php - 如何使用 PayPal rest-api-sdk 设置具有不同计费周期和金额的 PayPal 定期付款？

问题描述

我尝试了以下代码来设置不同的计费周期，但它不起作用。这段代码有什么错误？

提前致谢！

$paymentDefinition_0 = new PaymentDefinition();
$paymentDefinition_1 = new PaymentDefinition();

$paymentDefinition_0->setName('1stPayment')
    ->setType('REGULAR')
    ->setFrequency('DAY')
    ->setFrequencyInterval('1')
    ->setCycles('1000')
    ->setAmount(new Currency(array(
        'value' => $request->20,
        'currency' => 'USD'
    )));
$paymentDefinition_1->setName('2nd Payment')
    ->setType('REGULAR')
    ->setFrequency('DAY')
    ->setFrequencyInterval('1')
    ->setCycles('1000')
    ->setAmount(new Currency(array(
        'value' => $request->30,
        'currency' => 'USD'
    )));
$plan->setPaymentDefinitions(array(
    $paymentDefinition,
    $paymentDefinition_1
));

解决方案

20 和 30 在技术上是常量，您不能将它们作为表单请求中的名称或将它们作为对象的属性访问，这是语法错误

如果它们是恒定的，则硬编码这些值

$paymentDefinition_0->setName('1stPayment')
    ->setType('REGULAR')
    ->setFrequency('DAY')
    ->setFrequencyInterval('1')
    ->setCycles('1000')
    ->setAmount(new Currency(array(
        'value' => 20,
        'currency' => 'USD'
    )));
$paymentDefinition_1->setName('2nd Payment')
    ->setType('REGULAR')
    ->setFrequency('DAY')
    ->setFrequencyInterval('1')
    ->setCycles('1000')
    ->setAmount(new Currency(array(
        'value' => 30,
        'currency' => 'USD'
    )));

或者在 HTML 表单中给他们一个字符串名称，然后将该名称作为请求对象的属性访问

例如

<form action="/" method="post">
    @csrf
    <input type="number" name="paymentDefinition_0" value="20"><br>
    <input type="number" name="paymentDefinition_1" value="30"><br>
    <button type="submit">Submit</button>
</form>

并相应地访问

$paymentDefinition_0->setName('1stPayment')
    ->setType('REGULAR')
    ->setFrequency('DAY')
    ->setFrequencyInterval('1')
    ->setCycles('1000')
    ->setAmount(new Currency(array(
        'value' => $request->paymentDefinition_0,
        'currency' => 'USD'
    )));
$paymentDefinition_1->setName('2nd Payment')
    ->setType('REGULAR')
    ->setFrequency('DAY')
    ->setFrequencyInterval('1')
    ->setCycles('1000')
    ->setAmount(new Currency(array(
        'value' => $request->paymentDefinition_1,
        'currency' => 'USD'
    )));

希望这可以帮助
