我一直在研究 PayPal 的替代方案,用于在线支付和从 github (https://github.com/square/connect-api-examples/tree/master/connect-examples/v2/php_payment) 下载的 Square Ups 演示文件。在使用 Square 创建帐户并安装 Composer 后,演示工作正常,但我注意到付款金额是在 'process-card.php' 上的演示中硬编码的。那么如何从表单输入或数据库值传递金额?

好的，这里是表单页面：

首先，您需要在主付款表单上有一个隐藏或文本字段...
<input type="text" name="manual-amount">
然后在 process_card 页面上，您需要从 POST 数据中获取传入的表单字段。（以下显示在 Python 中，对不起...），但几乎完全是如何提取 NONCE 数据的。
nonce = form.getvalue('nonce')
amount = form.getvalue('manual-amount')
在该部分中，将硬编码的 100 替换为您刚刚从上面的 POST 数据中获得的金额值的整数值...
# Monetary amounts are specified in the smallest unit of the applicable currency.
# This amount is in cents. It's also hard-coded for $1.00, which isn't very useful.
amount = {'amount': int(amount), 'currency': 'GBP'}
希望这会给你和其他人一些关于如何在 PHP 和其他语言中做到这一点的想法。
