在includechannelunit.func.php文件底部添加如下代码:
/*树形栏目补充,获取二级,san级,四级栏目列表/ function getProductTree($typeid) { $linkList = ""; $dsql = new DedeSql(false); $dsql->SetQuery("select ID,typedir,typename,isdefault from dede_arctype where reID = '$typeid' order by sortrank"); $dsql->Execute(); while($row=$dsql->GetObject()) { $typelink = GetTypeUrl($row->id,MfTypedir($row->typedir),$row->isdefault,$row->defaultname,$row->ispart,$row->namerule2,$row->moresite,$row->siteurl,$row->sitepath); $linkList .= "n<div class="firsttype"><a href="$typelink"><b>".$row->typename."</b></a></div>nn"; $linkList .= getSonClass($row->ID); } $dsql->Close(); return $linkList; } //获得小类栏目链接 function getSonClass($parentid) { $linkList = ""; $dsql = new DedeSql(false); $dsql->SetQuery("Select ID,typedir,typename,isdefault From dede_arctype where reID='$parentid' order by sortrank"); $dsql->Execute($parentid); while($row=$dsql->GetObject($parentid)) { $typelink = GetTypeUrl($row->id,MfTypedir($row->typedir),$row->isdefault,$row->defaultname,$row->ispart,$row->namerule2,$row->moresite,$row->siteurl,$row->sitepath); $linkList .= "<li class="secondtype"><a href="$typelink">".$row->typename."</a></li>n"; $linkList .= getSonClass2($row->ID); } return $linkList; } function getSonClass2($parentid) { $linkList = ""; $dsql = new DedeSql(false); $dsql->SetQuery("Select ID,typedir,typename,isdefault From dede_arctype where reID='$parentid' order by sortrank"); $dsql->Execute($parentid); while($row=$dsql->GetObject($parentid)) { $typelink = GetTypeUrl($row->id,MfTypedir($row->typedir),$row->isdefault,$row->defaultname,$row->ispart,$row->namerule2,$row->moresite,$row->siteurl,$row->sitepath); $linkList .= "<li class="thirdtype"><a href="$typelink">".$row->typename."</a></li>n"; $linkList .= getSonClass3($row->ID); } return $linkList; } function getSonClass3($parentid) { $linkList = ""; $dsql = new DedeSql(false); $dsql->SetQuery("Select ID,typedir,typename,isdefault From dede_arctype where reID='$parentid' order by sortrank"); $dsql->Execute($parentid); while($row=$dsql->GetObject($parentid)) { $typelink = GetTypeUrl($row->id,MfTypedir($row->typedir),$row->isdefault,$row->defaultname,$row->ispart,$row->namerule2,$row->moresite,$row->siteurl,$row->sitepath); $linkList .= "<li class="fourthtype"><a href="$typelink">".$row->typename."</a></li>n"; } return $linkList; } /*树形栏目补充*/
2、在模板里用
{dede:channel function='getProductTree(2)'}{/dede:channel}
调用即可。这里getProductTree(2)中的 2 是产品展示的栏目ID。如果你的是其他的,请作相应修改。
