PHP结合Smarty分页类
<?php

//$conn,$tpl 全局变量 传入 $table是数据表 $where 是条件语句 $order 是ADSC之类的,$pager_size是每页显示数,$pager是当前页
//返回后在摸板里面可以直接使用
<{section name=sec loop=$show}> <{/section}>
数字标签用<{$numlink}>
class my_Pager extends show_Pager
{
function __construct($table,$where,$order,$pager_size,$pager)
{
global $conn;
global $tpl;
$sql="SELECT * FROM `$table` $where order by $order desc";
$nums=$conn->Execute($sql)->RecordCount();
$pager=new show_Pager($nums,$pager_size,$pager);
$show=$conn->SelectLimit($sql,$pager_size,$pager->_offset())->GetAll();
$tpl->assign("numlink",$pager->num_link());//数字标签
$tpl->assign("show",$show);//显示帖子
}
}
