Hi hope you’re all doing great!
I am trying to find good tutorials on how to develop a Wordpress plugin using HTML, CSS, JS, PHP and MySql.
I am searching to be able to build a front end booking system that has a backend dashboard to manage the bookings and connected to different APIs such as Google Calendar, Google Sheets etc.
I know that in the front end I will absolutely need CSS, HTML and JS. But I am a bit lost on how to structure everything and how to keep all the secret data only available in the back-end (I think I have to code most of it in PHP).
Thanks for your help!
