What's wrong with:
if (empty($_POST[$key])):
?
This should work whether or not register_globals is switched on, and is therefore much
to be preferred.
Cheers!

That did it.
I assumed that since $_POST was global, the key/value pair would be. Guess
not :-|
Thanks!

Since php variable scope is local unless you define it global, that won't
work that way. You might try (just guessing here):
function myFunction() {
foreach($_POST as $key=>$value) {
global $$key;
if (empty($$key)) {
print "empty value $key";
}
}

[PHP] Using Variable Variables from form values inside a function
Is it possible to use variable variables from form values inside a function.
For example when submitting form values, this works fine:
foreach($_POST as $key=>$value) {
if (empty($$key)) {
print "empty value $key";
}
}
but, this doesn't:
function myFunction() {
foreach($_POST as $key=>$value) {
if (empty($$key)) {
print "empty value $key";
}
}
}
Anyone dealt with this?
