从 Woocommerce 设置电子邮件列表中删除未使用的电子邮件

Question

几天前，我询问了如何在 WooCommerce 中重命名自定义电子邮件模板。现在我有一些我不需要的电子邮件模板的问题，我想完全隐藏这些模板。我怎样才能做到这一点？我在 SO 和 Google 上搜索过，但找不到教程。

更新：正确的解决方案是使用woocommerce_email_classes过滤钩子定位在WC_Emails类中：

add_filter( 'woocommerce_email_classes', 'remove_specific_email_classes', 10, 1 );
function remove_specific_email_classes( $emails ) {
    unset($emails['WC_Email_New_Order']);
    unset($emails['WC_Email_Cancelled_Order']);
    unset($emails['WC_Email_Failed_Order']);
    unset($emails['WC_Email_Customer_On_Hold_Order']);
    unset($emails['WC_Email_Customer_Processing_Order']);
    unset($emails['WC_Email_Customer_Completed_Order']);
    unset($emails['WC_Email_Customer_Refunded_Order']);
    unset($emails['WC_Email_Customer_Invoice']);
    unset($emails['WC_Email_Customer_Note']);
    unset($emails['WC_Email_Customer_Reset_Password']);
    unset($emails['WC_Email_Customer_New_Account']);

    return $emails;
}

代码进入您的活动子主题（活动主题）的 function.php 文件中。经过测试并且可以工作。

以下official Woocommerce documented 挂钩函数将删除通知操作挂钩：

add_action( 'woocommerce_email', 'unhook_those_pesky_emails' );
function unhook_those_pesky_emails( $email_class ) {

    //Hooks for sending emails during store events
    remove_action( 'woocommerce_low_stock_notification', array( $email_class, 'low_stock' ) );
    remove_action( 'woocommerce_no_stock_notification', array( $email_class, 'no_stock' ) );
    remove_action( 'woocommerce_product_on_backorder_notification', array( $email_class, 'backorder' ) );

    // New order emails
    remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
    remove_action( 'woocommerce_order_status_pending_to_completed_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
    remove_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
    remove_action( 'woocommerce_order_status_failed_to_processing_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
    remove_action( 'woocommerce_order_status_failed_to_completed_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
    remove_action( 'woocommerce_order_status_failed_to_on-hold_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );

    // Processing order emails
    remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );
    remove_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );

    // Completed order emails
    remove_action( 'woocommerce_order_status_completed_notification', array( $email_class->emails['WC_Email_Customer_Completed_Order'], 'trigger' ) );

    // Note emails
    remove_action( 'woocommerce_new_customer_note_notification', array( $email_class->emails['WC_Email_Customer_Note'], 'trigger' ) );
}

这是我的解决方案。我不确定哪个更好？

add_filter( 'woocommerce_email_classes', 'remove_unused_emails', 15 );
function remove_unused_emails( $email_classes ) {

    //Unset unused email templates
    unset( $email_classes['WC_Email_Customer_Reset_Password'] );
    unset( $email_classes['WC_Email_Customer_New_Account'] );
    unset( $email_classes['WC_Email_Customer_On_Hold_Order'] );
    unset( $email_classes['WC_GZD_Email_Customer_New_Account_Activation'] );
    unset( $email_classes['WC_GZD_Email_Customer_Revocation'] );
    unset( $email_classes['WC_GZD_Email_Customer_Ekomi'] );
    unset( $email_classes['WC_GZD_Email_Customer_Trusted_Shops'] );

    return $email_classes;

}
