我在 php mysql 中使用 session 登录无论是否使用正确的用户名和密码都可以正常工作...以下是代码...
这是我的login.php
<?php
ob_start();
session_start();
$username = $_POST['username'];
$password = $_POST['password'];
$records = mysql_connect('localhost', 'root', '');
mysql_select_db('login', $records);
$username = mysql_real_escape_string($username);
$query = "SELECT id, username, password
FROM login
WHERE username = '$username';";
$result = mysql_query($query);
if(mysql_num_rows($result) == 0) // User not found. So, redirect to login_form again.
{
header("Location: http://localhost/GuidanceRecord/login.html");
}
$userData = mysql_fetch_array($result, MYSQL_ASSOC);
//$hash = hash('sha256', $userData['salt'] . hash('sha256', $password) );
if($password != $userData['password']) // Incorrect password. So, redirect to login_form again.
{
header("Location: http://localhost/GuidanceRecord/login.html");
}else{ // Redirect to home page after successful login.
//session_regenerate_id();
//$_SESSION['sess_user_id'] = $userData['id'];
//$_SESSION['sess_username'] = $userData['username'];
$_SESSION['username'] = $username;
//session_write_close();
header("Location: http://localhost/GuidanceRecord/ViewRecords.php");
}
?>
这是我的登录.html

这是我项目每个页面中的 session ...
<?php
//Start session
session_start();
//Check whether the session variable SESS_MEMBER_ID is present or not
if (!isset($_SESSION['username'])) {
header("Location: http://localhost/GuidanceRecord/login.html");
}
?>
我有一个名为login的登录数据库... 我的表中有 3 列，名为:ID(自动增量和主键)、用户名和密码...
无论如何，感谢您的帮助...
