Product variable not displayed on blockbestsellers

[Daniel Patilea]

I'm trying to display the variable date_add :

<p>{$product.date_add}</p>

on the bestsellers block but it does not displaying anything.

Can anybody tell why?

 

Here's the full code:

<div id="leftmodules">

<!-- MODULE Block best sellers -->
<div id="best-sellers">
    <h4 class="top-sellers-h4"><a href="{$link->getPageLink('best-sales.php')}">{l s='Top 5 Sellers' mod='blockbestsellers'} <span>{l s='' mod='blockbestsellers'}</span></a></h4>
    {assign var='nbItemsPerLine' value=5}
    {if $best_sellers|@count > 0}
        <ul class="product_images owl-carousel" id="owl-best">
        
        {foreach from=$best_sellers item=product name=bestSellers}
            <div>
            <li class="{if $smarty.foreach.bestSellers.first}first_item{elseif $smarty.foreach.bestSellers.last}last_item{else}item{/if} {if $smarty.foreach.bestSellers.iteration%$nbItemsPerLine == 0}last_item_of_line{elseif $smarty.foreach.bestSellers.iteration%$nbItemsPerLine == 1} {/if} {if $smarty.foreach.bestSellers.iteration > ($smarty.foreach.bestSellers.total - ($smarty.foreach.bestSellers.total % $nbItemsPerLine))}last_line{/if}">
            <a href="{$product.link}" title="{$product.name|escape:'htmlall':'UTF-8'}"><img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home')}" height="250" width="200" alt="{$product.legend|escape:'htmlall':'UTF-8'}" /></a>
            <h4><a href="{$product.link}" title="{$product.name|truncate:32:'...'|escape:'htmlall':'UTF-8'}">{$product.name|truncate:25:'...'|escape:'htmlall':'UTF-8'}</a></h4>
            <div class="product_desc">{$product.description_short|strip_tags|truncate:60:'.....'}<a href="{$product.link}" title="{l s='More' mod='homefeatured'}">Read More >></a></div>
            <p>{$product->date_add}</p>
            </li>
            </div>            
        {/foreach}
        </ul>
        
    {else}
        <p>{l s='No best sellers at this time' mod='blockbestsellers'}</p>
    {/if}
</div>
<!-- /MODULE Block best sellers -->

</div>

Found the sollution, hope this helps someone .

I saw that this module uses a function called getBestSalesLight(). This function does not select all the informations about products from database so I had to add what I needed in the querry.
