- Add required email input (with autocomplete="email") to the booking
details form in the homepage Preact widget (rpt-booking.js).
Update EMPTY_FORM, submit payload, confirmedAppointment, and success
summary to include it. The form now collects: first/last name, email,
phone, comments.
- Update ScheduleController::storeSlot to extract/pass email in the
booking_request mail params (and require it for the full-contact path).
Log failures with details; return a structured error with a user-friendly
message instead of bare "mail_failed".
- riverside_pt_mail hook now includes the user's email in the notification
body (when provided).
- Dev improvements for mail:
- In DEBUG mode (default on localhost), force php_mail interface in
settings.php so the mailer uses the sendmail_path override.
- Dockerfile + entrypoint.sh now provide/install a fake-sendmail.sh
that prints the full email (To, Subject, headers, body from the
hook) to stderr (visible in `docker compose logs`) and always
succeeds (exit 0). This prevents "sh: 1: /usr/sbin/sendmail: not
found" and guarantees booking submissions never return the
"unable to send confirmation email" error in dev.
- In non-DEBUG, still uses symfony_mailer + Postmark as before.
- The fake is also baked into the image for consistency.
- JS error handling now prefers the server-provided 'message' from
the JSON error response (better UX for real mail failures).
- Update CLAUDE.md with the new email field + dev mail mocking behavior.
- New file: docker/php/fake-sendmail.sh (the mock).
This addresses the recent "mail_failed" issues while keeping production
email via Postmark.
