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:
复制代码代码如下:if($type=='top')
{
      $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
      From `dede_arctype` WHERE reid=0 And ishidden1 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 ishidden1 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 ishidden1 order by sortrank asc limit 0, $line ";
}
然后将下面代码拷贝到其后面:
复制代码代码如下:else if($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 ishidden1 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 ishidden1 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:
复制代码代码如下:{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].
希望本文所述对大家的dedecms建站有所帮助。
