如何生成自定义帖子类型年份存档重写规则？

Question

好的，在尝试像我通常做的重写一样自己做之后（但这次出于某种原因，没有运气）我找到了这个答案：

Custom post type yearly/ monthly archive

但仍然不适合我。 如果我记录规则，我可以找到正确的，它会被正确写入：

["it/press-release/([0-9]{4})/?$"]=> string(50) "index.php?post_type=press_article&year=$matches[1]"

为了完整起见，登录规则的第一行是（见下面最后一行，没错）：

array(309) {
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})/?$"]=>
  string(87) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&day=$matches[3]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})/feed/(feed|rdf|rss|rss2|atom)/?$"]=>
  string(104) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&day=$matches[3]&feed=$matches[4]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})/(feed|rdf|rss|rss2|atom)/?$"]=>
  string(104) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&day=$matches[3]&feed=$matches[4]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})/page/([0-9]{1,})/?$"]=>
  string(105) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&day=$matches[3]&paged=$matches[4]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/?$"]=>
  string(71) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/feed/(feed|rdf|rss|rss2|atom)/?$"]=>
  string(88) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&feed=$matches[3]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/(feed|rdf|rss|rss2|atom)/?$"]=>
  string(88) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&feed=$matches[3]"
  ["it/press-release/([0-9]{4})/([0-9]{1,2})/page/([0-9]{1,})/?$"]=>
  string(89) "index.php?post_type=press_article&year=$matches[1]&monthnum=$matches[2]&paged=$matches[3]"
  ["it/press-release/([0-9]{4})/?$"]=>
  string(50) "index.php?post_type=press_article&year=$matches[1]"

但还是不行。如果我尝试导航到it/press-release/2016（是的，有那个日期的帖子）我会被重定向到首页。

我必须说几件事：

• 我使用 polylang

• 我的自定义帖子类型是这样注册的：

  $args = array(
     'public' => true,
     'supports' => array('title','editor','page-attributes'),
     'description' => 'Rassegna stampa',
     'labels' => $labels, // omitting here since not relevant
     'rewrite' => array('slug' => pll__('rassegna-stampa')),
     'has_archive' => true,
     'menu_icon' => 'dashicons-media-document'
  );//end args
  
  register_post_type('press_article',$args);
  

有人能发现问题吗？

我在我最近的 WorPress 项目中做了类似的事情，客户希望有基于年份的新闻导航（新闻类别中的帖子）。我使用自定义重写规则来做到这一点。

注册自定义重写规则

function px_generate_rewrite_rules($wp_rewrite)
{
    $new_rules = array(
        '([^/]+)/archive/(\d+)/?$' => 'index.php?category_name=$matches[1]&px_archive_year=$matches[2]'
    );
    $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}
add_action('generate_rewrite_rules', 'px_generate_rewrite_rules');

注册自定义查询变量

function px_query_vars($qvars)
{
    $qvars[] = 'px_archive_year';
    return $qvars;
}
add_filter('query_vars', 'px_query_vars');

添加您的自定义查询

function px_pre_posts($query) 
{

    if( ! is_admin() )
    {
        if( $query->is_main_query() && is_category() )
        {
            set_query_var('date_query', array(
                array(
                    array(
                        'year'  => get_query_var('px_archive_year', date('Y')),
                    )
                )
            ));
            return;
        }
    }
}
add_action('pre_get_posts', 'px_pre_posts');

请记住，如果您更改某些内容，则必须刷新重写规则。完成后删除此代码。

add_action('init', function() {
    flush_rewrite_rules();
});

注意！请注意页面标题。每个页面都应该有一个唯一的标题。
