PHPCMS V9 静态页面判断登录修改方法

phpcms/modules/member/里新建MY_index.php 内容如下：

<?php 
defined('IN_PHPCMS') or exit('No permission resources.');
class MY_index extends index {
    private $times_db;
    public function __construct() {
        parent::__construct();
    }
  public function top_mini() {
    $_username = param::get_cookie('_username');
    $_userid = param::get_cookie('_userid');
    $siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : '';
    $jsoncallback=isset($_GET['jsoncallback']) ? $_GET['jsoncallback'] : '';
    //定义站点id常量
    if (!defined('SITEID')) {
       define('SITEID', $siteid);
    }
    if($_username){
      $res["success"]=1;
      $res["message"]='&nbsp;&nbsp;'.L('hellow').'<a href="'.APP_PATH.'member-account_manage_avatar.html" target="_blank">;<img style="display:inline;vertical-align: middle;padding:1px;width:16px;height:16px;border-radius:100%;border:1px solid #dedede;" src="'.get_memberavatar($_userid,1,30).'" width="16" height="16" onerror="this.src=\''.IMG_PATH.'member/nophoto.gif\'">;</a>;&nbsp;'.get_nickname().' 欢迎回家 <a href="'.APP_PATH.'member-index.html" target="_blank">;'.L('member_center').'</a>; | <a href="'.APP_PATH.'member-fabu.html" target="_top" class="upv_btn">;发布信息</a>; | <a href="'.APP_PATH.'member-logout.html">;'.L('logout').'</a>;';
      $res["message"] = pc_base::load_config('system', 'charset') == 'gbk' ? iconv('utf-8', 'utf-8', $res["message"]) : $res["message"];
      //get_nickname();//,
      }
    else{
      $res["success"]=0;
      }
    if($jsoncallback){
          echo $jsoncallback . "({\"items\":[".json_encode($res)."]})";
    }else{
      echo json_encode($res);
    }
