About this tool.
Appointment Hour Booking is a WordPress plugin for creating booking forms for appointments with a start time and a defined duration over a schedule. The start time is visually selected by the end user from a set of start times calculated based in the “open” hours and service duration . The duration/schedule is defined in the “service” selected by the customer. Each calendar can have multiple services with different duration and prices.
This plugin is useful for different cases like booking of medical services where services with different duration and prices may be available, for personal training sessions , for booking rooms for events , for reserving language classes or other type of classes and other type of services/resources booking where start times are selected and the availability is automatically managed using the defined service duration to avoid double-booking (the booked time is blocked once the booking is completed).

Sample cases: Medical services, personal training, resource allocation, booking rooms, classes, etc…
The services can have a maximum capacity (example: number of persons that can book/attend the service at the same time). The default capacity is 1. If the service capacity has been set to 1 the time-slot will be blocked for new bookings after getting one booking. If the service capacity has been set to a greater number (example: service with capacity 10) the time-slot will be blocked after filling the capacity (example: after getting bookings for a total of 10 persons). This feature is described in detail at https://apphourbooking.dwbooster.com/blog/2019/01/24/bookings-for-multiple-persons/
The Troubleshoot Area
Use the troubleshot if you are having problems with special or non-latin characters. In most cases changing the charset to UTF-8 through the option available for that in the troubleshot area will solve the problem.
You can also use this area to change the script load method if the booking calendar isn’t appearing in the public website.
The Notification Emails
The notification emails with the appointment data entered in the booking form can sent in “Plain Text” format (default) or in “HTML” format. If you select “HTML” format, be sure to use the BR or P tags for the line breaks into the text and to use the proper formatting.
Exporting Appointments to CSV / Excel Files
The appointment data can be exported to a CSV file (Excel compatible) to manage the data from other applications. That option is available from the “bookings list”, the appointments can be filtered by date and by the text into them, so you can export just the needed appointments to the CSV file.

The styles for the list are located at the end of the file “css/stylepublic.css”:
.cpabc_field_0, .cpabc_field_1, .cpabc_field_2, …
Clear the browser cache if the list isn’t displayed in a correct way (to be sure it loads the updated styles).
You can also add the needed styles into the “Customization area >> Add Custom Styles” (at the bottom of the page that contains the list of calendars):
