自定义 Post 类型和分类法使用相同的 slug 和重写

Question

这是我第一次尝试使用 WordPress 重写规则，所以请多多包涵。问题是我添加到投资组合中的所有项目都有多个类别。我想在显示投资组合帖子时从 url 中删除类别。

site.com/portfolio -> 作品

site.com/portfolio/category/ -> 作品

site.com/portfolio/category/post-added-to-portfolio/ -> 可以，但我不想这样

site.com/portfolio/post-added-to-portfolio/ -> 不起作用，但应该

/* Post Type: Portfolio */
$labels = array(
    "name" => __( "Portfolio", "" ),
    "singular_name" => __( "Portfolio", "" ),
);
$args = array(
    "label" => __( "Portfolio", "" ),
    "labels" => $labels,
    "description" => "",
    "public" => true,
    "publicly_queryable" => true,
    "show_ui" => true,
    "show_in_rest" => false,
    "rest_base" => "",

    "rewrite" => array( "slug" => "portfolio", "with_front" => true ),
    "query_var" => true,
    "supports" => array( "title", "editor" ),
    "taxonomies" => array( "services" ),
);
register_post_type( "portfolio", $args );   

/* Taxonomy: Services */
$labels = array(
    "name" => __( "Services", "" ),
    "singular_name" => __( "Service", "" ),
);
$args = array(
    "label" => __( "Services", "" ),
    "labels" => $labels,
    "public" => true,
    "hierarchical" => true,
    "label" => "Services",

    "show_in_quick_edit" => false,
);
register_taxonomy( "services", array( "portfolio" ), $args );

// handle redirects for taxonomy
add_action('generate_rewrite_rules', 'generate_taxonomy_rewrite_rules');

  $rules = array();
  $post_types = get_post_types( array( 'name' => 'portfolio', 'public' => true, '_builtin' => false ), 'objects' );
  $taxonomies = get_taxonomies( array( 'name' => 'services', 'public' => true, '_builtin' => false ), 'objects' );
  foreach ( $post_types as $post_type ) {
    $post_type_name = $post_type->name;
    $post_type_slug = $post_type->rewrite['slug'];
    foreach ( $taxonomies as $taxonomy ) {
      if ( $taxonomy->object_type[0] == $post_type_name ) {
        $terms = get_categories( array( 'type' => $post_type_name, 'taxonomy' => $taxonomy->name, 'hide_empty' => 0 ) );
        foreach ( $terms as $term ) {
          $rules[$post_type_slug . '/' . $term->slug . '/?$'] = 'index.php?' . $term->taxonomy . '=' . $term->slug;
          $rules[$post_type_slug . '/' . $term->slug . '/page/?([0-9]{1,})/?$'] = 'index.php?' . $term->taxonomy . '=' . $term->slug . '&paged=' . $wp_rewrite->preg_index( 1 );
        }
      }
    }
  }
  $wp_rewrite->rules = $rules + $wp_rewrite->rules;
}

经过一周的努力，我终于解决了这个问题。我将 post 类型保持原样。我用以下内容替换了 generate_rewrite_rules 函数。

add_filter('request', 'setTermRequest', 1, 1 );
function setTermRequest($query){
    $tax_name = 'services';
    if( $query['attachment'] ) :
        $include_children = true;
        $name = $query['attachment'];
    else:
        $include_children = false;
        $name = $query['name'];
    endif;
    $term = get_term_by('slug', $name, $tax_name); // get the current term to make sure it exists
    if (isset($name) && $term && !is_wp_error($term)): // check it here
        if( $include_children ) {
            unset($query['attachment']);
            $parent = $term->parent;
            while( $parent ) {
                $parent_term = get_term( $parent, $tax_name);
                $name = $parent_term->slug . '/' . $name;
                $parent = $parent_term->parent;
            }
        } else { unset($query['name']); }
        switch( $tax_name ):
            case 'category':{
                $query['category_name'] = $name; // for categories
                break;
            }
            case 'post_tag':{
                $query['tag'] = $name; // for post tags
                break;
            }
            default:{
                $query[$tax_name] = $name; // for another taxonomies
                break;
            }
        endswitch;
    endif;
    return $query;
}
add_filter( 'term_link', 'writeTermPerm', 10, 3 );
function writeTermPerm( $url, $term, $taxonomy ){
    $taxonomy_name = 'services';
    $taxonomy_slug = 'services';
    if ( strpos($url, $taxonomy_slug) === FALSE || $taxonomy != $taxonomy_name ) return $url;
    $url = str_replace('/'.$taxonomy_slug, '/portfolio', $url);
    return $url;
}

修复 url 结构后，我将以下代码添加到我的分类法-services.php 文档中，以便在一个文件中控制整个系统。

locate_template( 'archive-portfolio.php', true );
