如果订单中的产品属于 WooCommerce 中的某个类别，如何自动创建帐户

我有一家 WooCommerce 商店，顾客以客人身份结账。我现在想出售一些虚拟产品，在这种情况下我想自动创建一个帐户。

所以我有两个工作代码片段。

• 用于检查购物车中的产品是否属于特定类别（在线）
• 一种是从客人结账时自动创建帐户。

但我不知道如何将这两者结合起来，以便它们一起工作。或者这是一个更好的解决方案？有任何想法吗？

这是我开始使用的两个代码片段，然后尝试将其合并为一个函数。

Source: 使用 WooCommerce 检查购物车项目中的产品类别

add_action('woocommerce_before_cart', 'action_before_cart');
function action_before_cart() {
    $categories   = array('online');
    $has_category = false;

    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        // Check for product categories
        if ( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ) {
            $has_category = true;
            break;
        }
    }

    // Testing output (display a notice)
    if ( $has_category ) { 
        wc_print_notice( sprintf( 'Product category "%s" is in cart!', reset($categories)), 'notice' );
    }
}

Source: 在 Woocommerce 中以编程方式发送重置密码电子邮件通知

function wc_register_guests( $order_id ) {
  // get all the order data
  $order = new WC_Order($order_id);
  
  //get the user email from the order
  $order_email = $order->billing_email;
    
  // check if there are any users with the billing email as user or email
  $email = email_exists( $order_email );  
  $user = username_exists( $order_email );
  
  // if the UID is null, then it's a guest checkout
  if( $user == false && $email == false ){
    
    // random password with 12 chars
    $random_password = wp_generate_password();
    
    // create new user with email as username & newly created pw
    $user_id = wp_create_user( $order_email, $random_password, $order_email );
    
    //WC guest customer identification
    update_user_meta( $user_id, 'guest', 'yes' );
 
    //user's billing data
    update_user_meta( $user_id, 'billing_address_1', $order->billing_address_1 );
    update_user_meta( $user_id, 'billing_address_2', $order->billing_address_2 );
    update_user_meta( $user_id, 'billing_city', $order->billing_city );
    update_user_meta( $user_id, 'billing_company', $order->billing_company );
    update_user_meta( $user_id, 'billing_country', $order->billing_country );
    update_user_meta( $user_id, 'billing_email', $order->billing_email );
    update_user_meta( $user_id, 'billing_first_name', $order->billing_first_name );
    update_user_meta( $user_id, 'billing_last_name', $order->billing_last_name );
    update_user_meta( $user_id, 'billing_phone', $order->billing_phone );
    update_user_meta( $user_id, 'billing_postcode', $order->billing_postcode );
    update_user_meta( $user_id, 'billing_state', $order->billing_state );
 
    // user's shipping data
    update_user_meta( $user_id, 'shipping_address_1', $order->shipping_address_1 );
    update_user_meta( $user_id, 'shipping_address_2', $order->shipping_address_2 );
    update_user_meta( $user_id, 'shipping_city', $order->shipping_city );
    update_user_meta( $user_id, 'shipping_company', $order->shipping_company );

    update_user_meta( $user_id, 'shipping_first_name', $order->shipping_first_name );
    update_user_meta( $user_id, 'shipping_last_name', $order->shipping_last_name );
    update_user_meta( $user_id, 'shipping_method', $order->shipping_method );
    update_user_meta( $user_id, 'shipping_postcode', $order->shipping_postcode );
    update_user_meta( $user_id, 'shipping_state', $order->shipping_state );
    
    // link past orders to this newly created customer
    wc_update_new_customer_past_orders( $user_id );
  }
  
}
 
//add this newly created function to the thank you page
add_action( 'woocommerce_thankyou', 'wc_register_guests', 10, 1 ); 

我不会自动创建帐户。我会确保只要没有帐户就无法下订单。 （如果购物车中存在该特定产品）。

WooCommerce 中已提供帐户的创建和相关操作（例如电子邮件等）。

否则，您将不得不为其编写额外的代码，并且您很快就会发现总是缺少一些选项（例如发送带有用户密码的电子邮件），需要您编写更多的额外代码。简而言之，尽可能保持简单。

But 因为您的问题是关于您自己创建帐户，您可以使用以下代码来完成此操作

• 通过代码中添加的注释标签进行解释
• wp_insert_user()- 将用户插入数据库

function wc_register_guests( $order_id ) {
    // Determines whether the current visitor is a logged in user.
    if( is_user_logged_in() ) return;
    
    // Get $order object
    $order = wc_get_order( $order_id );
    
    // Get the user email from the order
    $order_email = $order->billing_email;

    // Check if there are any users with the billing email as user or email
    $email = email_exists( $order_email );  
    $user = username_exists( $order_email );

    // If the UID is null, then it's a guest checkout (new user)
    if( $user == false && $email == false ) {
        // Check on category ( multiple categories can be entered, separated by a comma )
        $categories = array( 'online', 'categorie-1' );

        // Flag
        $has_category = false;
        
        // Loop through order items
        foreach ( $order->get_items() as $item_key => $item ) {
            if ( has_term( $categories, 'product_cat', $item['product_id'] ) ) {
                $has_category = true;
                break;
            }
        }
        
        // True
        if ( $has_category ) {
            // Random password with 12 chars
            $random_password = wp_generate_password();
            
            // Firstname
            $first_name = $order->get_billing_first_name();
            
            // Lastname
            $last_name = $order->get_billing_last_name();
            
            // Role
            $role = 'customer';

            // Create new user with email as username, newly created password and userrole          
            $user_id = wp_insert_user(
                array(
                    'user_email' => $order_email,
                    'user_login' => $order_email,
                    'user_pass'  => $random_password,
                    'first_name' => $first_name,
                    'last_name'  => $last_name,
                    'role'       => $role,
                )
