Нумерация страниц с фильтром в переполнении стека

Моя проблема заключается в том, что, когда я нажимаю пагинацию, вторая страница снова извлекает все файлы, которые хранятся в базе данных. Это не берет POST Данные, когда я нажимаю на вторую страницу, я хочу, чтобы на второй странице были отфильтрованные результаты. Вот мой код

include 'databaseconnect.php';

// How many adjacent pages should be shown on each side?

$adjacents = 3;
/*
First get total number of rows in data table.
If you have a WHERE clause in your query, make sure you mirror it here.
*/
$bodytypefilter = $_POST['bodytype'];
$query_str = " WHERE ";
$query_str.= "body_type='$bodytypefilter'";
$str.= "&bodytype=" . $bodytypefilter;
$targetpage = $_SERVER["PHP_SELF"] . "?" . $str;
$total_pages = mysql_fetch_array(mysql_query("SELECT count(*) as num from lookdescrip join createdlook ON createdlook.product_id1=lookdescrip.id " . $query_str));
$total_pages = $total_pages[num];
/* Setup vars for query. */
$limit = 1; //how many items to show per page

if (isset($_GET['page'])) {
$page = $_GET['page'];
}
else {

// set proper default value if it was not set

$page = '0';
}

if ($page) $start = ($page - 1) * $limit; //first item to display on this page
else $start = 0;

// if no page var is given, set start to 0

$valid = "";
$valid = true;
$sql1 = "SELECT * from lookdescrip join createdlook ON createdlook.product_id1=lookdescrip.id" . $query_str . " LIMIT $start, $limit";

if ($valid) {
$result1 = mysql_query($sql1);
/* Setup page vars for display. */
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 page, rounded up.
$lpm1 = $lastpage - 1; //last page minus 1
/*
Now we apply our rules and draw the pagination object.
We're actually saving the code to a variable in case we want to draw it more than once.
