织梦二次开发（调用顶级栏目，调用父级栏目名称）

一、调用顶级栏目的栏目信息

　　include\taglib下建立type2.lib.php文件放入以下代码

<?php
/* vim: set expandtab tabstop=4 shiftwidth=4: */

if (!defined('DEDEINC')) exit('Request Error!');
function lib_type2(&$ctag, &$refObj) {
global $dsql, $envs;
$attlist = 'typeid|0';
FillAttsDefault($ctag->CAttribute->Items, $attlist);
extract($ctag->CAttribute->Items, EXTR_SKIP);
$innertext = trim($ctag->GetInnerText());
if ($typeid == 0) {
$typeid = (isset($refObj->TypeLink->TypeInfos['topid']) ? $refObj->TypeLink->TypeInfos['topid'] : $envs['typeid']);
//echo "ssssssssss1".$refObj->TypeLink->TypeInfos['topid'];
//echo "ssssssssss2".$envs['typeid']; exit;
}
//echo "typeid:".$typeid; exit;
//lyy 如果topid==0 就是顶级分类，取当前记录
if($refObj->TypeLink->TypeInfos['topid']==0){
$typeid=$refObj->TypeLink->TypeInfos['id'];
}
//echo "typeid:".$typeid; exit;
if (empty($typeid)) return '';
$row = $dsql->GetOne("SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
FROM `#@__arctype` WHERE id='$typeid'");

if (!is_array($row)) return '';
if (trim($innertext) == '') $innertext = GetSysTemplets("part_type_list.htm");
$dtp = new DedeTagParse();
$dtp->SetNameSpace('field', '[', ']');
$dtp->LoadSource($innertext);
if (!is_array($dtp->CTags)) {
unset($dtp);
return '';
} else {
//lyy 以下getTypeUrl($row[topid]错的，换成 $row['id'] echo $row['id']."sssss";exit;

$row['typelink'] = GetTypeUrl($row['id'], MfTypedir($row['typedir']) , $row['isdefault'], $row['defaultname'], $row['ispart'], $row['namerule2'], $row['siteurl'], $row['sitepath']);

//print_r($row);exit;
foreach ($dtp->CTags as $tagid => $ctag) {
if (isset($row[$ctag->GetName() ])) $dtp->Assign($tagid, $row[$ctag->GetName() ]);
}
$revalue = $dtp->GetResult();
unset($dtp);
return $revalue;
}
} ?>

顶级栏目

以后可以使用{dede:type2} {/dede:type2}来调用顶级栏目的栏目id名称链接等

二、调用父级栏目名称

　　打开include/taglib/type.lib.php 找到

$row['typelink'] = $row['typeurl'] = GetOneTypeUrlA($row);

在其下面增加以下代码

$row['parent_name'] = '';
        $row2= $dsql->GetOne("select topid from dao_arctype where id ='".$row['id']."'");
   $row['topid'] = $row2['topid'];
        
if($row['topid']){
 $row1 = $dsql->GetOne("select typename as parent_name from dao_arctype where id ='".$row['topid']."'");
   $row['parent_name'] = $row1['parent_name'];
  }
  else
     $row['parent_name'] = $row['typename']; //如果时顶级栏目，就显示为该栏目名称

前台模板那调用方法

<!--如果是内容页模板，可以不用指定typeid，直接调用-->
{dede:type}[field:parent_name/]{/dede:type}
 
<!--在首页或者列表页模板，可指定typeid调用-->
{dede:type typeid='1'}[field:parent_name/]{/dede:type}
