以下代码适用于帝国CMS6.6版，7.0版不同处在代码注释处已标明。

找到e/admin/ChangeData.php文件

原先的栏目是单选菜单

<select name="classid" id="classid">
<option value="0">所有栏目</option>
<?=$class?>
</select>

改为：

<select name="classid[]" size="12" multiple id="classid[]" style="width:310px">
<option value="0">所有栏目</option>
<?=$class?>
</select>

并且改进了e/admin/DoRehtml.php的代码如下:

复制代码代码如下:
<?php
define('EmpireCMSAdmin', '1');
require ("../../class/connect.php");
require ("../../class/db_sql.php");
require ("../../class/functions.php");
$link = db_connect();
$empire = new mysqlquery();
$editor = 1;
//验证用户
$lur = is_login();
$logininid = $lur['userid'];
$loginin = $lur['username'];
$loginrnd = $lur['rnd'];
$loginlevel = $lur['groupid'];
$loginadminstyleid = $lur['adminstyleid'];
$add = $_GET;
$havehtml = (int)$add['havehtml'];
$tbname = $add['tbname'];
$count = count($tbname);</p><p>// 附加程序开始
if (!is_array($add['classid'])) { //传递非数组值时，在栏目里点击"信息"操作时使用
$add['classid'] = array( $add['classid'] );
}
if ($add['classid'][0] == 0) {
$add['classid'] = array(0);
}
$count1 = count($add['classid']);
for ($m = 0; $m < $count1; $m++) {
$classid = $add[classid][$m];
// 附加程序结束

//刷新所有表
if (!$count) {
$j = 0;
$tsql = $empire->query("select tbname from {$dbtbpre}enewstable order by tid"); // 帝国cms7.0版 这里有个条件为：where intb=0
while ($tr = $empire->fetch($tsql)) {
$tbname[$j] = $tr[tbname];
$j++;
}
$count = count($tbname);
}
