做过商城，或者说经营过商城的都会知道，有很多商品利润很小，而且还要包运费什么的，所以根本就是做亏本的生意，如果利润小，数量多的话 这样就不会出现赔本的损失。所以 ECSHOP商品限制购买批发起订数量插件也是很实用的插件,就是如果在后台设置商品最小起订量 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_number tinyint类型默认值为0 代表没有最小起订量 sql:alter table `ecs_goods` add column `min_number` tinyint (3) UNSIGNED DEFAULT '0' NOT NULL after `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']) ? $_POST['min_number'] : 0; 第三部修改添加商品sql语句 将 /* 入库 */ if ($is_insert) { if ($code == '') { ....由于发帖篇幅的限制省略原有代码无数 } else { ...... } } else { /* 如果有上传图片，删除原来的商品图 */ ..... } 修改代码 if ($is_insert){ if ($code == ''){ $sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, " . "cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " . "promote_start_date, promote_end_date, goods_img, goods_thumb, original_img,keywords, goods_brief, " . "seller_note, goods_weight, goods_number, warn_number,min_number, integral,give_integral, is_best, is_new, is_hot, ". "is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type,rank_integral)" . "VALUES ('$_POST[goods_name]', '$goods_name_style', '$goods_sn', '$catgory_id', " .

"', '". gmtime() ."', '$goods_type', '$code', '$rank_integral')"; } }else{ $sql = "SELECT goods_thumb, goods_img, original_img " . " FROM " . $ecs->table('goods') . " WHERE goods_id = '$_REQUEST[goods_id]'"; $row = $db->getRow($sql); if ($proc_thumb && $goods_img && $row['goods_img'] && !goods_parse_url($row['goods_img'])) { @unlink(ROOT_PATH . $row['goods_img']); @unlink(ROOT_PATH . $row['original_img']); } if ($proc_thumb && $goods_thumb && $row['goods_thumb'] && !goods_parse_url($row['goods_thumb'])) { @unlink(ROOT_PATH . $row['goods_thumb']); } $sql = "UPDATE " . $ecs->table('goods') . " SET " . "goods_name = '$_POST[goods_name]', " . "goods_name_style = '$goods_name_style', " . "goods_sn = '$goods_sn', " . "cat_id = '$catgory_id', " . "brand_id = '$brand_id', " . "shop_price = '$shop_price', " . "market_price = '$market_price', " . "is_promote = '$is_promote', " . "promote_price = '$promote_price', " . "promote_start_date = '$promote_start_date', " . "promote_end_date = '$promote_end_date', "; if ($goods_img) { $sql .= "goods_img = '$goods_img', original_img = '$original_img', "; } if ($goods_thumb) { $sql .= "goods_thumb = '$goods_thumb', "; } if ($code != '') { $sql .= "is_real=0, extension_code='$code', "; } $sql .= "keywords = '$_POST[keywords]', " . "goods_brief = '$_POST[goods_brief]', " . "seller_note = '$_POST[seller_note]', " . "goods_weight = '$goods_weight'," . "goods_number = '$goods_number', " . "warn_number = '$warn_number', " . "min_number = '$min_number', " . "integral = '$_POST[integral]', " . "give_integral = '$give_integral', " . "rank_integral = '$rank_integral', " . "is_best = '$is_best', " . "is_new = '$is_new', " . "is_hot = '$is_hot', " . "is_on_sale = '$is_on_sale', " . "is_alone_sale = '$is_alone_sale', " . "goods_desc = '$_POST[goods_desc]', " . "last_update = '". gmtime() ."', ". "goods_type = '$goods_type' " . "WHERE goods_id = '$_REQUEST[goods_id]' LIMIT 1"; } 第四步修改后台模板文件(在市场价会员价 后边添加设置最小起订量) admin/templates/goods_info.htm 在
这样就是value 也就是默认值了 最后添加JS判断就好了 themes/default/goods.dwt 在 var qty = document.forms['ECS_FORMBUY'].elements['number'].value; 后添加 {if $goods.min_number} if(qty < {$goods.min_number}) { alert('您输入的数字小于此商品最小购买数量：{$goods.min_number}'); qty = {$goods.min_number}; } {/if}
