php - 如何将参数正确传递给贝宝按钮（laravel）

问题描述

我正在创建一个小购物车，将您购买的商品的价值传递到贝宝购物车，以便您快速结帐。我的问题是它目前为每个添加到购物车的商品创建一个贝宝按钮。我来给你展示。

在此处输入图像描述

由于购物车中有 3 件商品，因此有 3 个按钮。一旦您查看源代码，就会发现它非常明显：代码位于 @foreach 列中。我的问题是，如何初始化值 $id => $details 以便我可以传递正在处理的产品的实际值，这样用户就不需要手动输入他或她想要的产品？我还没有找到不使用“@foreach”东西的方法。让我向您展示我的代码：

这是 layout.blade.php：

解决方案

使用购物车上传呈现单个按钮，而不是添加到购物车按钮。然而，这一切都已经很老了。您应该集成当前版本的PayPal Checkout ，而不是这些 HTML 按钮。

由于您有一台服务器，请制作两条路线：一条用于“创建订单”，一条用于“捕获订单”，记录在此处。这些路由应该只返回 JSON 数据（没有 HTML 或文本）。后者应该（成功时）在返回之前将付款详细信息存储在您的数据库中（特别purchase_units[0].payments.captures[0].id是 PayPal 交易 ID）

将这两条路线与以下批准流程配对：https ://developer.paypal.com/demo/checkout/#/pattern/server
