Conditional/Check: IF author has no First Name THEN

The second parameter for get_the_author_meta is the user iD.

If you’re using the function within the loop, the user ID would be the ID of the current user if not you would have to specify the user ID.

if ( !get_the_author_meta('first_name', $user_id )) {
    // do something
}
