woocommerce：禁用某些类别的付款

Question

我需要在woocommerce网站上禁用某些类别的付款。到目前为止，我已经找到了此代码，该代码仅适用于1类。有谁知道如何使它适用于多个类别？谢谢

<?php
/*
 * A simple filter to disable a user-specified payment gateway when a product with a user-specified category is added to the shopping cart
 *  - Note:  If multiple products are added and only one has a matching category, it will remove the payment gateway
 * Requires:
 *    payment_NAME : One of the five hardcoded Woocommerce standard types of payment gateways - paypal, cod, bacs, cheque or mijireh_checkout
 *    category_ID :   The ID of the category for which the gateway above will be removed.  Get the ID by clicking on the category under Products -> Categories and reading the "tag_ID" in the address bar
 *                             i.e. http://ubuntu.humble.lan/wp-admin/edit-tags.php?action=edit&taxonomy=product_cat&tag_ID=20&post_type=product <-- the tag_ID is 20

function filter_gateways($gateways){

$payment_NAME = 'paypal'; // <--------------- change this
$category_ID = '20';  // <----------- and this

 global $woocommerce;

 foreach ($woocommerce->cart->cart_contents as $key => $values ) {
    // Get the terms, i.e. category list using the ID of the product
    $terms = get_the_terms( $values['product_id'], 'product_cat' );
    // Because a product can have multiple categories, we need to iterate through the list of the products category for a match
    foreach ($terms as $term) {
        // 20 is the ID of the category for which we want to remove the payment gateway
        if($term->term_id == $category_ID){
               unset($gateways[$payment_NAME]);
                   // If you want to remove another payment gateway, add it here i.e. unset($gateways['cod']);
                    break;
          }
        break;

您可以将上面提供的代码修改为以下代码，它应该可以正常工作：

function filter_gateways($gateways){

    global $woocommerce;

    foreach ($woocommerce->cart->cart_contents as $key => $values ) {

        // ID(s) of the category we want to remove gateways from
        $category_ids = array( 12,9 );

        // Get the terms, i.e. category list using the ID of the product
        $terms = get_the_terms( $values['product_id'], 'product_cat' );

        // Because a product can have multiple categories, we need to iterate through the list of the products category for a match
        foreach ($terms as $term) {

            if(in_array($term->term_id,$category_ids)){

                // If you have additional items from a non-restricted category in the cart with a restricted category product the only payment option available for all cart items will be the gateway(s) that haven't been unset.
                // WARNING: If you unset all the gateways users will get a "Sorry, it seems that there are no available payment methods for your state. Please contact us if you require assistance or wish to make alternate arrangements." when trying to checkout!
                unset($gateways['cod']);
                unset($gateways['bacs']);
                unset($gateways['cheque']);
                break;
            }
        break;
        }

    }
    return $gateways;
}
add_filter('woocommerce_available_payment_gateways','filter_gateways');

注意：请记住，如果购物车中有非受限类别的其他商品中包含受限类别产品，则结帐期间所有购物车商品可用的唯一付款选项将是尚未设置的网关。
