Using liveview form to send data back to controller

In LiveView how can I pass my data back to the controller? Non-liveview like Route.path_helper(conn, :new, user: @user, employee: @employee). I need the same map or keyword list as shown.

This is my latest iteration. I need those user and employee fields attached to each form, so I can’t just use html. Where can I put such a list of values here?

    <.form let={_f} for={:alert}  phx-submit={:alert}  #user: @user, employee: @employee>
        <%= submit "Alert1", class: "btn btn-primary" %>
        </.form>

Then in the controller. I need value to be a map (or whatever)

def handle_event("alert", value, socket) do
   IO.inspect(value) => {} # is currently an empty map. Only the first arg is correct.

I’ve asked on this question use form_for in liveview component without model or changeset. And this is similar to this too live_component inside of a form_for
