ECSHOP二次开发：ECSHOP首页购物车中商品数量调用

有时候我们需要单独调用购物车中商品的数量，来放在模版中使用。此时就需要用到下边这个函数了。

打开：includes/lib_insert.php文件
在lib_insert.php文件中的适当位置（例如如function insert_cart_info()函数后面）加上：[separator]
[code]
/**
* 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;
}
[/code]

lbi中调用购物车数量：[code]{insert name='cart_info_number'}[/code]

就这么简单！其实就是仿造了一下insert_cart_info()函数
