Mulitple variables

[Crew-Portal]

how do I assign an if statement to multiple varibles?

Like if I want it so that if a member tries to login without giving a name or password i want it to display a error but how do i do it

is it like:

 

if ($passwd || $usernm == NULL){

$error = 'You Did Not Enter A username Or Password';

}

[teng84]

if (empty($passwd) || empty($usernm )){

$error = 'You Did Not Enter A username Or Password';

}
