ผมต้องการจะทำ Radio box แบบ 3 ปุ่ม โดยมีเงื่อนไข(ต่อด้านในน่ะครับ)

<?php
if ($_POST["rdoOption"] == "1") {
    // Do 1
} elseif ($_POST["rdoOption"] == "2") {
    // Do 2
} elseif ($_POST["rdoOption"] == "3") {
    // Do 3
}
?>

<? 
include "config.inc.php";

$con = mysql_connect($host,$username,$password);
