there can be only rone adio selected in a group

you group them assigning the same name attribute
in POST you will receives the value of the selected radio

TexWiller is correct, this code seems to be accurate since you only want one value from the radio button, or you would be using a checkbox. You can only select one radio button within a form, so the value is unset when you POST the data.

If you give them different names, you can identify which was seleteted.

if(isset($_POST['upgrade1']))
{
    $upgrade = $_POST['upgrade1'];
}
elseif(isset($_POST['upgrade2']))
{
    $upgrade = $_POST['upgrade2'];
}

if(isset($_POST['upgrade3']))
{
    $upgrade = $_POST['upgrade3'];
}

Also, a general note, it's good practice to also validate your form data server side in addition to client side with JavaScript. It can be very easy to POST data direct to the server, which will then bypass any sort of validation.
