Who understand Streaming?

Hello,
Since two weeks I am trying to program something that might not just be programmable. Any help welcome please.

I have an Arduino Uno Wifi to build a little plant watering system. I want to access it thru a webpage.
The thing is, on this webpage I want the user to be able to read humidity and to set a low and a high level of humidity to start and stop a pump.

I am connected to the wifi and if I use a command like input type=button it works.

But if I am using an input type = text and an input type = submit but it doesn't return anything.
How can I get the Arduino to receive the low and high settings that the user will provide thru a browser?

Any ideas will be much appreciated.

Many thanks,

Your question has nothing to do with streaming.
It is a simple web-server / HTML question.

Perhaps rename this post, and add your code (within </> code tags)
I'm sure you'll get some constructive hits.

This is an HTML question.

There is some information here.

Arduino Uno WiFi Developer Edition? with original firmware?

Yes,
Should i update the firmware?

This is an HTML question.

not really, OP has to serve up dynamically and accept input.

this is more than a HTML/JS question.

I am sure you have the newest 'factory' firmware 0.0.3 because it's old and discontinued. If not, update.
You use UnoWiFiDevEd.h with IDE 1.8.x?

You write about html elements used, but important is the http request send to Arduino and the response. Use some web debugging tool (F12, Fidller, ...).

I think that I regret buying this Uno Wifi. There is very little documentation, and half of it is not working.
Yes I have the latest IDE. I dont know which firmware version i had so I just upgraded. Thanks for you comments.
