ecshop每个商品添加最少购买量最小订购量

第一步，商品表必须有个字段代表某个商品 最小订购数量->min_number
打开goods表在最后字段添加一个min_numbertinyint类型 默认值为0代表没有最小起订量
sql:alter table `goods` add column `min_number` tinyint (3) UNSIGNEDDEFAULT '0' NOT NULLafter `warn_number`
第二部,在后台添加商品的时候 必须有个text文本框设置最小起订量
admin/goods.php
在'warn_number'=> 1 , 代码行后插入'min_number'=> 0,
在$warn_number = isset($_POST['warn_number']) ? $_POST['warn_number'] : 0;
后添加代码$min_number = isset($_POST['min_number']) ? $_POST['min_number'] : 0;
第三部 修改添加商品sql语句
修改代码

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