if ( ! class_exists( 'ZM_Comment_Author_Role_Label' ) ) :
class ZM_Comment_Author_Role_Label {
	public function __construct() {
		add_filter( 'get_comment_author', array( $this, 'zm_get_comment_author_role' ), 10, 3 );
		add_filter( 'get_comment_author_link', array( $this, 'zm_comment_author_role' ) );
	}

	// 获取评论角色
	function zm_get_comment_author_role( $author, $comment_id, $comment ) { 
		$authoremail = get_comment_author_email( $comment); 
		// 检查用户是否注册
		if (email_exists($authoremail)) {
			$commet_user_role = get_user_by( 'email', $authoremail );
			$comment_user_role = $commet_user_role->roles[0];
			// 输出HTML
			$this->comment_user_role = '<span class="comment-author-label comment-author-label-' . $comment_user_role . '">' . ucfirst( $comment_user_role ) . '</span>';
		} else {
			$this->comment_user_role = '';
	}
		return $author;
	}

	// 显示评论角色
	function zm_comment_author_role( $author ) {
		return $author .= $this->comment_user_role;
	}
}
new ZM_Comment_Author_Role_Label;
endif;
