为织梦自定义表单添加最后发布时间（适用于多个自定义表单，不用每个点进去看）

ALTER TABLE `dede_diyforms` ADD `mytime` VARCHAR(200) NOT NULL AFTER `public`;

$sql = "Select `diyid`,`name`,`table`,`mytime` From dede_diyforms order by diyid asc";

$query = "INSERT INTO `{$diy->table}` (`id`, `ifcheck` $addvar)  VALUES (NULL, 0 $addvalue); ";

//客户提交同时，更新主表中的时间
$sql= "UPDATE `dede_diyforms` SET mytime = '$mytime' WHERE `dede_diyforms`.table='{$diy->table}'";
        $dsql->ExecuteNoneQuery2($sql);
