我有一个我在其他网站上发现的分页代码。我终于使用我的数据库并分页我的数据了。但是，我不希望脚本列出页面数量，只想显示“下一页”和“上一页”分页链接。我无法理解，但也许你们其中一个人可以：
<?php
include('sqlconnect.php');
include('getdata.php');
mysql_select_db("barter") or die(mysql_error());
// include your code to connect to DB.
$tbl_name="posts"; //your table name
// 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.
*/
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
/* Setup vars for query. */
$targetpage = "fp2.php"; //your file name (the name of this file)
$limit = 3; //how many items to show per page
$page = $_GET['page'];
if($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
/* Get data. */
// Set session variables
$City = $_GET['City'];
$sql = "SELECT * FROM $tbl_name WHERE City = \"$City\" LIMIT $start, $limit";
$result = mysql_query($sql);
/* 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.
*/
$pagination = "";
if($lastpage > 1)
{
$pagination .= "<div class=\"pagination\">";
//previous button
if ($page > 1)
$pagination.= "<a href=\"$targetpage?page=$prev&City=$City\"><img style=\"width:50px; height:50px; clear:all; position:fixed; bottom:30%; right:10;\"src=\"Images/leftarrow.jpg\" /></a>";
else
$pagination.= "<span class=\"disabled\">previous</span>";
//pages

很脏但是应该完成这项工作，评论代码的所有//pages部分：
