872天前第一步，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, " . |

} |
}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 " . |

|
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', "; |

"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 <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 --> |
第五步:修改语言languages/zh_cn/admin/goods.php |
最后添加 |
$_LANG['lab_min_number'] = '最小购买数量:'; |
$_LANG['notice_min_number'] = '该商品最小购买数量,0表示按购买数量无限制.' |
到现在位置 后台设置全部结束了，不知道大家能懂了没有 |
下面我门说说前台如何来实现 |
我以default模板为例子给大家讲解 |
想做起订量限制，这个必然是在商品购买页面 购买数量框来做限制最简单的办法就是用JS当然还有别的办法 |
首先给那些如果给了起订量的商品 购买页面直接显示默认最少购买数量 |
如果在后台设置的AA商品最少5个 那么进入AA商品页面购买数量默认值就是5 |
我这样来实现 |
修改themes/default/goods.dwt |
<input name="number" type="text" id="number" value="1" size="4" onBlur="changePrice()" style="border:1px solid #ccc; " mce_style="border: 1px solid #ccc;"/> |
改成 |
<input name="number" type="text" id="number" value="{$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 |
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} |
