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：
1
$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],$nextRow['filename'],$nextRow['moresite'],$nextRow['siteurl'],$nextRow['sitepath']);
2
$nextRow['title2']=cn_substr($nextRow['title'],$titlelen);
3
$this->PreNext['next'] = "下一篇：<a href='$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！
