原文外掛簡介
Cuerda Email Form is a contact form developed for Japanese websites with a focus on security and simple installation.
It is designed to let web designers, production staff, blog editors, and administrators of small websites add a general-purpose contact form without complicated setup.
The form provides four fields: Name, Subject, Email Address, and Message. Visitors can review their entries on a confirmation screen before sending. The plugin provides administrator notifications, automatic replies, protection against automated spam and duplicate submissions, and one optional PDF attachment. The PDF size limit is up to 5 MB and may be lower depending on the WordPress server environment.
Cloudflare Turnstile can optionally be used for spam protection. Cloudflare Turnstile is an alternative to CAPTCHA that can verify visitors with less user interaction.
Advanced users can apply additional CSS to the form from the WordPress administration screen. Inquiry contents are not stored in the WordPress database.
External services
Cloudflare Turnstile is an optional feature that can reduce automated spam submissions. It is used only when a site administrator enables it in the plugin settings. A Cloudflare Turnstile Site Key and Secret Key are required to use this feature.
When Turnstile is enabled, the visitor’s browser loads Cloudflare’s official Turnstile runtime on the confirmation and submission screen:
https://challenges.cloudflare.com/turnstile/v0/api.js
When the form is submitted, the plugin’s server-side code sends a verification request to Cloudflare’s siteverify API:
https://challenges.cloudflare.com/turnstile/v0/siteverify
The siteverify request contains the Cloudflare Secret Key, the Turnstile response token received from the visitor, and a submission identifier used as the idempotency key to prevent duplicate verification. No inquiry form fields are sent to siteverify.
When Turnstile is disabled, the browser does not load the Turnstile runtime and the plugin does not send siteverify requests to Cloudflare.
