原文外掛簡介
This plugin adds Cloudflare Turnstile — a free, privacy-friendly CAPTCHA alternative — to your WordPress site.
Its key difference from other Turnstile plugins is per-form control for Elementor Pro: instead of toggling Turnstile globally for every Elementor form, you add a “Cloudflare Turnstile” field to the specific forms you want to protect, exactly like Elementor’s built-in reCAPTCHA field. Forms without the field are left untouched. If you prefer the all-at-once approach, an optional setting protects every Elementor Pro form automatically.
Features
Per-form Turnstile field for Elementor Pro Forms — drag it into the forms you choose.
Optional “all Elementor Pro forms” switch — protect every Elementor Pro form at once, without adding the field to each one (off by default).
Optional protection for the built-in WordPress forms:
Login
Registration
Lost password
Comments
One-click import of keys and settings from the “Simple Cloudflare Turnstile” plugin (no need to recreate your Cloudflare keys).
Global widget appearance settings (theme, size, visibility, language).
Strict server-side token verification (single-use tokens, 5-minute validity).
Secure-by-default behaviour: missing/invalid tokens are always blocked; the
behaviour when Cloudflare itself is unreachable is configurable.
Write-only secret key (never displayed or sent to the browser).
Lightweight: in the default per-form mode, the Cloudflare script loads only on pages that actually show a widget. (The optional “all forms” mode loads it across the front end so late-loaded forms are covered.)
Requirements
The Elementor field requires Elementor Pro (the Forms widget is a Pro feature). Without Elementor Pro, the WordPress form integrations still work.
A free Cloudflare Turnstile site key and secret key.
Third-party service
This plugin renders the official Cloudflare Turnstile widget and verifies tokens with Cloudflare.
When a protected form is displayed, the visitor’s browser loads https://challenges.cloudflare.com/turnstile/v0/api.js from Cloudflare.
When a protected form is submitted, your server sends a request to https://challenges.cloudflare.com/turnstile/v0/siteverify containing: the Turnstile token from the widget (cf-turnstile-response), your secret key, and — unless disabled with the cwebts_remoteip filter — the visitor’s IP address (REMOTE_ADDR). The secret key is never sent to the browser.
