我正在尝试为我的索引页进行分页。索引页面显示来自数据库的数据，其中一些条件来自 url。编辑：这是整个代码：
$town = $_GET['label_town'];
$sub = ucfirst($_GET['label_sub']);
if (isset($_GET['label_town']) === true && isset($_GET['label_sub']) === true) {
$where = "WHERE p.label_town = '$town' AND p.label_sub = '$sub' AND `visible` = 1";
} else if (isset($_GET['label_town']) === true && isset($_GET['label_sub']) === false) {
$where = "WHERE p.label_town = '$town' AND `visible` = 1";
} else {
$where = "WHERE `visible` = 1";
}
$adjacents = 3;
$query = "SELECT COUNT(p.page_id) as num FROM `data_page` AS p $where";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
$targetpage = "index.php";
$limit = 1;
//how many items to show per page
$page = $_GET['page'];
if(isset($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
}
// Example ##1##
$all_page_index = mysql_query("SELECT p.page_id, p.timestamp, p.label_town, p.label_sub, p.ime_nekretnine, p.mjesto, p.cijena_noc, p.krevet_apart, p.broj_apart, p.min_nocenja, p.description, p.visits, i.image_id, i.page_id, i.ext
FROM data_page AS p
LEFT JOIN (
SELECT MAX( image_id ) AS max, page_id
FROM images
GROUP BY page_id
) AS n ON p.page_id = n.page_id
LEFT JOIN images AS i ON i.image_id = n.max
$where
ORDER BY p.page_id DESC
LIMIT $start, $limit");
if ($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.

$pagination = "";
if($lastpage > 1)
{
$pagination .= "<div class=\"pagination\">";
//previous button
if ($page > 1)
$pagination.= "<a href=\"$targetpage?page=$prev\">‹‹ previous</a>";
else
$pagination.= "<span class=\"disabled\">‹‹ previous</span>";
//pages
if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up
{
for ($counter = 1; $counter <= $lastpage; $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
}
elseif($lastpage > 5 + ($adjacents * 2)) //enough pages to hide some
{
//close to beginning; only hide later pages
if($page < 1 + ($adjacents * 2))

<?=$pagination?>
代码没有错误。在 index.php 页面上一切正常，但问题是 $targetpage = "index.php"。当我有条件 url "index.php?label_town=bar&label_sub=apartmani" 并且当我点击分页号浏览器时将我重定向到 index.php?page=somenumber。我尝试使用 $_SERVER['HTTP_REFERER'] 但它加倍 page=somenumber 我也尝试
$targetpage = strtok($_SERVER['QUERY_STRING'], "page");
但这也行不通。
