所以,这么复杂,这么不科学的方法显然不适合我们。
二次开发版
新建一个表,让这个表控制每个文章的数值,我们依靠这个数值来排列,类似添加文章里TAG旁的那个权重一样,我们也给他添加一个权重,只不过这个权重是用来控制文章的排序顺序。
OK,想法有了,那么就开始实现吧,百度了一圈,发现之前也有站长和我相同想法的,不过他们提供的方法是对照旧版DEDE而言,新版不适合他们的代码,不过依葫芦画瓢咱还是可以的。
废话不多说,教程开始
步骤比较多,但是都很简单,无脑操作的,有需要的朋友请认真一步步看下去。
1:首先得给数据库添加一个表,让它来记录这个权重。所以我们进入PHPMYADMIN,找到dede_archives选择结构一栏进入,然后添加表orderid
1、打开 根目录/dede/article_add.php //修改代码文件
搜索找到
$query = "INSERT INTO `dede_archives`(id,typeid,typeid2,sortrank,flag,ismake,channel,arcrank,click,money,title,shorttitle, color,writer,source,litpic,pubdate,senddate,mid,voteid,notpost,description,keywords,filename,dutyadmin,weight) VALUES (‘$arcID‘,‘$typeid‘,‘$typeid2‘,‘$sortrank‘,‘$flag‘,‘$ismake‘,‘$channelid‘,‘$arcrank‘,‘$click‘,‘$money‘, ‘$title‘,‘$shorttitle‘,‘$color‘,‘$writer‘,‘$source‘,‘$litpic‘,‘$pubdate‘,‘$senddate‘, ‘$adminid‘,‘$voteid‘,‘$notpost‘,‘$description‘,‘$keywords‘,‘$filename‘,‘$adminid‘,‘$weight‘);";
修改为
$query = "INSERT INTO `dede_archives`(id,typeid,typeid2,sortrank,flag,ismake,channel,arcrank,click,money,title,shorttitle, color,writer,source,litpic,pubdate,senddate,mid,voteid,notpost,description,keywords,filename,dutyadmin,weight,orderid) VALUES (‘$arcID‘,‘$typeid‘,‘$typeid2‘,‘$sortrank‘,‘$flag‘,‘$ismake‘,‘$channelid‘,‘$arcrank‘,‘$click‘,‘$money‘, ‘$title‘,‘$shorttitle‘,‘$color‘,‘$writer‘,‘$source‘,‘$litpic‘,‘$pubdate‘,‘$senddate‘, ‘$adminid‘,‘$voteid‘,‘$notpost‘,‘$description‘,‘$keywords‘,‘$filename‘,‘$adminid‘,‘$weight‘,‘$orderid‘);";
2、打开dede/article_edit.php //修改代码文件
搜索weight=‘$weight‘在它之后加逗号并回车换行加入以下代码orderid=‘$orderid‘
3、打开dede/templets/article_add.htm //修改模板文件
在适合位置添加以下代码,我是在内容摘要之后添加的。
<table width="100%" border="0" cellspacing="0" cellpadding="0" style="margin-bottom:3px;"> <tbody> <tr> <td width="90" class="bline" height="24"> 排序权重:</td> <td class="bline"><input type=‘text‘ name=‘orderid‘ value=‘0‘ style=‘width:100px;‘ />(请填写数字,越大越靠前)</td> </tr> </tbody> </table>
4、打开dede/include/arc.listview.class.php //修改模版文件
搜索
if
(preg_match(
‘/hot|click|lastpost/‘
,
$orderby
))
修改为
if
(preg_match(
‘/hot|click|orderid|lastpost/‘
,
$orderby
))
5、打开dede/templets/article_edit.html //修改模板文件
在适合位置添加以下代码,我是在文章副栏目之后添加的
<table width="100%" border="0" cellspacing="0" cellpadding="0" style="margin-bottom:3px;"> <tbody> <tr> <td width="90" class="bline" height="24"> 排序权重:</td> <td class="bline"><input type=‘text‘ name=‘orderid‘ value=‘<?php echo $arcRow["orderid"]?>‘ style=‘width:100px;‘ />(请填写数字,越大越靠前)</td> <td></td> </tr> </tbody></table>
6、打开include/arc.listview.class.php //修改代码文件
搜索
else if($orderby=="hot" || $orderby=="click") { $ordersql = " ORDER BY arc.click $orderWay"; }
else if($orderby=="orderid") { $ordersql = " order by arc.orderid $orderWay"; //orderid为dede_archives表里面自己添加的字段 }
7、打开include/taglib/arclist.lib.php //修改代码文件
搜索
else if($orderby == ‘id‘) $ordersql = “ORDER BY arc.id $orderWay”;
在它之后回车增加一行,加入以下代码
else if($orderby == ‘orderid’) $ordersql = “order by arc.orderid $orderWay,arc.id $orderWay”;
{dede:arclist typeid=’1′ row=’10′ titlelen=’60′ orderby=′orderid′}
《你的模版文件代码》
{/dede:arclist}
1.
2.
如果想一次增加加10 $maxOrderid[‘id’] += 10;
3.
4.
打开文件 include\arc.archives.class.php 文件
修改808行的代码如下
$preR = $this->dsql->GetOne("Select id From `#@__archives` where orderid<{$this->Fields[‘orderid‘]} And arcrank>-1 And typeid=‘{$this->Fields[‘typeid‘]}‘ order by orderid desc"); $nextR = $this->dsql->GetOne("Select id From `#@__archives` where orderid>{$this->Fields[‘orderid‘]} And arcrank>-1 And typeid=‘{$this->Fields[‘typeid‘]}‘ order by orderid asc");
这样就上一篇/下一篇链接和自定义排序的链接相符了.
但是问题来了, 旧文档的上一篇,下一篇链接失效, 解决方法是加上一个判断语句
if($this->Fields[‘orderid‘] >=1){ $preR = $this->dsql->GetOne("Select id From `#@__archives` where orderid<{$this->Fields[‘orderid‘]} And arcrank>-1 And typeid=‘{$this->Fields[‘typeid‘]}‘ order by orderid desc"); $nextR = $this->dsql->GetOne("Select id From `#@__archives` where orderid>{$this->Fields[‘orderid‘]} And arcrank>-1 And typeid=‘{$this->Fields[‘typeid‘]}‘ order by orderid asc"); }else{ $preR = $this->dsql->GetOne("Select id From `#@__arctiny` where id<$aid And arcrank>-1 And typeid=‘{$this->Fields[‘typeid‘]}‘ order by id desc"); $nextR = $this->dsql->GetOne("Select id From `#@__arctiny` where id>$aid And arcrank>-1 And typeid=‘{$this->Fields[‘typeid‘]}‘ order by id asc"); }
