DEDECMS列表页调用当前栏目父级栏目的方法

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（文件：include\taglib\channel.lib.php）:

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:

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:

{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].
