DedeCMS系統(tǒng)默認(rèn)的是在文章的上一篇和下一篇的鏈接只顯示標(biāo)題，但是有時我們希望顯示其他信息，比如文章的摘要。下面給大家介紹一下方法

找到arc.archives.class.php文件，在include目錄下面，然后查找“GetPreNext”這個函數(shù)，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(xiàn)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(jié)構(gòu)的前綴，你需要將這個前綴改成你自己的。

現(xiàn)在我們已經(jīng)將文章描述從數(shù)據(jù)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(xiàn)在為了顯示出文章描述，在每一個a標(biāo)簽之后添加一個div div中包含文章描述：

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(jù)需要增加樣式。
