Dear All,
I have just done it for upselling links in 4 columns and it works with 4.1.10. Here is the code for related_products.tpl
{* $Id: related_products.tpl,v 1.15.2.1 2007/05/02 06:05:39 max Exp $ *}
{if $product_links ne ""}
{capture name=related_products}
{assign var="tmp" value="0"}
{section name=cat_num loop=$product_links}
{if $product_links[num].productid}{assign var="tmp" value="1"}{/if}
{/section}
{section name=num loop=$product_links}
{if %num.first%}
<table border=0 width="100%">
<tr>
{/if}
{if $smarty.section.num.index is div by 4}
</tr><tr valign="top">
{/if}
<td width=25% align=center valign=top class="PListCell";>
<a href="product.php?productid={$product_links[num].productid}" class="ItemsList">{$product_links[num].product}</a>
<br />
<a href="product.php?productid={$product_links[num].productid}">{include file="product_thumbnail.tpl" productid=$product_links[num].productid image_x=$config.Appearance.thumbnail_width product=$product_links[num].product type="T"}<br /><br />{$lng.lbl_see_details}</a>
<br /><br />
<font class="ProductPrice">{$lng.lbl_our_price}: {include file="currency.tpl" value=$product_links[num].taxed_price}</font>
</td>
{if %num.last%}
</tr></table>
{/if}
{/section}
{/capture}
{include file="dialog.tpl" title=$lng.lbl_related_products content=$smarty.capture.related_products extra='width="100%"'}
{else}
{capture name=dialog}
No related products with this product.
