做过ecshop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 今天第一个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 `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']) ? $_POST['min_number'] : 0; 第三部 修改添加商品sql语句 修改代码 if ($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() ."', '$goods_type','$rank_integral')"; }else{ $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, " .

" 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') .

"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}
