I was wondering how can I allow NULL values in the following code below along with keeping WHERE username = '$username'.
here is the mysql code.
"SELECT *
FROM users
WHERE username = '$username'
AND user_id <> '$user_id'"
I'm trying to check for usernames with the same username but I want all users to have a NULL value if they want.
