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
這就是連接到數據庫的內容。
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;
}
}
}
}

在您的index.php中，編寫以下代碼：
<div id="top-register">
<?
echo "Hello" .$_SESSION['username'];
?>

創建一個會話變量，該變量將保存從查詢中獲取的用戶名，然后在頁面中回顯該會話變量。

我認為，您之前錯過了回聲。 更改
<?
$_SESSION['username']
?>
至
<?
echo $_SESSION['username']
?>

在班級成員資格中更改此...
if($ensure_credentials) {
$_SESSION['status'] = 'authorized';
header("location: index.php");
} else return "Please enter a correct username and password";
為此...
if($ensure_credentials) {
$_SESSION['status'] = 'authorized';
$_SESSION['username'] = $un;
header("location: index.php");
} else return "Please enter a correct username and password";

我在用戶登錄頁面上使用了相同的nettuts教程。 這就是我可以在index.php頁面上顯示登錄用戶的方法。
在INDEX.PHP正文中插入頁面：
<?php
echo "Welcome ", $_SESSION['username'];
?>

我認為您錯過了在index.php頁面上開始會話的時間，因此請在頁面開頭輸入此行
session_start();
嘗試在用戶登錄后在導航欄中顯示用戶的用戶名？
