我有一个搜索表单，我想要分页，到目前为止我成功进行搜索和分页但我发现当我按下分页上的下一个按钮或第二页时使用分页它没有从搜索查询中获取数据如何解决？
'if(isset($_POST['butendn']) )

if ($_REQUEST["Category"]<>'') {
$search_Category = " AND Category='".mysql_real_escape_string($_REQUEST["Category"])."'";

}
$targetpage = "pmb.php";
$limit = 10;
$query = "SELECT COUNT(ECRNo) as num FROM ".$SETTINGS['data_table']."";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
$stages = 3;
$page = mysql_escape_string($_GET['page']);
if($page){
$start = ($page - 1) * $limit;
}else{
$start = 0;
}
$search_groupby = "Group by CategoryID,OracleCategory,ProductCode,SalesDate ORDER BY CategoryID,OracleCategory,ProductCode LIMIT $start, $limit ";

这是我的搜索代码，这里是分页代码
if ($page == 0){$page = 1;}
$prev = $page - 1;
$next = $page + 1;
$lastpage = ceil($total_pages/$limit);
$LastPagem1 = $lastpage - 1;
$paginate = '';
if($lastpage > 1)
{
$paginate .= "<ul class='pagination'>";
if ($page > 1){
$paginate.= "<li><a href='$targetpage?page=$prev'>← prev</a></li>";
}else{
$paginate.= "<li><span class='disabled'>← prev</span></li>"; }
if ($lastpage < 7 + ($stages * 2))
{
for ($counter = 1; $counter <= $lastpage; $counter++)
{
if ($counter == $page){
$paginate.= "<li><span class='active'>$counter</span></li>";
}else{
$paginate.= "<li><a href='$targetpage?page=$counter'>$counter</a></li>";}
}
}
elseif($lastpage > 5 + ($stages * 2)) // Enough pages to hide a few?
{
// Beginning only hide later pages
if($page < 1 + ($stages * 2))
{
for ($counter = 1; $counter < 4 + ($stages * 2); $counter++)
{
if ($counter == $page){
$paginate.= "<li><span class='active'>$counter</span></li>";
}else{
$paginate.= "<li><a href='$targetpage?page=$counter'>$counter</a></li>";}
}
$paginate.= "<li><a href='#'>...</a></li>";

以下是一个示例，可以帮助您
<link href=“bootstrap.css” rel=“stylesheet”>
<?php
$dbhost = ‘localhost’;
$dbuser = ‘root’;
$dbpass = ”;
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die (‘Error connecting to mysql’);
$dbname = ‘test’;
$connection = mysql_select_db($dbname);
$limit = 2;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $limit;
$sql = “SELECT * FROM posts ORDER BY title ASC LIMIT $start_from, $limit”;
$rs_result = mysql_query ($sql);
?>
<table class=“table table-bordered table-striped”>
<thead>
<tr>
<th>title</th>
<th>body</th>
</tr>

<tbody>
<?php
while ($row = mysql_fetch_assoc($rs_result)) {
?>
<tr>
<td><? echo $row["title"]; ?></td>
<td><? echo $row["body"]; ?></td>
</tr>
<?php
};
?>
</tbody>
</table>
<?php
$sql = “SELECT COUNT(id) FROM posts”;
$rs_result = mysql_query($sql);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / $limit);
$pagLink = “<div class=’pagination’>”;
for ($i=1; $i<=$total_pages; $i++) {
$pagLink .= “<a href=’index.php?page=”.$i.“‘>”.$i.“</a>”;
