    </form>
</body>
</html>

Validation

// 1. VERIFY - default
$validation = $captcha->server->verify("login-action");

// 1. VERIFY - manual token data
$token = $_POST['captcha-token'];
$validation = $captcha->server->verify("login-action", $token);

// 1. VERIFY - manual token data + IP verification
$ip = $_SERVER['HTTP_CLIENT_IP'] ?? $_SERVER['REMOTE_ADDR'] ?? null;
$token = $_POST['captcha-token'];
$validation = $captcha->server->verify("login-action", $token, $ip);

// 2. CHECK VALIDATION
if(!$validation->isSuccess){
    $messageError = $validation->errorMessage;
    $arrayErrors = $validation->errors;
    // show error
}
