系統默認的是在dede的上一篇和下一篇的鏈接只顯示標題，但是有時我們希望顯示其他信息，比如文章的摘要。

找到arc.archives.class.php文件，在include目錄下面，然后查找“GetPreNext”這個函數，將

$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 ";

改成

$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 ";


比較一下其實現在只是多了arc.description，這就是文章的摘要，也稱為文章描述。
需要注意的是這里的jcode_archives和jcode_arctype中的jcode_是我表結構的前綴，你需要將這個前綴改成你自己的。

現在我們已經將文章描述從數據庫里面取出來了。下一步將描述顯示在頁面上,顯示連接文字的代碼本來是這樣的，你可以通過查找找到，其實就在上面那段代碼的附近：

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']}&; />";
}
else
{
$this->PreNext['pre'] = "上一篇：沒有了 ";
$this->PreNext['preimg']
="<img src=&;/templets/default/images/nophoto.jpg&;
alt=&;對不起，沒有上一圖集了！&;/>";
}
if(is_array($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']}&; />";
}
else
{
$this->PreNext['next'] = "下一篇：沒有了 ";
$this->PreNext['nextimg'] ="<a href='javascript:void(0)'
alt=&;&;><img src=&;/templets/default/images/nophoto.jpg&;
alt=&;對不起，沒有下一圖集了！&;/></a>";
}
}

現在為了顯示出文章描述，在每一個a標簽之后添加一個div div中包含文章描述(紅色部分)：

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']}&; />}
else
{
$this->PreNext['pre']
= "上一篇：沒有了 ";
$this->PreNext['preimg'] ="<img
src=&;/templets/default/images/nophoto.jpg&;
alt=&;對不起，沒有上一圖集了！&;/>";
}
if(is_array($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']}&; />}
else
{
$this->PreNext['next']
= "下一篇：沒有了 ";
$this->PreNext['nextimg'] ="<a href='javascript:void(0)'
alt=&;&;><img src=&;/templets/default/images/nophoto.jpg&;
alt=&;對不起，沒有下一圖集了！&;/></a>";
}
}
