我正在为我的自定义帖子类型添加自定义管理员筛选器。我有点搞不清楚该怎么做parse_query 筛选，以便根据2个或更多筛选器筛选我的帖子。

最初，对于1过滤器，我可以执行以下操作：

$query->query_vars[\'meta_key\'] = \'city\';
$query->query_vars[\'meta_value\'] = $cityId;
$query->query_vars[\'meta_compare\'] = \'=\';

我会得到我的过滤结果。

我想知道，WP是否会接受更多查询变量的meta\\u键/值。。。

我正试图设定一个meta_query 下面是我所做的，但它不起作用。

add_filter( \'parse_query\', \'wpr_manager_filter\' );
function  wpr_manager_filter($query) {
  global $page;
  $current_page = isset( $_GET[\'post_type\'] ) ? $_GET[\'post_type\'] : \'\';

  if ( is_admin()
    && \'properties\' == $current_page
    && \'edit.php\' == $page
  )
  {
    $metaQuery = array();
    if (isset( $_GET[\'city-filter\'] ) && $_GET[\'city-filter\'] != \'-1\')
    {
      $cityId = (int)$_GET[\'city-filter\'];
      $metaQuery[\'relation\'] = \'AND\';
      $metaQuery[] = array(
        \'meta_key\' => \'city\',
        \'meta_value\' => $cityId,
        \'meta_compare\' => \'=\'
      );

      // $query->query_vars[\'meta_key\'] = \'city\';
      // $query->query_vars[\'meta_value\'] = $cityId;
      // $query->query_vars[\'meta_compare\'] = \'=\';
    }
    if (isset( $_GET[\'visibility-filter\'] ) && $_GET[\'visibility-filter\'] != \'-1\')
    {
      $visibility = (int)$_GET[\'visibility-filter\'];
      $metaQuery[2] = array(
        \'meta_key\' => \'visibility\',
        \'meta_value\' => $visibility,
        \'meta_compare\' => \'=\'
      );
    }
    $query->meta_query = $metaQuery;
  }
}

这是漫长的一天，我刚刚开始更加熟悉更深入的WP概念，因此任何能推动我前进并解释我做错了什么的帮助都将不胜感激。

function  wpr_manager_filter($query) {
  global $pagenow;
  global $typenow;

  $current_page = isset( $_GET[\'post_type\'] ) ? $_GET[\'post_type\'] : \'\';

  if ( is_admin()
    && \'properties\' == $typenow
    && \'edit.php\' == $pagenow
  )
  {
    $queryParamsCounter = 0;
    if (isset( $_GET[\'city-filter\'] ) && $_GET[\'city-filter\'] != \'-1\')
    {
      $cityId = (int)$_GET[\'city-filter\'];
      $queryParamsCounter++;
    }
    if (isset( $_GET[\'visibility-filter\'] ) && $_GET[\'visibility-filter\'] != \'-1\')
    {
      $queryParamsCounter++;
      $visibility = (int)$_GET[\'visibility-filter\'];
    }

    $meta_query = array();

    if ($queryParamsCounter > 1) {
      $meta_query[\'relation\'] = \'AND\';
    }

    if (isset($cityId)) {
      $meta_query[] =       array(
        \'key\'     => \'city\',
        \'value\'   => $cityId,
        \'compare\' => \'=\',
        \'type\'    => \'NUMERIC\',
      );
    }
    if (isset($visibility)) {
      $meta_query[] = array(
        \'key\'     => \'visibility\',
        \'value\'   => $visibility,
        \'compare\' => \'=\',
        \'type\'    => \'NUMERIC\',
      );
    }

    $query->set( \'meta_query\', $meta_query);
  }
}

$query->query_vars[\'meta_query\'] = $metaQuery;
