多条件查询结果页面分页的问题
————————构造查询条件REQ
$show_m_dep=trim($_GET['show_m_dep']);
$show_m_pro=trim($_GET['show_m_pro']);
$show_m_con=trim($_GET['show_m_con']);
$show_m_tim1=trim($_GET['show_m_tim1']);
$show_m_tim2=trim($_GET['show_m_tim2']);
$show_m_kin=trim($_GET['show_m_kin']);

echo $_GET[show_m_pro];
$Req="1";
//构造搜索条件1
if($_GET[show_m_dep]=="99"||empty($_GET[show_m_dep]))
{
//如果为空,查询条件不变
}
else
$Req.=" and M_dep = '$_GET[show_m_dep]'";
//构造搜索条件2
if(empty($_GET[show_m_pro]))
{
//如果为空,搜索条件不变
}
else
$Req.=" and M_pro like '%$_GET[show_m_pro]%'";
//条件3
if(empty($_GET[show_m_con]))
{
//如果为空,搜索条件不变
}
else
$Req.=" and M_con like '%$_GET[show_m_con]%'";
//条件4
$temptime="";
if($_GET[show_m_tim1]!="99"&&(!empty($_GET[show_m_tim1])))
{
    $temptime.=$_GET[show_m_tim1];
if($_GET[show_m_tim2]!="99")
{
$temptime.=$_GET[show_m_tim2];
}
$Req.=" and M_tim like '$_GET[temptime]%'";//只有年份或者年份月份都有
}
//条件5
if($_GET[show_m_kin]=="99"||empty($_GET[show_m_kin]))
{
//如果为空,搜索条件不变
}
else
$Req.=" and M_kin like '$_GET[show_m_kin]'";
$_SESSION[Req]=$Req;

—————————分页页面链接
for($i=1;$i{echo "$i ";
}

____________
大致代码如上,因为构造Req的时候从上一个界面get的内容不一定都能用上,所以最后在分页页面链接中Req感觉没法用几个GET的值来拼出来,用SESSION存似乎也不行,点页码跳转时req又变回初始的1了,因此就想请教一下这种时候查询的条件该怎么写才能在分页页面跳转时保存下来?

------解决方案--------------------
你在 url 里传了查询条件,那还要保存做什么?
直接 $_GET['Req'] 用就是了
------解决方案--------------------
直接用url传参就好了,查询条件和页码都用URL进行传参就好了然后取出来,感觉你还是好好分析下自己要实现的这个功能的逻辑比较好。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
