Use... $this->data[$this->name]['fieldname']
function checkEmpty($value) {
$valid = false;
if ($value == 'c' && !empty($this->data[$this->name]['field4']) {
$valid = true;
} elseif (($value == 'a' || $value == 'b') &&
!empty($this->data[$this->name]['field2']) &&
empty($this->data[$this->name]['field3'])) {
$valid = true;
}
return $valid;
}
I often use pr($this) in my model to figure out how certain things
work.
Cheers,
Adam
