Everything stays on your own site; there is no third- party booking service. **Features** * Define **services** (name, duration, optional price, description). * Set your **weekly opening hours** in a simple text format (e.g. `Mo-Fr 09:00- 17:00`). * Visitors book with the `[whenpilot]` shortcode: pick a service, a date, and a** free time slot** computed from your hours and existing bookings. * **Double-booking prevention**: slots are re-validated on the server before saving, with a configurable capacity (e.g. number of staff). * **Admin inbox**: see upcoming/pending/confirmed/cancelled bookings, confirm, cancel or delete. * **Email confirmations** to the customer and a notification to you, plus emails when you confirm or cancel. * Configurable lead time, how far ahead people can book, currency label and an optional auto-confirm. * Uses your site’s timezone. Works with any theme. **Usage:** create a page, add the shortcode `[whenpilot]`, and publish. 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. ### Privacy 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. ## Screenshots [⌊The booking form on the front-end with the inline month calendar — visitors pick a date, then a free time slot.⌉⌊The booking form on the front-end with the inline month calendar — visitors pick a date, then a free time slot.⌉[ The booking form on the front-end with the inline month calendar — visitors pick a date, then a free time slot.

Upload the `whenpilot` folder to `/wp-content/plugins/`, or install the zip via Plugins Add New Upload. 2. Activate the plugin (this creates the tables and a sample service). 3. Go to Bookings Services to add your services, and Bookings Settings for your hours. 4. Add `[whenpilot]` to a page. ## FAQ ### Can two people book the same time? Only up to the capacity you set (default 1). Slots are re-checked on the server at the moment of booking, so overlaps are prevented. ### Does it support online payment? Not in this version — it collects booking requests. You confirm them from the admin inbox. ### Which timezone is used? Your WordPress site timezone (Settings General). ### Is there a paid version? WhenPilot Pro adds unlimited services, capacity greater than 1, multiple staff/resources, custom form fields and automatic email reminders. The free version on this page is fully functional for a single service and is not time-limited. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “WhenPilot” is open source software.

No functional changes. * Bumped minimum WordPress version to 6.2 (required by the `%i` placeholder). #### 1.0.2 * Fixed: calendar weekday columns could be misaligned when the site’s “Week starts on” was not Sunday. #### 1.0.1 * New: the booking form now uses an inline month calendar to pick the date (closed days and past dates are greyed out) instead of a plain date field. #### 1.0.0 * Initial public release: services, weekly hours, free-slot booking form, double- booking prevention, admin inbox and email confirmations. ## Meta * Version **1.0.4** * Last updated **2 days ago** * Active installations **Fewer than 10** * WordPress version ** 6.2 or higher ** * Tested up to **7.0** * PHP version ** 7.4 or higher ** * Tags * [appointments](https://wordpress.org/plugins/tags/appointments/)[booking](https://wordpress.org/plugins/tags/booking/) [calendar](https://wordpress.org/plugins/tags/calendar/)[reservations](https://wordpress.org/plugins/tags/reservations/) [scheduling](https://wordpress.org/plugins/tags/scheduling/) * [Advanced View](https://wordpress.org/plugins/whenpilot/advanced/) ## Ratings No reviews have been submitted yet.
