Yoast确实有一个过滤器供您使用。请参见此处：https://gist.github.com/jmcclellan/b2d97ffee0e924e28fa1

我使用它向自定义帖子类型添加“父”页面。我们想使用页面作为我们的类别着陆器，并将自定义帖子类型作为子级。默认情况下，Yoast不会输出父页面slug，因为在技术上没有真正的关系，所以我们使用此函数来覆盖和拼接每个自定义post类型的父slug。您应该能够根据需要修改此解决方案：

add_filter("wpseo_breadcrumb_links", "wpse_100012_override_yoast_breadcrumb_trail");

function wpse_100012_override_yoast_breadcrumb_trail($links)
{
    $post_type = get_post_type();

    if ($post_type === \'claims\') {
        $breadcrumb[] = array(
            \'url\' => \'/claim\',
            \'text\' => \'claim\'
        );
        array_splice($links, 1, -3, $breadcrumb);
    }
    return $links;
}

#breadcrumbs {
    text-transform: lowercase;
}        

事实证明，我今天确实需要这样做，所以我继续写了一个页面解决方案。除了CPT之外，我不使用POST，但只要稍加修改，这也可以用于POST。我留下了我之前的答案，因为它确实提供了一种可能足以满足某些用途的解决方案。

add_filter(\'wpseo_breadcrumb_links\', \'wpse350538_customize_yoast_breadcrumbs\');

function wpse350538_customize_yoast_breadcrumbs($links)
{
    //get current page slug and make it pretty
    $current_page = sanitize_post($GLOBALS[\'wp_the_query\']->get_queried_object());
    $slug = $current_page->post_name;
    $slug_pretty = str_replace(\'-\', \' \', $slug);

    if (is_page()) {
        //this page has ancestors
        if ($current_page->post_parent) {
            //set the first breadcrumb to homepage
            $links = array(
                0 => array(
                    \'url\' => get_home_url(),
                    \'text\' => \'home\'
                )
            );
            //get a list of parent pages, loop through them and add to link array
            $parents = get_post_ancestors($current_page->ID);
            foreach ($parents as $parent) {
                $id = get_post_field(\'ID\', $parent);
                //make sure we don\'t add the current page twice
                if ($id !== $current_page->ID) {
                    //get parent slug and make it pretty
                    $parent_slug = get_post_field(\'post_name\', $current_page->post_parent);
                    $links[] = array(
                        \'url\' => get_permalink($id),
                        \'text\' => str_replace(\'-\', \' \', $parent_slug)
                    );
                }

            }
            //lastly, add current page to link array
            $links[] = array(
                \'url\' => $slug,
                \'text\' => $slug_pretty
            );

        } else {
            // this page is top level so we just use the slug and make it pretty
            $links = array(
                0 => array(
                    \'url\' => get_home_url(),
                    \'text\' => \'home\'
                ),
                1 => array(
                    \'url\' => $slug,
                    \'text\' => $slug_pretty
                )
            );
        }

    }

    return $links;
