Note Submitter: thek at o2 dot pl ---- There is a trap when making "form prefilters". Something like $_POST = array_map('trim', $_POST) may be not what we wanted, because when there are arrays in form made by field[] this "prefilter" return not an array but, according to his behavior, string. So as a effect we see in var_dump not array but field = "Array" what can mess up our validation.
