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=/"{$preRow['litpic']}/" alt=/"{$preRow['title']}/"/></a> ";
	}
	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=/"{$nextRow['litpic']}/" alt=/"{$nextRow['title']}/"/></a> ";
	}
	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=/"{$preRow['litpic']}/" alt=/"{$preRow['title']}/"/></a> <div>{$preRow['description']}</div> ";
	}
	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=/"{$nextRow['litpic']}/" alt=/"{$nextRow['title']}/"/></a> <div>{$preRow['description']}</div> ";
	}
	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>";
	}
	}
	 
	這樣做的話能顯示文章摘要,但是格式可能會很亂,你可以根據需要增加樣式。
