RIS Cloudflare CAPTCHA – Cloudflare Turnstile

描述

RIS Cloudflare CAPTCHA adds the modern, privacy-first Cloudflare Turnstile CAPTCHA to your WordPress site. Stop bots, spam comments, and brute-force login attacks without annoying your visitors with image puzzles or Google reCAPTCHA.

Unlike legacy CAPTCHAs, Cloudflare Turnstile runs completely in the background, never asks visitors to click traffic lights or type distorted text, and protects visitor privacy.

Why Choose RIS Cloudflare CAPTCHA?

• Privacy-friendly – No user tracking, no cookies, no personal data collection.
• User-friendly – Most visitors never see a challenge; it’s invisible by default.
• Lightweight – Tiny footprint, no external dependencies, no bloated JS bundles.
• Free – Powered by Cloudflare Turnstile, which is 100% free for unlimited use.
• Universal – Protects WordPress login, registration, comment, lost-password, and WPForms.
• Developer-friendly – Shortcode, PHP function, and a verification filter for custom forms.
• Multilingual – Supports 11 widget languages including English, Spanish, French, German, Bengali, Hindi, Arabic, Chinese, Japanese, and more.
• Customizable – Light, dark, or auto theme; visible, invisible, or interaction-only mode.

Features

  • WordPress login form
  • WordPress registration form
  • WordPress lost password form
  • WordPress comment form

• Developer filter: ris_cf_captcha_verify_response for custom verification.

Or in PHP:

Custom Form Verification (Developers)

Hook into the verification filter:

add_filter( 'ris_cf_captcha_verify_response', function( $is_valid, $token, $ip ) {
 // Your custom checks here.
 return $is_valid;
}, 10, 3 );

Privacy

This plugin:
* Does not set any cookies.
* Does not track users.
* Does not store any personal data.
* Sends the visitor’s IP address to Cloudflare only for the verification request, as required by the Turnstile API.
* Does not send any data to any third party other than Cloudflare.
