我正在研究一个项目，我认为这是一个简单的解决方案。我只是没有看到它。
您可以访问www.thriftstoresa.com查看实际网站，问题在于登录页面（http://www.thriftstoresa.com/Login.php）
有效的用户名是'none'，密码是'password'。
我遇到的问题是我总是返回“密码不正确，请再试一次。”
任何帮助将不胜感激。你可能会说，我是PHP的新手。感谢

您应该考虑使用https://github.com/auraphp/Aura.Auth之类的内容。你所展示的代码正在引发更多问题，正如tadman在评论中已经提到的那样。
答案 1 :(得分：0)
所以我会指出一些我认为可以帮助你的事情。首先，如果你只是学习php然后忘记mysql并学习mysqli。因为它将不再存在于较新的PHP版本中。
话虽如此，让我们来看看你得到了什么。
//cookie only when they have entered in a correct login and password
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
//needs to have another `|`
if(!$_POST['username'] || !$_POST['pass']) {
//here your checking md5($_POST['password']) against $info['password']
if ($_POST['pass'] != $info['password']) { //is info password md5() hashed?
这是一个建议，这可能会节省您的代码时间
$sql="SELECT * FROM users WHERE email=\"".$email."\" AND md5(password)=\"".md5($password)."\"";
$query=mysql_query($sql);
if(mysql_num_rows($query)==0)
{
echo "Incorrect Login";
}
else
{
$row = mysql_fetch_array($query);
//set your cookies here
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$_SESSION['user_id-'.$_SERVER['SERVER_NAME']]=mysql_result($query,0);
//set a session of logged in by your server name and mysql_result and i would use an identifying ID number for every user.
echo "Successfully Logged In";
}
//to check if some one is logged in
if(!empty($_SESSION['user_id-'.$_SERVER['SERVER_NAME']])) redirect("index.php?action=alreadyloggedin");
//session variable can be w/e you want
我也不会使用md5而不是sha1
