empty() and isset() are totally different.
If a variable is set, but is set to nothing (or a value of 0), then the
isset() will still hold true, whereas empty() will check that the variable
contains a value other than a blank or 0.
A workaround to the empty() statement?
if ( (isset($var)) && (!empty($var)) )
{
}
or:
if ($var!='')
{
}
There are other ways to do this but the main point is making sure the
varible is not passed as empty when the form is used.

Adam,
It's really better to use the isset() instead of empty() because if you set
the error level report to E_ALL you will see that PHP will produce warnings
if the variable is not set at all!

i might try:
this would also assume you need multiple functions to be used on the same
form as submit buttons. This seems like the most logical/simple way to do
it.
