最佳实践

1. 使用 Hooks 和 Filters

在不编辑核心文件的情况下扩展 WordPress 功能:

// User registration
add_filter('wp_pre_insert_user_data', 'verify_user_email');

// Comment submission
add_filter('preprocess_comment', 'verify_comment_email');

// Contact form
add_filter('wpcf7_validate_email', 'verify_contact_email');

2. 缓存验证结果

将结果存储在 WordPress options 或 transients 中:

function verify_email_with_cache($email) {
  $cache_key = 'email_verify_' . md5($email);
  $cached = get_transient($cache_key);

  if ($cached) {
    return $cached;
  }

  $result = emailverify_verify($email);
  set_transient($cache_key, $result, DAY_IN_SECONDS);

  return $result;
}

3. 优雅地处理错误

如果验证服务不可用,允许注册:

try {
  $result = verify_email($email);
} catch (Exception $e) {
  // Log error but don't block registration
  error_log('Email verification failed: ' . $e->getMessage());
  // Continue with registration
}

4. 向用户提供反馈

为用户提供关于邮箱有效性的清晰消息:

if ($verification['status'] === 'invalid') {
  wp_die('Please enter a valid email address');
} elseif ($verification['result']['disposable']) {
  // Warning but allow continuation
  $warning = 'This email appears to be temporary';
}

5. 监控和记录

跟踪邮箱验证以进行质量保证:

// Log verification results
error_log(json_encode([
  'email' => $email,
  'status' => $result['status'],
  'score' => $result['score'],
  'timestamp' => current_time('mysql')
]));

常见 WordPress 场景

场景 1: 仅验证注册

仅在用户注册期间验证邮箱,而非配置文件更新:

add_filter('registration_errors', function($errors, $login, $email) {
  if (!isset($_POST['user_login'])) {
    // Only during registration, not admin updates
    $result = verify_email($email);
    if ($result['status'] === 'invalid') {
      $errors->add('invalid_email', 'Invalid email address');
    }
  }
  return $errors;
}, 10, 3);

场景 2: 软验证

警告用户有风险的邮箱但不阻止:

$result = verify_email($email);

switch ($result['status']) {
  case 'invalid':
    $this->add_warning('This email appears invalid. Please double-check.');
    break;
  case 'unknown':
    $this->add_notice('We couldn\'t verify this email.');
    break;
}
// Allow registration to proceed

场景 3: 管理员审核

标记可疑邮箱供管理员审核:

if ($result['status'] === 'unknown' || $result['result']['disposable']) {
  // Create user but mark for review
  $user = wp_insert_user($user_data);

  // Add admin note
  add_post_meta(
    $user->ID,
    '_email_verification_flag',
    $result,
    true
  );

  // Notify admin
  wp_mail(
    get_option('admin_email'),
    'New user requires review: ' . $email,
    'Email verification result: ' . json_encode($result)
  );
}
