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.
