如何用printf函数生成含WooCommerce变量的HTML链接？

Looks like you’ve got the right core idea using printf to build your order link, but the issue is you’re passing the static string 'woocommerce' to the first %s placeholder instead of the actual order number. That’s why your link is landing on /view-order/woocommerce/ instead of the correct order-specific page.

Here’s the corrected code that replaces both %s placeholders with the dynamic order number:

<?php 
printf(
    '<a href="https://www.baseclothing.nl/mijn-account/view-order/%s/">https://www.baseclothing.nl/mijn-account/view-order/%s/</a>',
    esc_html( $order->get_order_number() ),
    esc_html( $order->get_order_number() )
); 
?>

Key Fixes Explained: #

• Removed the static 'woocommerce' string and replaced it with esc_html( $order->get_order_number() ) for the first placeholder. Now both the link’s href attribute and the visible text will use the actual order number from your $order object.
• We keep using esc_html() to sanitize the order number—this is a critical best practice to prevent potential XSS vulnerabilities in your output.

Just double-check that the $order variable is a valid WooCommerce Order object when this code runs (for example, that it’s being used in a context where the order is properly initialized, like on an order confirmation page or customer email template).
