Put the product reduction in the thumbnail

[marie12]

I would like to display the reduction for the product on the tumbnail (list of product thumbnails, in the categorie page), and not only in the product page.

How to do ?

I tried to put these lines (from the product.tpl) in the vignette.tpl :

{if $product->specificPrice AND $product->specificPrice.reduction_type == 'percentage'}

<p id="reduction_percent"><span id="reduction_percent_display">-{$product->specificPrice.reduction*100}%</span></p>

{/if}

 

But it doesn' work : I see only "-0%", even if my product has got a reduction (that displays fine on the product page)...

 

An idea ?
