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).
I had the same question. looking for professional guidance.
I’m stuck to chose between android development or Wordpress plugin development.
it would be greatfull for me thanks in advance.
My suggestion would be to code this without doing so inside a plugin. If once you get everything working the way you need you can then wrap the code inside a plugin. Personally I almost never do, I much prefer writing this kind of thing in a “Custom Page Template”.
Two plugins that may really be helpful are these:
This one because you cannot run php code inside the WordPress editor. This allows you to write a piece of php code and then just insert it’s shortcode into the editor. You could of course do this longhand, but I find doing it with code snippets helps me organize.
The second is:
ACF is really very excellent. This is my favorite way to persist information in a highly organized way to the database. Give the piece of data a name, save and retrieve it at will using a slick syntax.
There are lots of tutorials on ACF, and that is very helpful as well.
