New button on Product Page

Hi. How can I add a new button on the Product page to link to an externat url or to an article of my Joomla site? (the same for all products)

Thanks.

Hi,

You can edit the view "product / show_default" and add the desired button in the page template.
This view is accessible from the menu Display > Views.

Hi, thanks for the reply. I'm not very familiar with some php code, but I tried to add the new button with a similar code than the 'contact us' button. The button appears ok but I don't know how to set the parameters to the 'displayButton' function. Please, Can you tell me a little sample of a call from this function to an external link (' www.google.es ')? Could it be oppened in a new window?

<div id="hikashop_product_contact_main" class="hikashop_product_contact_main">
<?php
  echo $this->cart->displayButton('New Button Text', 'contact_us', $params, '', '');
?>
</div>
