我创建了一个自定义的帖子类型，并指定了一个重写来将永久链接更改为/old donuts/。请参见下面的代码：

function donut_newsletters_post_type() {

  $labels = array(
    \'name\' => \' Newsletters\',
    \'singular_name\' => \' Newsletter\',
    \'add_new\' => \'Add \',
    \'add_new_item\' => \'Add New \',
    \'edit_item\' => \'Edit \',
    \'new_item\' => \'New \',
    \'view_item\' => \'View \',
    \'search_item\' => \'Search Daily s\',
    \'not_found\' => \'No s found\',
    \'not_found_in_trash\' => \'NO s found in the trash..that would be a sin\'
  );
  $args = array(
    \'labels\' => $labels,
    \'public\' => true,
    \'has_archive\' => false,
    \'publicly_queryable\' => true,
    \'query_var\' => true,
    \'rewrite\' => array(
      \'slug\' => \'old-donuts\'
    ),
    \'capability_type\' => \'post\',
    \'hierarchical\' => false,
    \'supports\' => array(
      \'title\',
      \'editor\',
      \'excerpt\',
      \'thumbnail\'
    ),
    \'taxonomies\' => array(\'post_tags\'),
    \'menu_position\' => 0,
    \'exclude_from_search\' => true,
    \'menu_icon\'   => \'dashicons-email\'
  );

  register_post_type(\'donut_newsletters\', $args);
}

add_action(\'init\', \'donut_newsletters_post_type\');

现在，假设我创建了一个新帖子并将其命名为“test”，永久链接默认为https://thedonut.co/old-donuts/test

I don\'t want this. 什么是我do 希望permalink默认为如下自定义日期结构：

https://thedonut.co/old-donuts/2019-08-24/

我还希望编辑可以修改permalink，这样，如果他/她必须在他们想要发布的前一天创建帖子，他们可以将日值更改为第二天。

请不要将我发送到插件。我已经尝试过自定义post类型的permalinks插件，它可以满足我的需要，但它不允许在发布帖子后修改permalink。

/**

function wpse345850_modify_postdata( $data, $postarr ) {

    if( \'post\' != $data[\'post_type\'] || $postarr[\'ID\'] ) {  // A $_POSTed ID means it\'s an update, not new
        return $data;
    }

    $data[\'post_name\'] = date( \'Y-m-d\' );

    return $data;

}
add_filter( \'wp_insert_post_data\', \'wpse345850_modify_postdata\', 10, 2 );
