ESP8266 Arduino IDE - How to transfer data from Text Box to ESP?

Hello.
I am trying to write a program in arduino ide for esp but I have no idea how to write a simple page in which I will have text boxes. It would send the information stored in them to esp when a button is pressed.
I have searched the internet to find a solution but have not found a solution even similar.
I already know how to make pages on esp (I will start in html) but how to solve the communication in the computer --->esp side I have no idea.
I don't expect a ready-made solution but at least some guidance.
Greetings;)

You can take a look at this material.

In Arduino you have File->Examples->ESP8266WebServer, and inside you have example servers. You can see WebUpdate - it's a more complex build for downloading a file - but a good example. Parameter downloading is well described Here . More extended description Here
