下面是我用来在“概览”小部件中显示CPT的函数

add_action( \'dashboard_glance_items\', \'cpad_at_glance_content_table_end\' );
function cpad_at_glance_content_table_end() {
    $args = array(
        \'public\' => true,
        \'_builtin\' => false
    );
    $output = \'object\';
    $operator = \'and\';

    $post_types = get_post_types( $args, $output, $operator );
    foreach ( $post_types as $post_type ) {
        $num_posts = wp_count_posts( $post_type->name );
        $num = number_format_i18n( $num_posts->publish );
        $text = _n( $post_type->labels->singular_name, $post_type->labels->name, intval( $num_posts->publish ) );
        if ( current_user_can( \'edit_posts\' ) ) {
            $output = \'<a href="edit.php?post_type=\' . $post_type->name . \'">\' . $num . \' \' . $text . \'</a>\';
            echo \'<li class="post-count \' . $post_type->name . \'-count">\' . $output . \'</li>\';
        }
    }
}

对于将来所有向“概览”框添加自定义帖子类型的情况，以下代码在WordPress 4.6.1中适用。这可能对其他人有用。

// Add custom taxonomies and custom post types counts to dashboard
    add_action( \'dashboard_glance_items\', \'cpt_to_at_a_glance\' );
function cpt_to_at_a_glance() {
        // Custom post types counts
        $post_types = get_post_types( array( \'_builtin\' => false ), \'objects\' );
        foreach ( $post_types as $post_type ) {
            $num_posts = wp_count_posts( $post_type->name );
            $num = number_format_i18n( $num_posts->publish );
            $text = _n( $post_type->labels->singular_name, $post_type->labels->name, $num_posts->publish );
            if ( current_user_can( \'edit_posts\' ) ) {
                $num = \'<li class="post-count"><a href="edit.php?post_type=\' . $post_type->name . \'">\' . $num . \' \' . $text . \'</a></li>\';
            }
            echo $num;
        }
    }

在您发布的代码中，我无法真正理解以下内容的意义：

if ( current_user_can( $post_type->cap->edit_posts ) ) {
  $items[] = sprintf( \'%2$s\', $type, $text ) . "\\n";
} else {
  $items[] = sprintf( \'%2$s\', $type, $text ) . "\\n";
}

如果当前用户可以编辑帖子类型（就像WordPress对页面和帖子所做的那样），我想您应该显示帖子列表的链接。

在这种情况下，您的代码变成：

function custom_glance_items( $items = array() ) {
  $post_types = array( \'wrestler\' );
  foreach( $post_types as $type ) {
    if( ! post_type_exists( $type ) ) continue;
    $num_posts = wp_count_posts( $type );
    if( $num_posts ) {
      $published = intval( $num_posts->publish );
      $post_type = get_post_type_object( $type );
      $text = _n(
        \'%s \' . $post_type->labels->singular_name,
        \'%s \' . $post_type->labels->name,
        $published,
        \'your_textdomain\'
      );
      $text = sprintf( $text, number_format_i18n( $published ) );

      // show post type list id user can edit the post type,
      // otherwise just swho the name and the count
      if ( current_user_can( $post_type->cap->edit_posts ) ) {
        $edit_url = add_query_arg( array(\'post_type\' => $type),  admin_url(\'edit.php\') );
        $items[] = sprintf( \'<a href="%s">%s</a>\', $edit_url, $text ) . "\\n";
      } else {
        $items[] = $text . "\\n";
      }

    } // end if( $num_posts )
  } // end foreach
  return $items;
}
