打開 /include/extend.func.php 在最下面添加

模板里調(diào)用標(biāo)簽寫法

需要哪個(gè)字段，就對應(yīng)的填上字段名即可

獲取頂級欄目相關(guān)信息 {dede:field.typeid function=getToptype(@me,typename)/}

獲取當(dāng)前欄目相關(guān)信息 {dede:field.typeid function=getCurtype(@me,typename)/}

獲取上級欄目相關(guān)信息

{dede:field.typeid function=getRetype(@me,typename)/}

不喜歡添加自定義方法的同學(xué)可以試試這樣

{dede:field.typeid runphp=yes}global $dsql;$row = $dsql->GetOne("SELECT * FROM dede_arctype WHERE id=@me");$reid = "$row[reid]"; $topid = "$row[topid]";if($reid == 0) @me = $row[content];else $row = $dsql->GetOne("SELECT * FROM dede_arctype WHERE id=$topid");@me = $row[content];{/dede:field.typeid}

獲取頂級的是topid

獲取上級的是reid
