This way, the condition only applies when both sub-conditions are true (both
fields are non-empty); replace the && between the sub-conditions with ||

if ((isset($v) && $v !=='') || (isset($v2) && $v2 !=='')) {
...
}

That's because with the ||, only one test has to pass. Also note that you
are not compatring values (==) but assigning them (=).
