用PHP做了一个领取优惠券活动的示例代码

业务需求

优惠券活动,具体还是要根据自己的需求。以下是最近实现的优惠券活动,主要的业务需求:根据后端设置优惠券模板,用户类型设置,优惠券活动的开始与结束时间,最后生成不同的优惠券活动链接。

代码环境:

源码主要laravel5.8,一整个活动要贴的代码很多,下面主要贴核心代码,仅供参考。主要还是要根据自己的业务需求来实现功能吧。

以下是后端截图,做成模块化

前端需要做的设置与限制:

1 判断优惠券是否存在或者停用

2 判断活动开始时间与优惠券开始时间

接着领取活动优惠券,需要判断以下情况:

1 活动已结束

2 活动为开始时

3 活动为新用户领取,而领取的用户是老用户

4 活动为老用户领取,而领取的用户是新用户

5 优惠券是否领取完

6 已领取过优惠券提示

7 领取成功

下面核心代码实现

/**

* Function:优惠券领取处理

* Author:cyw0413

* @param $params

* @return array

* @throws \Exception

*/

public function doCoupon($params)

{

$activity_id = $params['activity_id'];

if(!$params){

throw new \Exception("参数错误!");

}

$preg_phone = '/^1[34578]\d{9}$/ims';

$is_mobile = preg_match ($preg_phone, $params['mobile']);

if ($is_mobile == 0) {

throw new \Exception("手机号码不正确!");

}

//隐藏手机号码中间4位

$str_mobile = substr_replace($params['mobile'],'****',3,4);

$activity = $this->find($activity_id);

if(empty($activity)){

throw new \Exception("不存在此活动");

}

$activity_link = $activity->activityLink->where('coupon_status',0); //只选择不停用的优惠券

if(count($activity_link) <= 0){

throw new \Exception("优惠券不存在或者已经停用");

}else{

//查找注册用户ID

$showUser = $this->showUser($params['mobile']);

//主要是过滤掉领取优惠券为0的,用laravel的同学注意看看

$detail = $activity_link->each(function($item,$index) use ($showUser) {

$diffCouponQuantity = $this->diffCouponQuantity($item['config_id'],$item['quantity'],$item['activity_id'],$showUser);

$item->title = $this->getCouponName($item['config_id'])['name'];

throw new \Exception($detail[0]['msg']);

}

}

}

$collection_coupon = collect($detail);

$collection_coupon = $collection_coupon->where('diff', '<=' ,'0'); //去除优惠券剩余数量为0,或者领取优惠券数量-剩余数量 > 0

}

//判断活动开始时间与优惠券开始时间

$act_coupon = ActivityCouponBaseModel::where('activity_id',$activity['activity_id'])->first();

$check_time = $this-> checkCouponTime($act_coupon['start_time'],$activity_link);

if($check_time == 'error'){

throw new \Exception("优惠券领取时间未开始,暂不可领取");

}

//领取活动有以下几种情况

return $result;

}

$checkUser = $this->haveUser($params['mobile']); //检查是新用户,还是老用户 根据自己的业务需求做,这个方法就不贴了

//2: 活动为新用户领取,而领取的用户是老用户

if($activity['user_type'] == 1 && !empty($checkUser)){

$result = [

}

//3:活动为老用户领取,而领取的用户是新用户

//4:优惠券是否领取完

//5:已领取过优惠券提示

用户领取优惠券并发放优惠券

/**

'status' => 200

];

break;

case 2:

//老用户领取

$res = $this->insertUserCoupon($user,$coupon);

return [

'result' => $res,

'status' => 200

];

break;

default:

//新老用户领取,判断是新用户还是老用户,这里的$user是有无配送单,有则为老用户;

if(empty($user)){

$res = $this->addUser($mobile,$coupon);

}else{

$res = $this->insertUserCoupon($user,$coupon); //老用户,直接发放优惠券

}

return [

'result' => $res,

'status' => 200

];

break;

}

}else{

throw new \Exception("优惠券不存在或者已经停用");

领取成功,则发放优惠券

//发放优惠券,有多少张就添加多少张,这里扣除优惠券时,主要用不同的coupon_sn来区别

$onlyCoupon = $this->getCouponName($item['config_id']);

//扣除相应的优惠券数量,这里用到了锁表,防止并发时,优惠券为-1

$couponConfig = CouponConfigBaseModel::where('config_id',$item['config_id'])->lockForUpdate()->first();

if($couponConfig->left_quantity > 0 ){

if($couponConfig->left_quantity >= $item['quantity']){
