找到include/global.func.php
開啟上述檔案將下面這個函式放到裡面。注意不要放錯位置,不會放的話放最下面即可!
function subcat1($module = 'phpcms', $catid = NULL, $type = NULL)

{

global $CATEGORY;

$subcat = array();

foreach($CATEGORY as $id=>$cat)

{

  if($id == $catid) $curcat = $cat;

}

if($curcat['parentid'] != 0){

  $curparentarr = split(',',$curcat['arrparentid']);

  $curcatid = $curparentarr[1];

}else{

  $curcatid = $catid;

}

$subcat = subcat($module,$curcatid);

return $subcat;

}

找到子欄目選單模板檔案tag_category_submenu.html
進行如下操作:
將 {php $data = subcat($module, $catid);}
替換為{php $data = subcat1($module, $catid);}
生成呼叫了子欄目選單模板標籤的html,更新快取,ok!
