我對會話處理感到困惑。我想訪問我的索引頁面，無論用戶是否登錄。但是，如果用戶登錄，那麼我想更換我的登錄名並註銷按鈕。如果沒有登錄，則顯示登錄和註冊菜單。但在這兩種情況下，索引頁都應該可以訪問。 當我在頭中包含會話文件時，索引頁僅顯示爲登錄用戶。如果我只寫session_start（）;在與頁面頂部檢查我想訪問index.php登錄或不登錄索引頁登錄詳細信息
if(isset $_SESSION['login_user'])
{ echo $login_session
}
//index.php
<?php
$currentPage = 'index';
include_once "header.php"; ?>
\t <div class="stle">
<h1> welcome to home page</h1>
//menus
//slider
// posts
</div>
<?php include_once "footer.php"; ?>//session.php
<?php
include('dbconn.php');
session_start();
$user_check = $_SESSION['login_user'];
/* $ses_sql = mysqli_query($conn,"select name,email from signup_work where email = '$user_check' ");*/
$ses_sql = mysqli_query($conn,"SELECT name,email
FROM signup_hire
WHERE signup_hire.email = '$user_check'
UNION
SELECT name,email
FROM signup_work
WHERE signup_work.email = '$user_check' ");
$row = mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);
/*printf("Error: %s\n", mysqli_error($conn));
exit();*/
$login_session = $row['name'];
if(!isset($_SESSION['login_user'])){
header("location:login.php");
}
?>// header.php
<?php session_start();
$login_session=""; ?>

爲了這個，我必須包括session.php文件文件頭和頭是相同的所有它會要求先登錄的文件 –
和什麼是logged_in –
爲什麼不只是使用Session_start（）; ？那麼你的sesssion就開始了，你可以在上面的答案中使用它。 – SteffenCH
