php會話在php中提交表單後無法運行5.3

我的代碼是這樣的。這是一個登錄頁面。我在提交表單後創建會話。但會話不在這裏創建。但我已經在頂部創建了一個會話來測試它的工作。我的PHP版本是5.3+。它之前運作良好。但託管公司有更新並且問題開始。所有其他的事情都可以。php會話在php中提交表單後無法運行5.3

<?php 
    ob_start(); 
    session_start(); 
    $_SESSION['sessid'] = 123456789; 
    print_r($_SESSION); 
    include('db_connect.php'); 
    ?>

也許最壞的登錄腳本我'have see：D but not not a error here：'if if（$ result ['num']> 0） { $ _SESSION ['logged_in'] = TRUE; } 其他{....}' – 2013-03-10 19:39:51

你有一些用戶數據類似

   if($result['num'] > 0) 
     { 
     session_register("id"); 
     $id = $result['id']; 
     $_SESSION['logged_in'] = $id; 
       }

，而不是

  if($result['num'] > 0) 
     { 
     $_SESSION['logged_in'] = TRUE; 
     }

註冊您的會話希望這將有用你
