所以我从 php 开始,我有一个非常简单的设置。我有 2 页。一个页面是登录页面,另一个是登录页面。我现在的问题是每当我成功登录时,第二页仍然认为我没有登录。这是我的代码:
我知道我登录正确,因为它没有打印“错误”,并且在进入下一页之前我看到了“到这里”打印。登录页面:
<!DOCTYPE html>
<html>
<head>
<?php
session_start();
?>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">
<?php
if (isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true) {
?>
<script language="Javascript"> window.location.href="show.php";</script>
<?php
}?>
</head>
<body>
<form method="post">
Username: <input type="text" name="username" size="15" /><br />
Password: <input type="password" name="pass" size="15" /><br />
<input type="submit" name ="submit1" value="Login"/>
</form>
<?php
if (isset($_POST['submit1'])) {
if (LOGGEDIN) {
print "GOT HERE";
$_SESSION['loggedin'] = true;
$_SESSION['user'] = $username;
?>
<script language="Javascript"> window.location.href="show.php";</script>
<?php
}
else {
print "WRONG!";
}
}
?>
</body>
</html>
登录页面:
<!DOCTYPE html>
<html>
<head>
<?php session_start();?>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">
<?php
if (!isset($_SESSION['loggedin']) || $_SESSION['loggedin'] == false) {
?>
<script language="Javascript"> window.location.href="index.php";</script>
<?php
}?>
</head>
<body>WELCOME
</body>
</html>
