The workings membership.php 工作原理membership.php
<?php
require 'Mysql.php';
class Membership {
function validate_user($un, $pwd) {
$mysql = New Mysql();
$ensure_credentials = $mysql->verify_Username_and_Pass($un, md5($pwd));
if($ensure_credentials) {
$_SESSION['status'] = 'authorized';
header("location: index.php");
} else return "Please enter a correct username and password";
}
function log_User_Out() {
if(isset($_SESSION['status'])) {
unset($_SESSION['status']);
if(isset($_COOKIE[session_name()]))
setcookie(session_name(), '', time() - 1000);
session_destroy();
}
}
function confirm_Member() {
session_start();
if($_SESSION['status'] !='authorized') header("location: login.php");
}
}
Mysql.php Mysql.php
This is what is connecting to the data base. 这就是连接到数据库的内容。
require_once 'includes/constants.php';
class Mysql {
private $conn;
function __construct() {
$this->conn = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME) or
die('There was a problem connecting to the database.');
}
function verify_Username_and_Pass($un, $pwd) {
$query = "SELECT *
FROM users
WHERE username = ? AND password = ?
LIMIT 1";
if($stmt = $this->conn->prepare($query)) {
$stmt->bind_param('ss', $un, $pwd);
$stmt->execute();
if($stmt->fetch()) {
$stmt->close();
return true;
}
}
}
}

创建一个会话变量，该变量将保存从查询中获取的用户名，然后在页面中回显该会话变量。

I think, you missed the echo before. 我认为，您之前错过了回声。 Change 更改
<?
$_SESSION['username']
?>
to 至
<?
echo $_SESSION['username']
?>

I used the same nettuts tutorial for my user login page. 我在用户登录页面上使用了相同的nettuts教程。 This is what works for me to show logged in user on index.php page. 这就是我可以在index.php页面上显示登录用户的方法。
INSERT IN BODY OF INDEX.PHP PAGE: 在INDEX.PHP正文中插入页面：
<?php
echo "Welcome ", $_SESSION['username'];
?>

我认为您错过了在index.php页面上开始会话的时间，因此请在页面开头输入此行
session_start();
