That's because Radio Buttons and Check Boxes do not return anything if not
checked or selected.
So you gotta explicitly do it ur self. That is u gotta check for it's
validity and non-empiness.
e.g. in ur scenario
if(!isset($_POST['radio_test'])) { //print out all the options unselected }
else
{ // print the value and show the rest empty in the report }
