我已经将stripe PHP集成到woocommerce中，但当试图处理付款时，我得到了这个错误
没有这样的付款方式：自定义
下面是代码

<?php
/**
 * Plugin Name: Stripe-PHP-integration
 * Description: PHP API Integration For Wordpress
 * Author: Null
 * Version: 1.0
**/

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

require_once 'stripe/init.php';

use Stripe\Stripe;

add_action('init', function() {

    Stripe::setApiKey('sk_test_....');
    Stripe::setClientId('pk_test_....');

});

add_action('plugins_loaded', 'init_custom_gateway_class');
function init_custom_gateway_class(){

    class WC_Gateway_Custom extends WC_Payment_Gateway {

        /**
         * Constructor for the gateway.
         */
        public function __construct() {

            $this->id                 = 'custom';
            $this->icon               = apply_filters('woocommerce_custom_gateway_icon', '');
            $this->has_fields         = false;
            $this->method_title       = __( 'Stripe PHP API Integration For WooCommerce', $this->domain );
            $this->method_description = __( 'Allows payments using Stripe PHP API', $this->domain );

            // Load the settings.
            $this->init_form_fields();
            $this->init_settings();

            // Define user set variables
            $this->title        = $this->get_option( 'title' );
            $this->description  = $this->get_option( 'description' );
            $this->instructions = $this->get_option( 'instructions', $this->description );
            $this->order_status = $this->get_option( 'order_status', 'pending' );
            

            // Actions
            add_action( 'woocommerce_update_options_payment_gateways_' . $this->id, array( $this, 'process_admin_options' ) );
            add_action( 'woocommerce_thankyou_' . $this->id, array( $this, 'thankyou_page' ) );

            // Customer Emails
            add_action( 'woocommerce_email_before_order_table', array( $this, 'email_instructions' ), 10, 3 );
            
            add_action('wp_enqueue_scripts', array($this, 'enqueue_styles'));
            

        }

字符串
它与这一部分有关，具体来说就是$this->id = 'custom';
因为当我删除它时，我得到错误-您为'payment_method'传递了一个空字符串。我们假设空值是试图取消设置参数;但是'payment_method'无法取消设置。您应该从请求中删除'payment_method'或提供非空值。
当我检查条带日志时，我可以看到正在进行请求，但付款对象有问题。
下面是process_order函数

public function process_payment( $order_id ) {

    $order = wc_get_order( $order_id );

    $status = 'wc-' === substr( $this->order_status, 0, 3 ) ? substr( $this->order_status, 3 ) : $this->order_status;
    
    $payment_intent = \Stripe\PaymentIntent::create(array(
    'amount'   => $order->get_total() * 100,
    'currency' => strtolower( get_woocommerce_currency() ),
    'payment_method' => $order->get_payment_method(),
    'confirmation_method' => 'manual',
    'confirm' => true,
     ));

    // Set order status
    $order->update_status( $status, __( 'Checkout with custom payment. ', $this->domain ) );

    // or call the Payment complete
    // $order->payment_complete();

    // Remove cart
    WC()->cart->empty_cart();

    // Return thankyou redirect
    return array(
        'result'    => 'success',
        'redirect'  => $this->get_return_url( $order )
    );
}
