任意页面动态调用购物车数量，不用刷新数据。 同时适用于帝国CMS6.6、7.0 
新建一个buycarjs.php文件放在/e/shopsys/buycar/下，代码如下： <?php
require("../../class/connect.php");
require("../../class/q_functions.php");
require("../../class/db_sql.php");
require("../../data/dbcache/class.php");
eCheckCloseMods('shop');//关闭模块
$link=db_connect();
$empire=new mysqlquery();
$editor=1;
$buycar=getcvar('mybuycar');
$record="!";
$r=explode($record,$buycar);
$count=count($r)-1;
?>
document.write(" <?=$count?> ");模板页面调用代码： <a href="/e/ShopSys/buycar/" target="_blank">购物车<script
src="/e/ShopSys/buycar/buycarjs.php"></script>件</a>
