Woocommerce：覆盖现有电子邮件所需的登录名。将订单添加到用户帐户

Question

Woocommerce设置：

• 访客结帐已禁用。
• 启用结帐时创建帐户（自动生成用户和密码）

如果用户已注册。但尚未登录。 结帐错误 “已经使用您的电子邮件地址注册了一个帐户。请登录。”

我该如何覆盖 完成订单，并将订单绑定到现有帐户。 提示用户下次登录以加快结帐速度

找不到任何可以做到的代码片段或模块

还没有。乐于回报。

对此没有钩子。您可能需要修改WC核心中的process_customer函数（plugins / woocommerce / includes / class-wc-checkout.php）。Line＃935-请记住，不建议您编辑核心（更新后，您的更改将会丢失）

protected function process_customer( $data ) {
        $customer_id = apply_filters( 'woocommerce_checkout_customer_id', get_current_user_id() );

        if ( ! is_user_logged_in() && ( $this->is_registration_required() || ! empty( $data['createaccount'] ) ) ) {
            $username    = ! empty( $data['account_username'] ) ? $data['account_username'] : '';
            $password    = ! empty( $data['account_password'] ) ? $data['account_password'] : '';

                        if(email_exists($data['billing_email'])){
                        $creds = array();
                        $creds['user_login'] = $user_login;
                        $creds['user_password'] = $user_password;
                        $creds['remember'] = true;

                        $user = wp_signon($creds, false);

                        $customer_id = $user->ID;

                        wp_set_current_user($customer_id, $user_login);
                        wp_set_auth_cookie($customer_id, true, false);
                        do_action('wp_login', $user_login);
                        }else{
                        $customer_id = wc_create_new_customer( $data['billing_email'], $username, $password );
                        }

            if ( is_wp_error( $customer_id ) ) {
                throw new Exception( $customer_id->get_error_message() );
            }

            wp_set_current_user( $customer_id );
            wc_set_customer_auth_cookie( $customer_id );

            // As we are now logged in, checkout will need to refresh to show logged in data.
            WC()->session->set( 'reload_checkout', true );

            // Also, recalculate cart totals to reveal any role-based discounts that were unavailable before registering.
            WC()->cart->calculate_totals();
        }

        // On multisite, ensure user exists on current site, if not add them before allowing login.
        if ( $customer_id && is_multisite() && is_user_logged_in() && ! is_user_member_of_blog() ) {
            add_user_to_blog( get_current_blog_id(), $customer_id, 'customer' );
        }

        // Add customer info from other fields.
        if ( $customer_id && apply_filters( 'woocommerce_checkout_update_customer_data', true, $this ) ) {
            $customer = new WC_Customer( $customer_id );

            if ( ! empty( $data['billing_first_name'] ) ) {
                $customer->set_first_name( $data['billing_first_name'] );
            }

            if ( ! empty( $data['billing_last_name'] ) ) {
                $customer->set_last_name( $data['billing_last_name'] );
            }

            // If the display name is an email, update to the user's full name.
            if ( is_email( $customer->get_display_name() ) ) {
                $customer->set_display_name( $data['billing_first_name'] . ' ' . $data['billing_last_name'] );
            }

            foreach ( $data as $key => $value ) {
                // Use setters where available.
                if ( is_callable( array( $customer, "set_{$key}" ) ) ) {
                    $customer->{"set_{$key}"}( $value );

                    // Store custom fields prefixed with wither shipping_ or billing_.
                } elseif ( 0 === stripos( $key, 'billing_' ) || 0 === stripos( $key, 'shipping_' ) ) {
                    $customer->update_meta_data( $key, $value );
                }
            }

            /**
             * Action hook to adjust customer before save.
             *
             * @since 3.0.0
             */
            do_action( 'woocommerce_checkout_update_customer', $customer, $data );

            $customer->save();
        }

        do_action( 'woocommerce_checkout_update_user_meta', $customer_id, $data );
    }

如果您启用了允许客户在结帐时登录，那么将出现从结帐页面登录的选项。
