Izurutoys Confirmation Screen for Contact Form 7

Izurutoys Confirmation Screen for Contact Form 7 adds a confirmation step (“kakunin gamen”) to Contact Form 7 forms — a de-facto requirement for Japanese business websites.

Contact Form 7 のフォームに「送信前の確認画面」を追加するプラグインです。

Add the buttons to your form template — that is all:

[confirm "入力内容を確認する"]
[back "戻って編集する"]
[submit "この内容で送信する"]

• The confirm button runs Contact Form 7’s own full server-side validation (mail is not sent yet).
• On success the form switches to a read-only confirmation view with Back / Send buttons.
• The send button performs the normal Contact Form 7 submission.
• If JavaScript is disabled, the form gracefully degrades to a normal one-step form.

Migrating from “Contact Form 7 add confirm”

This plugin is a from-scratch successor to “Contact Form 7 add confirm” (by Yuichiro ABE / Eyeta Co.,Ltd.), which has not been updated since February 2018 and no longer works with current Contact Form 7 (5.4+ replaced the submission flow with a REST endpoint).

「Contact Form 7 add confirm」からの乗り換え先として、フォーム定義を変えずに使えるように作られています。

• Same form-tag syntax: existing [confirm “…”] / [back “…”] form definitions work unchanged.
• Same public CSS class names (wpcf7c-btn-confirm, wpcf7c-conf, …): custom styles for the old plugin keep working.
• Migration is two steps: deactivate the old plugin, activate this one. No form editing needed.

Technical notes

• Works with the Contact Form 7 REST submission flow.
• No jQuery dependency (vanilla JavaScript).
• The duplicate-submission guard (posted_data_hash) is handled correctly at the confirmation step.
• Side effects apply only to forms that actually contain a [confirm] tag.
• Flamingo: records are stored only on the final send (not on the confirmation step).
• Covered by end-to-end tests (Playwright against a live WordPress + Contact Form 7).
