我正在使用CMB2 插件将额外的标题和信息放在帖子上方的我的分类页面上。我可以在后端显示字段，但前端没有显示任何内容？

我用于在后端获取信息的代码：

 add_action( \'cmb2_admin_init\', \'register_taxonomy_metabox\' );
      /**
       * Hook in and add a metabox to add fields to taxonomy terms
       */
      function register_taxonomy_metabox() {
        $prefix = \'cat_headings_\';

        /**
         * Metabox to add fields to categories and tags
         */
        $cmb_term = new_cmb2_box( array(
            \'id\'               => $prefix . \'edit\',
            \'title\'            => esc_html__( \'Category Metabox\', \'cmb2\' ), // Doesn\'t output for term boxes
            \'object_types\'     => array( \'term\' ), // Tells CMB2 to use term_meta vs post_meta
            \'taxonomies\'       => array( \'category\' ), // Tells CMB2 which taxonomies should have these fields
            // \'new_term_section\' => true, // Will display in the "Add New Category" section
        ) );

        $cmb_term->add_field( array(
            \'name\'     => esc_html__( \'Category Headings\', \'cmb2\' ),
            \'desc\'     => esc_html__( \'Sub Heading and Sub Title\', \'cmb2\' ),
            \'id\'       => $prefix . \'cat_info\',
            \'type\'     => \'title\',
            \'on_front\' => false,
        ) );

        $cmb_term->add_field( array(
            \'name\' => esc_html__( \'Category Sub Heading\', \'cmb2\' ),
            \'desc\' => esc_html__( \'Sub Heading\', \'cmb2\' ),
            \'id\'   => $prefix . \'cat-sub-heading\',
            \'type\' => \'text\',
        ) );
      }

以及我用来获取正面信息的代码：

          add_action(\'genesis_before_loop\', \'cat_sub_title\', 5 );
      function cat_sub_title($term_id) {
        $catsubhead = get_term_meta( $term_id, \'cat_headings_cat-sub-heading\', true );
            if ( is_category() ) {
                if ( $catsubhead ) {
                    printf( \'<h2 class="sub-heading">%s</h2>\', $catsubhead );
            }
        }
      }

我已经能够在前面回显一些html，所以我知道我可能对CMB2做了一些错误，我只是不确定是什么？任何人都会非常感谢您的帮助>

谢谢

add_action(\'genesis_before_loop\', \'cat_sub_title\', 5 );
function cat_sub_title() {
    $term_id = get_queried_object()->term_id;
    $catsubhead = get_term_meta( $term_id, \'cat_headings_cat-sub-heading\', true );
        if ( is_category() ) {
            if ( $catsubhead ) {
                printf( \'<h2 class="sub-heading">%s</h2>\', $catsubhead );
        }
    }
}
