Question

登录后点击登录链接，需要再次登录。
会议节省了我插入标题重定向到其他页面，如果我在登录后单击登录页面但仍然相同。

这是我的登录过程php

<?php
    ini_set("session.save_path",$_SERVER["DOCUMENT_ROOT"]. "../../sessionData");
    session_start();


    include 'database_conn.php';    // make db connection
    ?>

                </ul>


            </div>  

            <div id= "content">

<?php
$username   = filter_has_var(INPUT_POST, 'userName') ? $_POST['userName']: null;

这是我的登录页面，我使用if（isset（$ _ SESSION [＆＃39;登录＆＃39;]）＆amp;＆amp; $ _SESSION [＆＃39;登录＆＃39;] = = true）检查登录。

<?php
    ini_set("session.save_path",$_SERVER["DOCUMENT_ROOT"]. "../../sessionData");
    session_start();

    if (isset($_SESSION['logged-in']) && $_SESSION['logged-in'] == true) 
    {
        header(' Location :admin.php');
    }

    include 'database_conn.php';    // make db connection
    ?>
