在DedeCMS中的文章页面的上一篇下一篇链接处增加文章摘要的方法

DedeCMS系统默认的是在文章的上一篇和下一篇的链接只显示标题，但是有时我们希望显示其他信息，比如文章的摘要。 
找到arc.archives.class.php文件，在include目录下面，然后查找“GetPreNext”这个函数，将
<pre class="sh_javascript sh_sourceCode" name="code" style='margin: 8px; padding: 3px; outline: none; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; width: 600px; line-height: 22px; clear: both; font-size: 14px; border-color: rgb(187, 187, 187); border-width: 1px 1px 1px 5px; border-style: dashed dashed dashed solid; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-family: Consolas, Monaco, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; word-wrap: break-word; white-space: pre-wrap; color: rgb(0, 0, 0); text-size-adjust: auto;'>
$query
= "Select 
arc.id,arc.title,arc.shorttitle,arc.typeid,arc.ismake,arc.senddate,arc.arcrank,arc.money,arc.filename,arc.litpic, 
t.typedir,t.typename,t.namerule,t.namerule2,t.ispart,t.moresite,t.siteurl,t.sitepath 
from `jcode_archives` arc left join jcode_arctype t on arc.typeid=t.id ";</pre>

　　改成：
<pre class="sh_javascript sh_sourceCode" name="code" style='margin: 8px; padding: 3px; outline: none; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; width: 600px; line-height: 22px; clear: both; font-size: 14px; border-color: rgb(187, 187, 187); border-width: 1px 1px 1px 5px; border-style: dashed dashed dashed solid; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-family: Consolas, Monaco, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; word-wrap: break-word; white-space: pre-wrap; color: rgb(0, 0, 0); text-size-adjust: auto;'>
$query = "Select 
arc.id,arc.title,arc.shorttitle,arc.typeid,arc.ismake,arc.senddate,arc.arcrank,arc.money,arc.filename,arc.litpic, 
arc.description,t.typedir,t.typename,t.namerule,t.namerule2,t.ispart,t.moresite,t.siteurl,t.sitepath 
from `jcode_archives` arc left join jcode_arctype t on arc.typeid=t.id ";</pre>

　　比较一下其实现在只是多了arc.description，这就是文章的摘要，也称为文章描述。

　　需要注意的是这里的jcode_archives和jcode_arctype中的jcode_是我表结构的前缀，你需要将这个前缀改成你自己的。

　　现在我们已经将文章描述从数据库里面取出来了。下一步将描述显示在页面上，显示连接文字的代码本来是这样的，你可以通过查找找到，其实就在上面那段代码的附近：
<pre class="sh_javascript sh_sourceCode" name="code" style='margin: 8px; padding: 3px; outline: none; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; width: 600px; line-height: 22px; clear: both; font-size: 14px; border-color: rgb(187, 187, 187); border-width: 1px 1px 1px 5px; border-style: dashed dashed dashed solid; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-family: Consolas, Monaco, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; word-wrap: break-word; white-space: pre-wrap; color: rgb(0, 0, 0); text-size-adjust: auto;'>
if(is_array($preRow))
{
$mlink =
GetFileUrl($preRow['id'],$preRow['typeid'],$preRow['senddate'],$preRow['title'],$preRow['ismake'],$preRow['arcrank'],
$preRow['namerule'],$preRow['typedir'],$preRow['money'],$preRow['filename'],$preRow['moresite'],$preRow['siteurl'],$preRow['sitepath']);
$this->PreNext['pre']
= "上一篇：<a href='$mlink'>{$preRow['title']}</a> 
";
$this->PreNext['preimg'] = "<a href='$mlink'><img 
src="{$preRow['litpic']}">"{$preRow['title']}"/></a> 
";
}
else
{
$this->PreNext['pre'] = "上一篇：没有了 ";
$this->PreNext['preimg']
="<img src="/templets/default/images/nophoto.jpg" 
alt="对不起，没有上一图集了！"/>";
}
if(is_array($nextRow))
{
$mlink =
GetFileUrl($nextRow['id'],$nextRow['typeid'],$nextRow['senddate'],$nextRow['title'],$nextRow['ismake'],$nextRow['arcrank'],
$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],$nextRow['filename'],$nextRow['moresite'],$nextRow['siteurl'],$nextRow['sitepath']);
$this->PreNext['next']
= "下一篇：<a href='$mlink'>{$nextRow['title']}</a> 
";
$this->PreNext['nextimg'] = "<a href='$mlink'><img 
src="{$nextRow['litpic']}">"{$nextRow['title']}"/></a> 
";
}
else
{
$this->PreNext['next'] = "下一篇：没有了 ";
$this->PreNext['nextimg'] ="<a href='javascript:void(0)' 
alt=""><img src="/templets/default/images/nophoto.jpg" 
alt="对不起，没有下一图集了！"/></a>";
}
}</pre>

　　现在为了显示出文章描述，在每一个a标签之后添加一个div div中包含文章描述：
<pre class="sh_javascript sh_sourceCode" name="code" style='margin: 8px; padding: 3px; outline: none; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; width: 600px; line-height: 22px; clear: both; font-size: 14px; border-color: rgb(187, 187, 187); border-width: 1px 1px 1px 5px; border-style: dashed dashed dashed solid; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-family: Consolas, Monaco, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; word-wrap: break-word; white-space: pre-wrap; color: rgb(0, 0, 0); text-size-adjust: auto;'>
if(is_array($preRow))
{
$mlink =
GetFileUrl($preRow['id'],$preRow['typeid'],$preRow['senddate'],$preRow['title'],$preRow['ismake'],$preRow['arcrank'],
$preRow['namerule'],$preRow['typedir'],$preRow['money'],$preRow['filename'],$preRow['moresite'],$preRow['siteurl'],$preRow['sitepath']);
$this->PreNext['pre']
= "上一篇：<a href='$mlink'>{$preRow['title']}</a> <div>{$preRow['description']}</div> 
";
$this->PreNext['preimg'] = "<a href='$mlink'><img 
src="{$preRow['litpic']}">"{$preRow['title']}"/></a> <div>{$preRow['description']}</div> ";
}
else
{
$this->PreNext['pre']
= "上一篇：没有了 ";
$this->PreNext['preimg'] ="<img 
src="/templets/default/images/nophoto.jpg" 
alt="对不起，没有上一图集了！"/>";
}
if(is_array($nextRow))
{
$mlink =
GetFileUrl($nextRow['id'],$nextRow['typeid'],$nextRow['senddate'],$nextRow['title'],$nextRow['ismake'],$nextRow['arcrank'],
$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],$nextRow['filename'],$nextRow['moresite'],$nextRow['siteurl'],$nextRow['sitepath']);
$this->PreNext['next']
= "下一篇：<a href='$mlink'>{$nextRow['title']}</a> <div>{$preRow['description']}</div> 
";
$this->PreNext['nextimg'] = "<a href='$mlink'><img 
src="{$nextRow['litpic']}">"{$nextRow['title']}"/></a> <div>{$preRow['description']}</div> ";
}
else
{
$this->PreNext['next']
= "下一篇：没有了 ";
$this->PreNext['nextimg'] ="<a href='javascript:void(0)' 
alt=""><img src="/templets/default/images/nophoto.jpg" 
alt="对不起，没有下一图集了！"/></a>";
}
}</pre>

　　这样做的话能显示文章摘要，但是格式可能会很乱，你可以根据需要增加样式。
