<p>WhenPilot is a lightweight appointment booking plugin for small businesses — salons, clinics, consultants, tutors. Everything stays on your own site; there is no third-party booking service.</p>
<p><strong>Features</strong></p>
<ul>
<li>Define <strong>services</strong> (name, duration, optional price, description).</li>
<li>Set your <strong>weekly opening hours</strong> in a simple text format (e.g. <code>Mo-Fr 09:00-17:00</code>).</li>
<li>Visitors book with the <code>[whenpilot]</code> shortcode: pick a service, a date, and a <strong>free time slot</strong> computed from your hours and existing bookings.</li>
<li><strong>Double-booking prevention</strong>: slots are re-validated on the server before saving, with a configurable capacity (e.g. number of staff).</li>
<li><strong>Admin inbox</strong>: see upcoming/pending/confirmed/cancelled bookings, confirm, cancel or delete.</li>
<li><strong>Email confirmations</strong> to the customer and a notification to you, plus emails when you confirm or cancel.</li>
<li>Configurable lead time, how far ahead people can book, currency label and an optional auto-confirm.</li>
<li>Uses your site’s timezone. Works with any theme.</li>
</ul>
<p><strong>Usage:</strong> create a page, add the shortcode <code>[whenpilot]</code>, and publish.</p>
<p>All features described above are fully functional in this plugin — no time limits, no usage caps, no locked options. WhenPilot does not connect to any external service. A separately distributed companion plugin offers additional features (multiple staff/resources with custom fields, automatic email reminders) but is not required for the plugin to work.</p>
<h3>Privacy</h3>
<p>Bookings (name, email, optional phone and notes) are stored in your own database and emailed to you and the customer. No data is sent to any third party.</p>

<p>Appointment SW lets visitors book appointments from any page on your site. You configure as many working windows per day as you need, block holidays, optionally allow guest bookings, and Appointment SW takes care of slot availability, email notifications and capability checks.</p>
<p>Version 2.0 is a deep modernisation of the original plugin while keeping every shortcode, option and database table from 1.x in working order. Existing sites can update without re-doing setup.</p>
<h4>What’s new in 2.0</h4>
<ul>
<li>Modern booking flow: clicking a free slot opens a confirmation modal — no more page reloads to advance the booking.</li>
<li>Admin booking modal with live client search and an inline “Add client” button, so receptionists can book a brand new client without leaving the calendar.</li>
<li>Arbitrary number of time windows per day (not just two).</li>
<li>Server-rendered Settings page using the WordPress Settings API, with an onboarding section that creates the shortcode pages for you in one click.</li>
<li>Public REST API under <code>/wp-json/appointmentsw/v1/</code> for availability, bookings, holidays, settings, and user search.</li>
<li>Capability-based permissions: <code>appointmentsw_manage</code> (administer) and <code>appointmentsw_book</code> (book a slot).</li>
<li>Prepared statements across every database query, plus new indexes on bookings, bookmeta and holidays for faster lookups on busy calendars.</li>
<li>Hardened request dispatcher: strict capability checks, sanitized input and escaped output throughout.</li>
<li>Filterable email templates via <code>appointmentsw/email/{event}/{audience}/{subject|body}</code>.</li>
<li>Optional WooCommerce integration is now a separate companion plugin so this core stays lean.</li>
</ul>
<h4>Shortcodes</h4>
<ul>
<li><code>[appointmentsw_form]</code> — booking form for visitors.</li>
<li><code>[appointmentsw_myaccount]</code> — logged-in user appointments (view and cancel).</li>
<li><code>[appointmentsw_admin]</code> — frontend admin calendar with client search and one-click client creation.</li>
<li><code>[appointmentsw_vacations]</code> — block holidays from the frontend.</li>
</ul>
<h4>Backwards compatibility</h4>
<p>All 1.x shortcodes keep rendering, bundled Bootstrap 3 assets are still enqueued so existing theme overrides keep working, the legacy <code>core/</code> classes remain loaded, and legacy options (<code>asw-guest</code>, <code>asw-duration</code>, <code>asw-numdays</code>, <code>asw-maxoffset</code>, <code>asw-start_time_*</code>, <code>asw-end_time_*</code>) are migrated transparently into the new <code>appointmentsw_settings</code> option the first time the new code reads them.</p>
