如何实现商品批发增加起订数功能，现在和大家分享一下啊1.在ECS_goods数据表中新增最小购买数量字段min_number
alter table `ecs_goods` add column `min_number` tinyint (3) UNSIGNED DEFAULT '0' NOT NULL after
`warn_number`
2.修改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;
代码行后插入
$min_number = isset($_POST['min_number']) ? $_POST['min_number'] : 0;
/* 入库 */
if ($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

}
}
else
{
/* 如果有上传图片，删除原来的商品图 */
$sql = "SELECT goods_thumb, goods_img, original_img " .
" FROM " . $ecs->table('goods') .

$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

{
@unlink(ROOT_PATH . $row['goods_thumb']);
}

/* 如果有上传图片，需要更新数据库 */
if ($goods_img)
{
$sql .= "goods_img = '$goods_img', original_img = '$original_img', ";
}

"last_update = '". gmtime() ."', ".
"goods_type = '$goods_type' " .
"WHERE goods_id = '$_REQUEST[goods_id]' LIMIT 1";
}
3.修改admin/templates/goods_info.htm
在
<!--商品优惠价格 end -->
<tr>
<td class="label">{$lang.lab_market_price}</td>
<td><input type="text" name="market_price" value="{$goods.market_price}" size="20" />
<input type="button" value="{$lang.integral_market_price}"
onclick="integral_market_price()" />
</td>
</tr>
之后新增插入
<!--新增 批发数量限制 begin -->
<tr>
<td class="label">{$lang.lab_min_number}</td>
<td><input type="text" name="min_number" value="{$goods.min_number}" size="20" />
<br /><span class="notice-span" {if $help_open}style="display:block" {else}
style="display:none" {/if} id="minNumber">{$lang.notice_min_number}</span></td>
</td>
</tr>
<!-- 批发数量限制 end -->
在
<!--商品优惠价格 end -->
<tr>
<td class="label">{$lang.lab_market_price}</td>
<td><input type="text" name="market_price" value="{$goods.market_price}" size="20" />
<input type="button" value="{$lang.integral_market_price}"
onclick="integral_market_price()" />
</td>
</tr>
之后新增插入
<!--新增 批发数量限制 begin -->
<tr>
<td class="label">{$lang.lab_min_number}</td>
<td><input type="text" name="min_number" value="{$goods.min_number}" size="20" />
<br /><span class="notice-span" {if $help_open}style="display:block" {else}
style="display:none" {/if} id="minNumber">{$lang.notice_min_number}</span></td>
</td>
</tr>
<!-- 批发数量限制 end -->
4.修改languages/zh_cn/admin/goods.php
在文件最后新增
/* 新增 */
$_LANG['lab_min_number'] = '最小购买数量:';
$_LANG['notice_min_number'] = '该商品最小购买数量,0表示按购买数量无限制.';
5.修改themes/default/goods.dwt
将
<input name="number" type="text" id="number" value="1" size="4"
style="border:1px solid #ccc; "/>
修改成
<input name="number" type="text" id="number" value="{$goods.min_number|default:"1"}" size="4"
onblur="changePrice()" style="border:1px solid #ccc; "/>
在
var qty = document.forms['ECS_FORMBUY'].elements['number'].value;
之后添加
<!-- {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} -->
