如何修改织梦5.7版上一页下一页文字和长度

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：
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); 
$this->PreNext['pre'] = "上一篇： {$preRow['title2']} "; 

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