名站网址导航为大驾家提供DedeCMS站点程序站点教程相关的知识,比如织梦程序安装教程,织梦程序系统故障等教程。dedecms网站程序中标签{dede:likearticle }{/dede:likearticle}默认不支持order by 和subway属性,因此对咱们需要用此标签做自定义具体调用,比如用likearticle只具体调用点击高的文章,就实现不了,因此咱们需要对该标签进行修改
源网站文件位置: includetagliblikearticle.lib.php
1.orderby 属性
首先获得标签传递过来的orderby的属性值
$orderby=$ctag->GetAtt('orderby');
在源相关具体代码如下中有这样一组相关具体代码如下

if( empty($arcid) || $byabs==0 ) {
   $orderquery = " order by arc.id desc ";
}
else {
   $orderquery = " order by ABS(arc.id - ".$arcid.") ";
}
likearticle标签默认的排序方式。赋予标签orderby属性那么这段相关具体代码如下就没意义了,先在源码中注释掉这段相关具体代码如下
直接延用默认的order by 子句变量$orderquery,这样sql语句就不用做更改了。
创建新变量 orderquery='';//mysql 查询语句中的order by子句 初始为空
然后根据传递的值做相应的判断,在这里只做一些最常用的值的判断
根据$orderby的值做不同的orderby 查询
if($orderby=='hot' || $orderby=='click') $orderquery = " order by arc.click $orderWay";
else if($orderby == 'sortrank' || $orderby=='pubdate') $orderquery = " order by arc.sortrank $orderWay";
else if($orderby == 'id') $orderquery = " order by arc.id $orderWay";
else if($orderby == 'near') $orderquery = " order by ABS(arc.id - ".$arcid.")";
else if($orderby == 'lastpost') $orderquery = " order by arc.lastpost $orderWay";
else if($orderby == 'scores') $orderquery = " order by arc.scores $orderWay";
else if($orderby == 'rand') $orderquery = " order by rand()";
else if($orderby == 'weight') $orderquery = " order by arc.weight asc";//如果没有特定设置排序则按照权重先排序
else $orderquery = " order by arc.sortrank $orderWay";

ok这样就为likearticle标签增加了完整的order by 属性
2.subday属性(标签获取subday指定的最近几天的数据)
同样先获得subday 的属性值
$subday=$ctag->GetAtt('subday');
然后做时间差计算
if($subday > 0)
   {
    $ntime = gmmktime(0, 0, 0, gmdate('m'), gmdate('d'), gmdate('Y'));
    $limitday = $ntime - ($subday * 24 * 3600);
    $subdaysql = " and arc.senddate > $limitday ";
   }
然后在标签源码的两处sql查询语句中 增加$subdaysql子句判断
第一处为:
$query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule,
           tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath
            from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id
            where arc.arcrank>-1 and ($keyword) $typeid $orderquery limit 0, $row";
修改为:
$query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule,
           tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath
            from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id
            where arc.arcrank>-1 and ($keyword) $typeid $subdaysql $orderquery limit 0, $row";
第二处为:
$query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule,
           tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath
            from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id
           where arc.arcrank>-1 and $typeid $orderquery limit 0, $row";
修改为:
$query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule,
           tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath
            from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id
           where arc.arcrank>-1 and $typeid $subdaysql $orderquery limit 0, $row";
做完以上更改就为likearticle标签增加了subday属性
以下为修改完之后的likearticle.lib.php的完整相关具体代码如下(增加了 orderby 和 subday 属性)
修改之后完整网站文件:
