我的任务
分享求助，困扰了我很长时间的分页问题
我的分页定值是是显示正常的，翻页显示正常，但一旦赋值（我希望别人输入日期，可以自动去找那个月的资料），就不行了，第一页是正常的，第二页就开始无法正常显示了，我觉得大概是值没有传到下一页，但我不会改啊~求大家帮忙
经理开始没耐心了~我快疯了，
输入日期页面，scym.php
<html>
<title>日期</title>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
</head>
<body>
<form method="post" action="szym.php">
数据日期格式（如：201206）
<br />
<p>
请输入日期：

表单由 post 方式改为 get 方式
<formmethod="post" action="szym.php">
$rql = $_POST[rq];
改为
$rql = $_GET[rq];
<form
$rql = $_POST[rq];
改为
$rql = $_GET[rq];

把SQL打印出来，就知道了。
echo $sql;
$result=mysql_query($sql);
echo $sql;
$result=mysql_query($sql);
