    <form action="flow.php" method="post" name="ECS_ALL_addcart" >
                 <table width="100%" border="0" cellpadding="0" cellspacing="2" bgcolor="#FFFFFF">
  <tr bgcolor="#5e554e" style="color:#FFFFFF;">
    <td align="center" width="150">货号</td>
    <td align="center" width="150">规格</td>
    <td align="center" width="80">销售价</td>
    <td align="center" width="140">会员价</td>
    <td align="center">订购数量</td>
    <td align="center">库存</td>
  </tr>
 <!-- {foreach from=$product_list item=product} -->
  <tr bgcolor="#f7f7f7">
    <td align="center" >{$product.product_sn}<input name="product_sn[{$product.product_id}]" id="number" value="{$product.product_sn}" type="hidden"  /></td>
    <td align="center" >
 <!--{foreach from=$product.goods_attr_id item=goods_attr_id  }-->
  <input name="goods_attr[{$product.product_id}][]"  type="hidden"  value="{$goods_attr_id}"  />
  <!-- {/foreach}-->
 <!--{foreach from=$product.goods_attr item=goods_attr name=pro }--> {$goods_attr}

 <!--{if $smarty.foreach.pro.iteration ne $smarty.foreach.pro.total}--> | <!--{/if}-->
          <!-- {/foreach}--></td>
    <td align="center" >{$goods.shop_price_formated}</td>
    <td align="center" >   <!-- 会员等级对应的价格{foreach from=$rank_prices item=rank_price key=key} -->
               {$rank_price.rank_name}： <span class="goodsPrice" id="ECS_RANKPRICE_{$key}">{$rank_price.price}</span>
                <!-- {/foreach} --></td>
    <td align="center" ><input name="number[{$product.product_id}]" id="number" value="1" type="text" size="3" /></td>
    <td align="center" >{$product.product_number}</td>
  </tr>
   <!-- {/foreach}-->
  <tr>
    <td colspan="6" align="right"><input type="image" name="submit" src="images/add_cart.gif"></td>
    </tr>
</table>
<input name="goods_id"  value="{$goods.goods_id}" type="hidden"  />
<input name="step"  value="all_addcart" type="hidden" />
</form>

2、打开goods.php 加入

$smarty->assign('product_list',product_list($goods_id, ''));

3、打开flow.php加入

//-- 添加商品到购物车(西安php服务中心修改)

/*------------------------------------------------------ */
if($_REQUEST['step'] =='all_addcart')
{
    $goods_id = $_POST["goods_id"];
 //获得批发相关值
 foreach($_POST['number'] as $idx=>$value)
 {
  $number = $value;
  $number_all= $value+$number_all;
  $goods_attr_id = join(",",$_POST['goods_attr'][$idx]);
  $product_sn = $_POST['product_sn'][$idx];
     addto_cart($goods_id,$number,$_POST['goods_attr'][$idx],'',$content);
  $arr[$idx] = array('number'=>$number,'goods_attr'=>$goods_attr_id,'product_sn'=>$product_sn);
 // $sql = $GLOBALS['db']->query("insert into ".$GLOBALS['ecs']->table('cart_p')." (goods_id,product_id,number,goods_attr,product_sn,session_id) values('$goods_id','$idx','$number','$goods_attr_id','$product_sn','".SESS_ID."')");
 }
 //商品id
// $content = serialize($arr);
 //$number = $number_all;
 
    ecs_header("Location:./flow.php\n");

}
