Jquery validation

Jquery validation

Hi  

My remote PHP function return two values. 1 and 2.

How can i catch those values and put in to separate error messages.

$coupon_code    =  $fw->xss()->safe($_REQUEST['coupon_code']);
$coupon_code = $fw->voucher()->getByCodeStatus($coupon_code);
console.log($coupon_code);
//return 2 means no value in the credit card //
if($coupon_code == 1) //
{
echo("false");
}else if($coupon_code == 2){
echo("false");
}else{
            echo("true");
        }

coupon_code:{
remote:{
url:ajaxpath,
type:'post',
data:{
coupon_code:function(){
return $('#coupon_code').val()
}
}
}
},
