dedecms后台添加新变量删除的功能

织梦dedecms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();
}
?>
