Question

我发现这个要点可以隐藏不需要的虚拟产品结帐字段。如果同时存在虚拟产品和实体产品，如何调整它不隐藏字段？我擅长写 WordPress 条件语句，但我很难理解如何编写这个条件语句。

如有任何帮助，我将不胜感激。

<?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;

}

向以下代码添加一个 else 条件，告诉它如果产品不是虚拟的则立即退出。

  // 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
