Well, you could use a simple foreach:
foreach ($_POST as $key => $value){
if($value === '') { print("You must fill in all the values");}
else{continue;}
}
I'm not sure if empty($value); would work, but its worth a try.
You could however use it, within the foreach by doing:
empty($_POST[$key]);
(if $key = name, it would test $_POST[$name] whether it is empty or not).

I would assume that empty() would work in this case eitherway, and is
most likely your best bet.
However, within this function it may also be smart to include a few form
validation rules for the security of your form as well.
