密码保护Php页面,为下一页设置用户并仍检查密码

密码保护Php页面,为下一页设置用户并仍检查密码,php,mysql,passwords,Php,Mysql,Passwords,我已经能够有一个受密码保护的页面,或者一个在输入时显示用户信息的页面,但不能使它们一起工作。我知道我错过了一些简单的东西,但我已经看得太久了: <?php $db_host = "localhost"; $db_username = "1"; $db_pass = "1"; $db_name = "1"; mysql_connect("$db_host","$db_username","$db_pass") or die(mysql_error()); mysql_se

现有客户,请联系以请求登录用户名和密码




现在用户可以输入他们的电子邮件,直接进入显示页面,它传递信息并完美地显示所有内容唯一的问题是没有先检查密码,我知道这是我设置的顺序,但无法找出如何使其工作。

这是一种处理密码访问的奇怪方式。首先,您永远不应该将密码数据发送回用户,即使有些加密。我建议你开个会。调用
session_start()在验证部分开始之前。在密码验证部分,当登录正确时,您可以将用户名写入会话,如
$\u session['login']=$login
这也使得登录用户的验证更容易,比如
如果(array_key_存在('login',$_SESSION)){echo“我是一个登录用户!”}或者{echo“请立即登录!”}
。正如您可能看到的,更少的代码和更安全的方式。此外,您的SQL目前什么也不做,因为所有电子邮件地址都会相互覆盖,结果甚至不会被使用。您也应该关闭连接,而不仅仅是
die()
