ECTouch是国内市面上唯一开源的ECSHOP移动商城系统，为广大电商以最低的成本快速搭建移动商城。最近最一商城实例，手机版首页需要调用指定分类下的商品，ECtouch商城默认好像没有此调用方式，只能自己动手添加了。

方法如下：

1、打开mobile\include\apps\default\model\IndexModel.class.php

在最下面 ｝ 之前添加以下代码

/*** 获得指定分类下的商品*/function assign_cat_goods($cat_id) {$children = get_children($cat_id);$sql = 'SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ' ."IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, " .'g.promote_price, promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' ."FROM " . $this->pre . 'goods AS g ' ."LEFT JOIN " . $this->pre . "member_price AS mp " ."ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' " .'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND ' .'g.is_delete = 0 AND (' . $children . 'OR ' . model('Goods')->get_extension_goods($children) . ') ';$sql .= 'ORDER BY g.sort_order, g.goods_id DESC';$sql .= ' LIMIT 3';$res = $this->query($sql);$goods = array();foreach ($res AS $idx => $row) {if ($row['promote_price'] > 0) {$promote_price = bargain_price($row['promote_price'], $row['promote_start_date'], $row['promote_end_date']);$goods[$idx]['promote_price'] = $promote_price > 0 ? price_format($promote_price) : '';} else {$goods[$idx]['promote_price'] = '';}$goods[$idx]['id'] = $row['goods_id'];$goods[$idx]['name'] = $row['goods_name'];$goods[$idx]['brief'] = $row['goods_brief'];$goods[$idx]['market_price'] = price_format($row['market_price']);$goods[$idx]['short_name'] = C('goods_name_length') > 0 ?sub_str($row['goods_name'], C('goods_name_length')) : $row['goods_name'];$goods[$idx]['shop_price'] = price_format($row['shop_price']);$goods[$idx]['thumb'] = get_p_w_picpath_path($row['goods_id'], $row['goods_thumb'], true);$goods[$idx]['goods_img'] = get_p_w_picpath_path($row['goods_id'], $row['goods_img']);$goods[$idx]['url'] = build_uri('goods/index', array('id' => $row['goods_id']));}ECTouch::view()->assign('cat_goods_' . $cat_id, $goods);return $goods;}

其中：

$sql .= ' LIMIT 3';

数字 3 代表的是调用3个商品，可自己修改

2、打开：mobile\include\apps\default\controller\IndexController.class.php

在 public function index()函数里面添加以下代码：

//首页指定分类下的商品$this->assign('cat_id1', model('Index')->assign_cat_goods(1));$this->assign('cat_id5', model('Index')->assign_cat_goods(5));

代码中的数字1和5  代表 分类ID1和分类ID5

可自己修改或新增

3、打开模板index.dwt，在合适位置添加调用代码：

{foreach from=$cat_id5 item=goods name=cat_id5}<li> <a href="{$goods.url}" title="{$goods.name|escape:html}"><div class="products_kuang"> <img src="{$option.static_path}{$goods.thumb}"> </div><div class="goods_name"> {$goods.name} </div><span class="price">{if $goods.promote_price}{$goods.promote_price}{else}{$goods.shop_price}{/if}</span> </a></li>{/foreach}

from=$cat_id5

自己修改from值
