Show Reference near to cart button (and refresh it)

[AETtec]

Hello.

Im so newbie at php and i want show the reference of each product on a near/visible place around button add to cart and price. So

so i did the next modification:

My version of PS is 1.7.6.1

1) File "only-reference.tpl" created on next location: /themes/newyork_home1/templates/catalog/_partials/only-reference.tpl
and writed the next code inside the file:

    {if isset($product.reference_to_display)}
      <div class="product-reference">
        <label class="label">{l s='Reference' d='Shop.Theme.Catalog'} </label>
        <span itemprop="sku">{$product.reference_to_display}</span>
      </div>
    {/if}

 

2) Modify the next file: /themes/newyork_home1/templates/catalog/product.tpl
and insert this code:
 

                    {block name='only-reference'}
                    {include file='catalog/_partials/only-reference.tpl'}
                    {/block}

The result...? yes the reference is on the correct place now, but it doesnt refresh when i change to other combination of the product, so i need help to fix it.
Please!

Simple solution.
Create a minimodule and use hookHeader in it.

Probably like this.

public function hookHeader($params)
{                        
   if(Tools::getValue('id_product')) {
        $product_reference= $this->context->product->reference_to_display;
     	$this->context->smarty->assign(array(
                    'my_reference_to_display' => product_reference,
     	));
   }               
}

 

tpl:

<span itemprop="sku">{$my_reference_to_display}</span>

Or add your tpl var_dump and show variables

{$product|@var_dump}

Thank you for the answer, but i dont know how to create a minimodule, i saw this tool : https://validator.prestashop.com/generator
But i dont know nothing about php, i tried creating one with the tool and editing the php file with the 1º code you shared, then tried to install but it give me an error.
