I tried that... no luck. I think it's because there's multiple answers and
all of them have the form input with name="aid", can't distinguish which
request.vars.aid to send... different answers would have different amounts
of likes... there's a for-loop statement above the form and each form has
the same name... if i distinguish the name to be name="aid{{=answer.id}}",
how do I get the value in the controller? request.vars.aid?
