多商户商品下单限购问题修复

问题: 当商品设置限购为 1 时,够买数量未超过限购,但是还是提示超出限购数量

修复方法:

修改代码路径:

app\common\repositories\store\order\StoreOrderCreateRepository.php

修改代码一:

$is_pays = array_unique(array_column($merchantCart['list'],'is_pay'));
if ( count($is_pays) > 1 || $is_pays[0] == 1) throw new ValidateException('存在已购买商品请重新添加购物车');
// 获取每个商品的ID数组
$product_ids = array_column($merchantCart['list'],'product_id');
$num_data = array_column($merchantCart['list'],'cart_num');
$id_num = [];
// 获取每个商品ID出现的次数及购买数量，作为验证限购数量使用
foreach ($product_ids as $key => $value) {    
    $id_num[$value] = isset($id_num[$value]) ? $id_num[$value] + $num_data[$key] : $num_data[$key];
}
$countList = count($merchantCart['list']);

修改后的样子:

修改代码二:

$count = $id_num[$cart['product_id']];
if (($count) > $cart['product']['once_max_count']) {    
    throw new ValidateException('[超出限购总数：' . $cart['product']['once_max_count'] . ']' . mb_substr($cart['product']['store_name'], 0, 10) . '...');
}
$pay_count = $storeOrderRepository->getMaxCountNumber($cart['uid'], $cart['product_id']);
if (($count + $pay_count) > $cart['product']['once_max_count']) {    
    throw new ValidateException('[超出限购总数：' . $cart['product']['once_max_count'] . ']' . mb_substr($cart['product']['store_name'], 0, 10) . '...');
}

修改后的样子:

最后:修改完了需要重启swoole服务
