Re: radio buttons in $_POST

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 } On 4/23/05, Ashley M.
