Question

我有unsub.php代码：

<?php 
include("config.inc.php");
$id=$_REQUEST['id'];
$time=$_REQUEST['t'];
$cid=0;
if(isset($_REQUEST['cid']))
$cid=$_REQUEST['cid']

if($cid==0)
mysql_query("update email_advt set unsubstatus=1 where id=$id AND time=$time");
else
{
if($mysql->total(email_advt","id=$id AND time=$time")>0)
mysql_query("delete from ea_em_n_cat where eid=$id AND cid=$cid");
}

<body>
Your email has been successfully unsubscribed from our mailing list. <br>

这个表：

CREATE TABLE IF NOT EXISTS `email_advt` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `email` varchar(250) NOT NULL DEFAULT '',
  `unsubstatus` int(11) NOT NULL DEFAULT '0',
  `time` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;

CREATE TABLE IF NOT EXISTS `ea_em_n_cat` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `eid` int(11) NOT NULL DEFAULT '0',
  `cid` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=7 ;

当访问unsub.php？id = 1＆amp; t = 1360306174＆amp; cid = 0时未显示您的电子邮件已成功取消订阅我们的邮件列表怎么了？访问unsub.php时，unsubstatus未设置为1？id = 1＆amp; t = 1360306174＆amp; cid = 0

Answer 1

使用此查询，您错过了反引号`

mysql_query("update email_advt set `unsubstatus`=1 where `id`=$id AND `time`=$time");

Answer 2

我认为你有错误：

if($mysql->total(email_advt","id=$id AND time=$time")>0)

试

if($mysql->total("email_advt"," id=$id AND time=$time")>0)

虽然我不确定你想要得到什么或total()方法的论据。

Answer 3

如果您使用内置函数作为列名，则需要将其用重音符号括起来。即在您的查询中，您使用的是time列，这是MySQL中的内置函数。

php代码出错，而不是更新日期表
