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:
$count = count($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);
}
esetcookie("retablenum", $count, 0, 1);
esetcookie("rechecktablenum", 0, 0, 1);
