Ok, so now that we have custom fields appearing in the back end / product editor, on closer inspection we’re seeing another issue… some of our custom fields are storing arrays of information. Namely, we’ve got a few fields using the select2 input type, which are using the multiple custom attribute:

'custom_attributes' => array( 'multiple' => 'multiple' )

These fields are still not appearing in the back end editor; additionally, when we use the recommended code in the functions.php file:

add_action('woocommerce_product_meta_start', 'wcv_food_type', 2);
function wcv_food_type() {
    $food_type = get_post_meta( get_the_ID(), 'wcv_custom_product_food_type', true ); // Set the meta key
    echo 'Food Type: ' . $food_type . '<br>';
}

The field value appears on the front end Product page simply as the text “Array,” rather than the values of that array which are obviously what we’re hoping to see.

Any suggestions here? Might this be a place where we’d need to integrate ACF to get additional functionality? We’re trying to avoid that if possible.

Thanks again!
