PHP登录和会话 [英] PHP Login and session
问题描述
早上好，晚上
我被困住了，我需要PHP方面的帮助.
I'm stuck and I need some help in PHP.
我正在尝试编写一个管理仪表板.而且我想检查用户是否已登录，如果没有，请重定向到登录页面.
I am trying to code up an admin dashboard. And I want to check if user is logged in, if not , redirect to the login page.
我的index.php是这样的:
My index.php is this:
<?php
$pagename ="Index";
@require_once('inc/head.php');
?>
<body>
CONGRATS! Welcome to the Admin dashboard.
</body>
</html>
我的登录页面:
<?php
$pagename = "login";
$adminUser = "admin";
$adminPass = "admin";
@require_once('inc/head.php');
// If POST is submitted and IDs match the ones set
if($_SERVER["REQUEST_METHOD"] == "POST")
{
if($_POST["username"] == $adminUser && $_POST["password"] == $adminPass)
{
session_start();
$_SESSION["username"] = $adminUser;
$_SESSION["login"] = true;
echo '<script>alert("Congrats, you logged in");
window.location = "index.php"; </script>';
/* I skip the line underneath because for unknown reasons my code
Doesn't fully run through. So I redirected with the JS above instead.
header("Location: index.php");
exit(); */
}else{
echo '<script>alert("Incorrect username or password!'");</script>';
}
}
?>
<html>
<!-- login page here -->
</html>
这是我的head.php:
And here goes my head.php:
<?php
// If we AREN'T on the login page , check if session exist. If not send to login
if($pagename != "login")
{ if(!$_SESSION['login'])
{
header('location: login.php');
exit();
}
}
?>
这有很多问题，我知道，但到目前为止，我正在尝试解决我的登录问题.每当我登录时，都会弹出JS窗口，提示我已成功登录，但是我没有重定向到索引.我认为我确实发送到了index.php(没有理由将我的JS重定向到NOT函数)，但是我的索引使我立即回到登录状态，而我不明白为什么.
There is alot of things wrong with this and I know but as of now I'm trying to fix my login in issue. Whenever I log in I get the JS pop up that says I successfully logged in, but I don't get redirected to the index. I think I do get sent to my index.php ( there's no reason for my JS redirect to NOT function ) but my index sends me right back to login and I don't understand why.
推荐答案
head.php 页面中的启动会话.
head.php
<?php
if($pagename != "login") {
session_start();
if(!$_SESSION['login']) {
header('location: login.php');
exit();
}
}
?>
