phpbb登录转移？

Question

我一直在我的网站上工作，遇到了一些问题。我按照本教程：http://www.youtube.com/watch?v=Jq4csat4jNU&list=FLqRayDXYkEpNeTDbfJ5oBmw&index=2将phpbb（和用户数据库）的登录集成到我的网站主页。唯一的问题是，当您在主页登录表单上登录后进入论坛时，它会要求您再次登录。有没有办法让它从原始的敬意登录表单登录论坛？谢谢你，Josh

这是我的主页登录表单代码：

<div class="login_box">

<li>

<?php
//ob
ob_start();

//session
session_start();

    //connect
    $error = 'Could not connect to the databse';
    mysql_connect('localhost','root','') or die($error);
    mysql_select_db('phpbb') or die ($error);

    //include functions.php phpbb script
    require 'includes/functions.php';

    if ($_POST['login'])
    {
    //get form data
    $username = addslashes (strip_tags(strtolower($_POST['username'])));
    $password = addslashes (strip_tags($_POST['password']));

    if (!$username||!$password)
        echo "Please enter a valid username and password<p /p>";
    else
    {
    //find username
    $find = mysql_query("SELECT * FROM phpbb_users WHERE username_clean='$username'");
    if (mysql_num_rows($find)==0)
        echo "Username not found";
    else
    {
     while ($find_row = mysql_fetch_assoc ($find))  
     {
      //grab password hash for user
      $password_hash = $find_row['user_password'];
      }
    $check = phpbb_check_hash($password, $password_hash);
    if ($check==FALSE)
        echo "Incorrect Password";
    else if ($check==TRUE)
    {
     $_SESSION['username']=$username;
     header("Location: index.php");
     exit();
     }  
    }
    }
    }
    if (!isset($_SESSION['username']))
    {
?>  

<div class="logged_out">

<form action="login.php" method="post"> 

<input type="text" placeholder="username" maxlength="20" size="16px" name="username"  /> 


<input type="password" placeholder="password" maxlength="50" size="15px" name="password"  /> 

<div class="button"><input type="image" name="login" value="Log in" src="images/login.png"  width="26px" onmouseout="this.src='images/login.png'" onmouseover="this.src='images/loginhover.png'" onmouseout="t"></div>

</form> 
<a href="register.php">New member? Register now</a>

</div>

<?php
}
else
{
  echo "<div class='logged_in'>";
       echo 
            "<div class='welcome'><b>".$_SESSION['username'].".</b></div>" 
           ."<div class='account'><a href=\"userinfo.php?user=$session->username\">Messages</a></div> &nbsp;&nbsp;"
           ."<div class='account'><a href=\"useredit.php\">My Account</a></div> &nbsp;&nbsp;";
       echo "<div class='account'><a href=\"logout.php\">Logout</a></div>";
       echo "</div>";
}
?>

</li>



</div>
