WooCommerce - 条件语句删除不需要的结帐字段

Question

我发现此要点隐藏虚拟产品的不需要的结账字段。如果有虚拟产品和实物产品，我如何调整它以便不隐藏字段？我擅长编写WordPress条件语句，但我无法理解如何编写此条款。

我希望有任何帮助。

<?php 

add_filter('woocommerce_checkout_fields' , 'woo_remove_billing_checkout_fields'); 

/** 
* Remove unwanted checkout fields 
* 
* @return $fields array 
*/ 
function woo_remove_billing_checkout_fields($fields) { 

    if(woo_cart_has_virtual_product() == true) { 
     unset($fields['billing']['billing_company']); 
     unset($fields['billing']['billing_address_1']); 
     unset($fields['billing']['billing_address_2']); 
     unset($fields['billing']['billing_city']); 
     unset($fields['billing']['billing_postcode']); 
     unset($fields['billing']['billing_country']); 
     unset($fields['billing']['billing_state']); 
     unset($fields['billing']['billing_phone']); 
     unset($fields['order']['order_comments']); 
     unset($fields['billing']['billing_address_2']); 
     unset($fields['billing']['billing_postcode']); 
     unset($fields['billing']['billing_company']); 
     unset($fields['billing']['billing_city']); 
    } 

    return $fields; 
} 

/** 
* Check if the cart contains virtual product 
* 
* @return bool 
*/ 
function woo_cart_has_virtual_product() { 

    global $woocommerce; 

    // By default, no virtual product 
    $has_virtual_products = false; 

    // Default virtual products number 
    $virtual_products = 0; 

    // Get all products in cart 
    $products = $woocommerce->cart->get_cart(); 

    // Loop through cart products 
    foreach($products as $product) { 

     // Get product ID and '_virtual' post meta 
     $product_id = $product['product_id']; 
     $is_virtual = get_post_meta($product_id, '_virtual', true); 

     // Update $has_virtual_product if product is virtual 
     if($is_virtual == 'yes') 
     $virtual_products += 1; 
    } 

    if(count($products) == $virtual_products) 
    $has_virtual_products = true; 

    return $has_virtual_products; 

}

将下面的代码添加到下面的代码中，该代码告诉它如果产品不是虚拟的，立即释放。

// Update $has_virtual_product if product is virtual 
    if($is_virtual == 'yes') 
     $virtual_products += 1; 
    else 
     return false; // Cart contains both type of products, bail out immediately
