Not every open time can be booked as every private-lesson type: a slot tied to an offering takes that offering only, and a generic slot only takes types whose length fits. Students had no way to see that before clicking a time. The booking calendar now carries a lesson-type filter — a checkbox per active private-lesson type, fetched once from GET /offerings?kind=private_lesson. Ticking types narrows the calendar to the times bookable as one of them and re-anchors the week view on the earliest match. The registration form's Lesson type picker is narrowed the same way, and a lone remaining type is pre-selected with its intake questions loaded. Bookability is decided by offeringFitsSlot(), the client-side mirror of the rule POST /bookings enforces; the filter is a browsing aid and the server still validates every booking. No ticks means no filter, and the whole control is hidden when the studio offers fewer than two private-lesson types. Closes #117 Co-Authored-By: Claude Opus 5 <[email protected]>

Feature: Availability Management
Overview
Instructors define same-day date/time windows during which they are available for private lessons. On save, a window is split into consecutive lesson-length slots (09:00–16:00 with 60-minute lessons becomes seven rows), each independently bookable by students. Windows may be generated as a weekly-recurring series.
Data Model — {prefix}us_availability
| Column | Type | Notes |
|---|---|---|
id |
BIGINT UNSIGNED | Primary key |
instructor_id |
BIGINT UNSIGNED | WordPress user ID |
offering_id |
BIGINT UNSIGNED | Nullable FK → us_offerings.id (private-lesson type) |
start_dt |
DATETIME | Slot start — stored as Y-m-d H:i:s |
end_dt |
DATETIME | Slot end — always start_dt + duration_minutes |
duration_minutes |
SMALLINT | Lesson length (e.g. 30, 60) |
is_booked |
TINYINT(1) | 0 = available, 1 = booked |
recurrence_group |
BIGINT UNSIGNED | Nullable — weekly-recurring windows share one group id |
created_at |
DATETIME | Insertion time |
A slot's duration_minutes is matched against the offering a student picks: a
30-minute private offering can only be booked into a slot whose
duration_minutes accommodates it.
Window Splitting
AvailabilitySlot::splitByDuration() chunks a submitted window into consecutive
duration_minutes slots; AvailabilityRepository::createFromWindow() persists
one row per chunk. A trailing remainder shorter than the lesson length is
dropped. Windows must start and end on the same day and fit at least one lesson
(REST responds 400 invalid_window otherwise; the admin form is a no-op).
AvailabilityRepository::splitOversizedWindows() is a data migration (run by
Installer on activation or version change) that rewrites pre-split rows.
Weekly-Recurring Windows
Instructors may generate a window weekly across a date range. Each lesson-length
chunk becomes its own weekly series: occurrences of the same time-of-day share
one recurrence_group id, so a recurring set can be added or removed together
while individual occurrences are still booked independently.
Admin Interface
Instructors access My Availability in wp-admin (?page=us-availability).
- Add availability: provide a same-day start/end window, lesson length, and (optionally) a linked private-lesson offering
- Add a weekly series: tick weekly repeat and choose the number of weeks
- Delete a slot: only allowed if
is_booked = 0 - Bulk delete: the list view has a checkbox per unbooked slot (with a select-all header checkbox) and a Delete selected button (
usc_action=bulk_delete,slot_ids[]); each id is ownership-checked, and booked slots are refused at the repository level - Current slots can be shown as a weekly calendar (the default, navigated with
usc_week=Y-m-d) or a list (usc_view=list); the grid honours the site'sstart_of_weekoption viaAvailability\WeekCalendar
Public Calendar
The front-end booking shortcode renders open slots from GET /availability
either as an agenda-style list grouped by day or as a weekly calendar with
previous/next-week navigation (toggle rendered by assets/js/booking.js; the
site's start_of_week option is passed through the usScheduler JS config).
Both views can be narrowed to the slots bookable as chosen private-lesson types
with the lesson-type filter — see lesson-booking.md.
REST API
| Method | Endpoint | Permission |
|---|---|---|
GET |
/wp-json/us-scheduler/v1/availability |
book_lesson |
POST |
/wp-json/us-scheduler/v1/availability |
manage_availability |
DELETE |
/wp-json/us-scheduler/v1/availability/{id} |
manage_availability + slot owner |
GET supports query params: instructor_id, offering_id, duration_minutes, from (datetime), to (datetime).
Slots whose start has already passed are never returned.
POST validates start_dt/end_dt (admin form and REST alike) via
AvailabilitySlot::normalizeDateTime(): the canonical Y-m-d H:i[:s] and HTML
datetime-local (Y-m-d\TH:i[:s]) forms are normalised to Y-m-d H:i:s;
anything else — or an end not after the start — is rejected (REST responds
400 invalid_datetime; the admin form is a no-op). A valid window is stored as
lesson-length slots and 201 returns { "ids": [...] } for every row created.
Times are displayed in 12-hour AM/PM form in the booking calendar and wp-admin lists.
