除非我点击刷新,否则重定向的php页面不会加载

Question

早上好,我终于设法在Facebook登录后将Facebook用户名存储在我的数据库中.唯一的问题是需要重新加载Facebook登录后用户被重定向到的页面(我第一次只得到一个空页面).你可以参考我之前的问题,因为我已经在那里发布了所有代码

更新:我注意到页面只需要第一次刷新(当用户信息尚未存储在数据库中时,它会快速且很好地加载页面.请帮助!;-)

UPDATE2:有没有办法在添加新用户后自动刷新页面(只需一次)？非常感谢!

更新3:我发布代码....它只有在我刷新页面时才有用....任何想法？

        <?php

          mysql_connect('host', 'username', 'password');  
           mysql_select_db('table');  



require 'library/facebook.php';

    // Create our Application instance 
   $facebook = new Facebook(array(
    'appId'  => 'MYID',
   'secret' => 'MYSECRET',
  'cookie' => true));


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



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



   } catch (FacebookApiException $e) {
   error_log($e);
   $user = null;
   }
     }else{
   header('location: index.php');

    }
      $query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND       oauth_uid = ". $user_profile['id']);  
      $result = mysql_fetch_array($query);  

    if(empty($result)){ 
      $query = mysql_query("INSERT INTO users (oauth_provider, oauth_uid, username)         VALUES ('facebook', {$user_profile['id']}, '{$user_profile['name']}')");  
       $query = msyql_query("SELECT * FROM users WHERE id = " . mysql_insert_id());  
      $result = mysql_fetch_array($query);  

       }  



    if ($user) {
     $paramsout = array('next'=>'http://www.mywebsite/test/logout.php');
     $logoutUrl = $facebook->getLogoutUrl($paramsout);
     }


     ?>

最后我成功了。当然这是一个重定向问题。但在index.php和user_page.php中添加sql都不起作用。我最终将用户从 Facebook 页面重定向到“login.php”，如果是新记录，则添加到数据库，然后重定向到 user_page.php。这是login.php的代码：

<?php


 mysql_connect('HOST', 'USER', 'PSW');  
 mysql_select_db('MYDATABASE');

 require 'library/facebook.php';

  // Create our Application instance (replace this with your appId and secret).
   $facebook = new Facebook(array(
  'appId'  => 'MYID',
  'secret' => 'MYSECRET',
   'cookie' => true));


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

if($user){

 $user_profile = $facebook->api('/me');

    $query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND oauth_uid = ". $user_profile['id']);
    $result = mysql_fetch_array($query);

    if(empty($result)){
        $query = mysql_query("INSERT INTO users (oauth_provider, oauth_uid, username) VALUES ('facebook', {$user_profile['id']}, '{$user_profile['name']}')");

        header('Location: user_page.php');
                                }else{
        header('Location: user_page.php');
         }


          }else{

        header('Location: logout.php');


        }


           ?>
