RE: [PHP] Not sure of my error

Right .... Sorry ... I just woke up 25 minutes ago and late to work - my brain is still sleeping ... :-))) if (!isset ($state)) { $then = 'Go'; } Cheers!

I am used to using empty() and isset() for such things. Joe, why do you always have to be so different? ;-) Wonderful how flexible this all is huh? At any rate, I would do this : <?php if (empty($state)) { echo 'Enter state please!'; } else { echo 'Your state was '.$state; } ?> I know that if $state were '0' then it is not considered empty, but this does not seem to apply here, right? Always looking for new little tips ... philip -- be outside the box.
