以编程方式更改新订单、取消订单和失败订单 WooCommerce 通知的电子邮件

Question

当您进入 WooCommerce->设置->电子邮件时，您可以设置用于新订单、失败订单、取消订单等的电子邮件地址。

我正在尝试了解如何以编程方式更改所有这些电子邮件，因此我创建了一个带有输入字段和提交按钮的小模板，以一次更改所有电子邮件，但唯一更改的电子邮件地址是电子邮件地址发件人选项（WooCommerce->设置->电子邮件页面底部的设置），而不是新订单、取消订单和失败订单的选项。

检查可能的钩子，我认为以下代码应该可以解决问题：

function change_notification_email_callback() {
    // Log form data for debugging
    error_log( print_r( $_POST, true ) );

    if ( isset( $_POST['new_notification_email'] ) && ! empty( $_POST['new_notification_email'] ) ) {
        $new_email = sanitize_email( $_POST['new_notification_email'] );

        // Log current value of woocommerce_new_order_recipient option
        $old_recipient_email = get_option( 'woocommerce_new_order_recipient' );
        error_log( 'Old Recipient Email: ' . $old_recipient_email );

        // Update the notification email
        update_option( 'woocommerce_email_from_address', $new_email );
        update_option( 'woocommerce_new_order_email', $new_email );
        update_option( 'woocommerce_cancelled_order_email', $new_email );
        update_option( 'woocommerce_failed_order_email', $new_email );

        // Log updated value of woocommerce_new_order_recipient option
        $updated_recipient_email = get_option( 'woocommerce_new_order_recipient' );
        error_log( 'Updated Recipient Email: ' . $updated_recipient_email );

        // Log updated value of woocommerce_cancelled_order_recipient option
        $updated_recipient_email_cancelled = get_option( 'woocommerce_cancelled_order_recipient' );
        error_log( 'Updated Recipient Email for cancelled: ' . $updated_recipient_email_cancelled );

        // Set success message
        $message = 'Notification email changed successfully.';
        $notice_type = 'success';
    } else {
        // Set error message
        $message = 'Failed to change notification email. Please enter a valid email.';
        $notice_type = 'error';
    }
    
    // Set admin notice
    add_flash_notice( $message, $notice_type );

    // Redirect back to the WooCommerce dashboard page after email change
    wp_redirect( admin_url( 'admin.php?page=wc-dashboard' ) );
    exit;
}

再次强调，在 // 更新通知电子邮件下，只有第一个 update_option 有效，即使日志显示所有实例都已更改（woocommerce_email_from_address、woocommerce_new_order_email 等），甚至在 wp_options 表中查找这些字段，它们也显示已更新，但是当我检查 WooCommerce->设置->电子邮件页面时，这些仍然没有变化（下图显示了我的意思）。我做了一个测试来下订单，以确保它不是缓存或其他东西，但它会发送到那里的任何电子邮件。有谁知道我还可以尝试什么？

您没有使用正确的“新订单”、“已取消订单”和“失败订单”选项键。对于这 3 个选项，每个选项都是一组设置……

重要提示：您将需要仅一次，为这 3 个通知中的每一个手动设置一封新电子邮件并更新以创建设置选项。完成后，您的数据库中的 wp_options 下将包含以下内容：

完成后，您可以使用以下修改后的代码：

function change_notification_email_callback() {
    if ( isset( $_POST['new_notification_email'] ) && ! empty( $_POST['new_notification_email'] ) ) {
        $new_email = sanitize_email( $_POST['new_notification_email'] );

        // Array of option keys for email settings
        $email_setting_keys = array(
            'woocommerce_new_order_settings'       => __('New order'),
            'woocommerce_cancelled_order_settings' => __('Cancelled order'),
            'woocommerce_failed_order_settings'    => __('Failed order'),
        );
        $updated = array(); // Initializing
    
        // Loop through the emails settings keys
        foreach ( $email_setting_keys as $key => $label ) {
            $settings = get_option( $key, array() ); // Get option settings array for the current notification

            if ( ! empty($settings) && isset($settings['recipient']) ) {
                $settings['recipient'] = $new_email; // change recipient with the new email 
                update_option( $key, $settings ); // Update/save settings for the current notification
                $updated[] = $label; // Tag as updated
            }
        }

        // Update the "from Address" email
        update_option( 'woocommerce_email_from_address', $new_email );
        $updated[] = __('From Address'); // Tag as updated

        // Set success message
        $message = sprintf( __('Email changed successfully for "%s" notifications.' ), implode('", "', $updated) );
        $notice_type = 'success';
    } else {
        // Set error message
        $message = __('Failed to change notification email. Please enter a valid email.');
        $notice_type = 'error';
    }
    add_flash_notice( $message, $notice_type ); // Set admin notice

    // Redirect back to the WooCommerce dashboard page after email change
    wp_redirect( admin_url( 'admin.php?page=wc-dashboard' ) );
    exit();
}

代码位于子主题的functions.php 文件中（或插件中）。应该可以。
