UI-Components - values beeing sent to PHP

I have a form in my flashdocument with two textinputs and one button. User, pass, and submit.
Yeah, as you might have understood by now, it’s a login-form.

Anyway, my question is - how can I submit this information to ‘actions.php’ through POST?


on (press) {
	getURL("actions.php", "_self", "POST");
}

seems to be insufficient.

Anyone able to help?
