I want to trim any whitepace and check if it is empty in the same line this is not working.

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.
