I think the first method should work if you use "and" or "&&" (logical
operators) instead of just "&" (bitwise operator, which doesn't do what
you want here).

The second method doesn't work because an empty string "" is not the
same as an unset value, which is what you get if Delete doesn't exist in
the $_POST array at all. Instead, try:

if (isset($_POST['Delete'])) {
