Show SKU, EAN and UPC products with variants

[Roberto Remondini]

Good evening everyone,
I'm editing a Ps 1.6.1.11 ecommerce made with POS Rossi 3 theme.

I need to show the SKU, EAN13 and UPC code for the items.
I modified the code by adding this:

<p id = "product_reference"{if empty($product->reference) || !$product->reference} style="display: none;" {else} style="display: block !important;" {/if}>
                <label>Codice</label>
                <span class="editable" itemprop="sku" style="font-weight:400;color:#777;">{if !isset($groups)}{$product->reference|escape:'html':'UTF-8'}{/if}</span>
            </p>
        
            <p id = "product_ean13"{if empty($product->ean13) || !$product->ean13} style="display: none;" {else} style="display: block !important;" {/if}>
                <label>{l s='Ean13:'} </label>
                <span {if !empty($product->ean13) && $product->ean13} content="{$product->ean13}"{/if}>{$product->ean13|escape:'html':'UTF-8'}</span>
            </p>
        
            <p id = "product_upc"{if empty($product->upc) || !$product->upc} style="display: none;" {else} style="display: block !important;" {/if}>
                <label>{l s='UPC:'} </label>
                <span {if !empty($product->upc) && $product->upc} content="{$product->upc}"{/if}>{$product->upc|escape:'html':'UTF-8'}</span>
            </p>

It works fine for products without variants but it shows nothing when I go to select a specific product variants (es. size, color, model, etc).

I think is necessary add som javascripts code to update informations when a variant is selected.

Any idea to how to do it?
