Prestashop – chybná kalkulace skupinové slevy při výběru jiné měny

Při zobrazení detailu produktu a použití skupinové slevy pro jiné měny, se ceny počítají chybně. Je to způsobeno tím, že se cena nepřepočítá dle aktuálního kurzu vybrané měny. Níže uvedenou úpravou docílíte korektního přepočtu.

Ukázka chybného zobrazení a po úpravě:

Soubor pro úpravu: controllers/ProductController.php

Původní kód:

public function formatQuantityDiscounts($specificPrices, $price, $taxRate)
{
foreach ($specificPrices AS $key => &$row)
{
$row['quantity'] = &$row['from_quantity'];
// The price may be directly set
if ($row['price'] != 0)
{
$cur_price = (Product::$_taxCalculationMethod == PS_TAX_EXC ? $row['price'] : $row['price'] * (1 + $taxRate / 100));
if ($row['reduction_type'] == 'amount')
$cur_price = Product::$_taxCalculationMethod == PS_TAX_INC ? $cur_price - $row['reduction'] : $cur_price - ($row['reduction'] / (1 + $taxRate / 100));
else
$cur_price = $cur_price * ( 1 - ($row['reduction']));
$row['real_value'] = $price - $cur_price;
}
else
{
global $cookie;
$id_currency = (int)$cookie->id_currency;
if ($row['reduction_type'] == 'amount')
{
$reduction_amount = $row['reduction'];
if (!$row['id_currency'])
$reduction_amount = Tools::convertPrice($reduction_amount, $id_currency);
$row['real_value'] = Product::$_taxCalculationMethod == PS_TAX_INC ? $reduction_amount : $reduction_amount / (1 + $taxRate / 100);
}
else
{
$row['real_value'] = $row['reduction'] * 100;
}
}
$row['nextQuantity'] = (isset($specificPrices[$key + 1]) ? (int)($specificPrices[$key + 1]['from_quantity']) : -1);
}
return $specificPrices;
}

Do podmínky if ($row[‚price‘] != 0) doplňte kód, viz úprava

Upravený kód:

public function formatQuantityDiscounts($specificPrices, $price, $taxRate)
{
foreach ($specificPrices AS $key => &$row)
{
$row['quantity'] = &$row['from_quantity'];
// The price may be directly set
if ($row['price'] != 0)
{
// upraveno, begin modified
global $cookie;
$id_currency = (int)$cookie->id_currency;
if (($id_currency <> 0) AND ($id_currency <> Configuration::get('PS_CURRENCY_DEFAULT')) )
$cur_price = (Product::$_taxCalculationMethod == PS_TAX_EXC ? Tools::convertPrice($row['price'], $id_currency) : Tools::convertPrice($row['price'], $id_currency) * (1 + $taxRate / 100));
else
// konec úpravy, end
$cur_price = (Product::$_taxCalculationMethod == PS_TAX_EXC ? $row['price'] : $row['price'] * (1 + $taxRate / 100));
