Add in meta information

I found this:

<?php
if ( !empty($item[‘product’]) && $location = get_post_meta( $item[‘product’]->id, ‘Location’, true ) ) {
echo ‘<div class=”product-location”>Location: ‘.$location.'</div>’;
}
?>

But when I replaced $location with my meta which is order_card_message it doesn’t work. What am I doing wrong?

Hi! The code snippet you found looks like it is supposed to show a custom field from the product rather than from the checkout.

If you need a field from the checkout like you wrote in your initial post, check out the documentation here:
Displaying a custom field

Or if you need to display a custom field from the product like that snippet (looks like this may be where you got that?):
Displaying product custom fields

Hope that helps!
