I have a form with various fields on it that I want to make sure

on a textarea if the user simply hits a space or return and submits
the form.
You can always 'trim' before you do the empty check. Just assign to a
variable first since empty doesn't do non-var expressions
$value = trim($value);
if (empty($value)) {
// error not filled in
}
Of course, you'll also want to validate the data type is a string or
number also, etc...and not an array. This is the goal of the up and
coming input filtering features.
