function wc_stop_order_notification( $email_class ){

    global $post;

    $order = new WC_Order($post->ID);

    $wc_oreder_status = $post->post_status;

    $shiping_method_used_in = $order->get_shipping_method();


    if( $shiping_method_used_in == 'Local Pickup' && $wc_oreder_status == 'wc-completed'){

        remove_action( 'woocommerce_order_status_completed_notification', array( $email_class->emails['WC_Email_Customer_Completed_Order'], 'trigger' ) );
    }
}
add_action( 'woocommerce_email', 'wc_stop_order_notification' ,99);

“woocommerce_email”可能不起作用。改为使用钩子“woocommerce\u order\u status\u completed”。

“woocommerce\u email”可能不起作用。改为使用钩子“woocommerce\u order\u status\u completed”
