Displaying manufacturer name instead of product name in the viewed products

[PerspectivesMarketin]

Hi,

 

I use PrestaShop 1.6.1.13. I'im trying to display the manufacturer's name instead of the product's name but in vain so far. I managed to do it on the product list and product tempalte files, but somehow the variable doesn't work.

 

Here is the code I'm trying to tweak, from the blockviewed.tpl

 

<a class="product-name" 
href="{$viewedProduct->product_link|escape:'html':'UTF-8'}" 
title="{l s='More about %s' mod='blockviewed' sprintf=[$viewedProduct->name|escape:'html':'UTF-8']}">
{$viewedProduct->name|truncate:25:'...'|escape:'html':'UTF-8'}
</a>

I changed the line before last : 

{$product->manufacturer_name|escape:'html':'UTF-8'}

but I get an "undefined index" error. I understand that it means the variable $product is not called on the blockviewed.tpl

 

My question : how can I call the variable manufacturer_name into the blockviewed file ?

 

Thanks a lot for your time, it is appreciated.
