Fill in a form (and send it) from Elisp

[Emanuel Berg <emanuel.berg.8573@xxxxxxxxxxxxx>]

How do you do that?

My attempts so far:

(fset 'login-name "embe8573")

(defun web-login ()
  (interactive)
  (w3m-next-anchor 6) ; this works
  (w3m-view-this-url) ; and this
  (execute-kbd-macro (symbold-function 'login-name)) )

But the last line doesn't work, so perhaps the whole
"macro idea" is a dead end.

If I know the configuration of a form beforehand, how
can I write Elisp to fill all fields with data, and
then likewise pragmatically push the "send" (or so)
button?
