停止免费订单的 WooCommerce 管理员电子邮件通知

Question

如果订单值为 [=12=].00

，我想停止 woocommerce 电子邮件通知

我使用了这段代码：

function restrict_admin_new_order_mail( $recipient, $order ) {
    if( $order->get_total() === '0.00' ) {
        return;
    } else {
        return $recipient;
    }
}
add_filter('woocommerce_email_recipient_new_order', 'restrict_admin_new_order_mail', 1, 2);

代码有效，但我遇到了这个致命错误，所有电子邮件选项在 Woocommerce 设置中都消失了（参见随附的屏幕截图）。

Answer 1

看看。

add_filter( 'woocommerce_email_recipient_customer_completed_order', 'wc_disable_customer_order_email_if_free', 10, 2 );
  
function wc_disable_customer_order_email_if_free( $recipient, $order ) {
    $page = $_GET['page'] = isset( $_GET['page'] ) ? $_GET['page'] : '';
    if ( 'wc-settings' === $page ) {
        return $recipient; 
    }
    if ( (float) $order->get_total() === '0.00' ) $recipient = '';
    return $recipient;
}

Answer 2

我删除了（浮动）以使其工作，此代码停止了管理员的通知电子邮件

add_filter( 'woocommerce_email_recipient_new_order', 'wc_disable_customer_order_email_if_free', 10, 2 );

function wc_disable_customer_order_email_if_free( $recipient, $order ) {
    $page = $_GET['page'] = isset( $_GET['page'] ) ? $_GET['page'] : '';
    if ( 'wc-settings' === $page ) {
        return $recipient; 
    }
    if ( $order->get_total() === '0.00' ) $recipient = '';
    return $recipient;
}

Answer 3

为避免此错误，您需要在函数开头添加以下简单行：

if ( ! is_a( $order, 'WC_Order' ) ) return $recipient;

我也重新审视了你的代码......试试这个：

add_filter('woocommerce_email_recipient_new_order', 'restrict_admin_new_order_mail', 1, 2);
function restrict_admin_new_order_mail( $recipient, $order ) {
    if ( ! is_a( $order, 'WC_Order' ) ) 
        return $recipient;

    if( $order->get_total() > 0 ) {
        return $recipient;
    } else {
        return '';
    }
}

代码进入活动子主题（或活动主题）的 functions.php 文件。现在应该可以使用了。
