Disabling Amazon Payments Advanced method from WooCommerce checkout page - php

Question

I'm trying to disable a couple of payment gateways based on a user's role. The function & hook I found works on the Paypal method but not Amazon Payments Advanced. Here's my code:
function wk_disable_gateways( $available_gateways ) {
global $woocommerce;
$wholesale_cust = check_user_role( array( 'wholesale', 'orig-wholesale' ) );
if ( isset( $available_gateways['paypal'] ) && $wholesale_cust ) {
unset( $available_gateways['paypal'] );
}
if ( isset( $available_gateways['amazon_payments_advanced'] ) && $wholesale_cust ) {
unset( $available_gateways['amazon_payments_advanced'] );
}
return $available_gateways;
}
add_filter( 'woocommerce_available_payment_gateways', 'wk_disable_gateways' );
The "Pay with Amazon" code is still running on the checkout page. Any ideas?

This is not the best solution, but I have not been able to find a more viable answer.
First off I did what you did and disabled all gateways expect the one I wanted the user to use. In my case I only want someone to check out with the nmigateway.
This goes inside of your theme functions.php
add_filter( 'woocommerce_available_payment_gateways', 'filter_gateways', 1);
function filter_gateways( $gateways ){
global $woocommerce;
// what products you wish to exculde
$nonPPproducts = array(1457, 1447, 479); // LIST YOUR PRODUCT IDS HERE
foreach ($woocommerce->cart->cart_contents as $key => $values ) {
if ( in_array( $values['product_id'], $nonPPproducts ) ) {
foreach ( $gateways as $gateway_key => $gateway ) {
if ( $gateway_key !== 'nmipay' ) {
unset( $gateways[ $gateway_key ] );
}
}
}
}
return $gateways;
}
Next here is the part that makes this not the best solution editing the plugins source code.
Change the following two functions inside of the plugins/woocommerce-gateway-amazon-payments-advanced/amazon-payments-advanced.php
/**
* Checkout Button
*
* Triggered from the 'woocommerce_proceed_to_checkout' action.
*/
function checkout_button() {
global $woocommerce;
// what products you wish to exculde
$nonPPproducts = array(1457, 1447, 479); // LIST YOUR PRODUCT IDS HERE
foreach ($woocommerce->cart->cart_contents as $key => $values ) {
if ( in_array( $values['product_id'], $nonPPproducts ) ) {
$disable_button = true;
}
}
if(!isset($disable_button) && $disable_button !== true ){
?><div id="pay_with_amazon"></div><?php
}
}
/**
* Checkout Message
*/
function checkout_message() {
global $woocommerce;
// what products you wish to exculde
$nonPPproducts = array(1457, 1447, 479); // LIST YOUR PRODUCT IDS HERE
foreach ($woocommerce->cart->cart_contents as $key => $values ) {
if ( in_array( $values['product_id'], $nonPPproducts ) ) {
$disable_button = true;
}
}
if(!isset($disable_button) && $disable_button !== true ){
if ( empty( $this->reference_id ) ) {
echo '<div class="woocommerce-info info"><div id="pay_with_amazon"></div> ' . apply_filters( 'woocommerce_amazon_pa_checkout_message', __( 'Have an Amazon account?', 'woocommerce-gateway-amazon-payments-advanced' ) ) . '</div>';
}
}
}
Keep in mind that when the plugin is updated all of your changes will be lost.
