How can I make my if condition more simple?

I was trying to find a shorter way to write this if condition:

if($template == "documents"){
  $slug = $template;
  $parent = "products";
} else {
  $slug = $slug;
  $parent = $parent;
}

This is my approach:

$slug = ($template == "documents") ? $template : $slug;
$parent = ($template == "documents") ? "products" : $parent;

I have the feeling this code could be reduced more. But I do not know how.
