Is it alright to do this?
$author = strtolower($_SESSION['valid_username']);
I want to enter all authors into the table as lower case.

A:
Yes, that's fine as long as $_SESSION['valid_username'] is set, otherwise you'll get a notice (if your error reporting is set that low).
You can check if it exists with if (isset($_SESSION['valid_username']))

Like this?if(isset($_SESSION['valid_username'])) $author = strtolower($_SESSION['valid_username']);

Yup... then you probably want something like else $author = '';

or something like else throw new Exception('Error: Username is not set!')

A:
yes.
$_SESSION['valid_username']
is a session variable which evaluates to a string so passing it as a parameter to the strtolower function is not a problem.
