针对下架的商品，加入购物车后仍能购买的问题（原ecshop也存在此问题）修复

 修复效果如上：

另外结算时也会验证是否下架！

修改如下：

1、themes/shop/library/flow_cart.lbi

找到：

<tdclass="ta-c"><inputtype="checkbox"name="goodsId"value="{$goods.rec_id}"></td>

修改为：

<tdclass="ta-c"><inputtype="checkbox"{if!$goods.is_on_sale}disabled="disabled"autocomplete="off"{else}checked="checked"{/if}name="goodsId"value="{$goods.rec_id}"></td>

2、includes/lib_order.php

找到：

functioncart_goods($type=CART_GENERAL_GOODS)

{

$sql="SELECTc.rec_id,c.user_id,c.goods_id,c.goods_name,g.goods_thumb,g.goods_name,c.goods_sn,c.goods_number,".

修改为：

functioncart_goods($type=CART_GENERAL_GOODS)

{

$sql="SELECTc.rec_id,c.user_id,c.goods_id,g.is_on_sale,c.goods_name,g.goods_thumb,g.goods_name,c.goods_sn,c.goods_number,".

找到：

$goods_thumb=$GLOBALS['db']->getOne("SELECT`goods_thumb`FROM".$GLOBALS['ecs']->table('goods')."WHERE`goods_id`='{$row['goods_id']}'");

$row['goods_thumb']=get_image_path($row['goods_id'],$goods_thumb,true);

修改为：

$goods_info=$GLOBALS['db']->getRow("SELECT`goods_thumb`,`is_on_sale`FROM".$GLOBALS['ecs']->table('goods')."WHERE`goods_id`='{$row['goods_id']}'");

$goods_thumb=$goods_info['goods_thumb'];

$row['is_on_sale']=$goods_info['is_on_sale'];

$row['goods_thumb']=get_image_path($row['goods_id'],$goods_thumb,true);

3、最后找到：flow.php

/*统计实体商品的个数*/

if($val['is_real'])

{

$is_real_good=1;

}

在其上添加：

if(!$val['is_on_sale'])

{

show_message('商品：'.$val['goods_name'].'已下架！','返回购物车','flow.php','warning');

}
