Hi,
try this:
if (isset($_POST['_createcategory']))
{
$value = trim($_POST['_createcategory']);
if (empty($value))
{
Be very careful with empty(). It doesn't do exactly what it says on the
tin. For example if your _createcategory POST value contained a zero,
the empty() check will fail in the above instance, giving a false result.

You're right.
This function is a good workaround:
//taken from http://php.net/empty
//24-Mar-2007 02:32
function is_empty($var)
{
return (((is_null($var) || rtrim($var) == '') && $var !== false) ||
(is_array($var) && empty($var)));
}
Best regards
Tim
