## 外掛說明

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.

## 安裝方式

 1. Activate the plugin.

 4. Add the contact form block to a page, or insert the shortcode [cuerda_email_form].

## 常見問題集

### Are inquiry contents stored in WordPress?

No. The plugin does not store inquiry contents in the WordPress database. To prevent
duplicate submissions, it temporarily stores only non-personal submission state 
and temporary processing state.

### Can I cache the page containing the contact form?

The contact form page handles temporary state during confirmation and submission,
so it should be excluded from page caching. The plugin also sends no-cache headers
for pages containing the form, but settings in caching products may take precedence.

### How are PDF attachments handled?

One PDF file can be attached, up to 5 MB or the lower upload limit provided by the
WordPress server environment. The PDF is attached to the administrator notification
but is not attached to the automatic reply.

PDF files are not registered in the WordPress Media Library, and neither the inquiry
body nor the PDF itself is stored in the WordPress database. Before sending, the
PDF is held only in a private temporary area and is deleted after a successful submission.
Abandoned temporary files are cleaned up after 24 hours.

If a safe temporary area cannot be used, or if file uploads are unavailable in the
server environment, PDF attachments are disabled. The contact form can still be 
used without a PDF attachment.
