Question

如何在登录后使用signin.php在http_referer页面中设置我的logout.php位置，并检查＆amp;成功登录重定向到joomla.php，我给了注销链接（使用href）现在我想点击注销＆amp;去看看。 php＆amp;我得到http_referer是joomla.php所以我可以设置logout.php

代码：Signin.php

$referer = $_SERVER['HTTP_REFERER'];
echo $referer;
if ($referer == 'http://localhost/MinProject/reg.php')
{
    echo "Registration SuccessFully";
}

else if($referer=='http://localhost/MinProject/changepassword.php')
{
    echo"Change Password SuccessFully";
}

joomla.php

<html>
    <body>
        <table width="100%">
            <tr>
                <td width="20%" height="32" align="right" class="unm">
                    <?php
                    session_start();
                    if(isset($_SESSION['username']))
                    {
                        $name =$_SESSION['username'];
                        echo "Welcome ".$name;
                     }
                    ?>
                </td>
                <td width="64%" height="32" align="right">
                    <a href="changepassword.php">ChangePassword</a>
                </td>
                <td width="10%" align="right">

logout.php

session_start();
unset($_SESSION['username']);
session_destroy();
response.setHeader("Location: http://localhost/MinProject/logout.php");
header("Location: Signin.php");

HTTP_REFERER可能会被欺骗，因此您不应该使用它。

看看你的代码，我认为你正在努力实现。

$Message  = $_SESSION['MESSAGE'];//set the message Registration SuccessFully if registration else set it as Change Password SuccessFully or accordingly
if (isset($Message) and userhasidentity)
{
    echo $Message;
}else
{
   header('location:logout.php');
}

无法设置http_referer
