Feature: Lesson Booking

Overview

Students register for a private lesson by choosing an offering, picking a time (or reserving a weekly slot for the term), answering the offering's intake questions, accepting current policies, and paying. Instructors confirm or cancel from wp-admin or via the REST API. A lesson becomes confirmed only once its payment is paid (or the student is comp'd).

Registration Flow

1. Student opens the page with the [us_booking] shortcode and browses open slots as a weekly calendar (the default, anchored to the week of the earliest open slot) or an agenda list (view toggle with previous/next-week navigation; times shown in 12-hour AM/PM form).
2. Student picks a slot and an offering (a 30 or 60-minute private-lesson type). When the slot is tied to an offering the form shows it locked (the student sees exactly what they are booking); otherwise the form presents the instructor's active private-lesson offerings whose duration fits the slot. Every booking requires an offering — a generic slot with no fitting offering cannot be booked online.
3. For a weekly reservation, the same weekday/time is held for the rest of the offering's term.
4. Student answers the offering's questions (GET /offerings/{id}/questions).
5. Student accepts the current published policy versions (GET /policies) — required to continue.
6. Payment is taken per the student's billing method (card by default; pending for e-transfer; skipped for comp). See payments.md.
7. POST /bookings creates the lesson row(s) (status = pending), records answers and policy acceptances, marks us_availability.is_booked = 1, and links the payment. A booking with nothing owed (a free offering) creates no payment and is confirmed immediately.
8. On successful payment (or comp) the lesson is confirmed and a receipt is emailed.
9. Instructor sees the booking under My Lessons and may update status via PATCH /bookings/{id}/status.
10. The booking page also shows the student their upcoming lessons (GET /bookings) with a per-lesson status badge (pending payment / confirmed) and a Cancel button.

Cancellation

Students cancel their own lessons via POST /bookings/{id}/cancel (idempotent). Cancelling marks the lesson cancelled, frees the availability slot for rebooking, and voids a still-pending payment (marked failed so it leaves the admin confirmation queue). A paid payment is never touched — refunds are a manual, admin-side decision. Instructors cancelling via PATCH /bookings/{id}/status get the same slot release and payment voiding; reinstating a cancelled lesson re-claims its slot and fails with 409 slot_taken if the freed time was booked by someone else in the meantime.

Weekly Reservations

A weekly reservation creates one series_id shared across N lesson rows (one per week in the term) and reserves the matching availability windows. It is billed full-term upfront as a single payment (billing_mode = full_term on the offering).

REST API

Method	Endpoint	Permission
GET	/wp-json/us-scheduler/v1/bookings	Any logged-in user
POST	/wp-json/us-scheduler/v1/bookings	book_lesson
POST	/wp-json/us-scheduler/v1/bookings/{id}/cancel	Logged-in owner of the lesson
PATCH	/wp-json/us-scheduler/v1/bookings/{id}/status	manage_availability or admin

POST /bookings body: offering_id, slot_id, recurrence, answers[] (question_id → value), accepted_policy_version_ids[], and payment data (see payments.md). The response includes ids, the resulting lesson status, and payment — a {id, method, status} summary, or null when nothing is owed (the front end then skips the payment step).

An offering is always required (400 offering_required otherwise): a slot tied to an offering uses that offering regardless of the request, while a generic slot uses the student's offering_id, which must be one of the instructor's active private_lesson offerings whose duration_minutes matches the slot.

GET /bookings returns the caller's upcoming, non-cancelled lessons (their own for students; the instructor's for callers with manage_availability), each with the slot's start_dt/end_dt.

Group classes follow the same registration flow but enrol against an offering of kind group_class; see group-classes.md.

Admin Interface

• Scheduler (view_all_lessons — studio admin / administrators): all upcoming lessons across all instructors
• My Lessons (view_own_lessons): upcoming lessons for the logged-in instructor

Both pages open in a Week calendar view by default (usc_view/usc_week query params, same pattern as the availability page, bucketed via Availability\WeekCalendar), with the original table available as the List view — the list is where the per-lesson HST and e-transfer edit forms live.

Frontend Shortcodes

• [us_booking] — student calendar + registration flow; requires book_lesson capability
• [us_student_login] — front-end login form for students

Implementation

• Repository: Unsupervised\Schedular\Booking\BookingRepository (insertSeries() builds a weekly series sharing a series_id)
• Model: Unsupervised\Schedular\Booking\Lesson
• Registration gate: Unsupervised\Schedular\Registration\RegistrationGate — validates and records intake answers + booking-scoped policy acceptances; shared with group enrolment
• Admin controller: Unsupervised\Schedular\Booking\LessonController
• REST endpoint: Unsupervised\Schedular\Booking\BookingEndpoint
• Frontend: Unsupervised\Schedular\Booking\BookingPage, Unsupervised\Schedular\Auth\LoginPage

Payment seam: a priced booking is created with status = pending and its payment linked via payment_id; the lesson is confirmed when the payment is settled (see payments.md) or manually via PATCH /bookings/{id}/status. Unpriced bookings skip the seam entirely and are confirmed at creation. GET /policies?scope=booking returns just the booking-gate policies the form must collect.
