        // Redirect on success
        header("Location: thank_you.html");
    } else {
        // Error handling
        http_response_code(500);
        echo "Oops! Something went wrong.";}
    } else {
    // Handle incorrect request method
    http_response_code(403);
    echo "There was a problem with your submission, please try again.";
