我知道有两种不同类型的自定义帖子类型：-页面帖子。

哪里page 支持子页，以及post 没有。

然而，当我试图在slug中创建一个只有数字的子页面时，wordpress将-2放在后面。示例：

/posttype/父/10-2/

而不是我想要的：

/posttype/父/10/

为什么会这样，我该如何解决？我已经搜索了好几个小时，但我似乎找不到解决方案，除了Wordpress中可能存在的一个限制，它与date permalink系统存在冲突。我没有使用这个系统，但这是真的吗？

编辑，更多信息：没有任何帖子会与我的永久链接冲突。permalink绝对不会被使用。

我通过全新安装wordpress获得了这种行为，并且只有1种自定义帖子类型。wordpress数据库中的帖子只有“parent”和“02”。其中“02”变为“02-2”。

我想知道是否分页/slug/page/02可能是数字slug不被接受的原因？

重要的是要注意，我只得到数字段塞，/父/子/不是问题。

我已经看到了一些关于覆盖过滤器的内容，但这难道不能简单地隐藏问题吗？我宁愿解决它。

我用于注册自定义帖子类型的代码：

    $labels = array(
    \'name\'                => _x( $options[\'euthus_posttype_meervoud\'], \'Post Type General Name\', \'text_domain\' ),
    \'singular_name\'       => _x( $options[\'euthus_posttype\'], \'Post Type Singular Name\', \'text_domain\' ),
    \'menu_name\'           => __( $options[\'euthus_posttype_meervoud\'], \'text_domain\' ),
    \'name_admin_bar\'      => __( $options[\'euthus_posttype_meervoud\'], \'text_domain\' ),
    \'parent_item_colon\'   => __( \'Parent Item:\', \'text_domain\' ),
    \'all_items\'           => __( \'All Items\', \'text_domain\' ),
    \'add_new_item\'        => __( \'Add New Item\', \'text_domain\' ),
    \'add_new\'             => __( \'Add New\', \'text_domain\' ),

    \'not_found_in_trash\'  => __( \'Not found in Trash\', \'text_domain\' ),
);
$rewrite = array(
    \'slug\'                => $options[\'euthus_posttype_baseurl\'],
    \'with_front\'          => true,
    \'pages\'               => false,
    \'feeds\'               => true,
);
$args = array(
    \'label\'               => __( \'euthus_childs\', \'text_domain\' ),
    \'description\'         => __( $options[\'euthus_posttype_meervoud\'], \'text_domain\' ),
    \'labels\'              => $labels,
    \'supports\'            => array( \'title\', \'thumbnail\', \'page-attributes\',),
    \'hierarchical\'        => true,
    \'public\'              => true,
    \'show_ui\'             => true,
    \'show_in_menu\'        => true,
    \'menu_position\'       => 20,
    \'menu_icon\'           => \'dashicons-networking\',
    \'show_in_admin_bar\'   => true,
    \'show_in_nav_menus\'   => true,
    \'can_export\'          => true,

    \'exclude_from_search\' => false,
    \'publicly_queryable\'  => true,
    \'rewrite\'             => $rewrite,
    \'capability_type\'     => \'page\',
);
register_post_type( \'euthus_childs\', $args );

据我所知，“capability\\u type”必须设置为page 而不是post 要允许分层，将其设置为“post”不允许这样做。
