Blank Field Detection - Problem

I am trying to detect in ajax what is an empty field. ( echo $field;→> output - radios)

This one if (!data.livre && data.livre == "radios") {checks to see if it is data.livreinvalid (this works) and now I want to check if the radio echo is or not. If this is a radio, I showed the user: empty radio stations

function check($form) {
            $fields = array("radios", "age");
            foreach($fields as $field) {
                if(empty($form[$field])) {
                    echo $field;
                    return false;
                }
            }
            return true;
    }

    $data = array();
    $data['livre'] = $val-> check($form);
    echo json_encode($data);

JSON Output:

radios{"livre":false}

js

        success: function(data) {
             if (!data.livre && data.livre == "radios") { //problem here
                $("#msgbox1").fadeTo(200, 0.1, function() {
                 $(this).html('empty radios').addClass('messageboxerror1').fadeTo(900, 1);      
                });
            }
        }

EDIT. What is the best way to determine if an empty field is radio or age?

If the result could be that only the radio stations or age or none of them can be empty, you need to change your check to !data.livres || data.livres == "radios" || data.livres == "age". Then it will display a message if your json output is as follows:

{livres: false}

or

{livres: "radios"}

or

{livres: "age"}

Edit: Changes as per your comment

if (!data.livre) { //problem here
  // Do whatever you want to do when livres is false
} else if (data.livre == "radios") {
  // Do whatever you want to do when livres is "radios"
} else if (data.livre == "age") {
  // Do whatever you want to do when livres is "age"
}
