identify customers by name

[Guest]

is it possible to allow a portion of one's site to be restricted to everyone else except people with the name "sam" or "samantha" or "samuel"?

 

similar to how you can allow the shopping cart to only be seen if there's items:

if ($cart->count_contents() > 0) {

require(DIR_WS_BOXES . 'shopping_cart.php');

}

 

i want the same kind of effect
