Drupal Views Filter Handler - drupal

Question

I wrote a custom views handler, that mark message private to 0 or 1 or 2; any is value of hers label [MARK_READ,ARK_NEW,...] :
function mydevel_views_data() {
$data['mydevel']['table']['group'] = t('mydevel');
$data['mydevel']['table']['join'] = array(
// Exist in all views.
'#global' => array(),
);
$data['mydevel']['mydevel_isnewmessage'] = array(
'title' => t('is new message field'),
'help' => t('is new message field.'),
'field' => array(
'handler' => 'mydevel_handler_field_isnewmessage',
'click sortable' => TRUE,
),
'filter' => array(
'handler' => 'mydevel_handler_filter_isnewmessage',
),
);
and wrote a filed handler that work properly; message_mark function is wrote on mydevel module file and work currectly; if the message is new that filed label row by "now":
class mydevel_handler_field_isnewmessage extends views_handler_field_numeric {
var $field_alias = 'mydevel_field_isnewmessage';
function query() {
}
function option_definition() {
$options = parent::option_definition();
//dsm($this);
return $options;
}
function options_form(&$form, &$form_state) {
parent::options_form($form, $form_state);
}
function get_value($values, $field = NULL) {
return intval(message_mark($values->mid, $values->message_timestamp));
}
function render($values) {
$value = $this->get_value($values);
$value_theme = theme('mark', array('type' => $value));
return $value_theme;
}
}
Now, i want to write a views filter handler that filter on that filed on numeric mode [0 or 1 or 2] or on check list mode [all, read, new, updated]. but I don't want to overwite query function on filter handler and want to use from value that returned by this common handler filed (mydevel_handler_filter_isnewmessage) that added to views filed. can wrote this idea by extend the standard views handler? what i do my dears? I wrote this but not work: this is return error
class mydevel_handler_filter_isnewmessage extends views_handler_filter_numeric {
var $always_multiple = TRUE;
function option_definition() {
$options = parent::option_definition();
return $options;
}
function operators() {
$operators = parent::operators();
return $operators;
}
function query() {
}
}
tank you a lot.
