I'm doing a database project for university and I'm strugling with a problem in here. I'm trying to show "log in" when there's no session and "log out" when there is a session. But actually even after I log in it still shows me "log in" and I tried to print_r($_SESSION); and it tells me that the variable is undefined
I have a logout file:
<?php
session_start();
session_destroy();
header("Location:index.php");
?>
and a init.php file:
<?php
session_start();
?>
init.php is called when I log in.
Here is a part of index.php:
<?php
require 'db/connect.php';
require 'functions/security.php';
?>
<html>
<head>
<title>Home</title>
<meta charset="UTF-8">
<link rel="stylesheet" href="css/common.css">
</head>
<body>
<div id="linking">
<?php
//print_r($_SESSION);
if (session_status() === PHP_SESSION_NONE) {
?>
<a href="login.php">Log In</a>
<?php
} else {
?>
<a href="logout.php">Log Out</a>
<?php
}
?>
<a href="new_customer.php">Register</a>
<a href="trips.php">Search for trips</a>
</div>
<hr>
<section id="section">
636
when your login is success on login page.
session_start();
$_SESSION['user_logged_in'] = true;
in your logout page
session_start();
unset($_SESSION['user_logged_in']);
session_destroy();
in your home page
<?php
session_start();
if(isset($_SESSION['user_logged_in'])) {
?>
< a href='logout.php'>Logout</a>
<?php
}
else {
?>
< a href='login.php'>Login</a>
<?php
}
?>
