------解决方案--------------------
$page 是在函数中初始化的。也就是他是一个局部变量，当然你不能在函数外使用。
------解决方案--------------------
作为函数的返回值返回，例如：
return $product_list;
改为 return array(
'list'=>$product_list,
'fpage'=>$page->fpage(array(3,4,5,6,7,0,1,2,8)),
)
。
------解决方案--------------------
函数返回值改成#5那样写。
$smarty->assign('product_list',get_product_list($cat_id)); //产品列表
$smarty->assign('page_nav',$page->fpage(array(3,4,5,6,7,0,1,2,8)));
改为：
$ar = get_product_list($cat_id);
$smarty->assign('product_list',$ar['list']); //产品列表
$smarty->assign('page_nav',$ar['fpage']);
------解决方案--------------------
function get_product_list($cat_id)
{
global $page; //加上这句
if($cat_id)
..........
其他无需改动
