Han,

You might have had display errors turned off in PHP 4.

It's always good to see if something exists before trying to use it. I
use isset($_POST['varname']), but I'm sure array_key_exist will work
just fine.

My code looks something like:

$var = isset($_POST['varname']) ? $_POST['varname'] : 'default_value';

That way I can set a default - even if it is null.
