ecshop二次开发——商品列表页显示重量、货号、购买数量

升级说明

在列表页中显示克重、货号信息，用户可以在列表页直接输入要购买的数量。

升级方法

【1】themes\default\library\goods_list.lbi文件中找到<div class=”goodsItem”>，将改标签的内容修改如下：

<div class="goodsItem">
           <ahref="{$goods.url}"><img src="{$goods.goods_thumb}"alt="{$goods.goods_name}" class="goodsimg"/></a><br />
           <p><ahref="{$goods.url}"title="{$goods.name|escape:html}">{$goods.goods_name}</a></p>
           <!-- {if$show_marketprice} -->
           {$lang.market_prices}<fontclass="market_s">{$goods.market_price}</font><br />
            <!-- {/if}-->
            <!--{if$goods.promote_price neq "" } -->
           {$lang.promote_price}<fontclass="shop_s">{$goods.promote_price}</font><br />
           <!--{else}-->
           {$lang.shop_prices}<fontclass="shop_s">{$goods.shop_price}</font><br />
            <!--{/if}-->
           {$lang.goods_sn}{$goods.goods_sn}<br />
           {$lang.goods_weight}{$goods.goods_weight}{$lang.gram}<br />
            {$lang.number}£º
            <inputname="number" type="text" id="{$goods.goods_id}"value="1" size="1" onblur="changePrice()"style="border:1px solid #ccc; "/>
           <ahref="javascript:collect({$goods.goods_id});"class="f6">{$lang.btn_collect}</a> |
           <ahref="javascript:addToCartFromCategory({$goods.goods_id})"class="f6">{$lang.btn_buy}</a> |
           <ahref="javascript:;" id="compareLink"onClick="Compare.add({$goods.goods_id},'{$goods.goods_name|escape:"html"}','{$goods.type}')"class="f6">{$lang.compare}</a>
        </div>
 

【2】js\common.js中增加一个函数：

/* *
 * 将列表页的商品直接添加商品到购物车
 */
function addToCartFromCategory(goodsId, parentId)
{
    var goods        = new Object();
    var spec_arr     = new Array();
    var fittings_arr = newArray();
    var number       = 1;
    var quick            = 0;
      
    number =document.getElementById(goodsId).value;
   
    quick = 1;
      
    goods.quick    = quick;
    goods.spec     = spec_arr;
    goods.goods_id = goodsId;
    goods.number   = number;
    goods.parent   = (typeof(parentId) =="undefined") ? 0 : parseInt(parentId);
 
   Ajax.call('flow.php?step=add_to_cart', 'goods=' + goods.toJSONString(),addToCartResponse, 'POST', 'JSON');
} 

【3】category.php文件中：

将获得商品列表的sql查询由：

/* 获得商品列表 */
    $sql = 'SELECT g.goods_id,g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best,g.is_hot, g.shop_price AS org_price, ' .
               "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') ASshop_price, g.promote_price, g.goods_type, " .
               'g.promote_start_date, g.promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
            'FROM ' .$GLOBALS['ecs']->table('goods') . ' AS g ' .
            'LEFT JOIN ' .$GLOBALS['ecs']->table('member_price') . ' AS mp ' .
                "ONmp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' " .
            "WHERE $where$ext ORDER BY $sort $order";

改为：

$sql = 'SELECT g.goods_id, g.goods_name, g.goods_sn, g.goods_weight,g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_priceAS org_price, ' .
                "IFNULL(mp.user_price,g.shop_price * '$_SESSION[discount]') AS shop_price, g.promote_price,g.goods_type, " .
               'g.promote_start_date, g.promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
            'FROM ' .$GLOBALS['ecs']->table('goods') . ' AS g ' .
            'LEFT JOIN ' .$GLOBALS['ecs']->table('member_price') . ' AS mp ' .
                "ONmp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' " .
            "WHERE $where$ext ORDER BY $sort $order";

同时，在本文件的：

$arr[$row['goods_id']]['name']             = $row['goods_name'];
       $arr[$row['goods_id']]['goods_brief']      = $row['goods_brief'];
       $arr[$row['goods_id']]['goods_style_name'] =add_style($row['goods_name'],$row['goods_name_style']);
       $arr[$row['goods_id']]['market_price']     = price_format($row['market_price']);
       $arr[$row['goods_id']]['shop_price']       = price_format($row['shop_price']);
       $arr[$row['goods_id']]['type']             = $row['goods_type'];
        $arr[$row['goods_id']]['promote_price']    = ($promote_price > 0) ?price_format($promote_price) : '';
       $arr[$row['goods_id']]['goods_thumb']      = get_image_path($row['goods_id'],$row['goods_thumb'], true);
       $arr[$row['goods_id']]['goods_img']        = get_image_path($row['goods_id'],$row['goods_img']);
       $arr[$row['goods_id']]['url']              = build_uri('goods',array('gid'=>$row['goods_id']), $row['goods_name']);

之后追加以下两行内容：

     

  $arr[$row['goods_id']]['goods_sn']         = $row['goods_sn'];
       $arr[$row['goods_id']]['goods_weight']     = $row['goods_weight'];
