Editor Blocks

Gutenberg dynamic-block wrappers for the plugin's four front-end shortcodes, so the pages can be previewed and styled inside the block editor instead of appearing as grey shortcode text.

Blocks

Block	Wraps shortcode	Front-end renderer
us-scheduler/booking	[us_booking]	Booking\BookingPage::render()
us-scheduler/student-login	[us_student_login]	Auth\LoginPage::render()
us-scheduler/student-register	[us_student_register]	Auth\RegistrationPage::render()
us-scheduler/group-classes	[us_group_classes]	GroupClass\GroupClassPage::render()

The shortcodes remain registered for back-compat; blocks and shortcodes share the same page objects (constructed once in Plugin::boot()), so front-end output is identical either way. Pasting a shortcode into the block editor auto-converts it to the matching block via a transforms.from shortcode transform.

Block options

Four blocks have sidebar (inspector) options:

Block	Attribute	Default	Effect
us-scheduler/booking	loginPageId (number)	0	Page the "log in to book a lesson" link points to for logged-out visitors. 0 = the WordPress login screen (with a redirect back to the current page).
us-scheduler/booking	autoRedirect (boolean)	false	Send logged-out visitors straight to the login page instead of showing the link.
us-scheduler/student-login	bookingPageId (number)	0	Page the "View available lessons" link points to for logged-in visitors, and the post-login redirect target. 0 = the current page.
us-scheduler/student-login	autoRedirect (boolean)	false	Send logged-in visitors straight to the booking page instead of showing the link. Does nothing until a booking page is chosen.
us-scheduler/student-register	loginPageId (number)	0	Page students continue to once registration finishes — the "Sign in to your account" link after they confirm their email, and the "Continue to your account" link an invited student gets on the spot. 0 = the WordPress login screen for the confirmation link, and no link at all for the (already signed-in) invited student. Shortcode equivalent: [us_student_register login_page_id="…"].
us-scheduler/student-register	autoRedirect (boolean)	false	Send students straight to that page instead of showing the link. Does nothing until a page is chosen — there is no login-screen fallback here.
us-scheduler/group-classes	offeringId (number)	0	Restrict the page to a single group class, for embedding on a page dedicated to that class. The class description is then omitted — only the schedule, instructor, price and enrolment controls are shown, so the surrounding page's own copy is not repeated. 0 = browse all classes, descriptions included. Shortcode equivalent: [us_group_classes offering="…"].

The page selects list all published pages; if a chosen page is later deleted, the blocks fall back to their defaults. The group-classes block's class select is a dropdown of active group classes fetched from GET /us-scheduler/v1/offerings?kind=group_class; a stored class that is no longer offered shows as "Unavailable class #N" rather than silently falling back to all classes. The link targets are also available to the shortcodes as [us_booking login_page_id="…"] and [us_student_login booking_page_id="…"]; auto-redirect is block-only.

Auto-redirect cannot happen during block rendering (output has already started, so a Location header cannot be sent). Instead BlockRegistrar::maybeAutoRedirect() runs on template_redirect, parses the queried singular post's content for the block (including inside nested blocks), and redirects when the block opts in. A block whose target is its own page is ignored to avoid a redirect loop.

The registration block's auto-redirect additionally only fires on a finished registration — RegistrationPage::isRegistrationComplete(): an invited student who is now logged in (?us_registered=invite), or a self-signup back from the emailed confirmation link (?us_confirmed=ready|1). The intermediate "check your email" step and every failure (a validation error, ?us_confirmed=expired) stay on the page so the student reads the message. That check runs before the content is parsed, so an ordinary page view does not pay for the extra block scan.

How it works

• BlockRegistrar (src/BlockRegistrar.php) hooks init and registers each block with register_block_type(): a render_callback per block, the shared editor script (assets/js/blocks.js, handle us-scheduler-blocks), and the front-end stylesheet (assets/css/frontend.css, handle us-scheduler) as the block style so it also loads inside the editor and previews pick up theme styling.
• assets/js/blocks.js (vanilla JS, no build step) registers the client side of each block — title, icon, keywords, shortcode transform — and renders the editor preview with wp.serverSideRender, which fetches the server-rendered markup via the /wp/v2/block-renderer REST route.
• BlockPreview (src/BlockPreview.php) supplies static, script-free markup for editor previews. BlockRegistrar::isEditorPreview() detects the block-renderer context via the REST_REQUEST constant (front-end template rendering never happens inside a REST request) and renders the preview instead of the live page.

Editor preview behaviour

Live pages cannot run in the editor: booking and group classes are populated by JavaScript making authenticated REST calls (and may load Stripe.js), registration requires a valid invite token, and login short-circuits for logged-in users (the editing admin always is). Each preview therefore reproduces the live wrapper elements and CSS classes with representative placeholder content:

• Booking — #us-booking-app with sample .us-day / .us-slot rows and disabled Book buttons.
• Group classes — #us-group-app with a sample .us-class card and a disabled Enrol button. When offeringId pins a single class the preview drops the sample description, matching what the live page renders in that mode.
• Login — the real templates/frontend/login-page.php template (it has no request-state dependencies).
• Registration — a disabled sample of the .us-register-form fields.

Each preview starts with a .us-editor-note paragraph explaining what the published page shows instead. The note class only appears in editor previews.

Tests

• tests/Unit/BlockRegistrarTest.php — hook registration, block/asset registration, attribute schemas, front-end delegation to the page objects, preview-mode routing, auto-redirect behaviour.
• tests/Unit/Booking/BookingPageTest.php — logged-out login-link targets and fallbacks.
• tests/Unit/Auth/LoginPageTest.php — logged-in booking-link targets and fallbacks.
• tests/Unit/BlockPreviewTest.php — preview markup mirrors the live CSS classes/ids and includes the editor note.
