dede织梦:tag调用指定多个栏目的TAG标签

例如，我要调用指定的1,2,3这个几个栏目和子栏目的TAG标签出来

{dede:tag row='30' sort='new' getall='1'typeid='1,2,3'}<a href="[field:link/]">[field:tag/]</a>{/dede:tag}

解决方法

打开 /include/taglib/tag.lib.php 找到 ，大概在67行左右

$addsql = " WHERE typeid='$typeid' ";

改成

//指定了多个栏目时
if( preg_match('#,#', $typeid) )
{
	$typeids = explode(',', $typeid);
	foreach($typeids as $ttid) {
		$typeidss[] = GetSonIds($ttid);
	}
	$typeidStr = join(',', $typeidss);
	$typeidss = explode(',', $typeidStr);
	$typeidssok = array_unique($typeidss);
	$typeid = join(',', $typeidssok);
	$addsql = " WHERE typeid IN ($typeid) ";
}
else
{
	$addsql = " WHERE typeid IN (".GetSonIds($typeid).") ";
}

如图
