结合ecshop后台“商品编辑”、“商品录入”来谈谈如何给ecshop商品增加一个新字段，假设我们将这个新字段命名为 new_add

1、首先要修改数据表结构，给表 ecs_goods 增加新字段：new_add，

进入ECSHOP后台 》数据库管理 》SQL查询，输入下面SQL语句，提交。注意如果你的数据表前缀不是ecs_ 请自行修改之

alter table ecs_goods add column new_add varchar(64);

2、在ecshop后台的admin\templates\goods_info.htm中增加以下代码。

<tr>

<td class="label">自定义字段</td>

<td><input type="text" name="new_add" value="{$goods.new_add}" size="20"/>

</td>

</tr>

3、在admin/goods.php的elseif ($_REQUEST['act'] == 'insert' || $_REQUEST['act'] == 'update')里面增加以下程序

//新数据

$sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, " .

"cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " .

"promote_start_date, promote_end_date, goods_img, goods_thumb, original_img, keywords, goods_brief, " .

"seller_note, goods_weight, goods_number, warn_number, integral, give_integral, is_best, is_new, is_hot, " .

"is_on_sale, is_alone_sale, is_shipping, goods_desc, add_time, last_update, goods_type, rank_integral, suppliers_id,new_add)" .

"VALUES ('$_POST[goods_name]', '$goods_name_style', '$goods_sn', '$catgory_id', " .

"'$brand_id', '$shop_price', '$market_price', '$is_promote','$promote_price', ".

"'$promote_start_date', '$promote_end_date', '$goods_img', '$goods_thumb', '$original_img', ".

"'$_POST[keywords]', '$_POST[goods_brief]', '$_POST[seller_note]', '$goods_weight', '$goods_number',".

" '$warn_number', '$_POST[integral]', '$give_integral', '$is_best', '$is_new', '$is_hot', '$is_on_sale', '$is_alone_sale', $is_shipping, ".

" '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$rank_integral', '$suppliers_id','$_POST[new_add]')";

//下面这个为更新，在：

$sql = "UPDATE " . $ecs->table('goods') . " SET " .

"goods_name = '$_POST[goods_name]', " .

"goods_name_style = '$goods_name_style', " .

下面加

" new_add = '$_POST[new_add]', " .

这样我们就完成了在ECSHOP后台录入和修改新字段的功能了。

下面再来说一下前台调用的方法：

调用也很简单，直接在模板文件或者 lbi文件里 这么调用即可 {$goods.new_add}
