Add product name in subject of WooCommerce new order email notification

Question

I want to change the subject line of the email I send to the store owner to put the product name in it. I saw this code to put the customer's name in front How can I adjust this code to include the product name

/*
 * Place it in the theme’s functions.php or custom plug-in
 *
 * Topic filter:
 *woocommerce_email_subject_new_order
 *woocommerce_email_subject_customer_processing_order
 *woocommerce_email_subject_customer_completed_order
 *woocommerce_email_subject_customer_invoice
 *woocommerce_email_subject_customer_note
 *woocommerce_email_subject_low_stock
 *woocommerce_email_subject_no_stock
 *woocommerce_email_subject_backorder
 *woocommerce_email_subject_customer_new_account
 *woocommerce_email_subject_customer_invoice_paid
 **/
add_filter('woocommerce_email_subject_new_order', 'change_admin_email_subject', 1, 2);

function change_admin_email_subject( $subject, $order ) {
    global $woocommerce;

    $blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);

    $subject = sprintf( '[%s] New customer order (# %s) from name %s %s', $blogname, $order->id, $order->billing_first_name, $order->billing_last_name ) ;

    return $subject;
}

Maybe we just need to make changes here

$subject = sprintf( '[%s] New customer order (# %s) from name %s %s', $blogname, $item-> ;get_name, $order->billing_first_name, $order->billing_last_name );

    return $subject;
}

Your actual code is outdated... To add the purchased product name (and quantity) to the subject of the new order email notification sent to the admin, use the following code:

add_filter('woocommerce_email_subject_new_order', 'change_email_subject_new_order', 10, 2);
function change_email_subject_new_order( $formatted_subject, $order ) {
    $products = array(); // 初始化

    // 循环遍历订单项目
    foreach( $order->get_items() as $item ){
        // 将格式化的产品名称和数量添加到数组中
        $products[] = sprintf( '%s × %d', $item->get_name(), $item->get_quantity() );
    }

    $count    = count($products); // 产品数量
    $products = implode(', ', $products); // 将数组转换为字符串

    return sprintf( 
        __('[%s] 新客户订单（＃%s），%s，来自%s%s', 'woocommerce'), 
        wp_specialchars_decode(get_option('blogname'), ENT_QUOTES), $order->get_order_number(), 
        sprintf( _n('产品（%s）', '产品（%s）', $count, 'woocommerce'), $products, $products ),
        $order->get_billing_first_name(), $order->get_billing_last_name() 
    );
}

Place the code in your child theme’s functions.php file (or in a plugin). It has been tested and works fine.
