Ok, in way of an update, I’ve done a bit more investigation and discovered the following. Using <?php echo get_field('custom_bg', $product->ID); ?> correctly displays the image from the custom field – YAY!
However, this only works on certain products! Right now, during testing, I only have two active Woocommerce products, with IDs 98 and 106. I’ve added some debug code to the page so I know what the current page ID is at any time. When I visit product 106, the debug code correctly shows 106, and the custom_bg field is displayed. And when I visit product 98 I see 98 in the debug code but no custom_bg field displays. What’s most perplexing is when I visit my Woocommerce Shop page, the debug code shows 98.
Is this expected behaviour? Is the ID clash what’s stopping the custom_bg field from displaying?
I’m going to add another product to see if it displays there…
