ECSHOP: Display sub-category products on the homepage, and switch category products by clicking on the Tab page_PHP tutorial

开始：    1. 打开调试开关     文件地址：include/cls_template.php 找到 ：     

 function _eval($content)

     函数体第一行增加: echo($content);    改写调试完毕后在注释掉。   2. 修改goods获取函数，以便显示子分类。    文件：include/cls_goods.php 找到函数：function assign_cat_goods, 在 $cat['id']   = $cat_id; 后增加一行:

$cat['cat_id'] = get_child_tree($cat_id);

// 调用子分类信息。

  3.修改模板 cat_goods.lbi ，显示子分类并调用子商品   c0187d15cc6f1a0d2b239b3fc7738f3a

                  市场价： 。 改正如下： 1. 增加当前大分类ID是否有值的判断     增加位置：商品分类模板第一行cat_goods.lbi     代码：

<!--   {<span if</span> not <span is_null</span>(<span $goods_cat</span>.id) || <span $goods_cat</span>.id>0}   -->

2. 修改获取当前ID代码。代码如下：

      <!--   {<span foreach</span> from=<span $goods_cat</span>.cat_id item=rec_cat1 name=f1 <span key</span>=curCat}-->
<span //</span><span 这里循环获取当前商品分类ID，传入获取商品信息集合</span>
       <?<span php 
               </span><span $cid</span> = <span $this</span>->_var['curCat'];  <span //</span><span 改为这个 </span>
            <span $this</span> ->assign('goods_cat_'.<span $cid</span>, assign_cat_goods(<span $cid</span>, 4<span )); //4表示每个分类显示的商品数量，根据实际情况自己修改
            </span><span $this</span>->assign('cat_goods_nf',<span $this</span>->_var['cat_goods_'.<span $cid</span><span ]);
     </span>?>
