How to make group discount that not affect special products

[sazz12x]

HI community,

I have 10% of Customer group discount. Only thing I want is when i make special discount for specific product (special product) that 10% customer discount to be not applyed.

 

If I have 50% discount on specific product when user is loged as customer discount will be 60% BUT I want to be 50%

 

How to make this? Thanks.

Hi sazz,

 

After checking the code here and there, I believe this is actually simple:

 

edit file /classes/Product.php  (Make Backup!!! Or even better, make an override)

 

 

Find function:

public static function priceCalculation($id_shop, $id_product, $id_product_attribute, $id_country, $id_state, $zipcode, $id_currency,

$id_group, $quantity, $use_tax, $decimals, $only_reduc, $use_reduc, $with_ecotax, &$specific_price, $use_group_reduction,

$id_customer = 0, $use_customer_price = true, $id_cart = 0, $real_quantity = 0)

 

 

In there, you will find the following code (Sample form PS1.6.0.8), and add the red code

 

if ($use_reduc)

  $price -= $specific_price_reduction;

 

// Group reduction

if ($use_group_reduction && !$specific_price) // No group discount for already reduced prices...

{

  $reduction_from_category = GroupReduction::getValueForProduct($id_product, $id_group);

  if ($reduction_from_category !== false)

    $group_reduction = $price * (float)$reduction_from_category;

  else // apply group reduction if there is no group reduction for this category

    $group_reduction = (($reduc = Group::getReductionByIdGroup($id_group)) != 0) ? ($price * $reduc / 100) : 0;

}

else

  $group_reduction = 0;

 

 

I believe this is all. What it does: It checks if the current user is of a group that has group reduction. If the product has NO specific discount, it will apply the general group reduction. if it HAS a reduction already, the group reduction will not be applied.

 

 

Be careful with products that have a lower discount than the general group discount, as the customer may get upset that it doesn't get his/her XX group discount "that she always gets"!

Example:

special discount 5%

VIP group discount 10%

 

the customer of group VIP only gets a 5% discount on that article, as the group discount is not applied.

(To fix this, you could make a special cart rule for that product that applies only to the VIP group, with will then get a 10% discount or so.)

 

Hope this helps,

pascal.

Hello, sorry for the late reply. It works but applies the group discount in product price view.

How to correct this?

[Mr Marius]

Solution works for the product but the total in the cart is calculated as if there is no discount at all. Could someone help me with this?

What should i edit in CartRule.php?
