I want to trim any whitepace and check if it is empty in the same line this

You can't do this because empty needs the variable - it can't work on
teh return value. The closest you can get would be...
if (isset($_POST['_createcategory']) and
strlen(trim($_POST['_createcategory'])) > 0) {
Not as neat, but it does the job.
You could also do something like this...
$_POST['_createcategory'] =
isset($_POST['_createcategory']) ?
trim($_POST['_createcategory']) : '';
if (empty($_POST['_createcategory'])) {
Still not pretty but slightly better in that you can cleanse your data
before you hit logic.
