How can I get the results?:
$check = mysql_query("select username, email, case
when max(username = '$username') > 0 and max(email = '$email') > 0 then 'both'
when max(username = '$username') > 0 then 'username'
when max(email = '$email') > 0 then 'email'
end
from school_users
WHERE username = '$username' or email = '$email'") or die(mysql_error());
I need "username" or "email" or "both" when it exists. How do I receive these variables?
