Note that amongst other things "0" is considered empty.

try to print the post value first.. i.e print_r($_POST);

[Guest Tim_Christopher]

Try:

if (    empty($_POST["email"])
   || empty($_POST["username"])
   || empty($_POST["password"])
   || empty($_POST["cpass"]))
{
   echo 'One or more empty fields';
}
else
{
   echo 'All fields are not empty';
}
