会话没有通过,我想限制用户在登录时查看登录页面,我尝试了很多东西,但它没有用:
我的登录页面
<?php
error_reporting(E_ALL);
ini_set('display_errors',1);
require_once('connect.php');
extract($_POST);
$result = mysqli_query($link, "SELECT * FROM users ");
$row = mysqli_fetch_assoc($result);
//var_dump($row['username']);
//var_dump($row['password']);
if(isset($_POST['login'])){
$username = $_POST['username'];
$password = md5($_POST['password']);
if ($username == $row['username'] && $password == $row['password']){
session_start();
$_SESSION['nID'] = true;
//echo"Login";
header('Location: home.php');
} else {
echo"Login failed";
}
}
?>
