朋友们，你们好。
我有一个问题，我正在寻找答案2天了。我想我已经检查了所有10个第一谷歌网页的20个不同的要求。所以，这是它。
I have a custom post type named "Footballer". I have created 2 "Posts" of that CPT, which are "Messi" and "Ronaldo". My permalinks for these 2 footballers are "mysite.com/footballer/messi/" and "mysite.com/footballer/ronaldo/". It is OK for me.
Now, I want to add a child page "about" (or "stats", or anything) to my footballers and I want this page to be available by the link "mysite.com/footballer/messi/about" (just add the child page slug after the cpt post link). Obviously, I want to create a single page "about", not one for every footballer I have, and in this page I would retrieve data for the specific footballer (by functions/shortcodes).
Nota: the cpt and values in this post are fictionnals, I know I would display the about/stats directly in the footballer cpt post. I am just trying to explain what I need -> a generic child page for a cpt, available by "mysite.com/cpt/cptpost/childpage".
我怎么能这么做？这有可能吗？
谢谢你的帮助。

由于Divi不允许，我可以重写我的子页面的网址吗？如果我的子页面网址是"mysite/subpage/？foot = messi"，我可以将其显示为"mysite/footballer/messi/subpage"吗？
我试过这个密码，没有成功

function my_rewrite_url() {

    add_rewrite_tag( '%foot%','([^&]+)' );
    
    add_rewrite_rule(
      'footballer/([^/]+)/subpage',
      'index.php?pagename=subpage&foot=$matches[1]',
      'top'
    );
}
add_action( 'init', 'my_rewrite_url' );
