取出购买记录、评价记录、订单页面取出商品图片

调用购买评价：

$goods[$id]['num']         = get_buy_sum($row['goods_id']);//购买
$goods[$id]['pingjia']         = get_comment_num($row['goods_id'],1,5);//评价

$goods_list[$key]['goods_thumb'] = $val["goods_thumb"];//取出商品图片

php页面方法：

//ecshop实现销售多少件的功能

function get_buy_sum($goods_id)
{
$sql = 'SELECT IFNULL(SUM(g.goods_number), 0) ' .
'FROM ' . $GLOBALS['ecs']->table('order_info') . ' AS o, ' .
$GLOBALS['ecs']->table('order_goods') . ' AS g ' .
"WHERE o.order_id = g.order_id " . 
//"AND o.order_status = '" . OS_CONFIRMED . "' " .                 //订单状态
//"AND o.shipping_status " . db_create_in(array(SS_SHIPPED, SS_RECEIVED)) .  //配送状态
//" AND o.pay_status " . db_create_in(array(PS_PAYED, PS_PAYING)) .          //支付状态
" AND g.goods_id = '$goods_id'";
return $GLOBALS['db']->getOne($sql);
}
//取出评论总数
function get_comment_num($goods_id,$num1,$num2)
{
$sql= "select count(*) from ".$GLOBALS['ecs']->table('comment')." where id_value='".$goods_id."' AND status = 1 AND comment_rank>=".$num1." AND comment_rank<=".$num2."";
return $GLOBALS['db']->getOne($sql);

}

//根绝订单参数 取出商品图片

 $goods_list = order_goods($order_id);
    foreach ($goods_list AS $key => $value)
    {
        $goods_list[$key]['market_price'] = price_format($value['market_price'], false);
        $goods_list[$key]['goods_price']  = price_format($value['goods_price'], false);
       //通过订单循环取出ID，通过循环ID获取商品图片 

       $goods_list[$key]['subtotal']     = price_format($value['subtotal'], false);
$arr    = get_img($value['goods_id']);
foreach($arr as $k=>$val)
{
$goods_list[$key]['goods_thumb'] = $val["goods_thumb"];
}
 }

function get_img($gid)
{
$sql="select goods_thumb from " . $GLOBALS['ecs']->table('goods') . " where goods_id=".$gid;
$res=$GLOBALS['db']->getAll($sql);
return $res;
}

PHP页面调取：

1.如果是在单品页面调用：$smarty->assign('buy_num',get_buy_sum($goods_id));

2.如果是取出多个商品，因为要传ID给方法，所以要跟随数据库循环取出：

 while($row = $GLOBALS['db']->fetchRow($result)){
  $catelist[$row['goods_id']]['num'] = get_buy_sum($row['goods_id']);//循环取出购买记录

}

DWT页面展示：

1.单品调用：已 售 出：{$buy_num}件

2.循环调用：已 售 出：{$goods.num}件
