display the catalog price rule discount percentage in the cart

[Martino00]

Hello all. In my PrestaShop 1.6 i'm using two kinds of catalogue discounts. One of 2% another one 12% discount.

The discount percentage is in the catalog price rule.

The users are in a group and the group is connected with the catalog price rule. So the discount is not in the group itself.

 

On my product page (in product.tpl) and on my product-list page (product-list.tpl) i can see the catalog price rule discount percentage.

In the product--list it's showing because of

{if $product.specific_prices.reduction_type == 'percentage'}
<span >-{$product.specific_prices.reduction * 100}%</span>
{/if}

and in the product page it's showing because of

<p id="reduction_percent" 
{if !$product->specificPrice || $product->specificPrice.reduction_type != 'percentage'} style="display:none; "{/if}>
{strip}
<span id="reduction_percent_display">
{if $product->specificPrice && $product->specificPrice.reduction_type == 'percentage'}Uw korting: {$product->specificPrice.reduction*100}%
{/if}
</span>
{/strip}
</p>

My question is...

How can i show this discount percentage in my order-detail.

 

At this moment i have a calculated discount in my order detail.
I have an old price (striped through) and a discount value (so not a percentage) and then the new price.
I can delete it from my shopping-cart-product-line.tpl that's no problem.

 

But i want to display only the discount percentage.

In the database you can find the discount percentage in the ps_specific_price_rule table in the field "reduction"

 

 

Who is able to give me a good start?
