ECSHOP：首页实现显示子分类商品，并实现点击Tab页切换分类商品-php手册-php.cn

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

 function _eval($content)

Copy after login

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);

Copy after login

// 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

class="active" >{$rec_cat.name|escape:html}

//这里循环获取当前商品分类ID，传入获取商品信息集合
$cid = $this->_var['rec_cat1']['id'];
$this ->assign('goods_cat_'.$cid, assign_cat_goods($cid, 4));
$this->assign('cat_goods_nf',$this->_var['cat_goods_'.$cid]);
?>

{$goods.short_name|escape:html}

市场价：

{$goods_cat.name|escape:html}

更多>>

{$goods.short_name|escape:html}

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}   -->

Copy after login

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>?>

Copy after login
