Hello,

 

It is displayed in a file product.tpl and product-list.tpl three times with different type

 

Try as in my example:

    public function hookdisplayProductPriceBlock($params)
    {

        if ($params['type'] != 'old_price') {
            return;
        }
     $this->context->smarty->assign(
         array(
             'my_module_name' => Configuration::get('HELLOWORLD_NAME'),
                 'comment' => Configuration::get('HELLOWORLD_NAME1'),
             'my_module_link' => $this->context->link->getModuleLink('helloworld', 'display')
         )
     );
     return $this->display(__FILE__, 'helloworld.tpl');
    } 

hree times with different parameters
