session_start();

// Check if user is already logged in
if(isset($_SESSION['user_id'])) {
    header("Location: dashboard.php"); // Redirect to dashboard if already logged in
    exit();
}

// Include database connection
require_once 'db_connection.php';

// Process login form submission
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Query database to check credentials
    $stmt = $conn->prepare("SELECT * FROM users WHERE username = ?");
    $stmt->execute([$username]);
    $user = $stmt->fetch(PDO::FETCH_ASSOC);

    // Verify password
    if($user && password_verify($password, $user['password'])) {
        // Password correct, set session variables
        $_SESSION['user_id'] = $user['id'];
        $_SESSION['username'] = $user['username'];
        
        // Redirect to dashboard or desired page
        header("Location: dashboard.php");
        exit();
    } else {
        // Invalid credentials
        $error = "Invalid username or password.";
    }
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="login-container">
        <h2>Login to Your Account</h2>
        <?php if(isset($error)) { ?>
            <p class="error"><?php echo $error; ?></p>
        <?php } ?>
        <form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
            <label for="username">Username:</label>
            <input type="text" id="username" name="username" required>
