有条件的付款网关

Question

我需要条件付款网关代码...

我的网站上有一个钱包系统，我想要有条件的付款网关进行验证和结帐...

如果账单金额为₹1000 /-，并且客户希望从钱包中支付部分金额，则剩余金额应通过在线系统支付，而不用货到付款... 我该如何解决...建议我输入新代码，因为我的代码无法正常工作

function woo_disable_cod($available_gateways)
{
    //check whether the avaiable payment gateways have Cash on delivery and user is not logged in or he is a user with role customer
    $current_user = wp_get_current_user(); 
    if (isset($available_gateways['cod']) && ((current_user_can('customer') && $current_user->user_firstname == 'Peter') || !is_user_logged_in())) {
        //remove the paypal payment gateway from the available gateways.
        unset($available_gateways['paypal']);
    }
    return $available_gateways;
}
