实际主题插件开发中,我们可能需要用到自定义字段custom fields的搜索,并且用来排序,而且是多个。我们这里记录一下代码

    $args = array(
        'post_type' =>  DEBBING_TYPE_SLUG,
        'meta_query'    => array(
            array(
                'relation' => 'AND',
                'status_clause' => array(
                    'key'       => '_debbing_status',
                    'type' => 'NUMERIC', 
                ),
                'order_clause' => array(
                    'key'       => '_debbing_order',
                    'type' => 'NUMERIC',

                ),
            )
            ),
        'orderby' => array(
            'status_clause'       => 'DESC',
            'order_clause'     => 'DESC',
        )
    );
    query_posts($args);
