<meta http-equiv="Content-Type" c>
<!-- {if $$cat_goods} -->
<div class="sortbox">
<div class="sortbox-title">
<div class="sortbox-title-l"><span><a href="{$goods_cat.url}">{$goods_cat.name|escape:html}</a></span></div>
</div>
<div class="sortbox-content">
<div class="sortbox-product">
<ul>
<!--{foreach from=$cat_goods item=goods}-->
<li>
<div class="photos"> <A href="{$goods.url}"><img src="{$goods.thumb}" alt="{$goods.name|escape:html}" /></A></div>
<div class="name"><A href="{$goods.url}" title="{$goods.name|escape:html}"><span style="color:#4d4d4d; font-family:Tahoma; font-size:14">{$goods.short_name|escape:html}</span></A></div>
<div>
<!-- {if $goods.promote_price neq ""} -->
<span style="font-family:Tahoma; font-size:11px; color:#3ea500;font-weight:bold">{$goods.promote_price}</span>
<!-- {else}-->
<span style="font-family:Tahoma; font-weight:bold; font-size:11px; color:#f50049">{$goods.shop_price}</span>
<!--{/if}-->
</div>
<div class="shop-btn"><A href="javascript:collect({$goods.id})"><img src="../images/sort-collect.gif" alt="" /></A> <A href="javascript:addToCart({$goods.id})"><img src="../images/sort-addcart.gif" alt="" /></A></div>

<!--{/foreach}-->
</ul>
<div class="hack"></div>
