Question

我尝试登录Facebook，可以呈现用户的城市，州，邮政编码。

以下是代码，任何人都可以告诉我哪里出错了。

我正在使用Facebook图形api（PHP SDK V4.0）

 <?php

    require_once( 'lib/Facebook/FacebookSession.php');
    require_once( 'lib/Facebook/FacebookRequest.php' );
    require_once( 'lib/Facebook/FacebookResponse.php' );
    require_once( 'lib/Facebook/FacebookSDKException.php' );
    require_once( 'lib/Facebook/FacebookRequestException.php' );
    require_once( 'lib/Facebook/FacebookRedirectLoginHelper.php');
    require_once( 'lib/Facebook/FacebookAuthorizationException.php' );
    require_once( 'lib/Facebook/GraphObject.php' );
    require_once( 'lib/Facebook/GraphUser.php' );
    require_once( 'lib/Facebook/GraphSessionInfo.php' );
    require_once( 'lib/Facebook/Entities/AccessToken.php');
    require_once( 'lib/Facebook/HttpClients/FacebookCurl.php' );
    require_once( 'lib/Facebook/HttpClients/FacebookHttpable.php');
    require_once( 'lib/Facebook/HttpClients/FacebookCurlHttpClient.php');

            if (isset($graph->getProperty['phone'])){

            echo "Your City is $city <br><Br>";

            //echo "Your Zip is $zip <br><Br>";
           /*------------------------------------------*/

        }else{
            //else echo login
            echo '<a href="'.$helper->getLoginUrl(array('email')).'" >Login with facebook</a>';
        }

登录后我的空白屏幕......

Answer 1

用户表中没有state，city或country：https://developers.facebook.com/docs/graph-api/reference/v2.3/user

location字段可能是最接近的字段。如果你得到一个空白页面，你应该检查你的错误日志。

PHP facebook图形api用于获取用户＆＃39; s-city，state，zip
