今天来说下如何修改dedecms分页的下一页和上一页的文字和文字长度！

1.首先到include/arc.archives.class.php

加入红色代码，是用来设置默认获取字数的。当前设置为14个中文字符

//获取上一篇，下一篇链接 
function GetPreNext($gtype='',$titlelen=28)

2.再往下找，插入红色部分!即是用截取后的长度赋予$preRow['title2'],那么原始没截取的就是

$preRow['title'] 
$preRow['namerule'],$preRow['typedir'],$preRow['money'],$preRow['filename'],$preRow['moresite'],$preRow['siteurl'],$preRow['sitepath']);
$preRow['title2']=cn_substr($preRow['title'],$titlelen); 
$this->PreNext['pre'] = "上一篇：<a href='$mlink'

3.接下来就很简单了。做鼠标指上后就能显示完整文章标题。（对SEO很有利）

$preRow['namerule'],$preRow['typedir'],$preRow['money'],$preRow['filename'],$preRow['moresite'],$preRow['siteurl'],$preRow['sitepath']); 
$preRow['title2']=cn_substr($preRow['title'],$titlelen); 
$this->PreNext['pre'] = "上一篇：<a href='$mlink' title='{$preRow['title']}'> {$preRow['title2']}</a> ";

4.修改下一篇 如下：

$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],$nextRow['filename'],$nextRow['moresite'],$nextRow['siteurl'],$nextRow['sitepath']); 
$nextRow['title2']=cn_substr($nextRow['title'],$titlelen); 
$this->PreNext['next'] = "下一篇：<a href='$mlink' title='{$nextRow['title']}'>{$nextRow['title2']}</a> ";

如果需要修改文字那我就不说了，直接修改文字即可实现！
