将变量保留在分页中

这个问题对某些人来说是一个简单的问题，但我无法理解我需要做些什么来解决这个问题。

我有一个网页显示一个带有分页的表格。表上方是会话从上一页传递的一些信息，用户从下拉菜单中选择一个选项。

当用户分页到第二页等时，传递的信息将丢失，可能会对页面刷新执行。

我已经搜索并观看了许多关于Ajax，jquery和php等的教程（超过20个），但我无法理解我在看什么。当我遵循教程时，我无法解释可以解决我的问题的教程。

我想分步指南将是解决此问题的唯一方法，而不是让某人为我做这件事。

我肯定会感谢在这件事上的任何帮助。

我尝试传递到分页及以后的第二页的代码是变量、$brandname、$picked、$pickchek。下面列出了代码的 php 部分。

echo "<div id=firstpick>";
$brandname = $_GET['brandname'];
$picked = $_GET['picked'];
$pickcheck = $_GET['pickcheck'];

$brands =($brandname);
$_SESSION['$brandname']= $brandname;
$pick =($picked);
$_SESSION['$picked']= $pick;
$picker =($pickcheck);
$_SESSION['$pickcheck']=$picker;
echo "</div>";

$tbl_name="pickme";
$adjacents = 3;
$query = "SELECT COUNT(*) as num FROM tirestock";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages["num"];
$targetpage = "connecttest.php";    //your file name  (the name of this file)
$limit = 5;                     //how many items to show per page
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$page=mysql_real_escape_string($page);
if($page)
    $start = ($page - 1) * $limit;  //first item to display on this page
else
    $start = 0;
$sql = "SELECT * FROM tirestock LIMIT $start, $limit";
$result = mysql_query($sql);
if ($page == 0) $page = 1;      /if no page var is given, default to 1.
$prev = $page - 1;              //previous    page is page - 1
$next = $page + 1;                  //next page is page + 1
$lastpage = ceil($total_pages/$limit);//lastpage is = total pages / items per                                           
$lpm1 = $lastpage - 1;              //last page minus 1
