Question

我正在为WooCommerce插件编写扩展程序，我遇到了多次付款的问题。我想使用PayPal，我认为最好的方法是实施PayPal自适应支付。我已经阅读了PayPal和WooCommerce的文档，但我无法理解。

我已经定义了新的支付网关，正如文件所述： http://docs.woothemes.com/document/payment-gateway-api/

class WC_Gateway_Adaptive_PayPal extends WC_Payment_Gateway {

public $environment = 'sandbox';

public function __construct() {

    $this->notify_url = str_replace( 'https:', 'http:', add_query_arg( 'wc-api', 'WC_Gateway_Adaptive_Paypal', home_url( '/' ) ) );

    $this->id = 'adaptive_paypal';
    $this->has_fields = false;
    $this->method_title = 'PayPal';
    $this->method_description = 'Handle payment with many receivers (up to 5)';

    $this->init_form_fields();
    $this->init_settings();

    $this->title = $this->get_option( 'title' );

    add_action( 'woocommerce_update_options_payment_gateways_'.$this->id, array( $this, 'process_admin_options' ) );

}

public function init_form_fields() {

    $this->form_fields = array(
        'enabled' => array(
            'title' => __( 'Enable/Disable', 'wpgmpc' ),
            'type' => 'checkbox',
            'label' => __( 'Enable Adaptive PayPal Payment', 'wpgmpc' ),
            'default' => 'yes'
        ),
        'title' => array(
            'title' => __( 'Title', 'wpgmpc' ),
            'type' => 'text',
            'description' => __( 'This controls the title which the user sees during checkout.', 'wpgmpc' ),
            'default' => __( 'PayPal', 'wpgmpc' ),
            'desc_tip'      => true,
        ),
        'description' => array(
            'title' => __( 'Customer Message', 'wpgmpc' ),
            'type' => 'textarea',
            'default' => ''
        ),
        'percentage' => array(
            'title' => __( 'Fee', 'wpgmpc' ),
            'type' => 'number',
            'description' => __( 'Decide how much you want to take from each payment in %', 'wpgmpc' ),
            'desc_tip'      => true,
            'default' => '0'
        ),
        'receiver_email' => array(
            'title' => __( 'Receiver Email', 'woocommerce' ),
            'type'          => 'email',
            'description' => __( 'If this differs from the email entered above, input your main receiver email for your PayPal account. This is used to validate IPN requests.', 'woocommerce' ),
            'default' => '',
            'desc_tip'      => true,
            'placeholder'   => 'you@youremail.com'
        ),
    );

}

public function process_payment( $order_id ) {

}

}

但根据在WooCommerce中实施的默认PayPal付款，它真的搞砸了。

我知道： - 我必须为PayKey调用API - 我必须使用cURL

我不知道如何将用户重定向到PayPal的付款页面，甚至不知道如何在WooCommerce Gateway API中获取此PayKey。我使用了一些我在SO上找到的片段，但它们根本不起作用。

我将不胜感激任何帮助。谢谢！

编辑：现在我注意到我可以在process_payment方法中从WordPress重定向到自定义URL！但我仍然不知道如何实施IPN。当我收到PayKey时，我可以用它重定向到url？
