我正在开发一个网站
Red Sec
我为所有子域使用 1 个帐户:

  • 公告
  • 论坛
  • 博客
  • 新闻
  • 捐赠

所有页面都具有相同的样式，只是通过将它们全部连接到 http://red-sec.net/res/menu.php 来实现不同的内容。 .这是它的代码，因为您无法阅读它:

<?php
require 'connection.php';
function menu(){
  if(!isset($_SESSION['username'])){
  echo '<nav class="navbar navbar-default navbar-fixed-top shadow">
    <div class="container">
      <a href="http://red-sec.net" class="navbar-brand">Red-Sec.net</a>
      <ul class="nav navbar-nav">
        <li class="menuitem"><a href="http://red-sec.net">Home</a></li>
        <li class="menuitem"><a href="http://announcements.red-sec.net">Announcements</a></li>
        <li class="menuitem"><a href="http://forum.red-sec.net">Forum</a></li>
        <li class="menuitem"><a href="http://blog.red-sec.net">Blog</a></li>
        <li class="menuitem"><a href="http://news.red-sec.net">News</a></li>
        <li class="menuitem"><a href="http://donate.red-sec.net">Donate</a></li>
      </ul>
      <ul class="nav navbar-nav navbar-right">

  <script src=" ../js/menu.js"></script>
  <div class="container bg">
  <div class="row full">
  <div class="col-lg-8 bd">';
}else{
  $username = $_SESSION['username'];
  echo '<nav class="navbar navbar-default navbar-fixed-top shadow">
    <div class="container">
      <a href="http://red-sec.net" class="navbar-brand">Red-Sec.net</a>

  <div class="container bg">

}
}
function endbd(){
    require'connection.php';
  echo '</div>
  <div class="col-lg-4 bd sidebar">
  <h2 class="title">Latest News Post</h2>
<hr class="under">';
$query = "SELECT * FROM news ORDER BY date DESC LIMIT 1";
$run = mysqli_query($connect,$query);
if(!$run){
    echo 'sorry';
}
$row = mysqli_fetch_array($run);
  $article_id = $row['article_id'];
  $user_id = $row['user_id'];
  $title = $row['title'];
  $content = $row['content'];
  $date = $row['date'];
  $query = "SELECT username FROM users WHERE ID = '$user_id'";
  $test = mysqli_query($connect,$query);
  $row2 = mysqli_fetch_array($test);
  $user_name = $row2['username'];
  echo '<div class="row">
  <div class="col-lg-12"><h3 class="para"><a class="para" href="/news/article.php?id='.$article_id.'">'.$title.'</a></h3>
  <p class="para">Written by: '.$user_name.'</p>
  </div>
  </div>
  </div>
  </div>
  </div>';
}
 ?>

我注意到当您登录主页并转到子域时，菜单会显示注册或登录而不是您的用户名，这是它应该做的。
但是，当您单击注册或登录时，它只会刷新页面并显示您的用户名和旁边的注销选项。这意味着 session 在子域中工作，但由于某种原因一开始没有显示，所以你必须刷新它？有人可以解释为什么会这样吗？

编辑:
这是我如何使用 res/menu.php

的示例 
<?php
session_start();
include 'res/connection.php';
include 'res/menu.php';
?>
<!DOCTYPE html>
<html>
<head>
  <title>R3D S3C | Home page</title>
  <link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"/>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
  <link rel="stylesheet" type="text/css" href="css/style1.css"/>
  <link href='https://fonts.googleapis.com/css?family=Roboto' rel='stylesheet' type='text/css'>
</head>
<body>
<?php menu(); ?>
<h2 class="title">Red Sec</h2>
<p class="para">Long Lorem Ipsum text goes here...</p>
<?php endbd(); ?>
</body>
</html>

编辑 2:
请求的登录页面:

<?php
session_start();
include 'res/connection.php';
include 'res/menu.php';
if(isset($_SESSION['username'])){
  header('Location: profile.php');
}
?>
