Installation

1. Copy this project to: wp-content/plugins/crane-booking-manager
2. Activate the plugin in WordPress Admin → Plugins.
3. On activation, the plugin:
   • creates DB tables,
   • runs schema migrator,
   • creates default resource (Resource #1) when none exists,
   • grants manage_cbm_bookings capability to administrators,
   • creates role cbm_operator,
   • creates secret key (cbm_secret) for cancellation tokens.

Quick Start

1. Go to Bookings → Settings and configure:
   • resource labels (singular/plural),
   • working hours,
   • slot duration (30 or 60 minutes),
   • minimum advance notice,
   • reminder and email settings,
   • optional Turnstile keys.
2. Go to Bookings → Resources and define your real resources.
3. Insert shortcode on a page:
   • [crane_booking_form]
   • [resource_booking_form]
   • Optional attribute: resource_id, for example: [crane_booking_form resource_id="2"]

Frontend Booking Flow

1. User selects a day in the inline calendar.
2. Plugin loads available start times for that day/resource.
3. User picks start time; plugin computes valid end times with:
   • minimum 3-hour duration,
   • working-hours boundary,
   • blocked/busy ranges.
4. User submits contact and booking data.
5. Booking is created with status pending.

Validation and protection:

• Field validation (date/time format, required fields, email correctness).
• Nonce validation on booking API.
• Rate limiting: 5 requests / 10 minutes per IP.
• Duplicate-submit protection via short-lived submit_token.
• Optional Turnstile server-side verification.
