系统默认的是在dede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$query= "Selectarc.id,arc.title,arc.shorttitle,arc.typeid,arc.ismake,arc.senddate,arc.arcrank,arc.money,arc.filename,arc.litpic,t.typedir,t.typename,t.namerule,t.namerule2,t.ispart,t.moresite,t.siteurl,t.sitepathfrom `jcode_archives` arc left join jcode_arctype t on arc.typeid=t.id ";改成$query = "Selectarc.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.sitepathfrom `jcode_archives` arc left join jcode_arctype t on arc.typeid=t.id ";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: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'><imgsrc=\"{$preRow['litpic']}\" />";}else{$this->PreNext['pre'] = "上一篇:没有了 ";$this->PreNext['preimg']="<img src=\"/templ织梦模板免费下裁ets/default/images/nophoto.jpg\"alt=\"对不起,没有上一图集了!\"/>";}if(is_array($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='$mlink'><imgsrc=\"{$nextRow['litpic模板织梦']}\" />";}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>";}}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(红色部分):if(is_array($preRow)){$mlink =GetFileUrl($preRow['id'],$preRow['typeid'],$preRow['senddate'],$preRow['title'],$preRow['织梦模板免费;ismake'],$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='$mlink'><imgsrc=\"{$preRow['litpic']}\" />}else{$this->PreNext['pre']= "上一篇:没有了 ";$this->PreNext['preimg'] ="<imgsrc=\"/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='$mlink'><imgsrc=\"{$nextRow['litpic']}\" />}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>";}}
