They both work, you're just not using the correct logic or something.
Show your code again... your actual code that isn't working (so you say)
and the form that's being submitted. Also, is register_globals on or
off?
Load this small bit of code as proof that it works:
<form method="POST">
<input type="text" name="name">
<input type="submit">
</form>
<?
if(isset($_POST['name']))
{
echo "You submitted a name ";
if(empty($_POST['name']))
{ echo "that was blank."; }
else
{ echo "of {$_POST['name']}"; }
}
?>
