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 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 个插件也是很实用的插件就是如果在后台设置商品很小起订量
步骤一,商品表必须有个字段  代表某个商品 很小订购数量->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  代表没有很小起订量
sql:alter table `goods` add column `min_number` tinyint (3) UNSIGNED  DEFAULT '0' NOT NULL  after `warn_number`
步骤二,在后台添加商品的时候 必须有个text文本框  设置很小起订量
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']) ? $_POST['min_number'] : 0;
步骤三,修改添加商品sql语句
修改代码
if ($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', '$catgory_id', " .
 "'$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',".
 "'$warn_number','$min_number', '$_POST[integral]', '$give_integral', '$is_best', '$is_new', '$is_hot', '$is_on_sale', '$is_alone_sale', ".
 "'$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type','$rank_integral')";
 }else{
  $sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, ".
 "cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " .
  "promote_start_date, promote_end_date, goods_img, goods_thumb, original_img,keywords, goods_brief, " .
  "seller_note, goods_weight, goods_number, warn_number, min_number,integral,give_integral, is_best, is_new, is_hot, is_real, " .
  "is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type,extension_code, rank_integral)" .
  "VALUES ('$_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',".
  " '$warn_number','$min_number', '$_POST[integral]', '$give_integral', '$is_best','$is_new', '$is_hot', 0, '$is_on_sale', '$is_alone_sale’' ".
  " '$_POST[goods_desc]', '" . gmtime() . "', '". 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 = '$_REQUEST[goods_id]' LIMIT 1";
 }
步骤四,修改后台模板文件(在市场价会员价  后边添加设置很小起订量)
admin/templates/goods_info.htm
<tr>
<td class="label">{$lang.lab_shop_price}</td>
<td><input type="text" name="market_price" value="{$goods.shop_price}" size="20" />
<input type="button" value="{$lang.integral_market_price}" onclick="integral_market_price()" />{$lang.require_field}</td>
</tr>
添加
<!-- 新增 批发数量限制 begin --> 
<tr> 
<td class="label">{$lang.lab_min_number}</td> 
<td><input type="text" name="min_number" value="{$goods.min_number}" size="20" />
<span class="notice-span" {if $help_open}style="display:block" {else} style="display:none" mce_style="display: none;" {/if} id="minNumber">{$lang.notice_min_number}</span>
</td>
</td>
</tr>
<!-- 批发数量限制 end -->
步骤五,修改语言languages/zh_cn/admin/goods.php
最后添加
$_LANG['lab_min_number']= '很小购买数量:';
$_LANG['notice_min_number']= '该商品很小购买数量,0表示按购买数量制.'
到现在位置 后台设置全部结束了,不知道大家能懂了没有
下面我门说说前台如何来实现
我以default模板为例子给大家讲解
想做起订量限制,这个必然是在商品购买页面  购买数量框来做限制 最简单的办法就是用JS当然还有别的办法
首先给那些如果给了起订量的商品  购买页面直接显示默认最少购买数量
如果在后台设置的AA商品最少5个那么进入AA商品页面购买数量默认值就是5
我这样来实现
修改themes/default/goods.dwt
<input name="number" type="text" id="number" value="1" size="4" onBlur="changePrice()" style="border:1px solid #ccc; " mce_style="border: 1px solid #ccc;"/>
改成
<input name="number" type="text" id="number" value="{$goods.min_number|default:"1"}" size="4" onblur="changePrice()" style=”border:1px solid #ccc; " mce_style="border: 1px solid #ccc;"/><br />
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
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很小购买数量:{$goods.min_number}');
qty = {$goods.min_number};
}
{/if}
