Fatal Error:call to a member function fpage () on a non-object solution

Fatal Error:call to a member function fpage () on a non-object
Smarty inside me by calling the paging function, page.class.php has been called on the page, and has been instantiated, the specific statement is this:
/* Product List */
function get_product_list ($cat _id)
{
if ($cat _id)
{
$num = 6;
$where = "where classid= ' $cat _id ' and shenhe=1";
$sql 1 = $GLOBALS [' DB ']->query ("select * from". $GLOBALS [' DB ']->table (' product '). $where. ");
$total = $GLOBALS [' db ']->num_rows ($sql 1);
}
Else
{
$num = 6;
$where = "where shenhe=1";
$sql 2= $GLOBALS [' DB ']->query ("select * from". $GLOBALS [' DB ']->table (' product '). $where. ");
$total = $GLOBALS [' db ']->num_rows ($sql 2);
}
$page =new page ($total, $num);
Echo $total;
Exit ();
$sql = "SELECT * from". $GLOBALS [' DB ']->table (' product '). $where. " ORDER BY addtime desc {$page->limit} ";
while ($row = $GLOBALS [' db ']->fetch_array ($sql)]
{
$url = $GLOBALS [' DB ']->rewrite_url (' cpxx_xx ', $row [' ProductID ']);
$product _list[]=array (
"id" = $row [' ProductID '],
"title" = $row [' title '],
"Image" = $row [' Image ']
);
}
return $product _list;
}
/* Initialize data */
$smarty->assign (' Ur_here ', $db->ur_here (' Product_class ', $cat _id));
$smarty->assign (' product_category ', $db->get_product_category (')); Product Show left Category list
$smarty->assign (' Product_list ', get_product_list ($cat _id)); Product List
$smarty->assign (' Page_nav ', $page->fpage (Array (3,4,5,6,7,0,1,2,8)));//Product paginationThis error, to see which great God to give doubts, greatly appreciated ~!
------Solution--------------------
The $page is initialized in the function. That is, he is a local variable, and of course you cannot use it outside of the function.
------Solution--------------------
Returned as a function's return value, for example:
return $product _list;
Change to return Array (
' List ' = $product _list,
' Fpage ' = $page->fpage (Array (3,4,5,6,7,0,1,2,8)),
)
。
------Solution--------------------
The function return value is changed to # # as written.

$smarty->assign (' Product_list ', get_product_list ($cat _id)); Product List
$smarty->assign (' Page_nav ', $page->fpage (Array (3,4,5,6,7,0,1,2,8)));
Switch
$ar = get_product_list ($cat _id);
$smarty->assign (' product_list ', $ar [' list ']); Product List
$smarty->assign (' Page_nav ', $ar [' fpage ']);
------Solution--------------------
function get_product_list ($cat _id)
{
Global $page;Add this sentence.
if ($cat _id)
..........

Other no changes required
