Retrieving data from database

[LBC]

Nope. That's fine.
if($user->data()->membership == '5cc'){
$length = 6;
}elseif($user->data()->membership =='10cc'){
$length = 6;
}
if(isset($length)){
echo date('Y-m-d', strtotime("+".$length." months", strtotime($user->data()->validity)));
}

I think that will do it.

I'm afraid it doesn't display anything now. I have done it like this now:

<p><strong>Valid until:</strong>
        <?php if($user->data()->membership == '5cc'){
        $length = 6;
        }elseif($user->data()->membership =='10cc'){
        $length = 12;
        }
        if(isset($length)){
        echo date('Y-m-d', strtotime("+".$length." months", strtotime($user->data()->validity)));
        }?></p>
