Development of a web application based on MySQL database

Hello,

I have a web application that serves as a booking calendar and is based on a MySQL database.

Services:

- MySQL database

- SMTP server

Installed packages:

- Bulma 0.9.4 (cdn)

- Font-Awesome 6.4.0 (cdn)

- FullCallendar.js 6.1.5 (local)

- SweetAllert2.js (cdn)

- PhpSpreadSheet 1.28 (local)

I would like to extend the application with the following functionality:

1. adding an online payment option for services

- Integration with existing przelewy24 system after API

2. possibility to give feedback

- After the completed service, the customer has the opportunity to give feedback for the completed service (star rating system + comment)

- Reporting of opinions

3. saving service reservation in Outlook calendar

Integration with Outlook calendar - adding an option to save the visit in Outlook calendar.

4 Absence report

- Ability to mark bookings where the client did not show up for the visit

- Ability to report absences

5 Blocking records above the norm

Field that allows you to define how many times a given employee / company can use the reservation in a month.

6. adding an option that allows the user to edit/delete the account
