谈谈dedecms怎样在channel标签中调用栏目描述[field:description/]

只要在include\taglib\channel.lib.php

找到下面黑色代码,加入下面红色代码 description,即可

位置在78行

if($type=='top')
{
      $sql = "SELECT id,typename,description,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 '';
      $sql = "SELECT id,typename,description,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
      From `dede_arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line ";
}
else if($type=='self')
{
      if($reid==0) return '';
      $sql = "SELECT id,typename,description,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
         FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";
}

然后即可调用：
例如：
{dede:channel type='son' typeid='21'}
<p>[field:description/]</p>
{/dede:channel}
