Wordpress更改相对if子文件夹的绝对路径

Question

我在domain.com/subfolder中有一个开发网站。 当我在编辑器中添加页面链接时，它通常会捕获绝对路径，但我需要它在编辑器中是相对的（例如：/ page-parent / page-child），然后显示domain.com/subfolder/page-parent / page-child在页面上。

First I tried to add a modified filter indicating the site_url(), but it didnt work for me, the path was still absolute when I was adding a page link in the text.
And then I just used WP wp_make_link_relative hook. It partly worked, but the link (in the editor) was still /subfolder/page-parent/page-child.

第一次尝试

add_filter('wp_insert_post_data', function($data) {
    if ($data['post_type'] === 'page') {
        $site_url = site_url();
        $site_url_relative = preg_replace('~^https?://~', '//', $site_url);
        $data['post_content'] = preg_replace("~(<[a-z][^>]+(?:href|src)=\\\\('|\"))$site_url(?=[^\\s'\">]*\\2)~i", "\\1$site_url_relative", $data['post_content']);
    }
    return $data;
});

第二次尝试

add_filter( 'post_link', 'wp_make_link_relative' );       // Normal post link
add_filter( 'post_type_link', 'wp_make_link_relative' );  // Custom post type link
add_filter( 'page_link', 'wp_make_link_relative' );       // Page link
add_filter( 'attachment_link', 'wp_make_link_relative' ); // Attachment link
add_filter( 'get_shortlink', 'wp_make_link_relative' );   // Shortlink

所以我期望链接在编辑器中是/ page-parent / page-child，在前端是完整路径（带有site_url）。 我究竟做错了什么？
