我有两种自定义帖子类型。一个有slu artwork，另一个有slu research-materials。艺术作品帖子的永久链接结构是http://example.com/artwork/artwork-slug，这是预期的，工作正常，我想要的。在post.php页面上，对于任何research-materials帖子类型的帖子，我都有一个自定义字段（通过ACF），其中包含研究材料帖子所关联的艺术作品帖子以及所需的slug研究资料发布。还有一个针对研究材料岗位类型的自定义分类法，它将在研究材料岗位的永久链接结构的构建中发挥作用。永久链接看起来像http://example.com/artwork/related-artwork-slug/research-materials/custom-taxonomy-term/research-materials-slug
这是我到目前为止的代码，但我没有得到我期望的结果......而是我被重定向到艺术品自定义帖子类型，当我应该被重定向到他的研究材料自定义帖子类型单页。
任何帮助表示赞赏。提前谢谢。

After much tinkering I figured it out. There were a lot of small things wrong with the above code and I also had to make use of the index_template hook. Here's the final code:
class RRP{
public static function init(){
// set up custom post types and custom taxonomies
add_action( 'init', 'RRP::build_custom_post_types' );
add_action( 'init', 'RRP::build_custom_taxonomy' );
// set up custom fields
add_action( 'acf/init', 'RRP::register_custom_fields' );
// validate saved value in custom fields
add_filter( 'acf/validate_value', 'RRP::validate_saved_value_in_custom_fields', 10, 4 );
// update related artwork slug
add_filter( 'acf/update_value', 'RRP::update_related_artwork_slug', 10, 3 );
// add the research material type
add_action( 'save_post_research-materials', 'RRP::set_research_material_type' );
// build rewrite rules
add_filter( 'index_template', 'RRP::point_artwork_and_artist_to_single_templates' );
add_action( 'init', 'RRP::rewrite_stuff', 0 );
add_filter( 'query_vars', 'RRP::build_query_vars', 10 );
