The following script is from Kevin Yank's book (Sitepoint).
When I test it _without_ entering a name in the text box and hit submit, the
_next_ page
loads - however the same page should load beacuse of the conditional
........
if (!isset($name) ):
.....
If I replace
!isset()
with
empty()
like
if (empty($name)):
and do not enter a name then the _same_ page loads which is what is supposed
to happen.
Why doesn't the call to !isset() with the negation mark loads the next page
when a name is not entered?
The script predates globals being turned off and it is below.
Thank you.

<p>This paragraph contains a <a

variable on to the next document.</p>
