Хотите добавить платежный шлюз PAYUMONEY в плагин Wordpress "Easy Digital Download"

Question

Я хочу создать плагин для WordPress, который позволит легко и просто загружать платежный шлюз PAYUMONEY. Я сделал некоторое кодирование с помощью этой ссылки [1]: https://gist.github.com/amitabhaghosh197/788ef94f874ba6f4fdd0. Внесены некоторые изменения, но они не перенаправляют на payu, а просто переходят на страницу успешного платежа с ожидающим статусом оплаты. Мой код, как показано ниже

<?php
// registers the gateway
function pw_edd_register_gateway($gateways) {
$gateways['payu_money_gateway'] = array('admin_label' => 'PayU Money','checkout_label' => __('PayU Money', 'pw_edd'));
return $gateways;
}
add_filter('edd_payment_gateways', 'pw_edd_register_gateway');
function pw_edd_payu_money_gateway_cc_form() {
// register the action to remove default CC form
return;
}
add_action('edd_payu_money_gateway_cc_form',
'pw_edd_payu_money_gateway_cc_form');
// adds the settings to the Payment Gateways section
function pw_edd_add_settings($settings) {

$payu_settings = array(
    'header' =>array(
        'id' => 'payu_money_gateway_settings',
        'name' => '<strong>' . __( 'PayU Money Gateway Settings', 'pw_edd' ) . '</strong>',
        'desc' => __( 'Configure the gateway settings', 'pw_edd' ),
        'type' => 'header'
    ),
    'merchant_id' => array(
        'id' => 'live_api_key',
        'name' => __( 'Live Merchant Key', 'pw_edd' ),
        'desc' => __( 'Enter your live Merchant key, found in your gateway Account Settings', 'pw_edd' ),
        'type' => 'text',
        'size' => 'regular'
    ),
    'salt_key' => array(
        'id' => 'live_salt_key',
        'name' => __( 'Live Salt Key', 'pw_edd' ),
        'desc' => __( 'Enter your live Salt key, found in your gateway Account Settings', 'pw_edd' ),
        'type' => 'text',
        'size' => 'regular'
    ),
);

return array_merge($settings, $payu_settings);  
}
add_filter('edd_settings_gateways', 'pw_edd_add_settings');
// processes the payment
