DEDECMS轻松调用当前栏目父级栏目方法详解

本文实例讲述了DEDECMS列表页调用当前栏目父级栏目的方法。分享给大家供大家参考。具体实现方法如下：

修改方法如下

首先找到如下代码:
代码如下: if($type==’top’)

{

$sql = “SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

From `dede_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line “;

}

else if($type==’son’)

{

if($typeid==0) return ”;

$sql = “SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

From `dede_arctype` WHERE reid=’$typeid’ And ishidden<>1 order by sortrank asc limit 0, $line “;

}

else if($type==’self’)

{

if($reid==0) return ”;

$sql = “SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

FROM `dede_arctype` WHERE reid=’$reid’ And ishidden<>1 order by sortrank asc limit 0, $line “;

}

然后将下面代码拷贝到其后面:

代码如下: else if($type==’topone’)

{

if($reid==0) return ”;

$rowR = $dsql->GetOne(“SELECT * FROM `dede_arctype` WHERE id=’$typeid’ “);

$topids = $rowR[‘topid’];

$sql = “SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

FROM `dede_arctype` WHERE reid=’0′ And id=’$topids’ And ishidden<>1 order by sortrank asc limit 0, $line “;

}

else if($type==’fatherlist’)

{

$rowR = $dsql->GetOne(“SELECT * FROM `dede_arctype` WHERE id=’$typeid’ “);

$reid = $rowR[‘reid’];

$rowR = $dsql->GetOne(“SELECT * FROM `dede_arctype` WHERE id=’$reid’ “);

$reid = $rowR[‘reid’];

$sql = “SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

FROM `dede_arctype` WHERE reid=’$reid’ And ishidden<>1 order by sortrank asc limit 0, $line “;

}

说明topone是调用当前目录对应的顶级目录’fatherlist’ 是调用上一级目录,当前目录对应的顶级目录标记:

代码如下: {dede:channel type=’topone’}[field:typename/]{/dede:channel}

这个方法绝对可以,如果想用链接的话,就要[field:typeurl].
