### Technical assignment for the programmer
Project: Event booking system on the WordPress site for CFA.
Goal: Develop functionality for booking events through the WordPress site, including user verification against the database and integration with Google Calendar, as well as the ability to store booking data in .xls format on Google Drive or in the site's database.
#### 1. Main functionality:
- User authorization:
- The user enters their phone number in a specific format or the email they used to register with CFA.
- After clicking "Submit," the system checks the entered data against the database (Main Body).
- If the data is found, the user proceeds to the next step of booking.
- If the data is not found, an error message is displayed suggesting to re-enter the data.
- Event booking:
- After successful authorization, the user sees available event dates for booking.
- The user selects a date and proceeds to choose a time.
- After selecting a time and clicking the "Book" button, the selected time becomes unavailable for other users.
- Notifications:
- After successful booking, the user receives a notification via SMS and email with information about the booked time.
- The user can add the event to Google Calendar via a link in the notification.
#### 2. Administrative functions:
- Schedule management:
- The administrator has the ability to set available dates and time slots for booking through the WordPress admin panel.
- Storage of booking data:
- Information about bookings (date, time, name, email, phone) is saved as an .xls file on CFA's Google Drive or in the site's database.
- Analysis:
- Google Drive may be convenient for remote storage and data sharing.
- The local database of the site will ensure faster processing and automation.
- Recommendation: Use the site's database for data storage and provide export in .xls format for manual or scheduled upload to Google Drive.
- Viewing and printing the list of bookings:
- The administrator can easily view and print the list of bookings through the WordPress interface.
- Booking cancellation:
- The user and administrator can cancel a booking, after which the time becomes available for selection by other users.
#### 3. Additional requirements:
- Data security:
- All personal data of users (phone and email) must be protected in accordance with security standards.
- Interface:
- A simple and clear interface for users and administrators.
- Scalability:
- The system must be ready to accommodate an increasing number of users and events without degrading performance.
#### 4. Integrations:
- Google Calendar: Automatic integration for adding events to the calendar.
- SMS notifications: Use API to send SMS messages about bookings.
#### 5. Proposed development stages:
1. Development of the authorization mechanism via phone number and email.
2. Setting up the database to store information about users and events.
3. Creating an interface for booking events.
4. Integration with Google Calendar and setting up notification sending.
5. Implementation of an admin panel for managing events and data export.
