$_SESSION doesn't start
Question
When user is logged in nothing is displayed on the screen(Error-reporting is on).
It's like the $_SESSION is not true?
<?php
include_once('../includes/connection.php');
if (isset($_SESSION['logged_in'])) {
?>
<html>
<head>
<title>wa</title>
<link rel="stylesheet" type="text/css" href="../assets/stylesheet.css">
</head>
<body>
<div class="container">
<a href="index.php" id="logo">CMS</a>
<br />
<ol>
<li><a href="add.php">Add Article</a></li>
<li><a href="delete.php">Delete Article</a></li>
<li><a href="logout.php">Logout</a></li>
</ol>
</div>
</body>
</html>
<?php
} else {
if (isset($_POST['username'], $_POST['password'])) {
$username = $_POST['username'];
$password = md5($_POST['password']);
if (empty($username) or empty($password)) {
$error = 'All fields are required!';
}else {
$query = $pdo->prepare("SELECT * FROM users WHERE user_name = ? AND user_password =
?");
$query->bindValue(1, $username);
$query->bindValue(2, $password);
$query->execute();
$num = $query->rowCount();
if ($num == 1) {
$_SESSION['logged_in'] = true;
header('Location: index.php');
exit();
} else{
$error = 'Incorrect details!';
}
}
}
?>

You need to call session_start(); at the beginning of your PHP file. If you have multiple files then adding it once to your connection file will work for all of them.

At line 39 md5$_POST['password']); you missed "("
md5($_POST['password']);

Every php file which has $_SESSION variable needs to include session_start(); on the top of the page.
When page gets a white screen after loading, you should see php_error_log for possible syntax errors (could be missing ";"). Please, review your code. Hope it helps you.
