Re: ISSET() question

Apparently isset() is not working, because it thinks that a blank text
field is set to something.

Yes, if the value of a field is "", then it is still set. You would want to test for both:

if ( isset($_POST['name']) && ($_POST['name'] != "") ) ...

Or, if you want to count " " as blank:


if ( isset($_POST['name']) && (trim($_POST['name']) != "") ) ...

There may be a more efficient way to do this - anyone know of one?
