您可以使用get_pages() 然后，对于每个页面，使用wp_get_object_terms. 您的代码可能如下所示：

$args = array(
   \'post_type\' => \'board-meeting\',
   \'post_status\' => \'publish\'
 ); 

$pages = get_pages($args); 
if ( ! empty( $pages ) ) {
    echo \'<ul>\';
    foreach($pages as $page){
          $cats = wp_get_object_terms( $page->ID,  \'category\' ); // Array of categories
          $cat = \'\';
          if ( ! empty( $cats ) ) {
              if ( ! is_wp_error( $cats ) ) {
                  $cat = $cats[0]->slug; // slug of 1st category in the array $cats
              }
               // slug of category used as CSS class name for anchor tag
               echo \'<li><a class=\'. $cat.\' href="\' . get_permalink($page-ID) . \'">\' . esc_html( $page->post_title ) . \'</a></li>\'; 
           }
    }
    echo \'</ul>\';
}

我希望这有帮助。
