在WooCommerce中的电子邮件中重复下面的订单项目名称

Question

我有一个与woocommerce_order_item_name挂钩的函数，用于在项目名称下添加下拉项目和回序项的通知：

add_filter( 'woocommerce_order_item_name', 'custom_order_item_notices', 10, 2 );
function custom_order_item_notices( $item_name, $item ) {
    if ( is_admin() )
        return;
    $echoed = false;

    if ( is_cart() || is_checkout() || is_wc_endpoint_url( 'view-order' ) ) {

        $backorder_qty = 0;
        $product = $item->get_product();

        $DID = strtoupper(get_post_meta($item['product_id'] , 'direct-dispatch', true));
        if ($DID) {
            switch ($DID) {
                case 'BEE':
                    echo $item_name . '<small style="display: block;color: grey;">These items will be 
sent directly from the supplier to your specified delivery address. Please allow 3-5 working days for 
delivery. <a target="_blank" href="/delivery/#direct-despatch">Click here</a> for more info.</small>';
                    $echoed = true;
                    break;
            }
        }

        if (get_post_meta($item->get_order_id(), 'split-order-type', true) == 'BKO') {
            echo $item_name . '<small style="display: block;color: grey;">More stock is on it’s way! Please allow 5-10 working days for delivery. <a target="_blank" href="/delivery/#backorders">Click here</a> for more info.</small>';
            $echoed = true;
        }
    }

    if (!$echoed) echo $item_name;
}

我有一个问题，我无法解释在所有的电子邮件模板显示订单项目。

问题是订单项名称在order表下再次重复。

请参阅以下输出图片：

很明显，我的功能出了点问题，但是经过几个小时的努力，我还是不知道输出是从哪里来的，所以我们会非常感谢你的帮助和见解。

你使用echo和return，我相信这会解决你的问题

function custom_order_item_notices( $item_name, $item ) {
    if ( is_admin() )
        return;

    if ( is_cart() || is_checkout() || is_wc_endpoint_url( 'view-order' ) ) {

        $backorder_qty = 0;
        $product = $item->get_product();

        $DID = strtoupper( get_post_meta($item['product_id'] , 'direct-dispatch', true) );

        $DID = 'BEE';

        if ( $DID ) {
            switch ( $DID ) {
                case 'BEE':
                    $item_name .= '<small style="display: block;color: grey;">These items will be sent directly from the supplier to your specified delivery address. Please allow 3-5 working days for delivery. <a target="_blank" href="/delivery/#direct-despatch">Click here</a> for more info.</small>';
                    break;
            }
        }

        if ( get_post_meta( $item->get_order_id(), 'split-order-type', true) == 'BKO' ) {
            $item_name .= '<small style="display: block;color: grey;">More stock is on it’s way! Please allow 5-10 working days for delivery. <a target="_blank" href="/delivery/#backorders">Click here</a> for more info.</small>';
        }
    }

    return $item_name;
}
add_filter( 'woocommerce_order_item_name', 'custom_order_item_notices', 10, 2 );
