1、includes\lib_goods.php,在最末尾添加几个function,
2、其中的function get_cat_id_goods_list，是按照虚拟销量调用的

2.打开 category.php，查找：
1 | $smarty->assign('feed_url', ($_CFG['rewrite'] == 1) ? "feed-c$cat_id.xml" : 'feed.php?cat=' . $cat_id); // RSS URL |
后面添加：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | /********************************************************************************************/ //在分类页面调用当前分类以及其二级分类的信心，再在每个分类下调用5个商品 $cats = get_children_tree($cat_id);//获取当前分类信息以及子分类信息 $cat_detail = array(); foreach ($cats as $key => $val) { foreach($cats[$key]['children'] as $_k =>$_v){ $cats[$key]['children'][$_k]['goods_detail'] = get_cat_id_goods_list($_v['id'],5); foreach($cats[$key]['children'][$_k]['goods_detail'] as $_ke =>$_va){ $cats[$key]['children'][$_k]['goods_detail'][$_ke]['thumb_url'] = get_thumb($_va['id']); } } $cat_detail = $cats[$key]['children'];//当前分类下的二级分类及其商品信息 } $smarty->assign('cat_detail', $cat_detail); /********************************************************************************************/ |
然后，在category.dwt 模板中使用以下代码调用即可：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | <!--循环二级分类--> <!--{foreach from=$cat_detail item=cat name=cats_detail}--> <div id=content class="w pt10"> <div class="lzo"> <div class="lzt"> <h2 class="left f16 pl10"><a href="{$cat.url}" target="_blank">{$cat.name}</a></h2> <a class="right gray pr10" href="{$cat.url}" target="_blank">查看更多>></a> </div> <div class="left lzr over"> <div class="w10 left"> <!--{foreach from=$cat.goods_detail item=goods name=goods_detail}--> <dl> <dt><a href="{$goods.url}" target="_blank" title="{$goods.name|escape:html}"><img class="thm" width="220" height="220" src2="{$goods.thumb}"></a></dt> <dd class="thumb"> <!--{foreach from=$goods.thumb_url item=url name=urls}--> <img width="30" height="30" src2="{$url.thumb_url}" data-s="{$url.img_url}"> <!--{/foreach}--> </dd> <dd class="g"><b class="xj"><!-- {if $goods.promote_price neq "￥0.00元"} -->{$goods.promote_price}<!-- {else}-->{$goods.shop_price}<!--{/if}--></b><span class="yj">{$goods.market_price}</span></dd> <dd class="ms fr"><a title="{$goods.name|escape:html}" class="c3 fr" href="{$goods.url}" target="_blank">{$goods.short_name|escape:html}</a> <p title="{$goods.brief|escape:html}" class="gray">{$goods.brief|escape:html}</p> </dd> <dd class="sa"><span>销售:<em>{$goods.sales_volume_base|escape:html}</em></span><!--<span><a href="#" target="_blank">评论:<b>23</b></a></span><a onclick="adCar(this,5503)" title="加入购物车" class="lcar" href="javascript:;"></a>--></dd> </dl> <!--{/foreach}--> </div> </div> <div class="clear"></div> <H3 class="gray fN fr">{$cat.cat_desc}</H3> </div> <p class=lh16></p> </div> <!--{/foreach}--> <!--循环二级分类--> |
