基于用户角色和产品类别的货到付款 (COD)

Question

我需要根据用户角色和产品类别在 WooCommerce 中自定义货到付款 (COD)。

要求：

• 默认 COD 是隐藏的
• 当购物车中的产品属于某个类别（类别 1）时，COD 可见
• 具有“x”角色的用户必须始终看到 COD，即使他们的购物车中没有类别 1 产品。

这是我尝试满足上述要求的代码：

function disable_cod($available_gateways)
{

    if (is_admin()) return $available_gateways;

    $role = false;
     //check whether the avaiable payment gateways have Cash on delivery and user is not logged in or he is a user with role customer
    if (isset($available_gateways['cod']) && (current_user_can('customer') || !is_user_logged_in()))
    {
        $role = true;
    }

    foreach (WC()
        ->cart
        ->get_cart() as $cart_item_key => $cart_item)
    {
        $prod_simple = true;
        // Get the WC_Product object
        $product = wc_get_product($cart_item['product_id']);
        // Get the product types in cart (example)
        if ($product->is_product_category('X')) $prod_simple = false;

    }

    if ($prod_simple = $role = true) unset($available_gateways['cod']); // unset 'cod'
    

    return $available_gateways;
}

add_filter('woocommerce_available_payment_gateways', 'disable_cod', 99, 1);

我的语法肯定有问题，但我希望逻辑概念是正确的？有什么建议吗？

Answer 1

您的代码包含一些小错误：

• is_product_category()

  是一个条件标签，在查看产品类别存档时返回 true。使用 has_term() 代替。
• 仅当未满足用户角色时才需要循环浏览购物车。

所以你得到：

function filter_woocommerce_available_payment_gateways( $payment_gateways ) {
    // Not on admin
    if ( is_admin() ) return $payment_gateways;

    // Initialize: flag - default true
    $flag = true;

    // Has certain user role
    if ( current_user_can( 'certain-user-role' ) ) {
        // False
        $flag = false;
    } else {
        // Specific categories: the term name/term_id/slug. Several could be added, separated by a comma
        $categories = array( 63, 15, 'categorie-1' );

        // Isset
        if ( WC()->cart ) {
            // Loop through cart items
            foreach ( WC()->cart->get_cart() as $cart_item ) {
                // Has term (product category)
                if ( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ) {
                    // False, break loop
                    $flag = false;
                    break;
                }
            }
        }
    }

    // True
    if ( $flag ) {
        // Cod
        if ( isset( $payment_gateways['cod'] ) ) {
            // Remove
            unset( $payment_gateways['cod'] );
        }  
    }
    
    return $payment_gateways;
}
add_filter( 'woocommerce_available_payment_gateways', 'filter_woocommerce_available_payment_gateways', 10, 1 );

Answer 2

仅针对特定角色，将其添加到您的 function.php 中：

function custom_enable_cod_for_shop_manager( $available_gateways ) {

// Check if the user is a shop_manager
$user = wp_get_current_user();

if ( in_array( 'shop_manager', (array) $user->roles ) ) {
    // Enable Cash on Delivery for shop_manager
    $available_gateways['cod'] = new WC_Gateway_COD();
}

return $available_gateways;
}

add_filter( 'woocommerce_available_payment_gateways','custom_enable_cod_for_shop_manager' );
