Skip update specific field on some condition

[betterapp]

In documentation there is only information about skipping all Item update by return null in one of Key field.

But I need to skip update some specific field os some conditions but the rest I need to update.

As I see if I return "false" from field settings the field is not updated. This works for relation field. But how can I skip update other field type - for example boolean, or text ?

Is it possible ?

Yes, this is possible: You can return $params['currentValue'] in the field's callback function when you want to keep the current value, e.g.

if(strlen($params['value']) > strlen($params['currentValue']) {
  return $params['value'];
} else {
  return $params['currentValue'];
}
