DedeCMS系统默认的是在文章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 href='$mlink'>{$preRow['title']}</a> " ; $ this -> PreNext [ 'preimg' ] = "<a href='$mlink'><img src= " {$preRow['litpic']} " style="line-height: 25.2px; color: rgb(255, 0, 255);">" {$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 href='$mlink'>{$nextRow['title']}</a> " ; $ this -> PreNext [ 'nextimg' ] = "<a href='$mlink'><img src= " {$nextRow['litpic']} " style="line-height: 25.2px; color: rgb(255, 0, 255);">" {$nextRow['title']} " /></a> " ; } 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:
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']} " style="line-height: 25.2px; color: rgb(255, 0, 255);">" {$preRow['title']} " /></a> <div>{$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 href='$mlink'>{$nextRow['title']}</a> <div>{$preRow['description']}</div> " ; $ this -> PreNext [ 'nextimg' ] = "<a href='$mlink'><img src= " {$nextRow['litpic']} " style="line-height: 25.2px; color: rgb(255, 0, 255);">" {$nextRow['title']} " /></a> <div>{$preRow['description']}</div> " ; } 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>" ; } }
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。
