2); 

    // decode the data 
    $sig = base64_url_decode($encoded_sig); 
    $data = json_decode(base64_url_decode($payload), true); 

    if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') { 
    error_log('Unknown algorithm. Expected HMAC-SHA256'); 
    return null; 
    } 

    // check sig 
    $expected_sig = hash_hmac('sha256', $payload, $secret, $raw = true); 
    if ($sig !== $expected_sig) { 
    error_log('Bad Signed JSON signature!'); 
    return null; 
    } 

    return $data; 
} 

function base64_url_decode($input) { 
    return base64_decode(strtr($input, '-_', '+/')); 
} 

if ($_REQUEST) { 
    $response = parse_signed_request($_REQUEST['signed_request'], 
             FACEBOOK_SECRET); 

$uname = $response["registration"]["username"];

我需要什么，现在得到完成的就是添加一个按钮，我的索引，上面写着登录，如果他们点击它，它应该尝试登录到我的网站与他们的Facebook，如果用户不具有帐户它应该将它们重定向到我的注册脚本，否则它应该自动登录并重定向到登录屏幕。

信息，你可能需要知道：

密码字段登录使用MD5加密

任何帮助，将不胜感激，如果你需要任何更多的信息只是问:)

在我刚才的问题facebook registration connect我要求帮助建立我的注册页面。那么我现在已经成功完成了，但现在我需要做到这一点，所以用户也可以用facebook登录。要做到这一点，我希望使用FaceBook登录按钮，如果他们点击登录，并且它检测到他们没有注册，它将重定向到注册页面，否则它将登录他们。

我将使用什么代码（示例） ？你需要知道任何特殊信息？
