嗨用户！欢迎来到Facebook 
  

我希望电子邮件地址与用户名一起显示，我搜索了很多代码但没有得到任何解决方案。如果您有任何好的Facebook教程网站，请张贴链接。

解决方案

您可以直接获取电子邮件地址，而无需使用FQL。

  // initialize facebook 
 $ facebook = new Facebook（array（
'appId' => APP_ID，
'secret'=> APP_SECRET））; 
 
 $ session = $ facebook-> getSession（）; 
 if（$ session）{
 try {
 $ fbme = $ facebook-> api（'/ me'）; 
} catch（FacebookApiException $ e）{
 error_log（$ e）; 
} 
} 
 else 
 {
 echo你没有登录; 
} 
 
 //如果没有在
中签名，获取登录页面if（！$ fbme）{
 $ loginUrl = $ facebook-> getLoginUrl（array 'canvas'=> 1，
'fbconnect'=> 0，
'req_perms'=>'email，user_birthday，publish_stream'，
'next'=> CANVAS_PAGE， 
'cancel_url'=> CANVAS_PAGE））; 
 echo'< fb：redirect url ='。$ loginUrl。'/>'; 
} else {
 
 // $ fbme是有效的，即用户可以访问我们的应用程序
 echo您可以使用此App; 
} 
 
 //获取个人资料
 $ user_id = $ fbme [id]; 
 $ name = $ fbme ['name']; 
 $ first_name = $ fbme ['first_name']; 
 $ last_name = $ fbme ['last_name']; 
 $ facebook_url = $ fbme ['link']; 
 $ location = $ fbme ['location'] ['name']; 
 $ bio_info = $ fbme ['bio']; 
 $ work_array = $ fbme ['work']; 
 $ education_array = $ fbme [education]; 
 $ email = $ fbme ['email']; 
 $ date_of_birth = $ fbme ['birthday']; 
  

此代码为我工作，并且我将使用电子邮件ID所需的所有信息。 p>

 注意：用户必须允许我们在批准申请时获取他们的信息。

Hi User! welcome to facebook

I want the Email address to be displayed along with the user name, i searched many code but did not get any solution. and if you any good facebook tutorial site please post the links too..

解决方案

You can get the Email Address, directly without using the FQL.

// initialize facebook
 $facebook = new Facebook(array(
        'appId' => APP_ID,
        'secret' => APP_SECRET));

 $session = $facebook->getSession();
 if ($session) {
 try {
    $fbme = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}
else
{
  echo "You are NOT Logged in";
}

//getting the login page if not signned in
if (!$fbme) {
  $loginUrl = $facebook->getLoginUrl(array('canvas' => 1,
                                      'fbconnect' => 0,
                                      'req_perms' =>                   'email,user_birthday,publish_stream',
                                      'next' => CANVAS_PAGE,
                                      'cancel_url' => CANVAS_PAGE ));
 echo '<fb:redirect url="' . $loginUrl . '" />';
 } else {

      // $fbme is valid i.e. user can access our app
     echo "You can use this App";
 }

 // getting the profile data
 $user_id = $fbme[id];
 $name=$fbme['name'];
 $first_name=$fbme['first_name'];
 $last_name=$fbme['last_name'];
 $facebook_url=$fbme['link'];
 $location=$fbme['location']['name'];
 $bio_info=$fbme['bio'];
 $work_array=$fbme['work'];
 $education_array=$fbme["education"];
 $email=$fbme['email'];
 $date_of_birth=$fbme['birthday'];

This code worked for me..and i go all the information needed with the Email ID.

NOTE: User has to allow us to get their Information during the Approval of Application.
