Question

我做了一个帖子类型，“事件”，它使用自定义字段“Datum”（瑞典语为日期）。我希望此帖子类型的默认视图按此字段排序。

到目前为止，我得到了：

 register_post_type(
                'events',
                array(
                        'labels' => array(
                                'name' => __( 'Arrangemang' ),
                                'singular_name' => __( 'Arrangemang' )
                        ),
                        'supports' => array(
                                'title',
                                'editor',
                                'custom-fields'
                        ),
                        'public' => true,
                        'has_archive' => true,
                        'query_var' => array(
                                'post_type' => 'events',
                                'meta_key' => 'Datum',
                                'orderby' => 'meta_value',
                                'order' => 'ASC',
                        ),
                )
        );

但订购不起作用。如果我在事件的存档页面上运行print_r($wp_query->query_vars);，我会得到：

Array
(
    [post_type] => events
    [error] =>
    [m] => 0
    [p] => 0
    [post_parent] =>
    [subpost] =>
    [subpost_id] =>
    [attachment] =>
    [attachment_id] => 0
    [name] =>
    [static] =>
    [pagename] =>
    [page_id] => 0
    [second] =>
    [minute] =>
    [hour] =>
    [day] => 0
    [monthnum] => 0
    [year] => 0
    [w] => 0
    [category_name] =>
    [tag] =>
    [cat] =>
    [tag_id] =>
    [author_name] =>
    [feed] =>
    [tb] =>
    [paged] => 0
    [comments_popup] =>
    [meta_key] =>
    [meta_value] =>
    [preview] =>
    [s] =>
    [sentence] =>
    [fields] =>
    [category__in] => Array
        (
        )

    [category__not_in] => Array
        (
        )

    [category__and] => Array
        (
        )

    [post__in] => Array
        (
        )

    [post__not_in] => Array
        (
        )

    [tag__in] => Array
        (
        )

    [tag__not_in] => Array
        (
        )

    [tag__and] => Array
        (
        )

    [tag_slug__in] => Array
        (
        )

    [tag_slug__and] => Array
        (
        )

    [meta_query] => Array
        (
        )

    [ignore_sticky_posts] =>
    [suppress_filters] =>
    [cache_results] => 1
    [update_post_term_cache] => 1
    [update_post_meta_cache] => 1
    [posts_per_page] => 100
    [nopaging] =>
    [comments_per_page] => 50
    [no_found_rows] =>
    [order] => DESC
    [orderby] => wp_posts.post_date DESC
)

我是否误解了query_var的{{1}}参数，或者为什么不按照我的要求对列表进行排序？

Answer 1

据我所知，query_var只能是一个布尔值，不处理自定义帖子类型的排序。解决方案是为您的帖子类型创建自定义存档页面并在那里修改循环，以便该自定义帖子类型的存档页面始终按元值排序。

Answer 2

我尝试修改存档页面，但最后只是两次查询帖子，所以如果查询是正确的那样，我联系了“parse_query”以按信息添加订单。

我可能需要稍后更好地定义正确的，但现在它工作正常，并且查询只运行一次。

add_action('parse_request', 'event_sort');

function event_sort($a)
{
   if($a->query_vars AND count($a->query_vars) == 1 AND $a->query_vars['post_type'] == 'events')
   {
      $a->query_vars['meta_key'] = 'Datum';
      $a->query_vars['orderby'] = 'meta_value';
      $a->query_vars['order'] = 'ASC';
   }
}

在我找到parse_request之前，我使用了parse_query：

add_action('parse_query', 'event_sort');

function event_sort($a)
{
   if($a->query AND count($a->query) == 1 AND $a->query['post_type'] == 'events')
   {
      global $wp_query;
      $wp_query->set('meta_key', 'Datum');
      $wp_query->set('orderby', 'meta_value');
      $wp_query->set('order', 'ASC');
   }
}
