The problem with the calculation of discounts

[vical]

Hi everyone,

 

PrestaShop installed version 1.4.0.17

We work long, there are improvements of source code. We have a problem with the calculation of discounts on goods in the cart. We have made corrections to the module controllers / orderController.php

 

/* Check minimal amount */

$currency = Currency::getCurrency((int)self::$cart->id_currency);

$orderTotal = self::$cart->getOrderTotal();

$existingDiscounts = self::$cart->getDiscounts(true);

if ( ((int)$orderTotal>=10000) )

{

self::$cart->deleteDiscount(1);self::$cart->deleteDiscount(2);self::$cart->deleteDiscount(3);

self::$cart->addDiscount(1);

}

elseif ( ((int)$orderTotal>=7500) and ((int)$orderTotal<10000) )

{

self::$cart->deleteDiscount(1);self::$cart->deleteDiscount(2);self::$cart->deleteDiscount(3);

self::$cart->addDiscount(2);

}

elseif ( ((int)$orderTotal>=5000) and ((int)$orderTotal<7500) )

{

self::$cart->deleteDiscount(1);self::$cart->deleteDiscount(2);self::$cart->deleteDiscount(3);

self::$cart->addDiscount(3);

}

elseif ( ((int)$orderTotal<5000))

{

self::$cart->deleteDiscount(1);self::$cart->deleteDiscount(2);self::$cart->deleteDiscount(3);

}

$orderTotal = self::$cart->getOrderTotal();
