I use preg_match to validate the Middle Initial field of a form and so far
it works, except yesterday a user submitted a 0 (zero) as a middle
initial! My regexp is:
if (!empty($_POST[MI]) (preg_match('/^[[:alpha:]]{1,1}$/', $_POST[MI]) == 0))
I tested it with 0-9 and my regexp catches every

Not an answer but
'/^[[:alpha:]]{1,1}$/'
could be writen as
'/^[[:alpha:]]$/'

if (isset($_POST[MI]) (preg_match('/^[[:alpha:]]{1,1}$/', $_POST[MI]) == 0))

I believe I spoke too soon. If I use isset() then even if I leave the
field empty it still returns true. I am trying to view the documentation for
this function but php.net seems to be timing out now.
