给dede文章页面的上一篇下一篇增加文章摘要的功能

你瞧,你绿油油的小草从土里钻了出来。嫩嫩的,它在饱受严冬的考验之后,在严冬它聚集着力量,想在春天到来时,将力量释放出来,它展示出了生命力的顽强,也展现出自己对春天的渴望!在万物最需要水的时候,春雨悄悄地轻轻地到来了。生怕踩到了这些顽强的小精西。春雨打在小草的脸上,轻轻地。小草贪婪的吮吸着春雨,一会儿,春风也来 "凑热闹 "了,春风来为柳树 "梳头 "来了,春风也轻轻地,怕自己的鲁莽把柳树的头发弄断了。
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 = "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']); $this->PreNext['pre'] = "上一篇:<a rel="nofollow noopener noreferrer" href='$mlink'>{$preRow['title']}</a> "; $this->PreNext['preimg'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><img src=\&;{$preRow['litpic']}\&; alt=\&;{$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']); $this->PreNext['next'] = "下一篇:<a rel="nofollow noopener noreferrer" href='$mlink'>{$nextRow['title']}</a> "; $this->PreNext['nextimg'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><img src=\&;{$nextRow['litpic']}\&; alt=\&;{$nextRow['title']}\&;/></a> "; } else { $this->PreNext['next'] = "下一篇:没有了 "; $this->PreNext['nextimg'] ="<a rel="nofollow noopener noreferrer" href='javascript:void(0)' alt=\&;\&;><img src=\&;/templets/default/images/nophoto.jpg\&; alt=\&;对不起,没有下一图集了!\&;/></a>"; } }
现在为了显示出文章描述,在每一个a标签之后添加一个div div中包含文章描述(红色部分):
if(is_array($preRow)) { $mlink = GetFileUrl($preRow['id'],$preRow['typeid'],$preRow['senddate'],$preRow['title'],$preRow['ismake'],$preRow['arcrank'], $preRow['namerule'],$preRow['typedir'],$preRow['money'],$preRow['filename'],$preRow['moresite'],$preRow['siteurl'],$preRow['sitepath']); $this->PreNext['pre'] = "上一篇:<a rel="nofollow noopener noreferrer" href='$mlink'>{$preRow['title']}</a><div>{$preRow['description']}</div>"; $this->PreNext['preimg'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><img src=\&;{$preRow['litpic']}\&; alt=\&;{$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']); $this->PreNext['next'] = "下一篇:<a rel="nofollow noopener noreferrer" href='$mlink'>{$nextRow['title']}</a><div>{$preRow['description']}</div>"; $this->PreNext['nextimg'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><img src=\&;{$nextRow['litpic']}\&; alt=\&;{$nextRow['title']}\&;/></a><div>{$preRow['description']}</div>"; } else { $this->PreNext['next'] = "下一篇:没有了 "; $this->PreNext['nextimg'] ="<a rel="nofollow noopener noreferrer" href='javascript:void(0)' alt=\&;\&;><img src=\&;/templets/default/images/nophoto.jpg\&; alt=\&;对不起,没有下一图集了!\&;/></a>"; } }
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。

本文给dede文章页面的上一篇下一篇增加文章摘要的功能到此结束。大胆自已地表现自已,别人无理由轻视你。小编再次感谢大家对我们的支持!
