  WordPress提供了一个函数来从其slug中获取分类信息 .

  $taxonomy_details = get_taxonomy( $slug );
  

  这将作为对象返回分类法详细信息，其中包括分类法的各种标签 . 例如，这里是调用标准类别分类法时返回的对象，例如 get_taxonomy( 'category' );

  stdClass Object
  (
      [labels] => stdClass Object
          (
              [name] => Categories
              [singular_name] => Category
              [search_items] => Search Categories
              [popular_items] => 
              [all_items] => All Categories
              [parent_item] => Parent Category
              [parent_item_colon] => Parent Category:
              [edit_item] => Edit Category
              [view_item] => View Category
              [update_item] => Update Category
              [add_new_item] => Add New Category
              [new_item_name] => New Category Name
              [separate_items_with_commas] => 
              [add_or_remove_items] => 
              [choose_from_most_used] => 
              [not_found] => No categories found.
              [menu_name] => Categories
              [name_admin_bar] => category
          )
  
      [description] => 
      [public] => 1
      [hierarchical] => 1
      [show_ui] => 1
      [show_in_menu] => 1
      [show_in_nav_menus] => 1
      [show_tagcloud] => 1
      [show_in_quick_edit] => 1
      [show_admin_column] => 1
      [meta_box_cb] => post_categories_meta_box
      [rewrite] => Array
          (
              [hierarchical] => 1
              [slug] => category
              [with_front] => 1
              [ep_mask] => 512
          )
  
      [query_var] => category_name
      [update_count_callback] => 
      [_builtin] => 1
      [cap] => stdClass Object
          (
              [manage_terms] => manage_categories
              [edit_terms] => manage_categories
              [delete_terms] => manage_categories
              [assign_terms] => edit_posts
          )
  
      [name] => category
      [object_type] => Array
          (
              [0] => post
          )
  
      [label] => Categories
  )

  由于接受的答案没有回答这个问题，我在这里提供了答案，即使这个问题很老 .

  get_term_by() 的第三个（必需的）参数是分类法本身的名称，因此不能使用此函数 .

  get_taxonomies() 可以't be used either because then you would have to match the entire rewrite array, which you probably don' t可以访问 .

  所以我找到的唯一方法是使用私有数组 $wp_taxonomies ：

  function get_tax_name_from_slug($slug){
    foreach ($wp_taxonomies as $key => $value) {
      if ($value->rewrite['slug'] === $slug){
          return $key;
      }
    }
  }
  

  我真的希望Wordpress能够提供一种方法来实现这一目标，而无需访问其内部数据结构 .

  $args = array(
                      'post_type' => 'awards',
                      'post_status' => 'publish',
                      'posts_per_page' => 4,
                       'orderby' => 'ID',
                       'order' => 'DESC',
                      'tax_query' => array(
                          'relation' => 'AND',
                          array(
                              'taxonomy' => 'awards_categories',
                              'field' => 'slug',
                              'terms' => $award_solution
                          ),
                          array(
                              'taxonomy' => 'year',
                              'field' => 'slug',
                              'terms' => $yearvalue
                          ),
                      )
                  );
  

  我们如何使用wp select查询获取此内容
