To anyone reading this, I've solved this problem myself.
It appears that the rules in the a multiple validation rule are read
from BOTTOM to TOP!
Hence if I arrange my multiple rules in the table like so, I get the
VALID_NOT_EMPTY rule tripping the validation mechanism before the
other rules.
'username' => array(
// needs to be at least 4 chars long
'minrule' => array(
'rule' => array('minLength', 4),
'required' => true,
'allowEmpty' => false,
'message' => 'Your Username must be at least 4
characters
long.'
),
// must be alphanumeric
'alphanumeric' => array(
'rule' => 'alphaNumeric',
'message' => 'Only alphabets and numbers allowed.'
),
// must be a unique name
'unique' => array(
'rule' => 'isUnique',
'message' => 'This username has already been taken.'
),
// needs to be at least 4 chars long
'notempty' => array(
'rule' => VALID_NOT_EMPTY,
'message' => 'Username Can not be Empty.'
),
),
Thanks,
August
