在主题中使用the_category（＆＃39;，＆＃39;）时，它会显示类别名称但在短代码中使用它时不起作用。哪个代码用于通过短代码显示类别名称。

Answer 1

试试这段代码：

function categories_list_func( $atts ){
     $categories = get_the_category();

         if($categories) {
            foreach($categories as $category) {
                $output .= '<li class="cat-' . $category->cat_ID . '"><a href="'.get_category_link( $category->term_id ).'" title="' . esc_attr( sprintf( __( "Read more posts from : %s" ), $category->name ) ) . '">'.$category->cat_name.'</a></li>';
            }
            $second_output = trim($output);
          }
          $return_string = '<h4>'.__( "Categories :", "my_site").'</h4><div class="overflow"><ul class="post-categories">' . $second_output . '</ul></div>';

     return $return_string;

    } // END Categories
    add_shortcode( 'categories-list', 'categories_list_func' );
