Question about voucher

[VIXUS]

I need help on this one...

Does anyone know how can i make one specific voucher that will increase total sum by certain percentage?

[VIXUS]

Nobody knows?

Is this even possible?

I tried adding a voucher with a negative value and it wouldn't let me save it, so I would say that it is not possible using the Back Office. You could try modifying classes/Cart.php and change lines 628-631 from:

/* Secondly applying all vouchers to the correct amount */
foreach ($discounts AS $discount)
   if ($discount->id_discount_type != 3)
       $order_total -= floatval($discount->getValue(sizeof($discounts), $order_total_products, $shipping_fees, $this->id, intval($withTaxes)));

to:

/* Secondly applying all vouchers to the correct amount */
foreach ($discounts AS $discount)
   if ($discount->id_discount_type != 3)
   {
       if ($discount->id == 1)
           $order_total += floatval($discount->getValue(sizeof($discounts), $order_total_products, $shipping_fees, $this->id, intval($withTaxes)));
       else
           $order_total -= floatval($discount->getValue(sizeof($discounts), $order_total_products, $shipping_fees, $this->id, intval($withTaxes)));
   }

where 1 is the id of the voucher you want to be added instead of subtracted.

Darn!!! :shut:

I am on 1.1 and it does not work for me...

this is sample of code that i made, it starts from 595 line:

                /* Secondly applying all vouchers to the correct amount */
               foreach ($discounts AS $discount)
                   if ($discount->id_discount_type != 3)
                   {
                       if ($discount->id == 1)
                           $order_total += floatval($discount->getValue(sizeof($discounts), $order_total_products, $shipping_fees, $this->id));
                       else
                           $order_total -= floatval($discount->getValue(sizeof($discounts), $order_total_products, $shipping_fees, $this->id));
           }
       }
       if ($type == 5) return $shipping_fees;
       if ($type == 6) return $wrapping_fees;
       if ($type == 3) $order_total += $shipping_fees + $wrapping_fees;
       if ($order_total < 0 AND $type != 2) return 0;
       return $order_total;
   }

As soon as i made this change front office dont work at all... HTTP 500 internal server error appears

[VIXUS]

Can someone help me with this?

...is this possible to create?

[rocky]

That's odd. I just tested this code on my v1.2.5 installation and it worked fine. I don't understand why it would cause an error on your front office.

[VIXUS]

Wow, it works... i had one "{" too much.

Can you help me how to fix price display in cart, becouse vaucher ammount is displayed with prefix symbol " - " (like -1.250,00) even do i acutaly am suming those values?

[rocky]

You'll need to change lines 187-188 of shopping-cart.tpl in your theme's directory to:

{if !$priceDisplay || $priceDisplay == 2}{if $discount.id_discount == 1}{convertPrice price=$discount.value_real}{else}{convertPrice price=$discount.value_real*-1}{/if}{if $priceDisplay == 2} {l s='+Tx'}
{/if}{/if}
{if $priceDisplay}{if $discount.id_discount == 1}{convertPrice price=$discount.value_tax_exc}{else}{convertPrice price=$discount.value_tax_exc*-1}{/if}{if $priceDisplay == 2} {l s='-Tx'}{/if}{/if}

and line 82 of modules/blockcart/blockcart.tpl to:

{if $discount.id_discount != 1}-{/if}{if $priceDisplay == 1}{convertPrice price=$discount.value_tax_exc}{else}{convertPrice price=$discount.value_real}{/if}

and line 321 of modules/blockcart/ajax-cart.js to:

$('#bloc_cart_voucher_' + this.id + ' td.price').text(this.id == 1 ? abs(this.price) : this.price);

Hello (sorry for my English)

I have the same problem with negative amount in cart. When all price products gets over a free shipping price, it shows amount with "-".
How can i mak that stops on "0" or show something like "Free shipping is yours"?

Here you can see it: http://abacus.vizz.pl/tmp/screen.png

I am trying to do the samebut instead of negative amount my voucher is negative %. I added a negative % voucher by editing the discount value directly on the database, and it works perfect at first. But when I confirm the order I get this error: (Fatal error (Discount -> value = -12.00)

Any ideas? thanks.
