Php 对给定顶级类别的所有子类别禁用特定付款方式

我正试图通过给定的WooCommerce类别slug停用所有子类别的PayPal。目前，我下面的代码只是停用了一个类别的付款方式。是否可以停用所有子类别

<?php
/**
 * Disable payment gateway based on category.
 */
function ace_disable_payment_gateway_category( $gateways ) {
    // Categories that'll disable the payment gateway 
    $category_slugs = array( 'tobacco' );
    $category_ids = get_terms( array( 'taxonomy' => 'product_cat', 'slug' => $category_slugs, 'fields' => 'ids' ) );

    // Check each cart item for given category
    foreach ( WC()->cart->get_cart() as $item ) {
        $product = $item['data'];

        if ( $product && array_intersect( $category_ids, $product->get_category_ids() ) ) {
            unset( $gateways['ppec_paypal'] );
            break;
        }
    }

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

要禁用顶级产品类别子类别的特定支付网关，请使用以下命令：

add_filter( 'woocommerce_available_payment_gateways', 'disable_payment_gateway_subcategory' );
function disable_payment_gateway_subcategory( $payment_gateways ) {
    if ( is_admin() ) return $payment_gateways; // Not on admin

    $taxonomy     = 'product_cat';
    $term_slug    = 'tobacco'; // Main top category
    $term_id      = get_term_by( 'slug', $term_slug, $taxonomy )->term_id; // get term Id
    $children_ids = get_term_children( $term_id, $taxonomy ); // Get all children terms Ids
    array_unshift( $children_ids, $term_id ); // Adding main term Id to the array

    // Check each cart item for given subcategories of a top category
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        $term_ids = wp_get_post_terms( $cart_item['product_id'], $taxonomy, array('fields' => 'ids') );

        if ( array_intersect( $children_ids, $term_ids ) ) {
            unset($payment_gateways['ppec_paypal']);
            break; // stop the loop
        }
    }
    return $payment_gateways;
}

代码进入活动子主题（或活动主题）的functions.php文件。已测试并有效。
适用于其他具有相同问题的用户@LOICTHAZTEC代码由代码部分扩展，以检查单个产品站点是否也是该类别的一部分：

 * Disable payment gateway based on category.
 */
add_filter( 'woocommerce_available_payment_gateways', 'disable_payment_gateway_subcategory' );
function disable_payment_gateway_subcategory( $payment_gateways ) {
    if ( is_admin() ) return $payment_gateways; // Not on admin

    $taxonomy     = 'product_cat';
    $term_slug    = 'tobacco'; // Main top category
    $term_id      = get_term_by( 'slug', $term_slug, $taxonomy )->term_id; // get term Id
    $children_ids = get_term_children( $term_id, $taxonomy ); // Get all children terms Ids
    array_unshift( $children_ids, $term_id ); // Adding main term Id to the array

    // Check on single product site 
    $cateID = wp_get_post_terms( get_the_ID(), $taxonomy, array('fields' => 'ids') );
    if ( array_intersect( $children_ids, $cateID ) ) {
        unset($payment_gateways['ppec_paypal']);
    }

    // Check each cart item for given subcategories of a top category
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        $term_ids = wp_get_post_terms( $cart_item['product_id'], $taxonomy, array('fields' => 'ids') );

        if ( array_intersect( $children_ids, $term_ids ) ) {
            unset($payment_gateways['ppec_paypal']);
            break; // stop the loop
        }
    }
    return $payment_gateways;
        
}

谢谢，但不幸的是它不起作用。将付款方式改为“bacs”也一样。我想这只适用于结帐或购物车？在单一产品页面上也应禁用此选项。单一产品页面上也会激活快速PayPal结账。对不起，我不想占用你的时间，但我对PHP没有你熟悉，通常我是Java开发人员。也许你能救我一天：）哥们！！！它现在工作得很好。非常感谢你！我会接受答案。但还有一个问题：如果我添加了一项“烟草”并去结帐，我的服务器日志会输出一个“408”错误代码，而没有任何进一步的信息——它来自您的代码。有什么想法吗？不过，谢谢你抽出时间@OzzyB。我不明白……你的意思是，如果你添加一个类别为“tobbaco”的项目，你会得到一个错误？我刚刚更新了代码，将“烟草”术语Id包含到术语Id数组中…使用代码（之前的代码也是），WooCommerce存在一些问题。我无法打开WooCommerce仪表板和客户。其他一切都没有问题。这是服务器的输出：
