问题描述

I have done pagination in my pg_management.php file that displays all records stored in database. 我已经在pg_management.php文件中完成了分页，该文件显示了存储在数据库中的所有记录。 The problem is When I move to next page , the next page is not shown. 问题是当我移至下一页时，不显示下一页。 When i move my pointer over the link, the link is not hovered. 当我将指针移到链接上时，链接不会悬停。

Below is my code for pagination 以下是我的分页代码 

<?php 

    <?php   $tbl_name=$db_prefix."pages";
        $adjacents = 3;
        $query = "SELECT COUNT(*) as num FROM $tbl_name";
        $total_pages = mysql_fetch_array(mysql_query($query));
        $total_pages = $total_pages['nu

    m'];
        $targetpage = "pg_management.php"; 
        $limit = 2; 
        $page = 15;
        if($page) 
            $start = ($page - 1) * $limit;  
            else
            $start = 0;



    $sql = "SELECT page_name, status FROM $tbl_name LIMIT $start, $limit";
            $result = mysql_query($sql);
            if ($page == 0) $page = 1;
            $prev = $page - 1;
            $next = $page + 1;
            $lastpage = ceil($total_pages/$limit);
            $lpm1 = $lastpage - 1;
            $pagination = "";
    if($lastpage > 1)


    {   
            $pagination .= "<div class='pagination'>";

             if ($page > 1) 
                $pagination.= "<a href='$targetpage?page=$prev'>previous</a>";
            else
                $pagination.= "<span class='disabled'>previous</span>"; 

                if ($lastpage < 7 + ($adjacents * 2))

                {   
                for ($counter = 1; $counter <= $lastpage; $counter++)

This is ready to use user defined function to render the pagination links. 准备使用用户定义的功能来呈现分页链接。 

function do_pagination($mainsql,$targeturl)

{ { 

$result = mysql_query($mainsql);
$count = mysql_num_rows($result);
$targetpage = $targeturl;   
$pagecount = $count / 10;
$pagecount = ceil($pagecount);
$end = $pagecount;
$links = "";
$curpage = $_GET['page'];
$start = 1;
$end = $pagecount;

$adjacents = 3;
$total_pages = $pagecount;  

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

/* Setup page vars for display. */

if ($curpage == 0) $curpage = 1;                    //if no page var is given, default to 1.
$prev = $curpage - 1;                           //previous page is page - 1
$next = $curpage + 1;                           //next page is page + 1
$lastpage = $pagecount;             //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1;      
$page = $curpage;
