Hi Danny,

You could use foreach to iterate through the post variables until you
encounter a match:
foreach ($_POST as $key => $value){
if (substr($key, 0, 6) == "radio_") {
$buttonName = $key;
$buttonValue = 4value;
break 2;
}
}
I haven't tried the above code, but I hope someone will correct my
efforts if I'm wrong.
