Hello, im new to this forum and im glad i found it. Hope you can help me

My problem is:
Im trying to present values from from into txt or html file. I think i should show you what im trying to do here

(form, sry i forgot to draw "submit" button, it is there

(this is how it should be after you send the values from previous picture)

Im sort of n00b in php, so guide me as a dumb
I need this for my personal projekt, so i can learn some php as well.
I was thinking maybe it should all be made with jquery/ajax? Coz it looked like a real pain to validate the input fields and it can get messy if i dont use recaptcha.

What should do?
