PHP登录身份验证不起作用 [英] PHP login authentication not working
问题描述
我有两个.php文件。所有的HTML和PHP，没有SQL，不会需要/使用它。一个是登录页面，另一个是目的地。当我在日志中记录我设置的详细信息时，我无法到达目的地。如您所见， session_start（）; 显然位于顶部。我甚至把它放在与开放的php标签相同的行上，没有任何区别。以下是这两个页面的代码：
I have two .php files. All html and php, no SQL and will not be needing/using it. One is the login page, the other is the destination. When I put in the log in details I have set, I can't get to the destination. As you can see, session_start(); is clearly at the top. I even put it right on the same line as the opening php tag and no difference was made. Here's the code for both pages:
登录：
<?php
session_start();
$username="testu";
$password="testp";
$_SESSION['logged_in']=false;
if (isset($_SESSION['logged_in']) && $_SESSION['logged_in'] == true) {
header("Location: dest.php");
exit;
}
if (isset($_POST['user']) && isset($_POST['pass'])) {
if ($_POST['user'] == $username && $_POST['pass'] == $password) {
$_SESSION['logged_in'] = true;
header("Location: dest.php");
exit;
}
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<title>A title</title>
</head>
<body>
<form action="dest.php" method="post" style="font- family:calibri;position:absolute;top:40%;left:35%;">
Username: <input type="text" name="user"/><br><br>
Password: <input type="password" name="pass" style="position:relative;left:5px;"/><br><br><br>
<input type="submit" value="Submit" style="position:relative;left:115px;"/>
</form>
</body>
</html>
目的地：
(php tag here)
session_start();
if (!isset($_SESSION['logged_in']) || $_SESSION['logged_in'] == false) {
header("Location: login.php");
exit;
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<title>A title</title>
</head>
<body>
<a href="login.php">Log out</a>
</body>
</html>
我注意到当我在目标文件上注释掉php代码时，我可以访问dest。 PHP。问题是，我可以访问任何登录详细信息，或者根本没有。它要么无效，要么有效。我怎样才能获得我已经开始工作的细节？我觉得这个问题在登录页面脚本中。非常感谢任何能够帮助我解决这个问题的人。
I noticed that when I commented out the php code on the destination file, I could access the dest.php. Issue is, I could access is with any login details, or none at all. It's either nothing works, or anything works. How can I get the details I have set to work? I feel the issue is in the login page script. Many thanks in advance to anyone who can help me resolve this.
注意：我不得不重新发布这个，因为我最后一个问题被标记为与我完全无关的事情的副本问题，谢谢。
Note: I had to repost this because my last question was marked as a duplicate of something completely irrelevant to my issue, thank you.
推荐答案
@Sean打败我，好工作： - ）
如果您删除 action =dest.php，它应该可以工作。现在您将表单发送到不检查用户名和密码值的页面，因此未设置会话变量。
If you remove the action="dest.php" it should work. Right now you are sending the form to a page that does not check the values of the username and password, thus the session variable is not set.
<form method="post">
Username: <input type="text" name="user"/>
....
</form>
