购物车中商品较多直接全选下单，商品没有全部下单问题

1、路径：app\controller\api\v1\store\StoreCartController.php 方法: count()；更改如下：public function count(Request $request)

{

[$numType] = $request->postMore([

['numType', true],//购物车编号

], true);

$uid = (int)$request->uid();

return app('json')->success('ok', $this->services->getUserCartCount($uid, $numType));

}

2、路径：app\services\order\StoreCartServices.php 增加如下方法：

/**

* 获取用户购物车数量 ids 统计金额

* @param int $uid

* @param string $numType

* @throws \think\db\exception\DataNotFoundException

* @throws \think\db\exception\DbException

* @throws \think\db\exception\ModelNotFoundException

*/

public function getUserCartCount(int $uid, string $numType)

{

$count = 0;

$ids = [];

$sum_price = 0;

$cartList = $this->dao->getUserCartList($uid, 'product', '*', ['productInfo', 'attrInfo']);

if ($cartList) {

/** @var StoreProductServices $productServices */

$productServices = app()->make(StoreProductServices::class);

/** @var MemberCardServices $memberCardService */

$memberCardService = app()->make(MemberCardServices::class);

$vipStatus = $memberCardService->isOpenMemberCard('vip_price');

/** @var UserServices $user */

$user = app()->make(UserServices::class);

$userInfo = $user->getUserInfo($uid);

/** @var SystemUserLevelServices $systemLevel */

$systemLevel = app()->make(SystemUserLevelServices::class);

$discount = $systemLevel->value(['id' => $userInfo['level'], 'is_del' => 0, 'is_show' => 1], 'discount') ?: null;

foreach ($cartList as &$item) {

$productInfo = $item['productInfo'];

if (isset($productInfo['attrInfo']['product_id']) && $item['product_attr_unique']) {

$item['truePrice'] = $productServices->setLevelPrice($productInfo['attrInfo']['price'] ?? 0, $uid, $userInfo, $vipStatus, true, $discount, $item['attrInfo']['vip_price'] ?? 0, $productInfo['is_vip'] ?? 0, true);

} else {

$item['truePrice'] = $productServices->setLevelPrice($item['productInfo']['price'] ?? 0, $uid, $userInfo, $vipStatus, true, $discount, $item['attrInfo']['vip_price'] ?? 0, $item['productInfo']['is_vip'] ?? 0);

}

$sum_price = bcadd((string)$sum_price, (string)bcmul((string)$item['cart_num'], (string)$item['truePrice'], 4), 2);

}

$ids = array_column($cartList, 'id');

if ($numType) {

$count = count($cartList);

} else {

$count = array_sum(array_column($cartList, 'cart_num'));

}

}

return compact('count', 'ids', 'sum_price');

}

3：路径：app\dao\order\StoreCartDao.php 增加如下方法：

/**

* 用户购物车统计数据

* @param $uid

* @param $type

* @param string $field

* @param array $with

* @return array

* @throws \think\db\exception\DataNotFoundException

* @throws \think\db\exception\DbException

* @throws \think\db\exception\ModelNotFoundException

*/

public function getUserCartList($uid, $type, string $field = '*', array $with = [])

{

return $this->getModel()->where(['uid' => $uid, 'type' => $type, 'is_pay' => 0, 'is_new' => 0, 'is_del' => 0])->when(count($with), function ($query) use ($with) {

$query->with($with);

})->order('add_time DESC')->field($field)->select()->toArray();

}

4：前端uni-app代码；

（1） 包中位置：view/uni-app 直接下载附件解压覆盖

（2）或者解压附件找到order_addcart.vue与路径 pages/order_addcart/order_addcart.vue 比较合并

5:前端需要重新打包H5放入public/下
