Описание
Selective reCAPTCHA Loader for CF7 is a performance optimization plugin that intelligently controls when and where Google reCAPTCHA assets are loaded for Contact Form 7 forms. Instead of loading reCAPTCHA on every page, this plugin provides two modes to optimize your site’s performance.
Key Features
🚀 Two Loading Modes:
— Selective Mode (Default): Only loads reCAPTCHA on pages that contain Contact Form 7 forms
— Global Mode: Always loads reCAPTCHA on all front-end pages (traditional behavior)
🎯 Smart Detection:
— Detects CF7 shortcodes in post content
— Identifies CF7 blocks in Gutenberg editor
— Whitelist-based override for specific pages
⚙️ Advanced Configuration:
— Whitelist specific pages by ID, slug, or regex patterns (pages matching the whitelist will always load reCAPTCHA)
— Comprehensive filter system for developers
How It Works
The plugin hooks into WordPress’s script enqueuing system with a priority of 120, analyzing each page to determine if Contact Form 7 forms are present. Based on your selected mode and detection results, it either allows or prevents reCAPTCHA assets from loading.
Caching Considerations:
— Per-page detection results are cached per request
— Cache automatically clears when plugin settings change
Developer Features
Filters:
— selerelo_is_form_page — Modify form page detection
— selerelo_recaptcha_handles — Define which script handles to control
Template Functions:
— selerelo_should_load_recaptcha() — Check if reCAPTCHA will load
— selerelo_is_form_page() — Check if page has forms
— selerelo_get_option() — Get plugin options
Technical Details
Minimum Requirements:
— WordPress 6.0 or higher
— PHP 7.4 or higher
— Contact Form 7 5.8 or higher
Performance Impact:
— Minimal overhead: Detection logic is lightweight and cached
— Reduces script loading on pages without forms
— Can significantly improve page load times on form-free pages
Security:
— All user inputs are sanitized and escaped
— Uses WordPress nonces for form submissions
— Follows WordPress coding standards
— No external API calls or tracking
日本語版説明
Selective reCAPTCHA Loader for CF7 は、Contact Form 7 のパフォーマンスを最適化するプラグインです。全ページでreCAPTCHAを読み込む代わりに、フォームがあるページでのみ読み込みます。
主な特徴
2つの読み込みモード:
— Selectiveモード(推奨): フォームがあるページのみ読み込み
— Globalモード: 全ページでreCAPTCHA読み込み(従来方式)
スマート検出:
— ショートコード、Gutenbergブロック内のフォームを検出
— ホワイトリスト機能(ページID、スラッグ、正規表現対応、ホワイトリストに一致したページは必ずreCAPTCHAを読み込みます)
インストール
- プラグインファイルを
/wp-content/plugins/selective-recaptcha-loader/にアップロード - 管理画面の「プラグイン」でプラグインを有効化
- 「設定」「Selective reCAPTCHA」で設定
- Selectiveモードのまま使用を推奨(ほとんどのサイトに最適)
使い方
Globalモード: 全ページでreCAPTCHAを読み込みます。サイト全体にフォームがある場合に適しています。
Selectiveモード: フォーム検出したページのみreCAPTCHAを読み込みます。最大のパフォーマンス向上が期待できます。
注意事項
キャッシュプラグイン:
ほとんどのキャッシュプラグインと互換性があります。検出ロジックはキャッシュ前に実行されます。
Установка

Часто задаваемые вопросы
-
Does this plugin work without Contact Form 7?
-
No, this plugin requires Contact Form 7 to be active. It will gracefully deactivate functionality if CF7 is not detected.
-
Can I force reCAPTCHA to load on specific pages?
-
Yes! Add pages to the whitelist in settings using:
— Post ID (e.g., 123)
— Page slug (e.g., contact)
— Regular expression (e.g., /^https:\/\/example.com\/custom/)
You can also use theselerelo_is_form_pagefilter for custom logic. -
Is this plugin compatible with caching plugins?
-
Yes, the plugin is designed to work with caching plugins. The detection logic runs before caching occurs and uses WordPress transients for performance.
