这个可能要结合书上的过程来看比较好理解
主要是显示方面！书中例子只有第一页，上一页，下一页的链接，我添加了在上下中间显示五个快速跳转链接如下图
代码如下：
<p align="center">
共<b><{$pageInfo.row_total}></b>条记录，
显示第<b><{$pageInfo.page_start}></b>-<b><{$pageInfo.page_end}></b> 条记录
<a href='<{$url}>?p=1'>首页</a>
<{if $pageInfo.prev_page}>
<a href='<{$url}>?p=<{$pageInfo.prev__num}>'>上一页</a>
<{else}>
上一页
<{/if}>
<{if $pageInfo.page_num <= 6}>
<{section name=i loop=$pageInfo.page_num}>
<{if $current_page eq $smarty.section.i.iteration}>
<{$smarty.section.i.iteration}>
<{else}>
<a href ="{$url}?p=<{$smarty.section.i.iteration}>"><{$smarty.section.i.iteration}></a>
<{/if}>
<{/section}>
<{else}>
<{if $current_page < 3}>
<{section name=i loop=5}>
<{if $current_page eq $smarty.section.i.iteration}>
<{$smarty.section.i.iteration}>
<{else}>
<a href ="<{$url}>?p=<{$smarty.section.i.iteration}>"><{$smarty.section.i.iteration}></a>
<{/if}>
<{/section}>
<{elseif $current_page > $pageInfo.page_num - 3}>
<{section name=i start=$pageInfo.page_num-5 loop=$pageInfo.page_num+1}>
<{if $current_page eq $smarty.section.i.index}>
<{$smarty.section.i.index}>
<{else}>
<a href ="<{$url}>?p=<{$smarty.section.i.index}>"><{$smarty.section.i.index}></a>
<{/if}>
<{/section}>
<{else}>
<{section name=i start=$current_page-2 loop=$current_page+3 show=true}>
<{if $current_page eq $smarty.section.i.index}>
<{$smarty.section.i.index}>
<{else}>
<a href ="<{$url}>?p=<{$smarty.section.i.index}>"><{$smarty.section.i.index}></a>
<{/if}>
<{/section}>
<{/if}>
<{/if}>
<{if $pageInfo.next_page}>
<a href='<{$url}>?p=<{$pageInfo.next_page}>'>下一页</a>
<{else}>
下一页
<{/if}>
<a href='<{$url}>?p=<{$pageInfo.page_num}>'>最后一页</a>
当前<b><{$pageInfo.current_page}>/<{$pageInfo.page_num}></b>页
</p>
附上我从书上一字一字码下来分页类，（很辛苦的~）
<?php
class Page{
private $total;
private $page;
private $num;
private $pageNum;
private $offset;
function __construct($total, $page=1, $num=5){
$this->total=$total;
$this->page=$page;
$this->num=$num;
$this->pageNum=$this->getPageNum();
$this->offset=$this->getOffset();
}
private function getPageNum(){
return ceil($this->total/$this->num);
}
private function getNextPage(){
if ($this->page==$this->pageNum)
return false;
else
return $this->page+1;
}
private function getPrevPage(){
if ($this->page==1)
return false;
else
return $this->page-1;
}
private function getOffset(){
return ($this->page-1)*$this->num;
}
private function getStartNum(){
if ($this->total==0)
return 0;
else
return $this->offset+1;
}
private function getEndNum(){
return min($this->offset+$this->num,$this->total);
}
public function getPageInfo(){
$pageInfo=array(
"row_total" =>$this->total,
"row_num" =>$this->num,
"page_num" =>$this->getPageNum(),
"current_page" =>$this->page,
"row_offset" =>$this->getOffset(),
"next_page" =>$this->getNextPage(),
"prev_page" =>$this->getPrevPage(),
"page_start" =>$this->getStartNum(),
"page_end" =>$this->getEndNum()
);
return $pageInfo;
}
}
//end of page_class
总感觉显示的部分代码太多，肯定有办法写到类中的吧，等待发掘了~
