ecshop购物车里商品数量调用方法

涉及到页面：includes/lib_insert.php
在lib_insert.php适当位置加上：
[php]
/**
* 调用购物车商品数目
*/
function insert_cart_info_number()
{
$sql = 'SELECT SUM(goods_number) AS number, SUM(goods_price * goods_number) AS amount' .
' FROM ' . $GLOBALS['ecs']->table('cart') .
" WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
$row = $GLOBALS['db']->GetRow($sql);
if ($row)
{
$number = intval($row['number']);
$amount = floatval($row['amount']);
}
else
{
$number = 0;
$amount = 0;
}
$str = sprintf($number, price_format($amount, false));
return $str;
}
 
[/php]
前台调用：{insert name='cart_info_number'}
