dedecms后台添加新变量删除的功能

秋天是金灿灿的丰收，秋天是沉甸甸的硕果，秋天是让人满载而归的欢笑和欣喜。

dede后台新建 sys_check.php

<?php
require_once(dirname(__FILE__).'/config.php');
$row = $dsql->GetOne("SELECT * FROM `dede_sysconfig` WHERE aid='$id'");
$info=$row["info"];
if( $action == 'del' )
{
$id = explode("`", $id);
foreach ($id as $var)
{
$query = "delete from `dede_sysconfig` WHERE `aid` = '$var'";
$dsql->ExecuteNoneQuery($query);
}
ShowMsg("已删除变量 $info ","sys_info.php");
exit();
}
?>

dede/templets/sys_info.htm 替换为一下内容 ,53行至111行, 202行, 224行, 226行, 259行至265行为新增内容
