As, in this case, only one of the variables is non-null, then you could use
the string concatenation operator and this would return what you want.
i.e. type = $_POST['news'] . $_POST['dreams'] . $_POST['storys']...
I think I've used the same variable name in different forms on the same page,
as only one form submission occurs at any one time there can't be a conflict
and PHP doesn't care where the POST'ed variable came from.. So, you could
rename news, dreams, etc. to be type and extract the result directly without
having to fiddle around.
