Magento 2 创建购物车价格规则并且自动生成优惠券代码

作者 1,441

Magento提供购物车价格规则营销功能，允许根据一组条件对购物车中的商品应用折扣。只要满足条件，或者客户输入有效的优惠券代码，就可以自动应用折扣。优惠券代码可以通过管理面板的Marketing -> Cart Price Rules部分按购物车价格规则生成。但是，有时我们需要自动执行此过程。让我们来看看如何在Magento 2中以编程方式创建购物车价格规则并生成优惠券代码。

首先，我们创建一个服务类，旨在使用默认优惠券生成器（\Magento\SalesRule\Model\CouponGenerator）生成优惠券代码。如果我们想要通过预定的CRON计划任务生成优惠券代码，将来可以重复使用该服务。或者我们甚至可以另外创建一个新的CLI命令，它允许通过简单地调用\Atwix\CartCouponSample\Service\GenerateCouponCodesService::execute方法为指定的购物车价格规则生成许多代码。

<?php
/* File: app/code/Atwix/CartCouponSample/Service/GenerateCouponCodesService.php */
namespace Atwix\CartCouponSample\Service;
 
use Magento\SalesRule\Model\CouponGenerator;
 
/**
* Class GenerateCouponListService
*/
class GenerateCouponCodesService
{
    /**
     * Coupon Generator
     *
     * @var CouponGenerator
     */
    protected $couponGenerator;
 
    /**
     * GenerateCouponCodesService constructor
     *
     * @param CouponGenerator $couponGenerator
     */
    public function __construct(CouponGenerator $couponGenerator)
    {
        $this->couponGenerator = $couponGenerator;
    }
 
    /**
     * Generate coupon list for specified cart price rule
     *
     * @param int|null $qty
     * @param int|null $ruleId
     * @param array $params
     *
     * @return void
     */
    public function execute(int $qty, int $ruleId, array $params = []): void
    {
        if (!$qty || !$ruleId) {
            return;
        }
 
        $params['rule_id'] = $ruleId;
        $params['qty'] = $qty;
 
        $this->couponGenerator->generateCodes($params);
    }
}

 

然后，我们实现一个设置服务类，用于创建购物车价格规则并将优惠券代码分配给新创建的规则。我们将此逻辑移至专用的安装服务类，只是为了遵循单一责任原则并避免存储在安装脚本中的大量逻辑。

以下步骤通过以下\Atwix\CartCouponSample\Setup\SetupService\CreateCartPriceRuleService::execute方法执行：

  1. 使用工厂创建购物车价格规则对象。
  2. 将所需数据和其他配置设置为购物车价格规则对象。我们还使用优惠券类型“特定优惠券”并设置“使用自动生成”标志以使多个优惠券代码生成成为可能。
  3. 使用相应的存储库保存购物车价格规则。注意，在这种情况下，由于现有的实现，我们需要设置区号RuleRepository。RuleRepository::save从CLI 运行方法时需要模拟特定区域，以避免相应的错误（“区域代码未设置”）。
  4. 使用，生成优惠券代码并将其分配给新创建的购物车价格规则Atwix\CartCouponSample\Service\GenerateCouponCodesService。

现在，让我们为我们的模块创建数据安装脚本：
